RTIR - Installation Issue - YAML.pm path missing in @INC at Apache Startup

Hi all,

Briefly - This post asks for help with an installation issue with RTIR 2.4.1.

I have a:
CentOS 5.3 server with…

RT v 3.8.2 installed, configured and working
RTFM v 2.4.1 installed, configured and working
RTIR v 2.4.1 (“perl Makefile.PL” reports all ok - “make install” succeeds)

When I enable the RT:IR plugin in RT_SiteConfig.pm - apache fails to start with the following error:

[Mon May 11 11:15:27 2009] [error] Can’t locate YAML.pm in @INC (@INC contains: /opt/rt3/bin/…/local/lib /opt/rt3/local/plugins/RT-FM/lib /opt/rt3/local/plugins/RT-IR/lib /opt/rt3/bin/…/lib /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.7/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.6/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl/5.8.7 /usr/lib/perl5/site_perl/5.8.6 /usr/lib/perl5/site_perl/5.8.5 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.7/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.6/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.5/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl/5.8.7 /usr/lib/perl5/vendor_perl/5.8.6 /usr/lib/perl5/vendor_perl/5.8.5 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 . /etc/httpd) at /opt/rt3/local/plugins/RT-IR/lib/RT/IR.pm line 437.\nBEGIN failed–compilation aborted at /opt/rt3/local/plugins/RT-IR/lib/RT/IR.pm line 437.\nCompilation failed in require at /opt/rt3/bin/…/lib/RT.pm line 625.\nCompilation failed in require at (eval 2) line 1.\n

I’ve found nothing similar in searching the list archives, the wiki, or even Google.

YAML.pm is present on my system at the following locations:

[root@itsec usr]# cd /usr/lib/perl5
[root@itsec perl5]# find . -name YAML.pm
./site_perl/5.8.8/Module/Build/YAML.pm
./site_perl/5.8.8/Test/YAML.pm
./vendor_perl/5.8.8/Locale/Maketext/Extract/Plugin/YAML.pm
./vendor_perl/5.8.8/Module/Build/YAML.pm

As apache reports, none of those paths appear in @INC at apache startup time.

***** Looking at the code: *****

Line 625 of RT.pm is in subroutine InitPlugins.

However, if we back up a step and look at line 437 of RT.pm, we see that it’s doing a “use:YAML;” right before making an attempt to log a critical error message that says “$self is not a ticket object like I expected”… it seems that had things been proceeding normally, $self WOULD have been a ticket object and we wouldn’t have taken the “else” branch in this code.

I’m not a perl guy, I’m a poor SysAdmin with a little programming experience. I’m hoping someone will take pity on me and offer some advice as to what the next step might be to try to resolve this problem. :slight_smile:

Thanks in advance!

Either install YAML perl module using the cpan shell or in
lib/RT/IR.pm replace the following two lines

        use YAML;
        $RT::Logger->crit( "$self is not a ticket object like I expected"
                . YAML::Dump($self) );

with

        $RT::Logger->crit( "$self is not a ticket object like I expected");

Will be fixed in RTIR 2.4.2On Mon, May 11, 2009 at 9:25 PM, Timothy M. Pearson tpearson@ois.pittstate.edu wrote:
