Re my problem with Apache dying when I try and load the PHP module, it was
suggested to me that I should run strace on Apache when it is and isn't
trying to load PHP. Thanks to John Holden for the suggestion
Well....
To keep the trace relatively simple, I actually did a ktrace (it's 'ktrace' on
OpenBSD, not 'strace') when just asking apache to do a syntax check. The
syntax check fails when I include the 'LoadModule libphp4.so' line.
So, the command line was:
ktrace httpd -t
To compare like with like, I ran this with the 'LoadModule access_module' and
then again with 'LoadModule php4_module'.
This is what I got. When asked to load the PHP module, apache seems to then go and
search /usr/lib and /usr/local/lib. I'm assuming it's trying to resolve some
dependencies arrising from the PHP module, but I have no idea what they might be. Am I
missing some obvious dependencies ? What could apache be looking for ?
regards,
Rich.
