问题描述
我正在尝试构建支持 OpenGL 的 OpenCV 2.4.1，但它一直在失败.我在 Ubuntu 11.04 中安装了 OpenGL，库像往常一样位于/usr/lib/libGL.so 下.我知道我的 OpenGL 安装是正确的，因为我有编译、链接和运行正常的 C++ OpenGL 项目.
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.
我运行 cmake 命令如下，因为我想要 CUDA 和 OpenGL 支持.
I run the cmake command as follows, because I want both CUDA and OpenGL support.
/data/OpenCV-2.4.1/build $ cmake -D WITH_OPENGL=ON -D CMAKE_BUILD_TYPE=RELEASE -D WITH_CUDA=ON -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda/ -D BUILD_EXAMPLES=ON -D WITH_TBB=ON ..
这是我从中得到的输出，告诉我 CUDA 被正确检测到，但 OpenGL 没有
This is the output I get from this, telling me CUDA was properly detected, but OpenGL wasn't

猜猜缺少什么?
推荐答案
您可能忘记安装 GTK+ OpenGL 扩展 和它们的标题
You probably forgot to install the GTK+ OpenGL Extensions and their headers
sudo apt-get install libgtkglext1 libgtkglext1-dev
