I keep getting this error and can't get rid of it:

Linking CXX executable ../../bin/opencv_perf_core
../../lib/libopencv_core.so.2.4.2: undefined reference to `cuDeviceGetAttribute'

I have installed CUDA & CUDA SDK in my ubuntu 12.04 laptop and the cudalibrary and c examples are working perfectly. The problem comes when trying to compile OpenCV 2.4.2 with CUDA=ON.

Any ideas are welcome! Thank you.

I solve this problem by going to CMakeCache.txt after generating UNIX makefile using cmake-gui, in the directory you set to build the binaries, and adding the path for the "libcuda.so" to this line "CUDA_CUDA_LIBRARY:FILEPATH=" so in my case i ended up with "CUDA_CUDA_LIBRARY:FILEPATH=/usr/lib/nvidia-current-updates/libcuda.so"
