RE: Cannot start Apache with mod_perl

["Ircha, Andrew" <An...@fkilogistex.com>]

Coming back to this, I used yum to update from mod_perl 2.0.4-6 to
2.0.4-7 and I was able to restart httpd (Apache). Haven't done any more
testing, but this is an encouraging start.

Thanks for the suggestion. Errant symbols implied a build on the server
might be an idea.

Sad to say I tried downloading the sources and running 'perl
Makefile.PL' etc before posting my message. Yes, I navigated to
/etc/httpd/modules to look at mod_perl.so to check the file modification
time.

I downloaded the .gz.tar archive from the mod_perl website.

Thanks again, but no dice.

Actually there's a funny story about this. Makefile.PL didn't work
because my perl 5.10 installation didn't have the necessary make stuff.
I couldn't get the necessary stuff because CPAN.pm wasn't installed. I
figured that perl wasn't correctly installed. So, I yum remove perl.
Ouch!! This uninstalled about 300 packages totalling some 200+ MBytes. I
then spend most of the remainder of the evening re-installing and
ftp'ing the missing guts of my system. (This shows just how naive I am).

My gut says that you have some of the original FC8 libraries hanging
around - if you are running 5.10.0 then your fedora install must have
upgraded at some point.  Those undefined symbol errors usually indicate
version mismatches of the underlying libraries.

For what it is worth, I would 'rpm -e mod_perl', then try building it
from source.  Just download 2.0.4, untar it, cd into the directory, and
run 'perl Makefile.PL && make && make test && sudo make install', apxs
should be in your PATH with the standard fedora setup.
