Ok, so here is another question/issue:
I'm trying to compile gnugb on Linux Mint.
Everything looks fine and no error messages. But when trying to run gnugb in a terminal, nothing happens. It hangs and uses 100% cpu on one core. It's possible to break it with Ctrl-C.
My system: Linux Mint 18.1 xfce 64 bit running on an AMD Athlon 5600+ dual core.
