Introduction to CVS

CVS is the Concurrent Versions System. This is a version control system useful for projects using a central repository to hold files and then track all changes made to those files. These instructions install the client used to manipulate the repository, creation of a repository is covered at Running a CVS Server.

CVS Dependencies


GDBM-1.8.3, Tcsh-6.14.00, krb4, MIT krb5-1.4.1 or Heimdal-0.7 (for the GSSAPI libraries), AFPL Ghostscript-8.51 or ESP Ghostscript-7.07.1, and an MTA

Installation of CVS

By default CVS is statically linked against the Zlib library included in its source tree. This makes it exposed to possible security vulnerabilities in that library. If you want to modify CVS to use the newest system shared Zlib library, apply the following patch:

patch -Np1 -i ../cvs-1.11.20-zlib-1.patch

Install CVS by running the following commands:

./configure --prefix=/usr &&

To test the results, issue: make check.

Now, as the root user:

make install &&
install -v -m755 -d /usr/share/doc/cvs-1.11.20 &&
install -v -m644 doc/cvs{,client}.ps /usr/share/doc/cvs-1.11.20

Configuring CVS

Config Files

~/.cvsrc, ~/.cvswrappers, and ~/.cvspass.

Configuration Information

~/.cvsrc is the main CVS configuration file. This file is used by users to specify defaults for different cvs commands. For example, to make all cvs diff commands run with -u, a user would add diff -u to their .cvsrc file.

~/.cvswrappers specifies wrappers to be used in addition to those specified in the CVSROOT/cvswrappers file in the repository.

~/.cvspass can hold passwords to complete logins to servers.


Installed Programs: cvs, cvsbug, and rcs2log
Installed Libraries: None
