FWIW, here is how I build babl/GEGL/GIMP from git:
What prefix are you installing babl/GEGL/GIMP from git in?

I have my own ebuilds and they install into /usr

One thing that sometimes helps is to completely uninstall all versions
of babl/GEGL/GIMP (even the portage versions). Then in the prefix for
babl/GEGL/GIMP from git, delete and recreate the install folder, so
there's nothing left behind to interfere with a fresh install. And also
do "git clean -xdf" to get the build folders completely clean. And then
start installing from scratch.

I've done that but the problem persists

The only other thing that comes to mind is whether your libraries for
jpeg, png, and tiff are all too old.

I have media-libs/libjpeg-turbo-1.5.1

Just for reference, here's what I have:


I'm not sure whether GIMP uses lib-jpeg-turbo or openjpeg. But maybe installing openjpeg would help.

As we both have the same version of tiff installed, outdated libraries probably aren't the only problem, or else you would be able to export a tiff.

Your libpng is too old - I'm a bit surprised that recently pulled GIMP-2.9 builds at all given the older version of libpng.

Do you have a hint on how to debug my problem?

Any problem that results specifically from an ebuild, no, I'm clueless. You could try building in a prefix as per my "how to build" article and see if you still have a problem exporting files.

Did you try using the "--enable-debug=yes" option when running, and then running GIMP under gdb?

I saw your stack trace but it didn't seem helpful, well, imho they often aren't. Beyond that, no, my apologies, I'm not very experienced at debugging code.

Oh, wait, looking at your stack trace again, it seems a bit odd that there is all this stuff about tiff when you are trying to output a jpeg. I've seen problems where there is interference between a GIMP plug-in for opening a raw file and the GIMP code for opening a tiff (
