Markdown or CGI error prevents web-based editing
I have a working ikiwiki configuration with an SVN backend, running on Ubuntu 7.10, Apache 2.2.4. I'm using Perl 5.8.8, however, I had to use Text::Markdown 1.0.5 from CPAN instead of the latest because I had the same issue as someone here (Namely I was getting this error until I used the old Markdown version: "*** glibc detected *** double free or corruption (!prev): 0x0922e478 ***
").

aside: that might have been related to Text::Markdown bug #37297.

CGI seems to be working at least partly - the History and Recent Changes pages both work. However, if I attempt to edit or create a page, I get this error:
Error: Failed to load plugin IkiWiki::Plugin::mdwn: Can't locate IkiWiki/Plugin/mdwn.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.8.8 /usr/local/share/perl/5.8.8 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.8 /usr/share/perl/5.8 /usr/local/lib/site_perl .) at (eval 6) line 2. BEGIN failed--compilation aborted at (eval 6) line 2.
Since ikiwiki builds, it has to be finding Markdown at build time, right? What am I doing wrong here? I would appreciate a point in the right direction. Thanks. --mrled

Ikiwiki is failing to find IkiWiki/Plugin/mdwn.pm which is a plugin included in ikiwiki itself.
So, that file must not have been installed in any of the directories in the @INC search path listed.
Either fix the installation so ikiwiki's perl modules are installed in one of the standard locations,
or you could use the libdir setting in the setup file to point ikiwiki
at the directory the perl modules are installed. --[[Joey]]


Ah hah! That helped... once I knew that it was ikiwiki's internal thing, I was able to figure out that it was a permissions issue. For the record, I didn't change permissions or the default install prefix of /usr/local (well, at least not on purpose). Thanks for your help. --mrled


Interesting.. so just a permissions problem of some sort that prevented the cgi from seeing the modules that were there in-path? --[[Joey]]
