compiling openCV 2.4.5 under VS 2012 x64

I just downloaded OpenCV 2.4.5 for Windows and tried to compile it using CMake 2.8.10.2 (GUI), but I get the following error when configuring cmake:

The CXX compiler identification is unknown
The C compiler identification is unknown
CMake Error at CMakeLists.txt:69 (message):
  CMake fails to deterimine the bitness of target platform.

    Please check your CMake and compiler installation. If you are crosscompiling then ensure that your CMake toolchain file correctly sets the compiler details.


Configuring incomplete, errors occurred!

I chose Visual Studio 11 Win64 compiler, but the same happens to other compilers. And I had the same error with 2.4.4. What can I do?

It seems like CMake didn't find Visual Studio 11.

Which version do you have? Professional or Express?

Also GPU module have several issues on Visual Studio 11 (because CUDA doesn't officially support latest Visual Studio). It's better to use Visual Studio 2010.

I already got some steps further, by selecting the correct VS version and by manually selecting my C and CXX compiler locations. However, rest of configuration keeps giving me a hard time, see: http://answers.opencv.org/question/13490/cmake-opencv245-windows-7-x64-not-finding-the/

I have the professional VS2012 version. VS2010 unfortunately isn't an option. I don't necessarily need CUDA, I'm more interested in OpenCL support.

Ben, I suggest you follow my topic posted. I got behind the step that gives you problems, and will put the solution in my topic!

Is that an answer or a comment? Thanks for pushing up this topic, anyway ;) No, I haven't found a solution to this yet. But I didn't investigate since then, as I had to focus on other things.

Hmm excuse me, but it was intended to push up the topic :)
