Invalid MEX-file about mexopencv

[kyamagu]

Do you set up your SYSTEM PATH?

If you mean for MATLAB, then yes, it is setup as under

C:\Program Files\MATLAB\R2012a\bin;

I also added the mexopencv path to MATLAB

>> addpath('C:\opencv\matlab\trunk')

>> path

MATLABPATH

C:\opencv\matlab\trunk

No, I mean your SYSTEM PATH.

I added C:\opencv\build\x64\vc10\bin and C:\opencv\build\x64\vc10\lib to my SYSTEM PATH and carried out the whole process again. I was able to build successfully but when I try executing a function, MATLAB crashes.

I even tried copying all the OpenCV dlls into the +cv folder but to no avail

Are you using VC2010 compiler in Win 64-bit? You must use Windows SDK compiler in 64-bit arch.

Ok. Thanks. I installed Windows SDK and then carried out the process but I got an error

>> result = cv.filter2D(img, ker)
Error using cv.filter2D
Unexpected Standard exception from MEX file.
What()
is:C:\slave\WinInstallerMegaPack\src\opencv\modules\core\src\convert.cpp:274:
error: (-215) mv[i].size == mv[0].size && mv[i].depth() == depth

Based on htaichiwang comment I then rebuilt with -D_SECURE_SCL=0 and now the function runs fine. Even UnitTest ran fine.

Closing this issue. Thanks for the support. Looking forward to using this package.
