Hi, kyamagu

I rebuilded opencv 2.4.3 with VS2008, set system path as C:\opencv\build\x86\vc9\bin and used matlab 2008a to compile mexopencv, but my matlab crashed. What's wrong?
Thanks.

Matlab2008a does not support VS2010.

Nobody ever reported success with VS2008 + OpenCV 2.4.3 + Matlab. I don't have any clue of what's wrong with VS2008, but try building OpenCV from source with VS2008 and use that binary for mex.

I rebuilt OpenCV from source with VS2008 and copy the *.dll and *.lib files into C:\opencv\build\x86\vc9\bin and C:\opencv\build\x86\vc9\lib folder, but the matlab still crashed because of segmentation violation and the crash happened when matlab tried to compile VideoCapture function.

This is gonna be a hard debug. I would recommend you obtain a newer version of Matlab.

But if it's not possible, try debugging by start making a small C++ mex function that uses stdc++, linking some opencv function, etc. Also check Matlab documentation of your version of how to debug mex function in your environment.
