/usr/bin/ld: i386:x86-64 architecture of input file `libckpool.a(sha256_sse4.A)' is incompatible with i386 output
Might be an intel 64 bit machine but it looks like you're trying to compile it for a 32 bit userspace. Ckpool is 64 bit only.
I'm relatively new to Linux. Is there a way I can direct it to compile as 64 bit? I just assumed it would do that somehow on its own.
By the way, I've been using your cgminer on another machine and it's been rock solid for a couple years. Nice work.
It just means you've installed a 32 bit linux distribution. Make sure to use a 64 bit one. There is no reason to use 32 bit any more anywhere.
