I'm unable to get cgminer working on a debian cpu only system. When I use the readme file's recommended configure line:
And it just stops. If I make install anyway, it doesn't want to work. Thanks in advance for any help!
try
CFLAGS="-O2" ./configure --enable-cpumining
works for BTC. Tried it on testnet (win64). You can use it for testing, but to make real coins you would have to be really lucky or live for a very long time.
Which bit of "cgminer doesn't support CPU mining" don't you understand?

CPU mining was removed ages ago. 2.11.4 doesn't even have it, and that's the oldest version I have here.
