I finally resolved the problem I was having with mod_auth_mysql. I was less
than impressed with the lack of response from any quarter about the problem,
but I continued to see what I could find. It comes down to something being
broken in libmysqlclient.a.
Using the RPMs for devel and client for 3.21.32a from tcx, I was able to
build a mod_auth_mysql without needing to include -lgcc. This loaded up into
apache, accessed the database, authenticated users and allowed mod_perl to
continue to function.
Using 3.22.8-beta, I got a failure to load the mod_auth_mysql because of a
missing 'lstat'. I don't understand this, but it's not relevant other than I
wasn't able to track down which specific version of libmysqlclient starts
Using 3.22.16 -> 3.22.20 I have to include -lgcc to get the thing to link
and load into the server. However, once it's loaded it screws up Apache to the
point that calls to mod_perl cause the server to segfault within libperl.a.
The reason that -lgcc needs to be specified is that '__ucmpdi2' comes up as an
undefined symbol without it.
I don't know where in the libmysqlclient.a code that is referenced, or what
is referenced in the lib that references something that contains that little
gem, but once you compile mod_auth_mysql it appears.
RedHat 5.1, glibc-2.0.7, apache-1.3.4, gcc 220.127.116.11.
