[rt-users] can't locate XXX

Wed Apr 20 14:50:41 EDT 2011

Ok bare with the long email!

Yes, I have a literal ... It's quite amazing how far you can get with an RT
setup based on wiki pages and rt-users listserv history without actually
knowing ANY Perl what so ever :D I have ExternalAuth and RT-FM setup as
other plugins... and all I did with those was follow step by step on the
wiki pages/READMEs.  For both, I copied and pasted the "Set" line for the
RT_SiteConfig.pm directly from there.  So being 100% honest, I never thought
of what it is or how it's works, just that the README or wiki told me it was
required.

Once Ruslan pointed to that line being a potential problem, I realized
RTFM wasn't ACTUALLY working... only the RTFM data was there, the
functionality wasn't working. I attempted to search for more information on
what that line is actually doing, but all I found was the wiki page
mentioned in the previous email. Which on that page specifically states you
can't have 2 @Plugin sets... that's why RTFM wasn't working...

Now with that knowledge, I understand my config line should read

Set(@Plugins,qw(
          RT::Authen::ExternalAuth
          RT:Extension::ExtractCustomFieldValues
));

The original information from Ruslan makes more sense now. I have corrected
that, and the new error is back to the Can't locate the .pm in @INC.

So now, what I believe that error is telling me is

 ...RT:Extension::ExtractCustomFieldValues

is an abstractual definition of where the ExtractCustomFieldValues.pm is
located within one of the paths of the @INC variable.

Taking the working ExternalAuth plugin string, which is
'RT::Authen::ExternalAuth', I understand that  RT::Authen equates to
RT/Authen and ExternalAuth is the .pm

That means, as long as @INC has the path before RT/Authen/ExternalAuth.pm
we're good!

What I don't understand now is how @INC gets
/opt/rt3/local/plugins/RT-Authen-ExternalAuth/lib

I could do a hack, and get it to work with the knowledge I have built now,
but I'm looking for the RIGHT way to do it.

How do I tell get /opt/rt3/local/plugins/ExtractCustomFieldValues in @INC?

And providing I can do the above, the way the tgz file untar's, the .pm file
is in that directory, so my Set @Plugins line would look like

Set(@Plugins,qw(CustomFieldValues RT:Authen:ExternalAuth));

Sorry for the long email, but I wanted to ensure my assumptions are correct
all the way through the troubleshooting logic I've used.

Thanks!
Mike.
