I found a "apache2-devel" RPM that installed apxs2 in /usr/sbin/apaxs2. For proof, here is the output: Code: [root@server native]# /usr/sbin/apxs2 Usage: apxs -g [-S <var>=<val>] -n <modname> apxs -q [-S <var>=<val>] <query> ... apxs -c [-S <var>=<val>] [-o <dsofile>] [-D <name>[=<value>]] [-I <incdir>] [-L <libdir>] [-l <libname>] [-Wc,<flags>] [-Wl,<flags>] [-p] <files> ... apxs -i [-S <var>=<val>] [-a] [-A] [-n <modname>] <dsofile> ... apxs -e [-S <var>=<val>] [-a] [-A] [-n <modname>] <dsofile> ... Now, I run the following: Code: ./configure --with-apxs=/usr/sbin/apxs2 and at the end I get this: Code: need to check for Perl first, apxs depends on it... checking for perl... /usr/bin/perl could not find /usr/sbin/apxs2 configure: error: You must specify a valid --with-apxs path I obviously just supplied it with the correct path. Why isn't it working?
