make[2]: *** [cgminer] Error 1
This is a Mac running Snow Leopard booted in 64-bit mode. I found someone seems to have worked around it by using yasm -f macho64 and a patched assembly sha256 implementation from here:
https://github.com/jgarzik/cpuminer/issues/31
But I couldn't get this to work for me. Has anyone been able to compile cgminer on 64-bit Mac OS X systems? If you have a 2009 mac with relatively up-to-date software, you can enable 64-bit mode by typing:
Code:
sudo systemsetup -setkernelbootarchitecture x86_64
