freebsd-nq/contrib/cvs/INSTALL

First, read the README file.  If you're still happy...

First you need to obtain and install the CVS executables.  If you got
a distribution which contains executables, consult the installation
instructions for that distribution.  If you got source code, do not
panic.  On many platforms building CVS from source code is a
straightforward process requiring no programming knowledge.  See the
section BUILDING FROM SOURCE CODE at the end of this file, which
includes a list of platforms which have been tested.

-------------------------------------------------------------------------------

1) Take a look at the CVS documentation, if desired.  For most
   purposes you want doc/cvs.texinfo, also known as _Version Management
   with CVS_ by Per Cederqvist et al.  Looking at it might be as simple
   as "info cvs" but this will depend on your installation; see README
   for more details.

   See what CVS can do for you, and if it fits your environment (or can
   possibly be made to fit your environment).  If things look good,
   continue on.  Alternately, just give CVS a try first then figure out
   what it is good for.

2) Set the CVSROOT environment variable to where you want to put your
   source repository.  See the "Setting up the repository" section of
   the Cederqvist manual for details, but the quick summary is just to
   pick some directory.  We'll use /src/master as an example.  For
   users of a POSIX shell (sh/bash/ksh) on unix, the following
   commands can be placed in user's ~/.profile, ~/.bash_profile file;
   or in the site-wide /etc/profile:

       CVSROOT=/src/master; export CVSROOT

   For C shell users on unix place the following commands in the
   user's ~/.cshrc, ~/.login, or /etc/chsrc file:

       setenv CVSROOT /src/master

   For Windows users, supposing the repository will be in
   d:\src\master, place the following line in c:\autoexec.bat.  On
   Windows 95, autoexec.bat might not already exist.  In that case,
   just create a new file containing the following line.

       set CVSROOT=:local:d:\src\master

   If these environment variables are not already set in your current
   shell, set them now by typing the above line at the command prompt
   (or source the login script you just edited).
   The instructions for the remaining steps assume that you have set
   the CVSROOT environment variable.

3) Create the master source repository.  Again, the details are in
   the "Setting up the repository" section of cvs.texinfo; the
   one-line summary is:

       $ cvs init

   In this and subsequent examples we use "$" to indicate the command
   prompt; do not type the "$".

4) It might be a good idea to jump right in and put some sources or
   documents directly under CVS control.  From within the top-level
   directory of your source tree, run the following commands:

       $ cvs import -m "test distribution" ccvs CVS_DIST CVS-TEST

   (Those last three items are, respectively, a repository location, a
   "vendor tag", and a "release tag".  You don't need to understand
   them yet, but read the section "Starting new projects" in the
   Cederqvist manual for details).

5) Having done step 4, one should be able to checkout a fresh copy of the
   sources you just imported and hack away at the sources with the
   following command:

      $ cd
      $ cvs checkout ccvs

   This will make the directory "ccvs" in your current directory and
   populate it with the appropriate files and directories.

6) You may wish to customize the various administrative files, in particular
   modules.  See the Cederqvist manual for details.

7) Read the NEWS file to see what's new.

8) Hack away.

BUILDING FROM SOURCE CODE

Tested platforms

CVS has been tested on the following platforms.  The most recent
version of CVS reported to have been tested is indicated, but more
recent versions of CVS probably will work too.  Please send updates to
this list to bug-cvs@gnu.org (doing so in the form of a diff
to this file, or at least exact suggested text, is encouraged).
"tested" means, at a minimum, that CVS compiles and appears to work on
simple (manual) testing.  In many cases it also means "make check"
and/or "make remotecheck" passes, but we don't try to list the
platforms for which that is true.

(footnote 2)
	Some Irix 4.0 systems may core dump in malloc while running
	CVS.  We believe this is a bug in the Irix malloc.  You can
	workaround this bug by linking with "-lmalloc" if necessary.
	(about 1.4A2).

(footnote 4) Comment out the include of sys/time.h in src/server.c. (1.4.93)
	You also may have to make sure TIME_WITH_SYS_TIME is undef'ed.

(footnote 5) Change /usr/tmp to /var/tmp in src/server.c (2 places) (1.4.93).
	(This should no longer be needed; CVS doesn't have /usr/tmp in
	src/server.c any more.  Has anyone tried a more recent version
	on BSDI?  If so, please report it so we can update this file).

(footnote 6) Build in ucb universe with COFF compiler tools.  Put
	/usr/local/bin first in PATH while doing a configure, make
	and install of GNU diffutils-2.7, rcs-5.7, then cvs-1.5.

(footnote 7) Manoj Srivastava <srivasta@pilgrim.umass.edu> reports
        success with this configure command:
  CC=cc CFLAGS='-O2 -Olimit 2000 -std1' ./configure --verbose alpha-dec-osf

(footnote 8) Manoj Srivastava <srivasta@pilgrim.umass.edu> reports
        success with this configure command:
  CC=cc CFLAGS='+O2 -Aa -D_HPUX_SOURCE' ./configure --verbose hppa1.1-hp-hpux

(footnote 9) 
    Had to configure with ./configure --host=<arch>-lynx.

    In src/cvs.h, protected the waitpid prototype with ifdef _POSIX_SOURCE.
    (I might try building with gcc -mposix -D_POSIX_SOURCE.)

    LynxOS has <dirent.h>, but you don't want to use it.
    You want to use <sys/dir.h> instead.
    So after running configure I had to undef HAVE_DIRENT_H and
    define HAVE_SYS_DIR_H.

(footnote 10)
    Had to compile with "make LIBS=-lbsd" (to get gethostbyname
    and getservbyname).

(footnote 11)
    when I do a `cvs init' I get this message:
      ci: 'RCS/loginfo,v' is not a regular file
      ci:  RCS/loginfo,v: Invalid argument
      cvs [init aborted]: failed to checkin n:/safe/CVSROOT/loginfo

-------------------------------------------------------------------------------

Building from source code under Unix:

1)  Run "configure":

	$ ./configure

    You can specify an alternate destination to override the default with
    the --prefix option:

	$ ./configure --prefix=/usr/local/gnu

    or some path that is more appropriate for your site.  The default prefix
    value is "/usr/local", with binaries in sub-directory "bin", manual
    pages in sub-directory "man", and libraries in sub-directory "lib".

    A normal build of CVS will create an executable which supports
    local, server, or client CVS (if you don't know the difference,
    it is described in the Repository chapter of doc/cvs.texinfo).  If
    you do not intend to use client or server CVS, you may want to
    prevent these features from being included in the executable you
    build. You can do this with the --disable-client and
    --disable-server options:

	$ ./configure --disable-client --disable-server

    Typically this can reduce the size of the executable by around 30%.

    Unlike previous versions of CVS, you do not need to install RCS
    or GNU diff.  

    NOTE: The configure program will cache the results of the previous
    configure execution.  If you need to re-run configure from scratch, you
    may need to run "make distclean" first to remove the cached
    configuration information.

    If you are using gcc and are planning to modify CVS, you may want to
    configure with -Wall; see the file HACKING for details.

    If you have Kerberos 4 installed, you can specify the location of
    the header files and libraries using the --with-krb4=DIR option.
    DIR should be a directory with subdirectories include and lib
    holding the Kerberos 4 header files and libraries, respectively.
    The default value is /usr/kerberos.

    If you want to enable support for encryption over Kerberos, use
    the --enable-encryption option.  This option is disabled by
    default.

    Try './configure --help' for further information on its usage.

    NOTE ON CVS's USE OF NDBM:

	By default, CVS uses some built-in ndbm emulation code to allow
	CVS to work in a heterogeneous environment.  However, if you have
	a very large modules database, this may not work well.  You will
	need to edit src/options.h to turn off the MY_NDBM #define and
	re-run configure.  If you do this, the following comments apply.
	If not, you may safely skip these comments.

	If you configure CVS to use the real ndbm(3) libraries and
	you do not have them installed in a "normal" place, you will
	probably want to get the GNU version of ndbm (gdbm) and install
	that before running the CVS configure script.  Be aware that the
	GDBM 1.5 release does NOT install the <ndbm.h> header file included
	with the release automatically.  You may have to install it by hand.

	If you configure CVS to use the ndbm(3) libraries, you cannot
	compile CVS with GNU cc (gcc) on Sun-4 SPARC systems.  However, gcc
	2.0 may have fixed this limitation if -fpcc-struct-return is
	defined.  When using gcc on other systems to compile CVS, you *may*
	need to specify the -fpcc-struct-return option to gcc (you will
	*know* you have to if "cvs checkout" core dumps in some ndbm
	function).  You can do this as follows:

	    $ CC='gcc -fpcc-struct-return' ./configure

	for sh, bash, and ksh users and:

	    % setenv CC 'gcc -fpcc-struct-return'
	    % ./configure

	for csh and tcsh users.

    END OF NOTE FOR NDBM GUNK.

2)  Edit src/options.h.  The defaults should be reasonable, and in fact
    if you are lazy you can safely skip this step.

3)  Try to build it:

	$ make

    This will (hopefully) make the needed CVS binaries within the
    "src" directory.  If something fails for your system, and you want
    to submit a bug report, you may wish to include your
    "config.status" file, your host type, operating system and
    compiler information, make output, and anything else you think
    will be helpful.

3a)  Run the regression tests (optional).

    You may also wish to validate the correctness of the new binary by
    running the regression tests.  If they succeed, that is nice to
    know.  However, if they fail, it doesn't tell you much.  Often it
    will just be a problem with running the tests on your machine,
    rather than a problem with CVS.  Unless you will have the time to
    determine which of the two it is in case of failure, you might
    want to save yourself the time and just not run the tests.

    If you want to run the tests, see the file TESTS for more information.

4)  Install the binaries/documentation:

	$ make install

    Depending on your installation's configuration, you may need to be
    root to do this.

-------------------------------------------------------------------------------

Detailed information about your interaction with "configure":

The "configure" script and its interaction with its options and the
environment is described here.  For more detailed documentation about
"configure", please refer to the GNU Autoconf documentation.

Supported options are:

	--srcdir=DIR		Useful for compiling on many different
				machines sharing one source tree.
	--prefix=DIR		The root of where to install the
				various pieces of CVS (/usr/local).
	--exec_prefix=DIR	If you want executables in a
				host-dependent place and shared
				things in a host-independent place.

The following environment variables override configure's default
behaviour:

	CC			If not set, tries to use gcc first,
				then cc.  Also tries to use "-g -O"
				as options, backing down to -g
				alone if that doesn't work.
	INSTALL			If not set, tries to use "install", then
				"./install-sh" as a final choice.
	RANLIB			If not set, tries to determine if "ranlib"
				is available, choosing "echo" if it doesn't
				appear to be.
	YACC			If not set, tries to determine if "bison"
				is available, choosing "yacc" if it doesn't
				appear to be.

-------------------------------------------------------------------------------

Building from source code under Windows NT/95:

You may find interesting information in windows-NT/README.

1) Using Microsoft Visual C++ 5.x, open the project `cvsnt.dsp',
   in the top directory of the CVS distribution.  If you have an older
   version of Visual C++, take a look at windows-NT/README.
2) Choose "Build cvs.exe" from the "Project" menu.
3) MSVC will place the executable file cvs.exe in WinRel, or whatever
   your target directory is.

-------------------------------------------------------------------------------

Building from source code under other platforms:

For OS/2, see os2/README and emx/README.

For VMS, see README.VMS

For Macintosh, see macintosh/README.MacCVS

For a Java client, see jCVS (which is a separate package from CVS
itself, but which might be preferable to the Macintosh port mentioned
above, for example).
