Hi

i'm trying to compile OpenCV 2.4.9 on a Windows 8.1 machine (x64) using CUDA 6.0 and OPENGL as enabled flags, under Visual Studio 2012. Everything goes fine except the generation of highgui.dll file, because i get the following error:

looking in the code, windows.cpp and windows_w32.cpp have the same definitions of same functions. Is that a bug? How can i fix it?

yea. weird. if WITH_WIN32UI was set in cmake, it should have used windows_w32.cpp instead of window.cpp (without the 's' , btw) using both is clearly wrong

could you add the cmake output above ?
