Build OpenCV with CUDA support

Question

Im use CMake to generate visual studio 2013 solution. Next im try to build it, but get follow error:

Building NVCC (Device) object modules/core/CMakeFile

Answer 1

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_TIFF=ON -D BUILD_EXAMPLES=ON -D CUDA_GENERATION=Kepler -D BUILD_NEW_PYTHON_SUPPORT=ON ..

worked for me for OpenCV 2.4.11

Answer 2

This is because of your gpu type is mismatching.

You have to define CUDA_GENERATION explicitly.

In my side, I could find 3 types of CUDA_GENERATION; Auto, Kepler, Fermi.

When I set CUDA_GENERATION as Kepler, compute_11 changed to compute_30 and build successful.
