The problem seems to be an arch/platform dependent bug in the old ffmpeg code that is included in the distribution. It builds OK for me on 10.4.11 ppc.

Although this code is old, this version of gimp-gap is written specifically to it so the only thing to do is report the bug upstream and wait for a patch or new release. gimp-gap does not support external ffmpeg libraries (such as port ffmpeg) in this version.

To get around this, I have updated the port to disable this ffmpeg code by default at the expense of fewer supported video formats. To restore the ffmpeg code (which will continue to break for some) the +libavformat variant can be used.

This should allow you to proceed for now. Committed in r43011.

I get this exact same error after I used sudo port upgrade installed on my system. Has this been properly resolved, or is there something else I should do to get round it?

[dbevans (David B. Evans)]

The offending code was disabled by default in r43011 as shown above but was re-enabled later because it really couldn't do anything without it.

The best alternative is to install gimp-gap-devel which incorporates a much newer version of ffmpeg and has more functionality and better integration with the gimp 2.6 branch. This version is a pre-2.6 release version which will replace the existing gimp-gap version shortly. Just deactivate gimp-gap first and install gimp-gap-devel

sudo port deactivate gimp-gap
sudo port install gimp-gap-devel

[dbevans (David B. Evans)]

In r50716, updated gimp-gap-devel to svn 833 which incorporates latest ffmpeg 0.5 release snapshot. This should build well for all platforms. If not, please submit a new ticket with full details.

In r50718, fixed gimp-gap to abort with error message if attempting to install/upgrade on an i386 platform. Message suggests installing gimp-gap-devel instead.

Will update gimp-gap to version 2.6.0 when it is released (should be soon now.) In the meantime, gimp-gap-devel is a recent development snapshot from svn trunk.

Please be sure to resync your ports tree before trying to reinstall/upgrade to make sure you have the latest version of these ports.
