Building Kerberos V5¶
This section details how to build and install MIT Kerberos software from the source.
Prerequisites¶
In order to build Kerberos V5, you will need approximately 60-70 megabytes of disk space. The exact amount will vary depending on the platform and whether the distribution is compiled with debugging symbol tables or not.
Your C compiler must conform to ANSI C (ISO/IEC 9899:1990, “c89”). Some operating systems do not have an ANSI C compiler, or their default compiler requires extra command-line options to enable ANSI C conformance.
If you wish to keep a separate build tree, which contains the compiled *.o file and executables, separate from your source tree, you will need a make program which supports VPATH, or you will need to use a tool such as lndir to produce a symbolic link tree for your build tree.
Obtaining the software¶
The source code can be obtained from MIT Kerberos Distribution page, at http://web.mit.edu/kerberos/dist/index.html. The MIT Kerberos distribution comes in an archive file, generally named krb5-VERSION-signed.tar, where VERSION is a placeholder for the major and minor versions of MIT Kerberos. (For example, MIT Kerberos 1.9 has major version “1” and minor version “9”.)
The krb5-VERSION-signed.tar contains a compressed tar file consisting of the sources for all of Kerberos (generally named krb5-VERSION.tar.gz) and a PGP signature file for this source tree (generally named krb5-VERSION.tar.gz.asc). MIT highly recommends that you verify the integrity of the source code using this signature, e.g., by running:
tar xf krb5-VERSION-signed.tar
gpg --verify krb5-VERSION.tar.gz.asc
Unpack krb5-VERSION.tar.gz in some directory. In this section we will assume that you have chosen the top directory of the distribution the directory /u1/krb5-VERSION.
Review the README file for the license, copyright and other sprecific to the distribution information.
