this is a known problem , when trying to build opencv libs using mingw

please go back to cmake, disable precompiled headers, clean your build folder,and try again.

Now i get these errors gcc: error: Files\: No such file or directory

gcc: error: (x86)\opencv\sources\3rdparty\include\ffmpeg_: No such file or directory

C:\MinGW\bin\windres.exe: preprocessing failed.

and further down:

which mingw is it, exactly ? (you have to use some mingw64, the 32bit version won't do)

did you really clean the build folder before running cmake again ?

add the cmake output to your question (it's long..)

otherwise, no idea.

I just deleted the folder i called MyopenCV

I had the 32 bit version, and i now have the 64 bit one, but now i get a new error:

i can only guess, but maybe you setup the compiler related things wrong, when running cmake.

try to use cmake-gui, give it the path to mingw32-make.exe, it should infer the other tools from there.

@Swagsquad: Could you solve the problem ? I am having nearly the same, see http://answers.opencv.org/question/18...
