Bugzilla Bug 20552

Gimp seems to fail to load perl plug-ins. I installed a selfmade ebuild
(gimp-gallery) for a perl plug-in but I could not find it anywhere in Gimp. If I
start gimp from the shell, it seems to me that the plug-in(s) fail due to a
problem with INC (path?).

Gimp: Latest version installed: 1.2.3-r3
Perl: Latest version installed: 5.8.0-r10

Do you have this problem with gimp-1.2.4 ?

Yes, with Gimp 1.2.4 (and HTML-Parser-3.28 instead of HTML-Parser-3.26-r2, both
no difference) the problem persists, though the shell output is greatly
reduced.


Identified problems
-------------------
"HTML/Entities.pm" is still not found though on my system it is here:
"/usr/lib/perl5/site_perl/5.8.0/i686-linux/HTML/Entities.pm"

"Gtk.pm" is still not found though on my system it is here:
"/usr/lib/perl5/site_perl/5.6.1/i686-linux/Gtk.pm"

I had contact with the author of Gimp-gallery who advised me to install
HTML:Entities too. I will post a note on my success regarding this.

I found HTML::Entities to be in the package HTML-Parser (at least I believe so:
http://search.cpan.org/author/GAAS/HTML-Parser-3.28/lib/HTML/Entities.pm).
However, I do not know whether this is a genuine Perl problem or whether the
Gimp package ought to be improved.

Considering it again, my best guess is, assuming @INC being somekind of a path
variable, @INC ought to include also
"/usr/lib/perl5/site_perl/5.8.0/i686-linux/HTML" and
"/usr/lib/perl5/site_perl/5.6.1/i686-linux/Gtk.pm"

hmm if #10 is true then this is perl problem, not gimp. I don't think gimp
misses anything, cause all gimps own plugins seem to work. Additional stuff
should be introduced by additional plugins. 

I'm not at all into perl, so i think its better to give this back to some perl
guy.

It looks like there are two different problems. First, that the gimp ebuild is
not depending on all that it needs to in order to enable perl support - that's
easy enough to fix if it is the case. The second problem is that the perl gtk
modules were installed prior to your upgrade to 5.8 - and don't appear to be
getting pulled in. I would recommend re-emerging the gtk module to get rid of
that error.

After "emerge gtk-perl" I only get a "Undefined subroutine &Gimp::Fu::register
called at /usr/lib/gimp/1.2/plug-ins/gallery.pl line 129.

LibGimp-WARNING **: gimp: wire_read: unexpected EOF" when starting Gimp. I
shall ask the developer of gimp-gallery about the message.

It's been some time since this bug received any attention. A new version of
gimp, perl and gtk-perl has been released in the mean time.

Please reopen this bug if it can still be reproduced.

Having installed gimp 1.2.5, perl 5.8.3 and gtk-perl 0.7008-r10 the gimp
plug-in in question gets loaded. I have not tested if the plug-in works though.
Thanks.
