Compiling OpenCV source code to Matlab - matlab

Question

I am trying to compile a C++ code in Matlab. The source code uses the OpenCV library.
when I write:
mex myfile.cpp
I get the following Error:
fatal error C1083: Cannot open include file: 'opencv2/opencv.hpp' No such file or directory
I am using Matlab r2012b and have Visual c++ 2010 express on windows 7.
Is there please any solution for this?
Thank you.
Edit: I did the following but get another error:
mex -v -largeArrayDims Calib.cpp -I"C:\opencv\build\include" ...
-L"C:\opencv\build\x86\vc10\lib" -lopencv_calib3d240d -lopencv_core240d ...

Answer 1

You should add include flags and linking libraries to the command line. That is,
mex myfile.cpp -I header_path -l opencv_libraries

Answer 2

Please try:
mex -largeArrayDims Calib.cpp -IC:\opencv\build\include -LC:\opencv\build\x86\vc10\lib...
-l opencv_calib3d240d -l opencv_core240d -l opencv_highgui240d -l opencv_imgproc240d
BTW, is there a special reason why you link with the opencv_< >d.lib rather than opencv_< >.lib files?
