Does GIMP 2.10 find third-party plugins installed for 2.8?
It seems like it does not in my case: Ubuntu 17.10, I installed GIMP 2.10 from the official flatpak install, and installed the distribution package gimp-plugin-registry.
I saw that the location of plugins has changed in 2.10 (to something like ~/.var/app…). I did not see that documented in the GIMP 2.10 release notes. Anyway, in GIMP 2.10, I changed Edit>Preferences>Folders>Plugins and added paths to the old locations (something like /usr/local/lib/gimp/2.0/plug-ins, which is unique to Ubuntu?) and restarted GIMP, but it still did not seem to find the plugins I expected (specifically, resynthesizer set of .py plugins.)
I also built resynthesizer from source and installed it. Still GIMP 2.10 failed to find it. I suspect the build scripts need to be updated to the new install locations for GIMP plugins. But shouldn’t my changes to the preferences mean 2.10 would find the plugins for earlier versions of GIMP? Maybe I made a silly mistake.
Also, anyone have notes on building plugins for 2.10 using the old automake scripts for the gimp plugin template, e.g. do I need a new libgimp2.0 as well as changing the scripts to define a new install location?
