Since I update my machine to snow leopard, no supported device is found by CUDA.
I reinstall (twice) the drivers 2.3.0 twice as well as the SDK but still nothing.
I followed this instructions: [post=“0”]Instructions for making CUDA 2.3 work on Snow Leopard, How to fix permissions and nvcc linker errors[/post]
I have tried 3.0.1_beta driver, Toolkit and SDK on my 10.6.2 Snow Leopard.
SDK compiles successful without any changes of common.mk and links to gcc-4.0 $ g+±4.0
Xcode 3.2.1 must be installed.
But now deviceQuery returns that I have no supporting CUDA devices.
And deviceQueryDrv returns “Cuda driver error 3 in file ‘deviceQueryDrv.cpp’ in line 42.”
EDIT: Now it all works. I needed only launch in 32 bit mode and reinstall toolkit, driver and recompile SDK.
