How to install Ncurses/Terminfo on your system
|
|
---------------------------------------------------------------------
|
|
|
|
************************************************************
|
|
* READ ALL OF THIS FILE BEFORE YOU TRY TO INSTALL NCURSES. *
|
|
************************************************************
|
|
|
|
You should be reading the file INSTALL in a directory called ncurses-d.d, where
|
|
d.d is the current version number. There should be several subdirectories,
|
|
including `c++', `form', `man', `menu', 'misc', `ncurses', `panel', `progs',
|
|
and `test'. See the README file for a roadmap to the package.
|
|
|
|
If you are a distribution integrator or packager, please read and act on the
|
|
section titled IF YOU ARE A SYSTEM INTEGRATOR below.
|
|
|
|
If you are converting from BSD curses and do not have root access, be sure
|
|
to read the BSD CONVERSION NOTES section below.
|
|
|
|
If you are trying to build applications using gpm with ncurses,
|
|
read the USING NCURSES WITH GPM section below.
|
|
|
|
If you are running over the Andrew File System see the note below on
|
|
USING NCURSES WITH AFS.
|
|
|
|
If you are cross-compiling, see the note below on BUILDING NCURSES WITH A
|
|
CROSS-COMPILER.
|
|
|
|
If you want to build the Ada95 binding, go to the Ada95 directory and
|
|
follow the instructions there. The Ada95 binding is not covered below.
|
|
|
|
|
|
REQUIREMENTS:
|
|
------------
|
|
|
|
You will need the following to build and install ncurses under UNIX:
|
|
|
|
* ANSI C compiler (gcc, for instance)
|
|
* sh (bash will do)
|
|
* awk (mawk or gawk will do)
|
|
* sed
|
|
* BSD or System V style install (a script is enclosed)
|
|
|
|
Ncurses has been also built in the OS/2 EMX environment.
|
|
|
|
|
|
INSTALLATION PROCEDURE:
|
|
----------------------
|
|
|
|
1. First, decide whether you want ncurses to replace your existing library (in
|
|
which case you'll need super-user privileges) or be installed in parallel
|
|
with it.
|
|
|
|
The --prefix option to configure changes the root directory for installing
|
|
ncurses. The default is normally in subdirectories of /usr/local, except
|
|
for systems where ncurses is normally installed as a system library (see
|
|
"IF YOU ARE A SYSTEM INTEGRATOR"). Use --prefix=/usr to replace your
|
|
default curses distribution.
|
|
|
|
The package gets installed beneath the --prefix directory as follows:
|
|
|
|
In $(prefix)/bin: tic, infocmp, captoinfo, tset,
|
|
reset, clear, tput, toe, tabs
|
|
In $(prefix)/lib: libncurses*.* libcurses.a
|
|
In $(prefix)/share/terminfo: compiled terminal descriptions
|
|
In $(prefix)/include: C header files
|
|
Under $(prefix)/man: the manual pages
|
|
|
|
Note that the configure script attempts to locate previous installation of
|
|
ncurses, and will set the default prefix according to where it finds the
|
|
ncurses headers.
|
|
|
|
Do not use commands such as
|
|
|
|
make install prefix=XXX
|
|
|
|
to change the prefix after configuration, since the prefix value is used
|
|
for some absolute pathnames such as TERMINFO. Instead do this
|
|
|
|
make install DESTDIR=XXX
|
|
|
|
See also the discussion of --with-install-prefix.
|
|
|
|
2. Type `./configure' in the top-level directory of the distribution to
|
|
configure ncurses for your operating system and create the Makefiles.
|
|
Besides --prefix, various configuration options are available to customize
|
|
the installation; use `./configure --help' to list the available options.
|
|
|
|
If your operating system is not supported, read the PORTABILITY section in
|
|
the file ncurses/README for information on how to create a configuration
|
|
file for your system.
|
|
|
|
The `configure' script generates makefile rules for one or more object
|
|
models and their associated libraries:
|
|
|
|
libncurses.a (normal)
|
|
|
|
libcurses.a (normal, a link to libncurses.a)
|
|
This gets left out if you configure with --disable-overwrite.
|
|
|
|
libncurses.so (shared)
|
|
|
|
libncurses_g.a (debug)
|
|
|
|
libncurses_p.a (profile)
|
|
|
|
libncurses.la (libtool)
|
|
|
|
If you configure using the --enable-widec option, a "w" is appended to the
|
|
library names (e.g., libncursesw.a), and the resulting libraries support
|
|
wide-characters, e.g., via a UTF-8 locale. The corresponding header files
|
|
are compatible with the non-wide-character configuration; wide-character
|
|
features are provided by ifdef's in the header files. The wide-character
|
|
library interfaces are not binary-compatible with the non-wide-character
|
|
version. Building and running the wide-character code relies on a fairly
|
|
recent implementation of libiconv. We have built this configuration on
|
|
various systems using libiconv, sometimes requiring libutf8.
|
|
|
|
If you configure using the --with-pthread option, a "t" is appended to
|
|
the library names (e.g., libncursest.a, libncursestw.a).
|
|
|
|
If you do not specify any models, the normal and debug libraries will be
|
|
configured. Typing `configure' with no arguments is equivalent to:
|
|
|
|
./configure --with-normal --with-debug --enable-overwrite
|
|
|
|
Typing
|
|
|
|
./configure --with-shared
|
|
|
|
makes the shared libraries the default, resulting in
|
|
|
|
./configure --with-shared --with-normal --with-debug --enable-overwrite
|
|
|
|
If you want only shared libraries, type
|
|
|
|
./configure --with-shared --without-normal --without-debug
|
|
|
|
Rules for generating shared libraries are highly dependent upon the choice
|
|
of host system and compiler. We've been testing shared libraries on
|
|
several systems, but more work needs to be done to make shared libraries
|
|
work on other systems.
|
|
|
|
If you have libtool installed, you can type
|
|
|
|
./configure --with-libtool
|
|
|
|
to generate the appropriate static and/or shared libraries for your
|
|
platform using libtool.
|
|
|
|
You can make curses and terminfo fall back to an existing file of termcap
|
|
definitions by configuring with --enable-termcap. If you do this, the
|
|
library will search /etc/termcap before the terminfo database, and will
|
|
also interpret the contents of the TERM environment variable. See the
|
|
section BSD CONVERSION NOTES below.
|
|
|
|
3. Type `make'. Ignore any warnings, no error messages should be produced.
|
|
This should compile the ncurses library, the terminfo compiler tic(1),
|
|
captoinfo(1), infocmp(1), toe(1), clear(1) tset(1), reset(1), and tput(1)
|
|
programs (see the manual pages for explanation of what they do), some test
|
|
programs, and the panels, menus, and forms libraries.
|
|
|
|
4. Run ncurses and several other test programs in the test directory to
|
|
verify that ncurses functions correctly before doing an install that
|
|
may overwrite system files. Read the file test/README for details on
|
|
the test programs.
|
|
|
|
NOTE: You must have installed the terminfo database, or set the
|
|
environment variable $TERMINFO to point to a SVr4-compatible terminfo
|
|
database before running the test programs. Not all vendors' terminfo
|
|
databases are SVr4-compatible, but most seem to be. Exceptions include
|
|
DEC's Digital Unix (formerly known as OSF/1).
|
|
|
|
If you run the test programs WITHOUT installing terminfo, ncurses may
|
|
read the termcap file and cache that in $HOME/.terminfo, which will
|
|
thereafter be used instead of the terminfo database. See the comments
|
|
on "--enable-getcap-cache", to see why this is a Bad Thing.
|
|
|
|
It is possible to configure ncurses to use other terminfo database formats.
|
|
A few are provided as examples in the include-directory (see --with-caps).
|
|
|
|
The ncurses program is designed specifically to test the ncurses library.
|
|
You can use it to verify that the screen highlights work correctly, that
|
|
cursor addressing and window scrolling works OK, etc.
|
|
|
|
5. Once you've tested, you can type `make install' to install libraries,
|
|
the programs, the terminfo database and the manual pages. Alternately, you
|
|
can type `make install' in each directory you want to install. In the
|
|
top-level directory, you can do a partial install using these commands:
|
|
|
|
'make install.progs' installs tic, infocmp, etc...
|
|
'make install.includes' installs the headers.
|
|
'make install.libs' installs the libraries (and the headers).
|
|
'make install.data' installs the terminfo data. (Note: `tic' must
|
|
be installed before the terminfo data can be
|
|
compiled).
|
|
'make install.man' installs the manual pages.
|
|
|
|
############################################################################
|
|
# CAVEAT EMPTOR: `install.data' run as root will NUKE any existing #
|
|
# terminfo database. If you have any custom or unusual entries SAVE them #
|
|
# before you install ncurses. I have a file called terminfo.custom for #
|
|
# this purpose. Don't forget to run tic on the file once you're done. #
|
|
############################################################################
|
|
|
|
The terminfo(5) manual page must be preprocessed with tbl(1) before
|
|
being formatted by nroff(1). Modern man(1) implementations tend to do
|
|
this by default, but you may want to look at your version's manual page
|
|
to be sure. You may also install the manual pages after preprocessing
|
|
with tbl(1) by specifying the configure option --with-manpage-tbl.
|
|
|
|
If the system already has a curses library that you need to keep using
|
|
you'll need to distinguish between it and ncurses. See the discussion of
|
|
--disable-overwrite. If ncurses is installed outside the standard
|
|
directories (/usr/include and /usr/lib) then all your users will need to
|
|
use the -I option to compile programs and -L to link them.
|
|
|
|
If you have another curses installed in your system and you accidentally
|
|
compile using its curses.h you'll end up with a large number of
|
|
undefined symbols at link time.
|
|
|
|
IF YOU DO NOT HAVE ROOT: Change directory to the `progs' subdirectory
|
|
and run the `capconvert' script. This script will deduce various things
|
|
about your environment and use them to build you a private terminfo tree,
|
|
so you can use ncurses applications.
|
|
|
|
If more than one user at your site does this, the space for the duplicate
|
|
trees is wasted. Try to get your site administrators to install a system-
|
|
wide terminfo tree instead.
|
|
|
|
See the BSD CONVERSION NOTES section below for a few more details.
|
|
|
|
6. The c++ directory has C++ classes that are built on top of ncurses and
|
|
panels. You must have c++ (and its libraries) installed before you can
|
|
compile and run the demo.
|
|
|
|
Use --without-cxx-binding to tell configure to not build the C++ bindings
|
|
and demo.
|
|
|
|
If you do not have C++, you must use the --without-cxx option to tell
|
|
the configure script to not attempt to determine the type of 'bool'
|
|
which may be supported by C++. IF YOU USE THIS OPTION, BE ADVISED THAT
|
|
YOU MAY NOT BE ABLE TO COMPILE (OR RUN) NCURSES APPLICATIONS WITH C++.
|
|
|
|
|
|
SUMMARY OF CONFIGURE OPTIONS:
|
|
----------------------------
|
|
|
|
The configure script provides a short list of its options when you type
|
|
|
|
./configure --help
|
|
|
|
The --help and several options are common to all configure scripts that are
|
|
generated with autoconf. Those are all listed before the line
|
|
|
|
--enable and --with options recognized:
|
|
|
|
The other options are specific to this package. We list them in alphabetic
|
|
order.
|
|
|
|
--disable-assumed-color
|
|
With ncurses 5.1, we introduced a new function, assume_default_colors()
|
|
which allows applications to specify what the default foreground and
|
|
background color are assumed to be. Most color applications use
|
|
full-screen color; but a few do not color the background. While the
|
|
assumed values can be overridden by invoking assume_default_colors(),
|
|
you may find it useful to set the assumed values to the pre-5.1
|
|
convention, using this configure option.
|
|
|
|
--disable-big-core
|
|
Assume machine has little memory. The configure script attempts to
|
|
determine if your machine has enough memory (about 6Mb) to compile the
|
|
terminfo database without writing portions to disk. Some allocators
|
|
return deceptive results, so you may have to override the configure
|
|
script. Or you may be building tic for a smaller machine.
|
|
|
|
--disable-big-strings
|
|
Disable compile-time optimization of predefined tables which puts
|
|
all of their strings into a very long string, to reduce relocation
|
|
overhead.
|
|
|
|
--disable-database
|
|
Use only built-in data. The ncurses libraries normally read terminfo
|
|
and termcap data from disk. You can configure ncurses to have a
|
|
built-in database, aka "fallback" entries. Embedded applications may
|
|
have no need for an external database. Some, but not all of the
|
|
programs are useful in this configuration, e.g., reset and tput versus
|
|
infocmp and tic.
|
|
|
|
--disable-db-install
|
|
Do not install the terminal database. This is used to omit features
|
|
for packages, as done with --without-progs.
|
|
|
|
--disable-ext-funcs
|
|
Disable function-extensions. Configure ncurses without the functions
|
|
that are not specified by XSI. See ncurses/modules for the exact
|
|
list of library modules that would be suppressed.
|
|
|
|
--disable-hashmap
|
|
Compile without hashmap scrolling-optimization code. This algorithm is
|
|
the default.
|
|
|
|
--disable-home-terminfo
|
|
The $HOME/.terminfo directory is normally added to ncurses' search
|
|
list for reading/writing terminfo entries, since that directory is
|
|
more likely writable than the system terminfo database. Use this
|
|
option to disable the feature altogether.
|
|
|
|
--disable-largefile
|
|
Disable compiler flags needed to use large-file interfaces.
|
|
|
|
--disable-libtool-version
|
|
when using --with-libtool, control how the major/minor version numbers
|
|
are used for constructing the library name.
|
|
|
|
The default uses the -version-number feature of libtool, which makes
|
|
the library names compatible (though not identical) with the standard
|
|
build using --with-shared.
|
|
|
|
Use --disable-libtool-version to use the libtool -version-info feature.
|
|
This corresponds to the setting used before patch 20100515.
|
|
|
|
--disable-leaks
|
|
For testing, compile-in code that frees memory that normally would not
|
|
be freed, to simplify analysis of memory-leaks.
|
|
|
|
Any implementation of curses must not free the memory associated with
|
|
a screen, since (even after calling endwin()), it must be available
|
|
for use in the next call to refresh(). There are also chunks of
|
|
memory held for performance reasons. That makes it hard to analyze
|
|
curses applications for memory leaks. To work around this, build
|
|
a debugging version of the ncurses library which frees those chunks
|
|
which it can, and provides the _nc_free_and_exit() function to free
|
|
the remainder on exit. The ncurses utility and test programs use this
|
|
feature, e.g., via the ExitProgram() macro.
|
|
|
|
--disable-lp64
|
|
The header files will ignore use of the _LP64 symbol to make chtype
|
|
and mmask_t types 32 bits (they may be long on 64-bit hosts, for
|
|
compatibility with older releases).
|
|
|
|
NOTE: this is potentially an ABI change, depending on existing
|
|
packages. The default for this option is "disabled" for ncurses
|
|
ABI 5, and "enabled" for ABI 6.
|
|
|
|
--disable-macros
|
|
For testing, use functions rather than macros. The program will run
|
|
more slowly, but it is simpler to debug. This defines NCURSES_NOMACROS
|
|
at build time. See also the --enable-expanded option.
|
|
|
|
--disable-overwrite
|
|
If you are installing ncurses on a system which contains another
|
|
development version of curses, or which could be confused by the loader
|
|
for another version, we recommend that you leave out the link to
|
|
-lcurses. The ncurses library is always available as -lncurses.
|
|
Disabling overwrite also causes the ncurses header files to be
|
|
installed into a subdirectory, e.g., /usr/local/include/ncurses,
|
|
rather than the include directory. This makes it simpler to avoid
|
|
compile-time conflicts with other versions of curses.h
|
|
|
|
--disable-relink
|
|
If --enable-rpath is given, the generated makefiles normally will
|
|
rebuild the libraries during install. Use this option to simply
|
|
copy whatever the linked produced.
|
|
|
|
This option is ignored if --enable-rpath is not given.
|
|
|
|
--disable-root-environ
|
|
Compile with environment restriction, so certain environment variables
|
|
are not available when running as root, or via a setuid/setgid
|
|
application. These are (for example $TERMINFO) those that allow the
|
|
search path for the terminfo or termcap entry to be customized.
|
|
|
|
--disable-rpath-hack
|
|
Normally the configure script helps link libraries found in unusual
|
|
places by adding an rpath option to the link command. If you are
|
|
building packages, this feature may be redundant. Use this option
|
|
to suppress the feature.
|
|
|
|
--disable-scroll-hints
|
|
Compile without scroll-hints code. This option is ignored when
|
|
hashmap scrolling is configured, which is the default.
|
|
|
|
--disable-tic-depends
|
|
When building shared libraries, normally the tic library is linked to
|
|
depend upon the ncurses library (or equivalently, on the tinfo-library
|
|
if the --with-termlib option was given). The tic- and tinfo-library
|
|
ABIs do not depend on the --enable-widec option. Some packagers have
|
|
used this to reduce the number of library files which are packaged by
|
|
using only one copy of those libraries. To make this work properly,
|
|
the tic library must be built without an explicit dependency on the
|
|
underlying library (ncurses vs ncursesw, tinfo vs tinfow). Use this
|
|
configure option to do that.
|
|
For example
|
|
configure --with-ticlib --with-shared --disable-tic-depends
|
|
|
|
--disable-tparm-varargs
|
|
Portable programs should call tparm() using the fixed-length parameter
|
|
list documented in X/Open. ncurses provides varargs support for this
|
|
function. Use --disable-tparm-varargs to disable this support.
|
|
|
|
--enable-assertions
|
|
For testing, compile-in assertion code. This is used only for a few
|
|
places where ncurses cannot easily recover by returning an error code.
|
|
|
|
--enable-broken_linker
|
|
A few platforms have what we consider a broken linker: it cannot link
|
|
objects from an archive solely by referring to data objects in those
|
|
files, but requires a function reference. This configure option
|
|
changes several data references to functions to work around this
|
|
problem.
|
|
|
|
NOTE: With ncurses 5.1, this may not be necessary, since we are
|
|
told that some linkers interpret uninitialized global data as a
|
|
different type of reference which behaves as described above. We have
|
|
explicitly initialized all of the global data to work around the
|
|
problem.
|
|
|
|
--enable-bsdpad
|
|
Recognize BSD-style prefix padding. Some ancient BSD programs (such as
|
|
nethack) call tputs("50") to implement delays.
|
|
|
|
--enable-colorfgbg
|
|
Compile with experimental $COLORFGBG code. That environment variable
|
|
is set by some terminal emulators as a hint to applications, by
|
|
advertising the default foreground and background colors. During
|
|
initialization, ncurses sets color pair 0 to match this.
|
|
|
|
--enable-const
|
|
The curses interface as documented in XSI is rather old, in fact
|
|
including features that precede ANSI C. The prototypes generally do
|
|
not make effective use of "const". When using stricter compilers (or
|
|
gcc with appropriate warnings), you may see warnings about the mismatch
|
|
between const and non-const data. We provide a configure option which
|
|
changes the interfaces to use const - quieting these warnings and
|
|
reflecting the actual use of the parameters more closely. The ncurses
|
|
library uses the symbol NCURSES_CONST for these instances of const,
|
|
and if you have asked for compiler warnings, will add gcc's const-qual
|
|
warning. There will still be warnings due to subtle inconsistencies
|
|
in the interface, but at a lower level.
|
|
|
|
NOTE: configuring ncurses with this option may detract from the
|
|
portability of your applications by encouraging you to use const in
|
|
places where the XSI curses interface would not allow them. Similar
|
|
issues arise when porting to SVr4 curses, which uses const in even
|
|
fewer places.
|
|
|
|
--enable-echo
|
|
Use the option --disable-echo to make the build-log less verbose by
|
|
suppressing the display of the compile and link commands. This makes
|
|
it easier to see the compiler warnings. (You can always use "make -n"
|
|
to see the options that are used).
|
|
|
|
--enable-expanded
|
|
For testing, generate functions for certain macros to make them visible
|
|
as such to the debugger. See also the --disable-macros option.
|
|
|
|
--enable-ext-colors
|
|
Extend the cchar_t structure to allow more than 16 colors to be
|
|
encoded. This applies only to the wide-character (--enable-widec)
|
|
configuration.
|
|
|
|
NOTE: using this option will make libraries which are not binary-
|
|
compatible with libncursesw 5.4. None of the interfaces change, but
|
|
applications which have an array of cchar_t's must be recompiled.
|
|
|
|
--enable-ext-mouse
|
|
Modify the encoding of mouse state to make room for a 5th mouse button.
|
|
That allows one to use ncurses with a wheel mouse with xterm or
|
|
similar X terminal emulators.
|
|
|
|
NOTE: using this option will make libraries which are not binary-
|
|
compatible with libncursesw 5.4. None of the interfaces change, but
|
|
applications which have mouse mask mmask_t's must be recompiled.
|
|
|
|
--enable-getcap
|
|
Use the 4.4BSD getcap code if available, or a bundled version of it to
|
|
fetch termcap entries. Entries read in this way cannot use (make
|
|
cross-references to) the terminfo tree, but it is faster than reading
|
|
/etc/termcap.
|
|
|
|
If configured for one of the *BSD systems, this automatically uses
|
|
the hashed database system produced using cap_mkdb or similar tools.
|
|
In that case, there is no advantage in using the --enable-getcap-cache
|
|
option.
|
|
|
|
See also the --with-hashed-db option.
|
|
|
|
--enable-getcap-cache
|
|
Cache translated termcaps under the directory $HOME/.terminfo
|
|
|
|
NOTE: this sounds good - it makes ncurses run faster the second time.
|
|
But look where the data comes from - an /etc/termcap containing lots of
|
|
entries that are not up to date. If you configure with this option and
|
|
forget to install the terminfo database before running an ncurses
|
|
application, you will end up with a hidden terminfo database that
|
|
generally does not support color and will miss some function keys.
|
|
|
|
--enable-hard-tabs
|
|
Compile-in cursor-optimization code that uses hard-tabs. We would make
|
|
this a standard feature except for the concern that the terminfo entry
|
|
may not be accurate, or that your stty settings have disabled the use
|
|
of tabs.
|
|
|
|
--enable-interop
|
|
Compile-in experimental interop bindings. These provide generic types
|
|
for the form-library.
|
|
|
|
--enable-mixed-case
|
|
Controls whether the filesystem on which the terminfo database resides
|
|
supports mixed-case filenames (normal for UNIX, but not on other
|
|
systems). If you do not specify this option, the configure script
|
|
checks the current filesystem.
|
|
|
|
--enable-no-padding
|
|
Compile-in support for the $NCURSES_NO_PADDING environment variable,
|
|
which allows you to suppress the effect of non-mandatory padding in
|
|
terminfo entries. This is the default, unless you have disabled the
|
|
extended functions.
|
|
|
|
--enable-pc-files
|
|
If pkg-config is found (see --with-pkg-config), generate ".pc" files
|
|
for each of the libraries, and install them in pkg-config's library
|
|
directory.
|
|
|
|
--enable-pthreads-eintr
|
|
add logic in threaded configuration to ensure that a read(2) system
|
|
call can be interrupted for SIGWINCH.
|
|
|
|
--enable-reentrant
|
|
Compile experimental configuration which improves reentrant use of the
|
|
library by reducing global and static variables. This option is also
|
|
set if --with-pthread is used.
|
|
|
|
Enabling this option adds a "t" to the library names, except for the
|
|
special case when --enable-weak-symbols is also used.
|
|
|
|
--enable-rpath
|
|
Use rpath option when generating shared libraries, and (with some
|
|
restrictions) when linking the corresponding programs. This originally
|
|
(in 1997) applied mainly to systems using the GNU linker (read the
|
|
manpage).
|
|
|
|
More recently it is useful for systems that require special treatment
|
|
shared libraries in "unusual" locations. The "system" libraries reside
|
|
in directories which are on the loader's default search-path. While
|
|
you may be able to use workarounds such as the $LD_LIBRARY_PATH
|
|
environment variable, they do not work with setuid applications since
|
|
the LD_LIBRARY_PATH variable would be unset in that situation.
|
|
|
|
This option does not apply to --with-libtool, since libtool makes
|
|
extra assumptions about rpath.
|
|
|
|
--enable-safe-sprintf
|
|
Compile with experimental safe-sprintf code. You may consider using
|
|
this if you are building ncurses for a system that has neither
|
|
vsnprintf() or vsprintf(). It is slow, however.
|
|
|
|
--enable-sigwinch
|
|
Compile support for ncurses' SIGWINCH handler. If your application has
|
|
its own SIGWINCH handler, ncurses will not use its own. The ncurses
|
|
handler causes wgetch() to return KEY_RESIZE when the screen-size
|
|
changes. This option is the default, unless you have disabled the
|
|
extended functions.
|
|
|
|
--enable-signed-char
|
|
The term.h header declares a Booleans[] array typed "char". But it
|
|
stores signed values there and "char" is not necessarily signed.
|
|
Some packagers choose to alter the type of Booleans[] though this
|
|
is not strictly compatible. This option allows one to implement this
|
|
alteration without patching the source code.
|
|
|
|
--enable-sp-funcs
|
|
Compile-in support for extended functions which accept a SCREEN pointer,
|
|
reducing the need for juggling the global SP value with set_term() and
|
|
delscreen().
|
|
|
|
--enable-string-hacks
|
|
Controls whether strlcat and strlcpy may be used. The same issue
|
|
applies to OpenBSD's warnings about snprintf, noting that this function
|
|
is weakly standardized.
|
|
|
|
Aside from stifling these warnings, there is no functional improvement
|
|
in ncurses.
|
|
|
|
--enable-symlinks
|
|
If your system supports symbolic links, make tic use symbolic links
|
|
rather than hard links to save diskspace when writing aliases in the
|
|
terminfo database.
|
|
|
|
--enable-tcap-names
|
|
Compile-in support for user-definable terminal capabilities. Use the
|
|
-x option of tic and infocmp to treat unrecognized terminal
|
|
capabilities as user-defined strings. This option is the default,
|
|
unless you have disabled the extended functions.
|
|
|
|
--enable-term-driver
|
|
Enable experimental terminal-driver. This is currently used for the
|
|
MinGW port, by providing a way to substitute the low-level terminfo
|
|
library with different terminal drivers.
|
|
|
|
--enable-termcap
|
|
Compile in support for reading terminal descriptions from termcap if no
|
|
match is found in the terminfo database. See also the --enable-getcap
|
|
and --enable-getcap-cache options.
|
|
|
|
Termcap support requires run-time parsing rather than loading
|
|
predigested data. If you have specified --with-ticlib, then you
|
|
cannot have termcap support since run-time parsing is done in the
|
|
tic library, which is intentionally not part of normal linkage
|
|
dependencies.
|
|
|
|
--enable-warnings
|
|
Turn on GCC compiler warnings. There should be only a few.
|
|
|
|
--enable-weak-symbols
|
|
If the --with-pthread option is set, check if the compiler supports
|
|
weak-symbols. If it does, then name the thread-capable library without
|
|
the "t" (libncurses rather than libncursest), and provide for
|
|
dynamically loading the pthreads entrypoints at runtime. This allows
|
|
one to reduce the number of library files for ncurses.
|
|
|
|
--enable-wgetch-events
|
|
Compile with experimental wgetch-events code. See ncurses/README.IZ
|
|
|
|
--enable-widec
|
|
Compile with wide-character code. This makes a different version of
|
|
the libraries (e.g., libncursesw.so), which stores characters as
|
|
wide-characters,
|
|
|
|
NOTE: applications compiled with this configuration are not compatible
|
|
with those built for 8-bit characters. You cannot simply make a
|
|
symbolic link to equate libncurses.so with libncursesw.so
|
|
|
|
NOTE: the Ada95 binding may be built against either version of the the
|
|
ncurses library, but you must decide which: the binding installs the
|
|
same set of files for either version. Currently (2002/6/22) it does
|
|
not use the extended features from the wide-character code, so it is
|
|
probably better to not install the binding for that configuration.
|
|
|
|
--enable-xmc-glitch
|
|
Compile-in support experimental xmc (magic cookie) code.
|
|
|
|
--with-abi-version=NUM
|
|
Override the ABI version, which is used in shared library filenames.
|
|
Normally this is the same as the release version; some ports have
|
|
special requirements for compatibility.
|
|
|
|
This option does not affect linking with libtool, which uses the
|
|
release major/minor numbers.
|
|
|
|
--with-ada-compiler=CMD
|
|
Specify the Ada95 compiler command (default "gnatmake")
|
|
|
|
--with-ada-include=DIR
|
|
Tell where to install the Ada includes (default:
|
|
PREFIX/lib/ada/adainclude)
|
|
|
|
--with-ada-objects=DIR
|
|
Tell where to install the Ada objects (default: PREFIX/lib/ada/adalib)
|
|
|
|
--with-ada-sharedlib
|
|
Build a shared library for Ada95 binding, if the compiler permits.
|
|
|
|
NOTE: You must also set the --with-shared option on some platforms
|
|
for a successful build. You need not use this option when you set
|
|
--with-shared, unless you want to use the Ada shared library.
|
|
|
|
--with-bool=TYPE
|
|
If --without-cxx is specified, override the type used for the "bool"
|
|
declared in curses.h (normally the type is automatically chosen to
|
|
correspond with that in <stdbool.h>, or defaults to platform-specific
|
|
sizes).
|
|
|
|
--with-build-cpp=XXX
|
|
This option is provided by the same macro used for $BUILD_CC, etc.,
|
|
but is not directly used by ncurses.
|
|
|
|
--with-build-cc=XXX
|
|
If cross-compiling, specify a host C compiler, which is needed to
|
|
compile a few utilities which generate source modules for ncurses.
|
|
If you do not give this option, the configure script checks if the
|
|
$BUILD_CC variable is set, and otherwise defaults to gcc or cc.
|
|
|
|
--with-build-cflags=XXX
|
|
If cross-compiling, specify the host C compiler-flags. You might need
|
|
to do this if the target compiler has unusual flags which confuse the
|
|
host compiler.
|
|
|
|
You can also set the environment variable $BUILD_CFLAGS rather than
|
|
use this option.
|
|
|
|
--with-build-cppflags=XXX
|
|
If cross-compiling, specify the host C preprocessor-flags. You might
|
|
need to do this if the target compiler has unusual flags which confuse
|
|
the host compiler.
|
|
|
|
You can also set the environment variable $BUILD_CPPFLAGS rather than
|
|
use this option.
|
|
|
|
--with-build-ldflags=XXX
|
|
If cross-compiling, specify the host linker-flags. You might need to
|
|
do this if the target linker has unusual flags which confuse the host
|
|
compiler.
|
|
|
|
You can also set the environment variable $BUILD_LDFLAGS rather than
|
|
use this option.
|
|
|
|
--with-build-libs=XXX
|
|
If cross-compiling, the host libraries. You might need to do this if
|
|
the target environment requires unusual libraries.
|
|
|
|
You can also set the environment variable $BUILD_LIBS rather than
|
|
use this option.
|
|
|
|
--with-caps=XXX
|
|
Specify an alternate terminfo capabilities file, which makes the
|
|
configure script look for "include/Caps.XXX". A few systems, e.g.,
|
|
AIX 4.x use the same overall file-format as ncurses for terminfo
|
|
data, but use different alignments within the tables to support
|
|
legacy applications. For those systems, you can configure ncurses
|
|
to use a terminfo database which is compatible with the native
|
|
applications.
|
|
|
|
--with-ccharw-max=XXX
|
|
Override the size of the wide-character array in cchar_t structures.
|
|
Changing this will alter the binary interface. This defaults to 5.
|
|
|
|
--with-chtype=TYPE
|
|
Override type of chtype, which stores the video attributes and (if
|
|
--enable-widec is not given) a character. Prior to ncurses 5.5, this
|
|
was always unsigned long, but with ncurses 5.5, it may be unsigned.
|
|
Use this option if you need to preserve compatibility with 64-bit
|
|
executables, e.g., by setting "--with-chtype=long" (the configure
|
|
script supplies "unsigned").
|
|
|
|
--with-cxx-shared
|
|
When --with-shared is set, build libncurses++ as a shared library.
|
|
This implicitly relies upon building with gcc/g++, since other
|
|
compiler suites may have differences in the way shared libraries are
|
|
built. libtool by the way has similar limitations.
|
|
|
|
--with-database=XXX
|
|
Specify the terminfo source file to install. Usually you will wish
|
|
to install ncurses' default (misc/terminfo.src). Certain systems
|
|
have special requirements, e.g, OS/2 EMX has a customized terminfo
|
|
source file.
|
|
|
|
--with-dbmalloc
|
|
For testing, compile and link with Conor Cahill's dbmalloc library.
|
|
This also sets the --disable-leaks option.
|
|
|
|
--with-debug
|
|
Generate debug-libraries (default). These are named by adding "_g"
|
|
to the root, e.g., libncurses_g.a
|
|
|
|
--with-default-terminfo-dir=XXX
|
|
Specify the default terminfo database directory. This is normally
|
|
DATADIR/terminfo, e.g., /usr/share/terminfo.
|
|
|
|
--with-dmalloc
|
|
For testing, compile and link with Gray Watson's dmalloc library.
|
|
This also sets the --disable-leaks option.
|
|
|
|
--with-fallbacks=XXX
|
|
Specify a list of fallback terminal descriptions which will be
|
|
compiled into the ncurses library. See CONFIGURING FALLBACK ENTRIES.
|
|
|
|
--with-gpm
|
|
use Alessandro Rubini's GPM library to provide mouse support on the
|
|
Linux console. Prior to ncurses 5.5, this introduced a dependency on
|
|
the GPM library.
|
|
|
|
Currently ncurses uses the dlsym() function to bind to the library at
|
|
runtime, so it is only necessary that the library be present when
|
|
ncurses is built, to obtain the filename (or soname) used in the
|
|
corresponding dlopen() call. If you give a value for this option,
|
|
e.g.,
|
|
|
|
--with-gpm=$HOME/tmp/test-gpm.so
|
|
|
|
that overrides the configure check for the soname.
|
|
|
|
See also --without-dlsym
|
|
|
|
--with-hashed-db[=XXX]
|
|
Use a hashed database for storing terminfo data rather than storing
|
|
each compiled entry in a separate binary file within a directory
|
|
tree.
|
|
|
|
In particular, this uses the Berkeley database 1.8.5 interface, as
|
|
provided by that and its successors db 2, 3, and 4. The actual
|
|
interface is slightly different in the successor versions of the
|
|
Berkeley database. The database should have been configured using
|
|
"--enable-compat185".
|
|
|
|
If you use this option for configuring ncurses, tic will only be able
|
|
to write entries in the hashed database. infocmp can still read
|
|
entries from a directory tree as well as reading entries from the
|
|
hashed database. To do this, infocmp determines whether the $TERMINFO
|
|
variable points to a directory or a file, and reads the directory-tree
|
|
or hashed database respectively.
|
|
|
|
You cannot have a directory containing both hashed-database and
|
|
filesystem-based terminfo entries.
|
|
|
|
Use the parameter value to give the install-prefix used for the
|
|
datbase, e.g.,
|
|
--with-hashed-db=/usr/local/BigBase
|
|
to find the corresponding include- and lib-directories under the
|
|
given directory.
|
|
|
|
See also the --enable-getcap option.
|
|
|
|
--with-install-prefix=XXX
|
|
Allows you to specify an alternate location for installing ncurses
|
|
after building it. The value you specify is prepended to the "real"
|
|
install location. This simplifies making binary packages. The
|
|
makefile variable DESTDIR is set by this option. It is also possible
|
|
to use
|
|
make install DESTDIR=XXX
|
|
since the makefiles pass that variable to subordinate makes.
|
|
|
|
NOTE: a few systems build shared libraries with fixed pathnames; this
|
|
option probably will not work for those configurations.
|
|
|
|
--with-lib-prefix=XXX
|
|
OS/2 EMX used a different naming convention from most Unix-like
|
|
platforms. It required that the "lib" part of a library name was
|
|
omitted. Newer EMX as part of eComStation does not follow that
|
|
convention. Use this option to override the configure script's
|
|
assumptions about the library-prefix. If this option is omitted, it
|
|
uses the original OS/2 EMX convention for that platform. Use
|
|
"--with-lib-prefix=lib" for the newer EMX in eComStation. Use
|
|
"--without-lib-prefix" to suppress it for other odd platforms.
|
|
|
|
--with-libtool[=XXX]
|
|
Generate libraries with libtool. If this option is selected, then it
|
|
overrides all other library model specifications. Note that libtool
|
|
must already be installed, uses makefile rules dependent on GNU make,
|
|
and does not promise to follow the version numbering convention of
|
|
other shared libraries on your system. However, if the --with-shared
|
|
option does not succeed, you may get better results with this option.
|
|
|
|
If a parameter value is given, it must be the full pathname of the
|
|
particular version of libtool, e.g.,
|
|
/usr/bin/libtool-1.2.3
|
|
|
|
It is possible to rebuild the configure script to use the automake
|
|
macros for libtool, e.g., AC_PROG_LIBTOOL. See the comments in
|
|
aclocal.m4 for CF_PROG_LIBTOOL, and ensure that you build configure
|
|
using the appropriate patch for autoconf from
|
|
http://invisible-island.net/autoconf/
|
|
|
|
--with-manpage-aliases
|
|
Tell the configure script you wish to create entries in the
|
|
man-directory for aliases to manpages which list them, e.g., the
|
|
functions in the panel manpage. This is the default. You can disable
|
|
it if your man program does this. You can also disable
|
|
--with-manpage-symlinks to install files containing a ".so" command
|
|
rather than symbolic links.
|
|
|
|
--with-manpage-format=XXX
|
|
Tell the configure script how you would like to install man-pages. The
|
|
option value must be one of these: gzip, compress, BSDI, normal,
|
|
formatted. If you do not give this option, the configure script
|
|
attempts to determine which is the case.
|
|
|
|
--with-manpage-renames=XXX
|
|
Tell the configure script that you wish to rename the manpages while
|
|
installing. Currently the only distribution which does this is Debian.
|
|
The option value specifies the name of a file that lists the renamed
|
|
files, e.g., $srcdir/man/man_db.renames
|
|
|
|
--with-manpage-symlinks
|
|
Tell the configure script that you wish to make symbolic links in the
|
|
man-directory for aliases to the man-pages. This is the default, but
|
|
can be disabled for systems that provide this automatically. Doing
|
|
this on systems that do not support symbolic links will result in
|
|
copying the man-page for each alias.
|
|
|
|
--with-manpage-tbl
|
|
Tell the configure script that you with to preprocess the manpages
|
|
by running them through tbl to generate tables understandable by
|
|
nroff.
|
|
|
|
--with-mmask-t=TYPE
|
|
Override type of mmask_t, which stores the mouse mask. Prior to
|
|
ncurses 5.5, this was always unsigned long, but with ncurses 5.5, it
|
|
may be unsigned. Use this option if you need to preserve compatibility
|
|
with 64-bit executables.
|
|
|
|
--with-normal
|
|
Generate normal (i.e., static) libraries (default).
|
|
|
|
Note: on Linux, the configure script will attempt to use the GPM
|
|
library via the dlsym() function call. Use --without-dlsym to disable
|
|
this feature, or --without-gpm, depending on whether you wish to use
|
|
GPM.
|
|
|
|
--with-ospeed=TYPE
|
|
Override type of ospeed variable, which is part of the termcap
|
|
compatibility interface. In termcap, this is a 'short', which works
|
|
for a wide range of baudrates because ospeed is not the actual speed
|
|
but the encoded value, e.g., B9600 would be a small number such as 13.
|
|
However the encoding scheme originally allowed for values "only" up to
|
|
38400bd. A newer set of definitions past 38400bd is not encoded as
|
|
compactly, and is not guaranteed to fit into a short (see the function
|
|
cfgetospeed(), which returns a speed_t for this reason). In practice,
|
|
applications that required knowledge of the ospeed variable, i.e.,
|
|
those using termcap, do not use the higher speeds. Your application
|
|
(or system, in general) may or may not.
|
|
|
|
--with-pkg-config=[DIR]
|
|
Check for pkg-config, optionally specifying its path.
|
|
|
|
--with-pkg-config-libdir=[DIR]
|
|
If pkg-config was found, override the automatic check for its library
|
|
path.
|
|
|
|
--with-profile
|
|
Generate profile-libraries These are named by adding "_p" to the root,
|
|
e.g., libncurses_p.a
|
|
|
|
--with-pthread
|
|
Link with POSIX threads, set --enable-reentrant. The use_window() and
|
|
use_screen() functions will use mutex's, allowing rudimentary support
|
|
for multithreaded applications.
|
|
|
|
--with-rcs-ids
|
|
Compile-in RCS identifiers. Most of the C files have an identifier.
|
|
|
|
--with-rel-version=NUM
|
|
Override the release version, which may be used in shared library
|
|
filenames. This consists of a major and minor version number separated
|
|
by ".". Normally the major version number is the same as the ABI
|
|
version; some ports have special requirements for compatibility.
|
|
|
|
--with-shared
|
|
Generate shared-libraries. The names given depend on the system for
|
|
which you are building, typically using a ".so" suffix, along with
|
|
symbolic links that refer to the release version.
|
|
|
|
NOTE: Unless you override the configure script by setting the $CFLAGS
|
|
environment variable, these will not be built with the -g debugging
|
|
option.
|
|
|
|
NOTE: For some configurations, e.g., installing a new version of
|
|
ncurses shared libraries on a machine which already has ncurses
|
|
shared libraries, you may encounter problems with the linker.
|
|
For example, it may prevent you from running the build tree's
|
|
copy of tic (for installing the terminfo database) because it
|
|
loads the system's copy of the ncurses shared libraries. In that
|
|
case, using the misc/shlib script may be helpful, since it sets
|
|
$LD_LIBRARY_PATH to point to the build tree, e.g.,
|
|
./misc/shlib make install
|
|
|
|
NOTE: If you use the --with-ada-sharedlib option, you should also
|
|
set this option, to ensure that C-language modules needed for the
|
|
Ada binding use appropriate compiler options.
|
|
|
|
--with-shlib-version=XXX
|
|
Specify whether to use the release or ABI version for shared libraries.
|
|
This is normally chosen automatically based on the type of system
|
|
which you are building on. We use it for testing the configure script.
|
|
|
|
--with-sysmouse
|
|
use FreeBSD sysmouse interface provide mouse support on the console.
|
|
|
|
--with-system-type=XXX
|
|
For testing, override the derived host system-type which is used to
|
|
decide things such as the linker commands used to build shared
|
|
libraries. This is normally chosen automatically based on the type of
|
|
system which you are building on. We use it for testing the configure
|
|
script.
|
|
|
|
--with-terminfo-dirs=XXX
|
|
Specify a search-list of terminfo directories which will be compiled
|
|
into the ncurses library (default: DATADIR/terminfo)
|
|
|
|
--with-termlib[=XXX]
|
|
When building the ncurses library, organize this as two parts: the
|
|
curses library (libncurses) and the low-level terminfo library
|
|
(libtinfo). This is done to accommodate applications that use only
|
|
the latter. The terminfo library is about half the size of the total.
|
|
|
|
If an option value is given, that overrides the name of the terminfo
|
|
library. For instance, if the wide-character version is built, the
|
|
terminfo library would be named libtinfow. But the libtinfow interface
|
|
is upward compatible from libtinfo, so it would be possible to overlay
|
|
libtinfo.so with a "wide" version of libtinfow.so by renaming it with
|
|
this option.
|
|
|
|
--with-termpath=XXX
|
|
Specify a search-list of termcap files which will be compiled into the
|
|
ncurses library (default: /etc/termcap:/usr/share/misc/termcap)
|
|
|
|
--with-ticlib[=XXX]
|
|
When building the ncurses library, build a separate library for
|
|
the modules that are used only by the utility programs. Normally
|
|
those would be bundled with the termlib or ncurses libraries.
|
|
|
|
If an option value is given, that overrides the name of the tic
|
|
library. As in termlib, there is no ABI difference between the
|
|
"wide" libticw.so and libtic.so
|
|
|
|
NOTE: Overriding the name of the tic library may be useful if you are
|
|
also using the --with-termlib option to rename libtinfo. If you are
|
|
not doing that, renaming the tic library can result in conflicting
|
|
library dependencies for tic and other programs built with the tic
|
|
library.
|
|
|
|
--with-tparm-arg[=XXX]
|
|
Override the type used for tparm() arguments, which normally is a
|
|
"long". However the function must assume that its arguments can hold a
|
|
pointer to char's which is not always workable for 64-bit platforms. A
|
|
better choice would be intptr_t, which was not available at the time
|
|
tparm's interface was defined.
|
|
|
|
If the option is not given, this defaults to "long".
|
|
|
|
--with-trace
|
|
Configure the trace() function as part of the all models of the ncurses
|
|
library. Normally it is part of the debug (libncurses_g) library only.
|
|
|
|
--with-xterm-kbs=XXX
|
|
Configure xterm's terminfo entries to use either BS (^H, i.e., ASCII
|
|
backspace) or DEL (^?, or 127). XXX can be BS (or bs, 8) or DEL
|
|
(or del, 127).
|
|
|
|
During installation, the makefile and scripts modifies the "xterm+kbs"
|
|
terminfo entry to use this setting.
|
|
|
|
--with-valgrind
|
|
For testing, compile with debug option.
|
|
This also sets the --disable-leaks option.
|
|
|
|
--with-wrap-prefix=XXX
|
|
When using the --enable-reentrant option, ncurses redefines variables
|
|
that would be global in curses, e.g., LINES, as a macro that calls a
|
|
"wrapping" function which fetches the data from the current SCREEN
|
|
structure. Normally that function is named by prepending "_nc_" to the
|
|
variable's name. The function is technically private (since portable
|
|
applications would not refer directly to it). But according to one
|
|
line of reasoning, it is not the same type of "private" as functions
|
|
which applications should not call even via a macro. This configure
|
|
option lets you choose the prefix for these wrapped variables.
|
|
|
|
--without-ada
|
|
Suppress the configure script's check for Ada95, do not build the
|
|
Ada95 binding and related demo.
|
|
|
|
--without-curses-h
|
|
Don't install the ncurses header with the name "curses.h". Rather,
|
|
install as "ncurses.h" and modify the installed headers and manpages
|
|
accordingly.
|
|
|
|
Likewise, do not install an alias "curses" for the ncurses manpage.
|
|
|
|
--without-cxx
|
|
XSI curses declares "bool" as part of the interface. C++ also declares
|
|
"bool". Neither specifies the size and type of booleans, but both
|
|
insist on the same name. We chose to accommodate this by making the
|
|
configure script check for the size and type (e.g., unsigned or signed)
|
|
that your C++ compiler uses for booleans. If you do not wish to use
|
|
ncurses with C++, use this option to tell the configure script to not
|
|
adjust ncurses bool to match C++.
|
|
|
|
--without-cxx-binding
|
|
Suppress the configure script's check for C++, do not build the
|
|
C++ binding and related demo.
|
|
|
|
--without-develop
|
|
Disable development options. This does not include those that change
|
|
the interface, such as --enable-widec.
|
|
|
|
--without-dlsym
|
|
Do not use dlsym() to load GPM dynamically.
|
|
|
|
--without-manpages
|
|
Tell the configure script to suppress the install of ncurses' manpages.
|
|
|
|
--without-progs
|
|
Tell the configure script to suppress the build of ncurses' application
|
|
programs (e.g., tic). The test applications will still be built if you
|
|
type "make", though not if you simply do "make install".
|
|
|
|
--without-tests
|
|
Tell the configure script to suppress the build of ncurses' test
|
|
programs.
|
|
|
|
--without-xterm-new
|
|
Tell the configure script to use "xterm-old" for the entry used in
|
|
the terminfo database. This will work with variations such as
|
|
X11R5 and X11R6 xterm.
|
|

|
COMPATIBILITY WITH OLDER VERSIONS OF NCURSES:
|
|
--------------------------------------------
|
|
|
|
Because ncurses implements the X/Open Curses Specification, its interface
|
|
is fairly stable. That does not mean the interface does not change.
|
|
Changes are made to the documented interfaces when we find differences
|
|
between ncurses and X/Open or implementations which they certify (such as
|
|
Solaris). We add extensions to those interfaces to solve problems not
|
|
addressed by the original curses design, but those must not conflict with
|
|
the X/Open documentation.
|
|
|
|
Here are some of the major interface changes, and related problems which
|
|
you may encounter when building a system with different versions of
|
|
ncurses:
|
|
|
|
5.8 (Feb 26, 2011)
|
|
Interface changes:
|
|
|
|
+ add an alternate library configuration, i.e., "terminal driver" to
|
|
support port to Windows, built with MinGW. There are two drivers
|
|
(terminfo and Windows console). The terminfo driver works on other
|
|
platforms.
|
|
|
|
+ add a new set of functions which accept a SCREEN* parameter, in
|
|
contrast with the original set which use the global value "sp".
|
|
By default, these names end with "_sp", and are otherwise
|
|
functionally identical with the originals.
|
|
|
|
In addition to the "_sp" functions, there are a few new functions
|
|
associated with this feature: ceiling_panel, ground_panel,
|
|
new_prescr.
|
|
|
|
If the library is not built with the sp-funcs extension, there
|
|
are no related interface changes.
|
|
|
|
+ add tiparm function based on review of X/Open Curses Issue 7.
|
|
|
|
+ change internal _nc_has_mouse function to public has_mouse function
|
|
|
|
Added extensions:
|
|
|
|
+ add a few more functions to support the NCURSES_OPAQUE feature:
|
|
get_escdelay, is_pad, is_subwin
|
|
|
|
Added internal functions (other than "_sp" variants):
|
|
_nc_curscr_of
|
|
_nc_format_slks
|
|
_nc_get_alias_table
|
|
_nc_get_hash_info
|
|
_nc_insert_wch
|
|
_nc_newscr_of
|
|
_nc_outc_wrapper
|
|
_nc_retrace_char
|
|
_nc_retrace_int_attr_t
|
|
_nc_retrace_mmask_t
|
|
_nc_setup_tinfo
|
|
_nc_stdscr_of
|
|
_nc_tinfo_cmdch
|
|
|
|
Removed internal functions:
|
|
_nc_makenew (some configurations replace by _nc_makenew_sp)
|
|
|
|
Modified internal functions:
|
|
_nc_UpdateAttrs
|
|
_nc_get_hash_table
|
|
_nc_has_mouse
|
|
_nc_insert_ch
|
|
_nc_wgetch
|
|
|
|
5.7 (November 2, 2008)
|
|
Interface changes:
|
|
|
|
+ generate linkable stubs for some macros:
|
|
getattrs
|
|
|
|
+ Add new library configuration for tic-library (the non-curses portion
|
|
of the ncurses library used for the tic program as well as some
|
|
others such as tack. There is no API change, but makefiles would be
|
|
changed to use the tic-library built separately.
|
|
|
|
tack, distributed separately from ncurses, uses some of the internal
|
|
_nc_XXX functions, which are declared in the tic.h header file.
|
|
|
|
The reason for providing this separate library is that none of the
|
|
functions in it are suitable for threaded applications.
|
|
|
|
+ Add new library configuration (ncursest, ncurseswt) which provides
|
|
rudimentary support for POSIX threads. This introduces opaque
|
|
access functions to the WINDOW structure and adds a parameter to
|
|
several internal functions.
|
|
|
|
+ move most internal variables (except tic-library) into data blocks
|
|
_nc_globals and _nc_prescreen to simplify analysis. Those were
|
|
globally accessible, but since they were not part of the documented
|
|
API, there is no ABI change.
|
|
|
|
+ changed static tables of strings to be indices into long strings, to
|
|
improve startup performance. This changes parameter lists for some
|
|
of the internal functions.
|
|
|
|
Added extensions:
|
|
|
|
+ add NCURSES_OPAQUE definition in curses.h to control whether internal
|
|
details of the WINDOW structure are visible to an application. This
|
|
is always defined when the threaded library is built, and is optional
|
|
otherwise. New functions for this: is_cleared, is_idcok, is_idlok,
|
|
is_immedok, is_keypad, is_leaveok, is_nodelay, is_notimeout,
|
|
is_scrollok, is_syncok, wgetparent and wgetscrreg.
|
|
|
|
+ the threaded library (ncursest) also disallows direct updating of
|
|
global curses-level variables, providing functions (via macros) for
|
|
obtaining their value. A few of those variables can be modified by
|
|
the application, using new functions: set_escdelay, set_tabsize
|
|
|
|
+ added functions use_window() and use_screen() which wrap a mutex
|
|
(if threading is configured) around a call to a user-supplied
|
|
function.
|
|
|
|
Added internal functions:
|
|
_nc_get_alias_table
|
|
_nc_get_screensize
|
|
_nc_keyname
|
|
_nc_screen_of
|
|
_nc_set_no_padding
|
|
_nc_tracechar
|
|
_nc_tracemouse
|
|
_nc_unctrl
|
|
_nc_ungetch
|
|
|
|
These are used for leak-testing, and are stubs for
|
|
ABI compatibility when ncurses is not configured for that
|
|
using the --disable-leaks configure script option:
|
|
|
|
_nc_free_and_exit
|
|
_nc_leaks_tinfo
|
|
|
|
Removed internal functions:
|
|
none
|
|
|
|
Modified internal functions:
|
|
_nc_fifo_dump
|
|
_nc_find_entry
|
|
_nc_handle_sigwinch
|
|
_nc_init_keytry
|
|
_nc_keypad
|
|
_nc_locale_breaks_acs
|
|
_nc_timed_wait
|
|
_nc_update_screensize
|
|
|
|
Use new typedef TRIES to replace "struct tries":
|
|
|
|
_nc_add_to_try
|
|
_nc_expand_try
|
|
_nc_remove_key
|
|
_nc_remove_string
|
|
_nc_trace_tries
|
|
|
|
5.6 (December 17, 2006)
|
|
Interface changes:
|
|
|
|
+ generate linkable stubs for some macros:
|
|
|
|
getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy, getparx,
|
|
getpary, getpary,
|
|
|
|
and (for libncursesw)
|
|
|
|
wgetbkgrnd
|
|
|
|
Added extensions:
|
|
nofilter()
|
|
use_legacy_coding()
|
|
|
|
Added internal functions:
|
|
_nc_first_db
|
|
_nc_get_source
|
|
_nc_handle_sigwinch
|
|
_nc_is_abs_path
|
|
_nc_is_dir_path
|
|
_nc_is_file_path
|
|
_nc_keep_tic_dir
|
|
_nc_keep_tic_dir
|
|
_nc_last_db
|
|
_nc_next_db
|
|
_nc_read_termtype
|
|
_nc_tic_dir
|
|
|
|
Also (if using the hashed database configuration):
|
|
|
|
_nc_db_close
|
|
_nc_db_first
|
|
_nc_db_get
|
|
_nc_db_have_data
|
|
_nc_db_have_index
|
|
_nc_db_next
|
|
_nc_db_open
|
|
_nc_db_put
|
|
|
|
otherwise
|
|
|
|
_nc_hashed_db
|
|
|
|
Removed internal functions:
|
|
none
|
|
|
|
Modified internal functions:
|
|
_nc_add_to_try
|
|
_nc_do_color
|
|
_nc_expand_try
|
|
_nc_remove_key
|
|
_nc_setupscreen
|
|
|
|
5.5 (October 10, 2005)
|
|
Interface changes:
|
|
|
|
+ terminfo installs "xterm-new" as "xterm" entry rather than
|
|
"xterm-old" (aka xterm-r6).
|
|
|
|
+ terminfo data is installed using the tic -x option (few systems
|
|
still use ncurses 4.2).
|
|
|
|
+ modify C++ binding to work with newer C++ compilers by providing
|
|
initializers and using modern casts. Old-style header names are
|
|
still used in this release to allow compiling with not-so-old
|
|
compilers.
|
|
|
|
+ form and menu libraries now work with wide-character data.
|
|
Applications which bypassed the form library and manipulated the
|
|
FIELD.buf data directly will not work properly with libformw, since
|
|
that no longer points to an array of char. The set_field_buffer()
|
|
and field_buffer() functions translate to/from the actual field
|
|
data.
|
|
|
|
+ change SP->_current_attr to a pointer, adjust ifdef's to ensure that
|
|
libtinfo.so and libtinfow.so have the same ABI. The reason for this
|
|
is that the corresponding data which belongs to the upper-level
|
|
ncurses library has a different size in each model.
|
|
|
|
+ winnstr() now returns multibyte character strings for the
|
|
wide-character configuration.
|
|
|
|
+ assume_default_colors() no longer requires that use_default_colors()
|
|
be called first.
|
|
|
|
+ data_ahead() now works with wide-characters.
|
|
|
|
+ slk_set() and slk_wset() now accept and store multibyte or
|
|
multicolumn characters.
|
|
|
|
+ start_color() now returns OK if colors have already been started.
|
|
start_color() also returns ERR if it cannot allocate memory.
|
|
|
|
+ pair_content() now returns -1 for consistency with init_pair() if it
|
|
corresponds to the default-color.
|
|
|
|
+ unctrl() now returns null if its parameter does not correspond
|
|
to an unsigned char.
|
|
|
|
Added extensions:
|
|
Experimental mouse version 2 supports wheel mice with buttons
|
|
4 and 5. This requires ABI 6 because it modifies the encoding
|
|
of mouse events.
|
|
|
|
Experimental extended colors allows encoding of 256 foreground
|
|
and background colors, e.g., with the xterm-256color or
|
|
xterm-88color terminfo entries. This requires ABI 6 because
|
|
it changes the size of cchar_t.
|
|
|
|
Added internal functions:
|
|
_nc_check_termtype2
|
|
_nc_resolve_uses2
|
|
_nc_retrace_cptr
|
|
_nc_retrace_cvoid_ptr
|
|
_nc_retrace_void_ptr
|
|
_nc_setup_term
|

|
Modified internal functions:

|
_nc_insert_ch
|
|
_nc_save_str
|
|
_nc_trans_string
|
|
|
|
5.4 (February 8, 2004)
|
|
Interface changes:
|
|
|
|
+ add the remaining functions for X/Open curses wide-character support.
|
|
These are only available if the library is configured using the
|
|
--enable-widec option.
|
|
pecho_wchar()
|
|
slk_wset()
|
|
|
|
+ write getyx() and related 2-return macros in terms of getcury(),
|
|
getcurx(), etc.
|
|
|
|
+ simplify ifdef for bool declaration in curses.h
|
|
|
|
+ modify ifdef's in curses.h that disabled use of __attribute__() for
|
|
g++, since recent versions implement the cases which ncurses uses.
|
|
|
|
+ change some interfaces to use const:
|
|
define_key()
|
|
mvprintw()
|
|
mvwprintw()
|
|
printw()
|
|
vw_printw()
|

Modified internal functions:
|
|
_nc_remove_string()
|
|
_nc_retrace_chtype()
|
|
|
|
5.3 (October 12, 2002)
|
|
Interface changes:
|
|
|
|
+ change type for bool used in headers to NCURSES_BOOL, which usually
|
|
is the same as the compiler's definition for 'bool'.
|
|
|
|
+ add all but two functions for X/Open curses wide-character support.
|
|
These are only available if the library is configured using the
|
|
--enable-widec option. Missing functions are
|
|
pecho_wchar()
|
|
slk_wset()
|
|
|
|
+ add environment variable $NCURSES_ASSUMED_COLORS to modify the
|
|
assume_default_colors() extension.
|
|
|
|
Added extensions:
|

Removed internal functions:
|
|
_nc_background()
|
|
|
|
Modified internal functions:
|
|
_nc_freeall() debug
|
|
|
|
5.2 (October 21, 2000)
|
|
Interface changes:
|
|
|
|
+ revert termcap ospeed variable to 'short' (see discussion of the
|
|
--with-ospeed configure option).

5.1 (July 8, 2000)
|
|
Interface changes:
|
|
|
|
+ made the extended terminal capabilities
|
|
(configure --enable-tcap-names) a standard feature. This should
|
|
be transparent to applications that do not require it.
|
|
|
|
+ removed the trace() function and related trace support from the
|
|
production library.
|
|
|
|
+ modified curses.h.in, undef'ing some symbols to avoid conflict
|
|
with C++ STL.
|
|
|
|
Added extensions: assume_default_colors().
|
|
|
|
5.0 (October 23, 1999)
|
|
Interface changes:
|
|
|
|
+ implemented the wcolor_set() and slk_color() functions.
|
|
|
|
+ move macro winch to a function, to hide details of struct ldat
|
|
|
|
+ corrected prototypes for slk_* functions, using chtype rather than
|
|
attr_t.
|
|
|
|
+ the slk_attr_{set,off,on} functions need an additional void*
|
|
parameter according to XSI.
|
|
|
|
+ modified several prototypes to correspond with 1997 version of X/Open
|
|
Curses: [w]attr_get(), [w]attr_set(), border_set() have different
|
|
parameters. Some functions were renamed or misspelled:
|
|
erase_wchar(), in_wchntr(), mvin_wchntr(). Some developers have used
|
|
attr_get().
|
|
|
|
Added extensions: keybound(), curses_version().
|
|
|
|
Terminfo database changes:
|
|
|
|
+ change translation for termcap 'rs' to terminfo 'rs2', which is
|
|
the documented equivalent, rather than 'rs1'.
|
|
|
|
The problems are subtler in recent releases.
|
|
|
|
a) This release provides users with the ability to define their own
|
|
terminal capability extensions, like termcap. To accomplish this,
|
|
we redesigned the TERMTYPE struct (in term.h). Very few
|
|
applications use this struct. They must be recompiled to work with
|
|
the 5.0 library.
|
|
|
|
a) If you use the extended terminfo names (i.e., you used configure
|
|
--enable-tcap-names), the resulting terminfo database can have some
|
|
entries which are not readable by older versions of ncurses. This
|
|
is a bug in the older versions:
|
|
|
|
+ the terminfo database stores booleans, numbers and strings in
|
|
arrays. The capabilities that are listed in the arrays are
|
|
specified by X/Open. ncurses recognizes a number of obsolete and
|
|
extended names which are stored past the end of the specified
|
|
entries.
|
|
|
|
+ a change to read_entry.c in 951001 made the library do an lseek()
|
|
call incorrectly skipping data which is already read from the
|
|
string array. This happens when the number of strings in the
|
|
terminfo data file is greater than STRCOUNT, the number of
|
|
specified and obsolete or extended strings.
|
|
|
|
+ as part of alignment with the X/Open final specification, in the
|
|
990109 patch we added two new terminfo capabilities:
|
|
set_a_attributes and set_pglen_inch). This makes the indices for
|
|
the obsolete and extended capabilities shift up by 2.
|
|
|
|
+ the last two capabilities in the obsolete/extended list are memu
|
|
and meml, which are found in most terminfo descriptions for xterm.
|
|
|
|
When trying to read this terminfo entry, the spurious lseek()
|
|
causes the library to attempt to read the final portion of the
|
|
terminfo data (the text of the string capabilities) 4 characters
|
|
past its starting point, and reads 4 characters too few. The
|
|
library rejects the data, and applications are unable to
|
|
initialize that terminal type.
|
|
|
|
FIX: remove memu and meml from the xterm description. They are
|
|
obsolete, not used by ncurses. (It appears that the feature was
|
|
added to xterm to make it more like hpterm).
|
|
|
|
This is not a problem if you do not use the -x option of tic to
|
|
create a terminfo database with extended names. Note that the
|
|
user-defined terminal capabilities are not affected by this bug,
|
|
since they are stored in a table after the older terminfo data ends,
|
|
and are invisible to the older libraries.
|
|
|
|
c) Some developers did not wish to use the C++ binding, and used the
|
|
configure --without-cxx option. This causes problems if someone
|
|
uses the ncurses library from C++ because that configure test
|
|
determines the type for C++'s bool and makes ncurses match it, since
|
|
both C++ and curses are specified to declare bool. Calling ncurses
|
|
functions with the incorrect type for bool will cause execution
|
|
errors. In 5.0 we added a configure option "--without-cxx-binding"
|
|
which controls whether the binding itself is built and installed.
|
|
|
|
4.2 (March 2, 1998)
|
|
Interface changes:
|
|
|
|
+ correct prototype for termattrs() as per XPG4 version 2.
|
|
|
|
+ add placeholder prototypes for color_set(), erasewchar(),
|
|
term_attrs(), wcolor_set() as per XPG4 version 2.
|
|
|
|
+ add macros getcur[xy] getbeg[xy] getpar[xy], which are defined in
|
|
SVr4 headers.
|
|
|
|
New extensions: keyok() and define_key().
|
|
|
|
Terminfo database changes:
|
|
|
|
+ corrected definition in curses.h for ACS_LANTERN, which was 'I'
|
|
rather than 'i'.
|
|
|
|
4.1 (May 15, 1997)
|
|
|
|
We added these extensions: use_default_colors(). Also added
|
|
configure option --enable-const, to support the use of const where
|
|
X/Open should have, but did not, specify.
|
|
|
|
The terminfo database content changed the representation of color for
|
|
most entries that use ANSI colors. SVr4 curses treats the setaf/setab
|
|
and setf/setb capabilities differently, interchanging the red/blue
|
|
colors in the latter.
|
|
|
|
4.0 (December 24, 1996)
|
|
|
|
We bumped to version 4.0 because the newly released Linux dynamic
|
|
loader (ld.so.1.8.5) did not load shared libraries whose ABI and REL
|
|
versions were inconsistent. At that point, ncurses ABI was 3.4 and the
|
|
REL was 1.9.9g, so we made them consistent.
|
|
|
|
1.9.9g (December 1, 1996)
|
|
|
|
This fixed most of the problems with 1.9.9e, and made these interface
|
|
changes:
|
|
|
|
+ remove tparam(), which had been provided for compatibility with
|
|
some termcap. tparm() is standard, and does not conflict with
|
|
application's fallback for missing tparam().
|
|
|
|
+ turn off hardware echo in initscr(). This changes the sense of the
|
|
echo() function, which was initialized to echoing rather than
|
|
nonechoing (the latter is specified). There were several other
|
|
corrections to the terminal I/O settings which cause applications to
|
|
behave differently.
|
|
|
|
+ implemented several functions (such as attr_on()) which were
|
|
available only as macros.
|
|
|
|
+ corrected several typos in curses.h.in (i.e., the mvXXXX macros).
|
|
|
|
+ corrected prototypes for delay_output(),
|
|
has_color, immedok() and idcok().
|
|
|
|
+ corrected misspelled getbkgd(). Some applications used the
|
|
misspelled name.
|
|
|
|
+ added _yoffset to WINDOW. The size of WINDOW does not impact
|
|
applications, since they use only pointers to WINDOW structs.
|
|
|
|
These changes were made to the terminfo database:
|
|
|
|
+ removed boolean 'getm' which was available as an extended name.
|
|
|
|
We added these extensions: wresize(), resizeterm(), has_key() and
|
|
mcprint().
|
|
|
|
1.9.9e (March 24, 1996)
|
|
|
|
not recommended (a last-minute/untested change left the forms and
|
|
menus libraries unusable since they do not repaint the screen).
|
|
Foreground/background colors are combined incorrectly, working properly
|
|
only on a black background. When this was released, the X/Open
|
|
specification was available only in draft form.
|
|
|
|
Some applications (such as lxdialog) were "fixed" to work with the
|
|
incorrect color scheme.
|
|
|
|

|
IF YOU ARE A SYSTEM INTEGRATOR:
|
|
------------------------------
|
|
|
|
Configuration and Installation:
|
|
|
|
On platforms where ncurses is assumed to be installed in /usr/lib,
|
|
the configure script uses "/usr" as a default:
|
|
|
|
GNU/Linux, FreeBSD, NetBSD, OpenBSD, Cygwin
|
|
|
|
For other platforms, the default is "/usr/local". See the discussion
|
|
of the "--disable-overwrite" option.
|
|
|
|
The location of the terminfo is set indirectly by the "--datadir"
|
|
configure option, e.g., /usr/share/terminfo, given a datadir of
|
|
/usr/share. You may want to override this if you are installing
|
|
ncurses libraries in nonstandard locations, but wish to share the
|
|
terminfo database.
|
|
|
|
Normally the ncurses library is configured in a pure-terminfo mode;
|
|
that is, with the --disable-termcap option. This makes the ncurses
|
|
library smaller and faster. The ncurses library includes a termcap
|
|
emulation that queries the terminfo database, so even applications that
|
|
use raw termcap to query terminal characteristics will win (providing
|
|
you recompile and relink them!).
|
|
|
|
If you must configure with termcap fallback enabled, you may also wish
|
|
to use the --enable-getcap option. This speeds up termcap-based
|
|
startups, at the expense of not allowing personal termcap entries to
|
|
reference the terminfo tree. See comments in
|
|
ncurses/tinfo/read_termcap.c for further details.
|
|
|
|
Note that if you have $TERMCAP set, ncurses will use that value
|
|
to locate termcap data. In particular, running from xterm will
|
|
set $TERMCAP to the contents of the xterm's termcap entry.
|
|
If ncurses sees that, it will not examine /etc/termcap.
|
|
|
|
Keyboard Mapping:
|
|
|
|
The terminfo file assumes that Shift-Tab generates \E[Z (the ECMA-48
|
|
reverse-tabulation sequence) rather than ^I. Here are the loadkeys -d
|
|
mappings that will set this up:
|
|
|
|
keycode 15 = Tab Tab
|
|
alt keycode 15 = Meta_Tab
|
|
shift keycode 15 = F26
|
|
string F26 ="\033[Z"
|
|
|
|
Naming the Console Terminal
|
|
|
|
In various systems there has been a practice of designating the system
|
|
console driver type as `console'. Please do not do this! It
|
|
complicates peoples' lives, because it can mean that several different
|
|
terminfo entries from different operating systems all logically want to
|
|
be called `console'.
|
|
|
|
Please pick a name unique to your console driver and set that up
|
|
in the /etc/inittab table or local equivalent. Send the entry to the
|
|
terminfo maintainer (listed in the misc/terminfo file) to be included
|
|
in the terminfo file, if it's not already there. See the
|
|
term(7) manual page included with this distribution for more on
|
|
conventions for choosing type names.
|
|
|
|
Here are some recommended primary console names:
|
|
|
|
linux -- Linux console driver
|
|
freebsd -- FreeBSD
|
|
netbsd -- NetBSD
|
|
bsdos -- BSD/OS
|
|
|
|
If you are responsible for integrating ncurses for one of these
|
|
distributions, please either use the recommended name or get back
|
|
to us explaining why you don't want to, so we can work out nomenclature
|
|
that will make users' lives easier rather than harder.
|
|
|
|
|
|
RECENT XTERM VERSIONS:
|
|
---------------------
|
|
|
|
The terminfo database file included with this distribution assumes you
|
|
are running a modern xterm based on XFree86 (i.e., xterm-new). The
|
|
earlier X11R6 entry (xterm-r6) and X11R5 entry (xterm-r5) is provided
|
|
as well. See the --without-xterm-new configure script option if you
|
|
are unable to update your system.
|
|
|
|
|
|
CONFIGURING FALLBACK ENTRIES:
|
|
----------------------------
|
|
|
|
In order to support operation of ncurses programs before the terminfo
|
|
tree is accessible (that is, in single-user mode or at OS installation
|
|
time) the ncurses library can be compiled to include an array of
|
|
pre-fetched fallback entries. This must be done on a machine which
|
|
has ncurses' infocmp and terminfo database installed (as well as
|
|
ncurses' tic and infocmp programs).
|
|
|
|
These entries are checked by setupterm() only when the conventional
|
|
fetches from the terminfo tree and the termcap fallback (if configured)
|
|
have been tried and failed. Thus, the presence of a fallback will not
|
|
shadow modifications to the on-disk entry for the same type, when that
|
|
entry is accessible.
|
|
|
|
By default, there are no entries on the fallback list. After you have
|
|
built the ncurses suite for the first time, you can change the list
|
|
(the process needs infocmp(1)). To do so, use the script
|
|
ncurses/tinfo/MKfallback.sh. The configure script option
|
|
--with-fallbacks does this (it accepts a comma-separated list of the
|
|
names you wish, and does not require a rebuild).
|
|
|
|
If you wanted (say) to have linux, vt100, and xterm fallbacks, you
|
|
might use the commands
|
|
|
|
cd ncurses;
|
|
tinfo/MKfallback.sh \
|
|
$TERMINFO \
|
|
../misc/terminfo.src \
|
|
`which tic` \
|
|
linux vt100 xterm >fallback.c
|
|
|
|
The first three parameters of the script are normally supplied by
|
|
the configured makefiles via the "--with-fallbacks" option. They
|
|
are
|
|
|
|
1) the location of the terminfo database
|
|
2) the source for the terminfo entries
|
|
3) the location of the tic program, used to create a terminfo
|
|
database.
|
|
|
|
Then just rebuild and reinstall the library as you would normally.
|
|
You can restore the default empty fallback list with
|
|
|
|
tinfo/MKfallback.sh \
|
|
$TERMINFO \
|
|
../misc/terminfo.src \
|
|
`which tic` \
|
|
>fallback.c
|
|
|
|
The overhead for an empty fallback list is one trivial stub function.
|
|
Any non-empty fallback list is const-ed and therefore lives in sharable
|
|
text space. You can look at the comment trailing each initializer in
|
|
the generated ncurses/fallback.c file to see the core cost of the
|
|
fallbacks. A good rule of thumb for modern vt100-like entries is that
|
|
each one will cost about 2.5K of text space.
|
|
|
|
|
|
BSD CONVERSION NOTES:
|
|
--------------------
|
|
|
|
If you need to support really ancient BSD programs, you probably
|
|
want to configure with the --enable-bsdpad option. What this does
|
|
is enable code in tputs() that recognizes a numeric prefix on a
|
|
capability as a request for that much trailing padding in milliseconds.
|
|
There are old BSD programs that do things like tputs("50").
|
|
|
|
(If you are distributing ncurses as a support-library component of
|
|
an application you probably want to put the remainder of this section
|
|
in the package README file.)
|
|
|
|
The following note applies only if you have configured ncurses with
|
|
--enable-termcap.
|
|
|
|
------------------------------- CUT HERE --------------------------------
|
|
|
|
If you are installing this application privately (either because you
|
|
have no root access or want to experiment with it before doing a root
|
|
installation), there are a couple of details you need to be aware of.
|
|
They have to do with the ncurses library, which uses terminfo rather
|
|
than termcap for describing terminal characteristics.
|
|
|
|
Though the ncurses library is terminfo-based, it will interpret your
|
|
TERMCAP variable (if present), any local termcap files you reference
|
|
through it, and the system termcap file. However, in order to avoid
|
|
slowing down your application startup, it will only do this once per
|
|
terminal type!
|
|
|
|
The first time you load a given terminal type from your termcap
|
|
database, the library initialization code will automatically write it
|
|
in terminfo format to a subdirectory under $HOME/.terminfo. After
|
|
that, the initialization code will find it there and do a (much
|
|
faster) terminfo fetch.
|
|
|
|
Usually, all this means is that your home directory will silently grow
|
|
an invisible .terminfo subdirectory which will get filled in with
|
|
terminfo descriptions of terminal types as you invoke them. If anyone
|
|
ever installs a global terminfo tree on your system, this will quietly
|
|
stop happening and your $HOME/.terminfo will become redundant.
|
|
|
|
The objective of all this logic is to make converting from BSD termcap
|
|
as painless as possible without slowing down your application (termcap
|
|
compilation is expensive).
|
|
|
|
If you don't have a TERMCAP variable or custom personal termcap file,
|
|
you can skip the rest of this dissertation.
|
|
|
|
If you *do* have a TERMCAP variable and/or a custom personal termcap file
|
|
that defines a terminal type, that definition will stop being visible
|
|
to this application after the first time you run it, because it will
|
|
instead see the terminfo entry that it wrote to $HOME/terminfo the
|
|
first time around.
|
|
|
|
Subsequently, editing the TERMCAP variable or personal TERMCAP file
|
|
will have no effect unless you explicitly remove the terminfo entry
|
|
under $HOME/terminfo. If you do that, the entry will be recompiled
|
|
from your termcap resources the next time it is invoked.
|
|
|
|
To avoid these complications, use infocmp(1) and tic(1) to edit the
|
|
terminfo directory directly.
|
|
|
|
------------------------------- CUT HERE --------------------------------
|
|
|
|
USING NCURSES WITH AFS:
|
|
AFS treats each directory as a separate logical filesystem, you
|
|
can't hard-link across them. The --enable-symlinks option copes
|
|
with this by making tic use symbolic links.
|
|
|
|
USING NCURSES WITH GPM:
|
|
Ncurses 4.1 and up can be configured to use GPM (General Purpose Mouse)
|
|
which is used with Linux console. Be aware that GPM is commonly
|
|
installed as a shared library which contains a wrapper for the curses
|
|
wgetch() function (libcurses.o). Some integrators have simplified
|
|
linking applications by combining all or part of libcurses.so into the
|
|
libgpm.so file, producing symbol conflicts with ncurses (specifically
|
|
the wgetch function). This was originally the BSD curses, but
|
|
generally whatever curses library exists on the system.
|
|
|
|
You may be able to work around this problem by linking as follows:
|
|
|
|
cc -o foo foo.o -lncurses -lgpm -lncurses
|
|
|
|
but the linker may not cooperate, producing mysterious errors.
|
|
See the FAQ, as well as the discussion under the --with-gpm option:
|
|
|
|
http://invisible-island.net/ncurses/ncurses.faq.html#using_gpm_lib
|
|
|
|
BUILDING NCURSES WITH A CROSS-COMPILER
|
|
Ncurses can be built with a cross-compiler. Some parts must be built
|
|
with the host's compiler since they are used for building programs
|
|
(e.g., ncurses/make_hash and ncurses/make_keys) that generate tables
|
|
that are compiled into the ncurses library. The essential thing to do
|
|
is set the BUILD_CC environment variable to your host's compiler, and
|
|
run the configure script configuring for the cross-compiler.
|
|
|
|
The configure options --with-build-cc, etc., are provided to make this
|
|
simpler. Since make_hash and make_keys use only ANSI C features, it
|
|
is normally not necessary to provide the other options such as
|
|
--with-build-libs, but they are provided for completeness.
|
|
|
|
Note that all of the generated source-files which are part of ncurses
|
|
will be made if you use
|
|
|
|
make sources
|
|
|
|
This would be useful in porting to an environment which has little
|
|
support for the tools used to generate the sources, e.g., sed, awk and
|
|
Bourne-shell.
|
|
|
|
When ncurses has been successfully cross-compiled, you may want to use
|
|
"make install" (with a suitable target directory) to construct an
|
|
install tree. Note that in this case (as with the --with-fallbacks
|
|
option), ncurses uses the development platform's tic to do the
|
|
"make install.data" portion.
|
|
|
|
The system's tic program is used to install the terminal database,
|
|
even for cross-compiles. For best results, the tic program should
|
|
be from the most current version of ncurses.
