-------------------------------------------------------------------------------
Now back to our regularly scheduled program:
Please read the README file before reading this INSTALL file. Then, to
install CVS:
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@nongnu.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.

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 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:

(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
(footnote 12)
Need to `configure --without-gssapi' unless you have installed Kerberos 5
libraries on the system yourself. For some reason Apple ships OS X with
the Kerberos 5 headers installed and not the libraries, which confuses the
current configure script. Some HP, BSD, & Sun boxes have similar problems.
(footnote 13)
A build under HP PA-RISC 2.0 will probably not run under PA-RISC 1.1
unless "+DAportable" is added to the HP ANSI cc compiler flags.
(footnote 14)
Because of the case-insensitive file system on Mac OS X, you cannot build
CVS directly from a checkout from CVS. The name of the built executable,
`cvs', conflicts with name of the CVS administration directory, `CVS'.
The work-around is to build the executable from a build directory separate
from the source directory. i.e.:
cvs co ccvs; cd ccvs
mkdir build; cd build
../configure && make
-------------------------------------------------------------------------------
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%.
If you are building CVS with the server enabled, you can disable
server flow control using the --disable-server-flow-control
If you are working with a large remote repository and a 'cvs
checkout' is swamping your network and memory, enable flow control.
You will end up with even less probability of a consistent checkout
(see Concurrency in cvs.texinfo), but CVS doesn't try to guarantee
that anyway. The master server process will monitor how far it is
getting behind, if it reaches the high water mark, it will signal
the child process to stop generating data when convenient (ie: no
locks are held, currently at the beginning of a new directory).
Once the buffer has drained sufficiently to reach the low water
mark, it will be signalled to start again. You may override the
default hi/low watermarks here too by passing
'<lowwater>,<highwater>', in bytes, as an argument to
--enable-server-flow-control. The low water mark defaults to one
megabyte and the high water mark defaults to two megabytes.
$ ./configure --enable-server-flow-control=1M,2M
The --with-tmpdir argument to configure may be used to set a
specific directory for use as a default temporary directory. If not
set, configure will pick the first directory it finds which it has
read, write, and execute permissions to from $TMPDIR, $TMP, $TEMP,
/tmp, and /var/tmp, in that order. Failing that, it will use /tmp.
The --with-umask argument to configure can be used to change
the default umask used by the CVS server executable.
Unlike previous versions of CVS, you do not need to install RCS
or GNU diff.
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.
If you want to disable automatic dependency tracking in the makefiles,
use the '--disable-dependency-tracking' option:
$ ./configure --disable-dependency-tracking
This avoids problems on some platforms. See the note at the end of this
file on BSD.
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 supply the --disable-cvs-ndbm option to configure to
accomplish this. 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) 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.
3) 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 run `./configure --help' or 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/95/98/2000:
You may find interesting information in windows-NT/README.
* Using Microsoft Visual C++ 5.x (this is currently broken - someone with
MVC++ 5.x needs to regenerate the project files, but the builds using `nmake'
below will work).
1) Using Microsoft Visual C++ 5.x, open the project `cvsnt.dsw',
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.
* From the top level directory, with MSVC++ 6.0 installed, something like the
following also works:
C:\> vcvars32
C:\> nmake /f cvsnt.mak CFG="cvsnt - Win32 Debug"
* Using the Cygwin development environment <http://cygwin.com>, Windows clients
and servers can be built using the instructions for building on UNIX. For
deploying the CVS server on Windows NT, see the `cygrunsrv' executable that
comes with Cygwin.
* You might also try <http://wincvs.org> & <http://www.cvsnt.org>.
-------------------------------------------------------------------------------
Building from source code under other platforms:
For OS/2, see os2/README and emx/README.
For VMS, see README.VMS
Mac OS X: Builds fine, just like UNIX.
For older versions of Mac OS, you might try <http://wincvs.org>.
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).
