Problems with mod_security on CentOS 64
Posted by TheMatrix, 06-28-2008, 11:41 PM Hello- I've been having the hardest time getting mod_security on my new CentOS 5.2 64-bit box. Everything is a straight, simple, standard install - nothing special or custom. Plesk and all the apps that come with it installed fine, everything was going great. Then I tried to compile mod_sec, and things have been nothing but problems. I think I've finally sorted out the problems with the compiler, but now I get this error: /usr/bin/ld: warning: i386 architecture of input file `.libs/msc_lua.o' is incompatible with i386:x86-64 output Repeated, for every file it tries to link. I've been googling and trying things for hours, and I just don't know what else to do. Thanks. -TM

Posted by TheMatrix, 06-29-2008, 05:16 AM I finally figured it out. x64 installations of apache (or at least CentOS 5.2 + Plesk) put their modules in /usr/lib64/httpd/modules - unfortunately mod_sec doesn't know that, and tries to link the objects using -rpath /usr/lib/httpd/modules, which doesn't exist. The solution is to make a link between /usr/lib/httpd/modules and /usr/lib64/httpd/modules to make it happy. I'm shocked that I'm the first person who has mentioned this anywhere.

Posted by TheMatrix, 06-29-2008, 05:29 AM Also, for those who may not know, you'll need the 64 bit version of libxml2.so. This is usually located in lib64 instead of lib. So instead of: LoadFile /usr/lib/libxml2.so You'll need: LoadFile /usr/lib64/libxml2.so
