Thanks for trying to compile it on this platform.

It sounds like your toolchain is not properly setup. I'd love to make this code compile properly on raspberry pis, as they're a good fit there. Please PM me and I can try to fix this up. In the mean time and if you have gcc installed, you can try editing the file 'Makefile' and change the first instance of 'clang' with 'gcc', then comment out lines #12 and #13. Cheers.
