Segmentation Fault about mexopencv HOT 5 CLOSED

It's a known issue with binary OpenCV package. See the previous post: #4

from mexopencv.

I am not sure is the same thing at least the solution might be different, I have WinXP 32bits and my matlab version is for 32bits (R2009b), also I compile OpenCV using VS2008,
should I use VS2010 instead of VS2008 to compile mexopencv? or is it better to have OpenCV and mexOpenCV compiled with the same compiler?

Thanks in advance

The issue is that the OpenCV binary package contains incompatible dll files for some environment, and when it happens, compilation succeeds but an unexpected error occurs on execution. VS2010 might not have this compatibility issue and it's worth trying. The other solution as far as I know is to build OpenCV from source.

I find a solution in http://www.mathworks.com/matlabcentral/answers/9294-mex-dynamic-memory-management-issue-with-std-vector-in-linked-external-dll-segmentation-error

I posted here the solution also just in case,

remove the SECURE_SCL=0 option from the mex options file at

C:\Users(Username)\AppData\Roaming\MathWorks\MATLAB\R2009b\mexopts.bat

Then recompiled the mex file, now everything works like a charm - the function is returning the correct data and segmentation error no longer occurs.

Thanks Miguel! I would add this notice in readme!
