Well, the topic is self-explanatory. I’d give details, but I’m not sure what details might be relevant. This is with default GIMP 2.9 updated to a few days ago, and with PhotoFlow and the PhotoFlow plug-in updated to this morning. The same problem obtained with PhotoFlow and the plug-in from last week.
A couple of months ago everything worked, at least in my “CCE” version of GIMP - at that point I didn’t have PhotoFlow installed in the prefix for default GIMP. But now I can’t use PhotoFlow with default GIMP or with CCE.
When run as a standalone, PhotoFlow works just fine. It just doesn’t work as a plug-in.
This is on Gentoo Linux. The other GIMP 2.9 raw plug-ins work with no problem.
