[Gimp-developer] How to set the python path for GIMP plug-ins when bundling into an AppImage

[Carmelo DrRaw <aferrero1975 gmail com>]

Hi!

I am facing a problem when trying to build a GIMP AppImage that bundles python to allow running the 
python-based plug-ins.

As far as I understand, GIMP takes the python executable specified in 

    PREFIX/lib/gimp/2.0/interpreters/pygimp.interp

where the executable path has to be specified with an absolute way (otherwise GIMP throws an error “Bad 
binary format string in interpreter file …”).

However, in the AppImage case the absolute path into which the package is extracted is random, and is only 
known after the AppImage has ben actually started. Moreover, configuration files inside the AppImage bundle 
cannot be modified because they are read-only.

Hence my question: is there a way to dynamically specify the path to the python interpreter? In such 
situations one would typically use environment variables, but there seems to be no way in this case…


Thanks a lot in advance!
