I’m attempting to build MyPaint from the master branch, and installed all the needed dependencies as listed here.

MyPaint version: master branch

Operating System + Version: openSUSE Tumbleweed
KDE Plasma 5.9.4

This is the output I’m getting when running python setup.py demo:

Could someone tell me what’s happening? Am I missing anything?


#2

I’m pretty sure you are building against an older version of libmypaint. Get the newest libmypaint here

build and install that (instructions here), then build mypaint.

I think the instructions should be updated to include building libmypaint from src instead of fetching packages (that might be out of date). Generally those packages work but there was a recent update that requires changes to both mypaint and libmypaint.


#3

Thanks! It builds successfully now and everything seems to work. :slight_smile:
