Problem: First of all, when compiling the created solution with VS2012 I get following error:

GL_PERSPECTIVE_CORRECTION_HINT not declared error when compiling

Although, it's stated in the end that it has something to do with OpenGl version when following this http://code.opencv.org/issues/3411 OpenCV will compile, both Debug and Release without error.

However, when using the CV_WINDOW_OPENGL flag for namedWindow

namedWindow(progName, CV_WINDOW_NORMAL | CV_WINDOW_KEEPRATIO | CV_GUI_EXPANDED | CV_WINDOW_OPENGL);

at runtime I get the error described in the topic:

init done
opengl support available
OpenCV Error: OpenGL API call (Can't load OpenGL extension [glBindBuffer]) in IntGetProcAddress, file sources\modules\core\src\gl_core_3_1.cpp, line 146

The same error occurs an a complete fresh Win7 install on a VirtualBox wit same Versions and settings as above.

I would really love to see OpenGL support working =)

Can somebody help? Kind regards, AR

Edit (Update: 01.05.2014): So I decided to try another Qt release, my setup was:

OS: Windows 7 64 bit with VS2010 (patched with SP1) as C++ compiler.
OpenCV: 2.4.9 (http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.9/opencv-2.4.9.exe/download)
Qt: 5.2.1 (http://download.qt-project.org/official_releases/qt/5.2/5.2.1/qt-opensource-windows-x86-msvc2010_opengl-5.2.1.exe)

Using the same CMake config I run into a first problem:

Failed to find "glu32" in "" with CMAKE_CXX_LIBRARY_ARCHITECTURE "".

Solution (thx @ https://qt-project.org/forums/viewthread/39501):

Add the following just beneath the line 'macro(_qt5gui_find_extra_libs Name Libs LibDir IncDirs)' in Qt5GuiConfigExtras.cmake:

set(CMAKE_LIBRARY_PATH "C:\\Program Files (x86)\\Microsoft SDKs\\Windows\\v7.0A\\Lib")

Afterwards CMake configures without errors and OpenCV debug/release compiles without errors.

However, when trying to use

CV_WINDOW_OPENGL

again same error occurs on runtime

OpenCV Error: OpenGL API call (Can't load OpenGL extension [glBindBuffer]) in IntGetProcAddress, file sources\modules\core\src\gl_core_3_1.cpp, line 146

Investigating further, I found a thread http://answers.opencv.org/question/25890/cannot-create-an-opengl-window/ which suggests that:

in fact you need OpenGl 3.0 or higher in order to use CV_WINDOW_OPENGL

which in case of my VirtualBox VMs kills the possibility of using it (there is currently only a OpenGL 2.1 available, use GPU Caps Viewer http://www.ozone3d.net/gpu_caps_viewer/ to find out your OpenGl Version for yourself)
