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.
________________________________ From: Ircha, Andrew Sent: 09 October 2008 00:26 Subject: RE: Cannot start Apache with mod_perl 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). -----Original Message----- From: Fred Moyer Sent: Wed 10/8/2008 6:02 PM To: Ircha, Andrew Cc: modperl@perl.apache.org Subject: Re: Cannot start Apache with mod_perl ispyhumanfly wrote: > Ircha, Andrew wrote: >> I'm attempting to run httpd with mod_perl, but the httpd refuses to >> start: >> >> Starting httpd: httpd: Syntax error on line 209 of >> /etc/httpd/conf/httpd.conf: Syntax error on line 10 of >> /etc/httpd/conf.d/perl.conf: Cannot load /etc/httpd/modules/mod_perl.so >> into server: /etc/httpd/modules/mod_perl.so: undefined symbol: >> modperl_io_perlio_restore_stdout 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. >> There's a hint on this mailing list that mod_perl 2 and perl 5.10.0 >> don't work together, but I'd like to discuss this before going back to >> 5.8.8, as I don't know how to downgrade perl with yum. >> > I'm not expert in regards to this matter, however I run mod_perl2 and > Perl 5.10 just fine. So I'd be looking elsewhere for a solution...
