Please comment with the output of `emerge --info` and attach the full build log. "Compilation issues with CUDA 5.5 will be fixed in 2.4 branch and in the next release (2.4.6). OpenCV 2.4.5 can be built only with CUDA 4.2 or 5.0." Please update to opencv-2.4.6.1 where this is fixed. PS. dependencies have been fixed in 2.4.5 |
If ones try to install media-libs/opencv-2.4.5 with >=dev-util/nvidia-cuda-toolkit-5.5 (currently ~arch) installed, you will experience the following cmake error: CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: CUDA_npp_LIBRARY (ADVANCED) linked by target "opencv_core" in directory /var/tmp/portage/media-libs/opencv-2.4.5/work/opencv-2.4.5/modules/core linked by target "opencv_gpu" in directory /var/tmp/portage/media-libs/opencv-2.4.5/work/opencv-2.4.5/modules/gpu linked by target "opencv_nonfree" in directory /var/tmp/portage/media-libs/opencv-2.4.5/work/opencv-2.4.5/modules/nonfree -- Configuring incomplete, errors occurred! According to the opencv guys the version is not compatible: http://answers.opencv.org/question/14326/problem-of-building-opencv-245-with-cuda-55-rc/ this incompatibility should be reflected in the ebuild, what is not the case: cuda? ( >=dev-util/nvidia-cuda-toolkit-4.2 )
