### Build Requirements

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.
