I was trying PHP5 1.4.10 and 1.5.6 RPMs for Linux Redhat Fedora Core
from rpm.pbone.net, then I tried to rebuild both PHP5 1.5.6 and HTTP
2.2.3 fresh from source on my machine... and still got the same problem.
I finally found the right set of build configure options to get around
this:
If I build PHP with ./configure --with-apxs2=/usr/local/apache2/bin/apxs
(like the example in the PHP INSTALL doc showing how to build to
integrate with Apache 2.0) then I get these ap_* undefined symbol
errors.
If I build PHP without the Apache 2.0 integration then the
tuscany_sca_php.so loads OK without the ap_* undefined symbol errors.
So I'm doing that for now, but what if I want to use PHP scripts in my
Apache 2.0 server now? am I just left with CGI integration?
