apxs on MacOSX having trouble with architecture

I'm trying to set up a development environment on my aging Macbook Pro that matches my Linux EC2 production environment. I'm on the home stretch now, need only to get the mod_auth_mysql plugin for apache working. After a few hours of googling and patching and scratching my head, I think I'm almost there, but I've hit something that nothing I've found online has been able to solve.

nathan@ichigo:/usr/local/mod_auth_mysql-2.9.0$ sudo apxs -c -L/usr/local/mysql/lib -I/usr/local/mysql/include/ -lmysqlclient -lm -lz mod_auth_mysql.c 
/usr/share/apr-1/build-1/libtool --silent --mode=compile gcc    -DDARWIN -DSIGPROCMASK_SETS_THREAD_MASK -I/usr/local/include -I/usr/include/apache2  -I/usr/include/apr-1   -I/usr/include/apr-1  -I/usr/local/mysql/include/  -c -o mod_auth_mysql.lo mod_auth_mysql.c && touch mod_auth_mysql.slo
/usr/share/apr-1/build-1/libtool --silent --mode=link gcc -o mod_auth_mysql.la  -L/usr/local/mysql/lib -lmysqlclient -lm -lz -rpath /usr/libexec/apache2 -module -avoid-version    mod_auth_mysql.lo
ld: warning: in /usr/local/mysql/lib/libmysqlclient.dylib, file is not of required architecture
ld: warning: in /usr/local/mysql/lib/libz.a, file is not of required architecture
warning: no debug symbols in executable (-arch x86_64)

I thi开发者_Python百科nk this is complaining because it's trying to build for 64-bit, but I'm on a 32-bit platform? I'm not entirely sure. I've tried forcing a 32-bit build with env ARCHFLAGS and -D arch on apxs, to no avail.

FWIW, I also tried mod_auth_mysql-3.0.0, and hit more or less the same result.

Alternatively, is there a more modern way to auth against mysql in Apache? I didn't find anything else, but this module hasn't gotten any love in a good 5 years, and I had to apply some patches I found scattered about the 'net to even get this far.

First, check what architectures your libraries support with file /usr/local/mysql/lib/libmysqlclient.dylib, etc. Once you know that, I think you can control what apxs builds for by adding flags like -Wc,"-arch i386" -Wl,"-arch i386"
