Matlab 64 bit Windows 7 compilation error when linking against self-compiled OpenCV about mexopencv HOT 6 CLOSED

Can you try VC++ 2010 Express and see if this happens?

from mexopencv.

A minor comment, the first command executed shows: -DSECURE_SCL=1 it should be -D_SECURE_SCL=1, are you sure it's not a typo? Also check that you have C:\opencv\build\x64\vc9\bin on the Windows PATH (to fix the "specified module could not be found" error)

The linker error is probably due to building OpenCV as 32bit binaries. Rebuild them as 64bit and it should work fine. The error you got from using prebuilt is probably due to not setting the path environment variable to the correct OpenCV binaries as @amroamroamro mentioned.

I went through the same exercise as above using VS2010 Express and Windows SDK 7.1 and experienced exactly the same problem. It turns out that by setting _SECURE_SCL=0 in cv.make, keeping the default mexopts.bat (as generated by mex -setup), and link to the pre-compiled library in opencv\build\x64\vc10\lib, the problem is resolved. The installation I have is: 64-bit Matlab 2011b on Windows 7, OpenCV 2.4.2, Visual Studio 2010 Express and Windows SDK 7.1.

@kyamagu: I think this issue can be closed, given the recent _SECURE_SCL fix

@amroamroamro Yes, the recent commit should have fixed this.

Please reopen if this bug happens with the latest commit.
