I have installed 2x nvidia opencv however when I try to install libhighgui-dev, dependencies include: libopencv-core-dev libopencv-core2.4 libopencv-highgui-dev libopencv-highgui2.4 libopencv-imgproc-dev libopencv-imgproc2.4
its not clear to me: how to proceed?
ie are these already installed, but not found? or what?
Might it be helpful to add something more general around this type of issue? ie to clarify what type of issues to watch out for. and what is included... https://devtalk.nvidia.com/default/topic/778637/embedded-systems/libhighgui-dev-opencv-dependency-/
CUDA itself is functional, OpenCV-2.4.9.zip download as described here. But ccmake reports CUDA_CUDA_LIBRARY undefined, numpy not present, etc. (In default tegraK1 ubuntu out-of-box)
It sounds like you are trying to build OpenCV from source? If you do that, you can't get the hundreds of CPU optimizations (for quad-core and NEON SIMD) that OpenCV4Tegra prebuilt packages provide. So I recommend that you don't build OpenCV from source, I recommend you use the OpenCV4Tegra prebuilt packages, as mentioned above the manual installation section. OpenCV manual installation is mostly just for people modifying the OpenCV library (such as NVIDIA employees, since we have access to the OpenCV4Tegra source code including all our closed-source optimizations).
