|
|
dnl -----------------
|
|
dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
|
|
dnl character-strings.
|
|
dnl
|
|
dnl It is ambiguous because the specification accommodated the pre-ANSI
|
|
dnl compilers bundled by more than one vendor in lieu of providing a standard C
|
|
dnl compiler other than by costly add-ons. Because of this, the specification
|
|
dnl did not take into account the use of const for telling the compiler that
|
|
dnl string literals would be in readonly memory.
|
|
dnl
|
|
dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
|
|
dnl let the compiler decide how to represent Xt's strings which were #define'd.
|
|
dnl That does not solve the problem of using the block of Xt's strings which
|
|
dnl are compiled into the library (and is less efficient than one might want).
|
|
dnl
|
|
dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
|
|
dnl when compiling the library and compiling using the library, to tell the
|
|
dnl compiler that String is const.

dnl Look for the ncurses library. This is a little complicated on Linux,

dnl because it may be linked with the gpm (general purpose mouse) library.
|

dnl Some distributions have gpm linked with (bsd) curses, which makes it
|
|
dnl unusable with ncurses. However, we don't want to link with gpm unless
|
|
dnl ncurses has a dependency, since gpm is normally set up as a shared library,
|
|
dnl and the linker will record a dependency.
|

dnl
|
|
dnl The optional parameter gives the root name of the library, in case it is
|
|
dnl not installed as the default curses library. That is how the

dnl wide-character version of ncurses is installed.

|
dnl libraries are compiled in ../../lib
|
|
dnl
|
|
dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
|
|
dnl to install symbolic links to the rel/abi versions of shared libraries.
|
|
dnl
|
|
dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi

dnl version when making symbolic links.
