I'm not familiar with 'scons' and 'swig', so I think I'll drop this package to AUR.

There is a swig3 package, you could use that for now
Comment by Balló György (City-busz) - Thursday, 29 August 2019, 12:20 GMT
I don't know how to force the build system to use swig3 instead of swig.

Maybe it would be worth packaging this alpha instead? https://github.com/mypaint/mypaint/releases/tag/v2.0.0-alpha.12

Discussion: https://github.com/mypaint/mypaint/issues/929

It drops the use of scons and adds support for depending on the system libmypaint package. Generally alphas of software would be avoided if possible, but given mypaint doesn't build at the moment, it might be better than dropping it to the AUR.

I discovered what this mypaintlib.py is doing differently and submitted https://github.com/mypaint/mypaint/issues/1030 about the breakage.

@eschwartz: Thanks for investigating this. I still have no idea how we can solve this problem, so I'm reassigning this task to you.

Raising severity now that a broken package has been pushed to the repos
Comment by Antonio Rojas (arojas) - Saturday, 07 September 2019, 09:11 GMT
Pushed a package that uses swig3 as a hotfix for the current broken package. There seems to be some movement in the upstream report towards making it work with 4, so hopefully this can be properly fixed soon.
Comment by Eli Schwartz (eschwartz) - Thursday, 12 September 2019, 00:49 GMT
I backported their swig 4 patch. All seems to be well. Some files did move from /usr/share/mypaint to /usr/lib/mypaint, but hopefully that is well too.
