configure script to "bash" ported to AIX 4.1. (about 1.4A2).
(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 3)
There are some warnings about pointer casts which can safely be
ignored. (about 1.4.90).
(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).
(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) Ralf E. Stranzenbach <ralf@reswi.ruhr.de>
I've made some modifications to "filesubr.c" to deal with NFS
mounted directories (and those funny .nfs* files). This patch
should be used whenever the programmers "sandbox" is located on
a NFS mounted device --- at least on NeXTSTEP.
-------------------------------------------------------------------------------
Installation 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".
If you are using server or local CVS, RCS needs to be installed in
the user's PATH (or a path you have configured in src/options.h,
or a path specified with the -b option). If you don't have RCS,
you will need to get it from GNU as well. It is best to get the
version 5.7 (or later) version of RCS, available from
prep.ai.mit.edu in the file pub/gnu/rcs-5.7.tar.gz.
If you want version control of files with binary data, make sure
that the RCS configure script finds GNU diff 1.15 or later and
notices that diff supports the -a option. CVS itself is much less
picky about which version of diff it uses, and you shouldn't need
to worry about that.
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.
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. Appropriate things to look at may be the
invocation locations of programs like DIFF and GREP.
Also glance at the default values for the environment variables
that CVS uses, in particular, the RCSBIN variable, which holds the
path to where the RCS programs live on your system.
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:
$ make check
Note that if your /bin/sh doesn't support shell functions, you'll
have to try something like this, where "/bin/sh5" is replaced by the
pathname of a shell which handles normal shell functions:
$ make SHELL=/bin/sh5 check
WARNING: This test can take quite a while to run, esp. if your
disks are slow or over-loaded.
If you receive any un-expected output from the regression tests,
it may indicate a bug in CVS (or might just indicate a problem
running the tests). If you choose to submit a bug report,
be aware that, as with all bug reports, you may or may not get a
response, and your odds might be better if you include enough information
to reproduce the bug, an analysis of what is going wrong (if you have
the time and ability to provide one), etc. The check.log file is the
first place to look.
4) Install the binaries/documentation:
$ make install
Depending on your installation's configuration, you may need to be
root to do this.
5) Take a look at the CVS documentation.
$ man cvs
and
$ info cvs
See what it 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...
6) Set up the master source repository. See the "Setting up the repository"
section of cvs.texinfo for details; the one-line summary is (if you
are putting the repository in /src/master):
$ cvs -d /src/master init
7) Have all users of the CVS system set the CVSROOT environment
variable appropriately to reflect the placement of your source
repository. If the above example is used, 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 sh/bash/ksh users, or place the following commands in the user's
~/.cshrc, ~/.login, or /etc/chsrc file:
setenv CVSROOT /src/master
for csh/tcsh users. If these environment variables are not already set
in your current shell, set them now (or source the login script you
just edited). You will need to have the CVSROOT environment variable
set to continue on to the next step.
8) It might be a good idea to jump right in and put the CVS distribution
directly under CVS control. From within the top-level directory of the
CVS distribution (the one that contains this README file) do the
following commands:
$ make distclean
$ cvs import -m 'CVS 1.6 distribution' cvs CVS_DIST CVS-1_6
9) Having done step 8, one should be able to checkout a fresh copy of the
CVS distribution and hack away at the sources with the following command:
$ cd
$ cvs checkout cvs
This will make the directory "cvs" in your current directory and
populate it with the appropriate CVS files and directories.
10) You may wish to customize the various administrative files, in particular
modules. See cvs.texinfo for details.
11) Read the NEWS file to see what's new.
12) Hack away.
-------------------------------------------------------------------------------
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.
-------------------------------------------------------------------------------
Installation under Windows NT:
You may find interesting information in windows-NT/README.
1) Using Microsoft Visual C++ version 2.1, open the project `cvsnt.mak',
in the top directory of the CVS distribution.
2) Choose "Build cvs.exe" from the "Project" menu.
3) MSVC will place the executable file cvs.exe in WinDebug, or whatever
your target directory is.
