<div dir="ltr">Thanks, I has found an reference to cuda-5.5 in the environment library path, so this should be the error. But now I get to the same point as with cuda 5.5.

Therefore, I would suspect that the error originates from your cuda setup. Notice e.g. that nvcc calls your c++ host-compiler in the background. -Ole</pre> Am Sonntag, 29.
