I'm trying to build a patch to mod_auth_cas to allow regular expression matching in Apache Require directives. The code works, but I can't get the tests to compile. When I run "make check" I get errors that there's undefined references to ap_regcomp and ap_regexec. Could anyone let me know where I've gone wrong and point me in the right direction? This is a 64-bit RHEL6 system.
