My suspicion would be that /usr/lib/nvidia-current/libcuda.so.1 is not the current (3.2) version of libcuda.so. (But it seems you're compiling against 3.2 headers, which gives you unavailable symbol errors. You can easily check for a 3.2 libcuda yourself: I get: nm -D /usr/lib/libcuda.so | grep cuMemAllocPitch_v2 000000000015c0e0 T cuMemAllocPitch_v2 Try nm -D /usr/lib/nvidia-current/libcuda.so.1 | grep cuMemAllocPitch_v2 If you get empty output, you have an old version.
