• Package name: SDL2_gfx
• Version: v1.0.3

@staticfloat please review and merge.

Looks like they're expecting only x86 architectures. I'm on it.

Should now work for ARM architectures, still need to fix some problems on PowerPC and FreeBSD

Thanks! There seem to be some linker errors on windows that I also do not understand.

I have the feeling that the remaining issues are all related to the very old build system of the package. If only we were able to rebuild the configure script...

Edit: well, there was a missing line in configure.in... 🙄

I didn't want to spend more time on investigating the problem and since this is very simple I just went with manually building the shared library out of the static archive.

For the record, most of the issues we found here are similar to what we had in #123. Also for Windows, the link problem is the same as the one reported in #123 (comment), and also the solution was the same: manually build the shared library.
