I'm exchanging PMs with SRBOOTH to see if we can figure out why the ccminer binaries that I posted are not working for him.
@jwinterm, if I read correctly, you also had some trouble on Windows. In case you used the binaries that I had posted, do you recall what was the error on your end?
@smooth, awesome job on the pruning release! I've been happy solo mining, hitting at least one block per day, sometimes two. Need all the power we can have against nefarious Moooooooooo.

I'll see if I can build the pruning release and start testing that as well tonight.
The relevant file causing the problem was my cudart32_65.dll was not up to date for the 6.5 build even though I had installed cuda 7. Found this out after updating my driver. Then copy and pasted the updated cudart32_65.dll to the .bat file on another machine where the driver was not yet updated and ccminer worked fine without going through the update. Kinda good to know in the case of a driver rollback or other testing. So it looks like , at least in this case, a matching dll would would work for others who have not or do not want to fully update. This was related to the 750ti btw.
