Getting further. It appears if I add the path of the newly built json-c.pc to the environment variable it now asks for me to do the same for glib.

After doing so, I'm stuck here now:

(Build environment: yet another PC. This time my AMD Phenom II 1055T running Win8.1x64. Same version of MinGW that was suggested above.)

Looked up the error message : scons: warning: No version of Visual Studio compiler found - C/C++ compilers most likely not set correctly

Apparently it's exactly what the error is telling us. We need VS. And one forum post suggests that only 2012 will do. Downloading 2012 Express and crossing my fingers.

[edit] doing so eliminated the VS error but did nothing to help with the code attempting to delete from an array in env that doesn't exist.

Edited mypaint/lib/SConscript @ line 75:

# Make sure assertions are enabled
if env.get('CPPDEFINES'):
    try:
        env['CPPDEFINES'].remove('NDEBUG')
    except:
        print('NDEBUG was not enabled, not disabling.')

Then running the build produces the following output:

You don't want to install MSVC, honestly. MSYS2 is all about Open Source code generators, tools and libraries. I gave up on scons about ten years ago since it didn't even grok cross compilation, but AFAIR you need to tell scons to use mingw tools..
