### Solaris 2.X

You must compile Kerberos V5 without the UCB compatibility libraries. This means that `/usr/ucblib` must not be in the LD_LIBRARY_PATH environment variable when you compile it. Alternatively you can use the `-i` option to `cc`, by using the specifying `CFLAGS=-i` option to `configure`.

If you are compiling for a 64-bit execution environment, you may need to configure with the option `CFLAGS="-D_XOPEN_SOURCE=500 -D__EXTENSIONS__"`. This is not well tested; at MIT we work primarily with the 32-bit execution environment.
