Guess what guys? I just compiled Code::Block 16.01 on macOS Sierra! I am most willing to contribute to this project. Some things to note:
Makefile.in,Makefile.am,and aclocal.in are NOT NEEDED, otherwise it throws error about automakers not being found, although you don't need it anyway.
All I'm using to compile is:
HomeBrew with wxwidgets installed (plus a whole bunch of other, un-related things)
Xcode Command-Line Utils
Might try to post a working binary eventually. I'll keep things updated here.
