Ok, so after doing some more reading it appears that you can simply build the mod_jserv.so module with a command like this: apxs -c mod_jserv.c -o mod_jserv.so However when I run the command I get another error: [root at pstest-app13 c]# /usr/sbin/apxs -c mod_jserv.c -o mod_jserv.so /usr/bin/libtool --silent --mode=compile gcc -prefer-pic -O2 -g -pipe -march=i386 -mcpu=i686 -DSSL_EXPERIMENTAL_ENGINE -I/usr/kerberos/include -DAP_HAVE_DESIGNATED_INITIALIZER -DLINUX=2 -D_REENTRANT -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -D_SVID_SOURCE -D_GNU_SOURCE -pthread -I/usr/include/httpd -c -o mod_jserv.lo mod_jserv.c && touch mod_jserv.slo mod_jserv.c:63:19: jserv.h: No such file or directory I think I'm getting closer to building mod_jserv.so, but this really is feeling like a wild goose chase. We try as much as possible to stick with RPM/yum for our package management but unfortunately the previous sysadmin liked to build a lot from source. Can someone help? Where do I find this jserv.h, and how do I tell apxs where it lives?
