I installed OpenCV using the OpenCV_2_4_4.exe and the OpenCV-2.4.4-CUDA-vc10 and then placed these extracted files under C:\opencv. I also have CUDA4.2 installed on my system. I then tried running the sample program under C:\opencv\samples\alpha_comp.cpp and it crashes at line 19 -namedWindow("Result", WINDOW_OPENGL); giving the following error- OpenCV Error: No OpenGL support …

Feb 06, 2014 · That error message is displayed by OpenCV, so OpenCV is telling you it wasn't compiled with OpenGL support.

I am trying to build OpenCV 2.4.1 with OpenGL support, and it keeps faling. I have OpenGL installed in my Ubuntu 11.04, libs are under /usr/lib/libGL.so as usual.

Jul 10, 2018 · 1. JetPack 3.2 should only install cuda-9.0. If you get cuda8, there is a problem. I'd advise to download again JetPack3.2 and redo the install in a new folder (reusing an old JetPack folder may lead to problems). 2. The opencv-3.3.1 included in JetPack-3.2 has no gstreamer support and no CUDA support (and no OpenGL support). 3.
