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. I know my OpenGL installation is correct because I have C++ OpenGL projects that compile, link and run OK. I run the cmake command as follows, because I want both CUDA and OpenGL support.

To enable OpenGL support, configure OpenCV using CMake with WITH_OPENGL=ON . Currently OpenGL is supported only with WIN32, GTK and Qt backends on Windows and Linux (MacOS and Android are not supported). For GTK backend gtkglext-1.0 library is required. Note that this is OpenCV 2.4.8 and this functionality has changed quite recently.

Hi guys, I built OpenCV libs with OpenGL support enabled in CMAKE. The build process went without problems. Then I could generate the install folder with include/bin/lib from vs2010. However, when I try to create an OpenGL windows like cv::namedWindow("ogl", cv::WINDOW_OPENGL). It still says library was built without OpenGL. Thanks for any help

Apr 18, 2019 · Hi all, I have been unable to build OpenCV from source with support for CUDA 10.1, OpenCL and OpenGL. This issue applies to both the 4.1.0 and 3.4.6 versions of OpenCV. There seems to be an issue with a sharing function between OpenCL and OpenGL namely clGetGLContextInfoKHR.

Feb 06, 2014 · On windows, I think you should download the OpenCV source and CMake to re-build the OpenCV library with ENABLE_OPENGL=ON flag. The pre-compiled version you have downloaded usually does not support OpenGL. I believe Chapter 3 has the instructions on how to build OpenCV with OpenGL support.
