I use ubuntu, use following cmake options:
cmake .. -DBUILD_EXAMPLES:BOOL="1" -DBUILD_opencv_world:BOOL="1" -DWITH_TBB:BOOL="1" -DENABLE_FAST_MATH:BOOL="1" -DENABLE_AVX:BOOL="1" -DINSTALL_C_EXAMPLES:BOOL="1" -DCMAKE_INSTALL_PREFIX:STRING="/opt/opencv-cuda" -DCUDA_TOOLKIT_ROOT_DIR="/usr/local/cuda-5.5/" -DCUDA_FAST_MATH:BOOL="1" -DWITH_NVCUVID:BOOL="1" -DWITH_CUBLAS:BOOL="1" -DBUILD_DOCS:BOOL="1"
cuda-related output of cmake:
-- CUDA detected: 5.5

When I compile, however, I get the following errors:

Now, it compiles fine without CUDA (after a bit editing ffmpeg-related sources) but I cannot figure out what to do with this atomicAdd error. Help would be much appreciated.
P.S. 2.4.6.1 compiles fine but I kind of like using latest versions...
