A perfectly working perl module with the Gimp 1.2.3 now, with the Gimp 2.0.2 and the CPAN Gimp 2.0 stuff, stops during the execution saying:

Subroutine Gimp::gimp_undo_push_group_start redefined at /usr/lib/perl/5.8/Gimp.pm line 603.

What does it mean and what should I do?

Hi,

A small number of calls (some of them frequently used) have changed between versions; you might want to look at the ChangeLog for others.

Figuring out the changes from reading the ChangeLog is probably quite tedious. Actually we are still looking for a volunteer to write the "How to port your GIMP 1.2 plug-in/script to the GIMP 2.0 API" chapter for the developer documentation. Until that has happened, it is probably best to consult the API docs (distributed with the GIMP tarball and online at http://developer.gimp.org/api/2.0/).

Most changes are also listed in the compatibility header gimpcompat.h. This file is meant to be temporarily included while porting a C plug-in but it should also help you when porting a perl script.

Seth,

Many thanks for your quick reply. Now it all works fine!

Unfortunately for me the ChangeLog file wasn't that clear. But now, at last, I know how to use it! Thanks again.

Now, the perl module I have just fixed (called "join2pics", labels are in Italian) with your help combines two picture into one. In a nutshell, if you want to print on a A4 sheet four pictures ( as I often do with my digital camer's photos) you just call twice join2pics combining the picture you like either horizontally or vertically.
I think this module, translated into English, could be helpful to other people. How could I contribute it to other "GIMPers"?

Happy GIMPing to you

Vittorio
