Description Hin-Tak Leung 2016-01-12 17:10:20 UTC
I am trying to use mkbundle to build native mac os x executables; mostly it works, except in the winforms layer, when I try to bundle/relocate libgdiplus, it is not happy about __cg_jpeg_resync_to_restart, which is available in the core.graphics version of libjpeg but not in the private version of libjpeg.

And the two version of libjpeg have different version/compatibility numbers (from otool -L) and not interchangable.

I assume there will be similar problem with the other libraries provided by both core.graphics and bundled with mono which libgdiplus depends on. (libtiff, libpng, etc?)

I think libgdiplus should statically link against its own copy of libjpeg if that's intentional, or linked against
core.graphics's libjpeg if jpeg facility is needed.
