Cannot compile with -O2 optimizations #15

Closed vlapse closed 10 years ago

Hi.

I cannot compile newest ccminer with -O2 or -O3 optimizations....

remove the compute_20,code=sm,compute_20 part

I wonder how it got in there in the first place as ccMiner does not and will not support Compute 2.0 devices at this point.

if you look at Makefile.am in the current github master branch you won't find any mention of Compute 2.0

https://github.com/cbuchner1/ccminer/blob/master/Makefile.am

did you run ./autogen.sh also?

I didn't run ./autogen.sh, my fault sorry...
