I know that this issue has been as been asked several times but no solutions works for me.
I installed cuda following the guide on a MacBook Pro 2010 and start the deviceQuery example and only get:
[./deviceQuery] starting... ./deviceQuery Starting... CUDA Device Query (Runtime API) version (CUDART static linking) cudaGetDeviceCount FAILED CUDA Driver and Runtime version may be mismatched. [deviceQuery] test results... FAILED
I’ve tested on Mac os x 10.6, 10.7 (dev preview 1 & 2) with Cuda 3.0, 3.1, 3.2 rc, 3.2, 4.0 rc, nothing works
The “trick” with gfxCardStatus also doesn’t work
I have no more ideas where the error is, maybe someone can help me.
I’ve read that on linux there are /dev/nv* devices and I don’t have any of this, is this a problem or normal on a mac?
