Thanks, lifeboat! I was able to use this on my 6950 after downgrading to catalyst 12.10 mentioned a couple of posts up.
Is there any chance you can build oclvanityminer64 as well? I'd be happy to donate some of the profits if I ever find any!
I thought I had managed to build it, and ended up with a (32bit) binary, but it just wouldn't run (Windows error saying "The application was unable to start correctly (0xc000007b). Click OK to close the application"). I had some issues building libcurl, I think that's where it went wrong. The readme doesn't mention it and it's just assumed in the makefile... I haven't dabbled in that area of programming in a number years, so I could be forgetting something pretty simple.
Or if you didn't want to build it for me but have an idea what I'm doing wrong, I'd happily accept some advice!
