Compiling Mex with GCC on Windows

Hi

Any idea how to compile Mex files with GCC on Windows, other than using gnumex?

Best Regards

gnumex may be your best bet; compilers that MEX supports does not include gcc on Windows. Just curious -- Is there a particular reason you need gcc? The Windows SDK 7.1 is free (as in beer, at least) and full-featured.

I have a piece of code that uses some declarations which are slightly different in GCC then microsoft visual C++. The mex compilation works perfectly on Linux with GCC and gives errors on Windows with Visual C++ 2010 such as:

error C2143: syntax error : missing ';' before 'const' 
error C2065: 'dim' : undeclared identifier 
error C2109: subscript requires array or pointer type error C2065: 'dim' : undeclared identifier 
error C2109: subscript requires array or pointer type 
error C2065: 'dim' : undeclared identifier error C2109: subscript requires array or pointer type 
error C2143: syntax error : missing ';' before 'type' 
error C2143: syntax error : missing ';' before 'type' and so on...

Okay, thanks for the clarification.

Solved. Used Gnumex with MinGW, Cygwin was not working with Gnymex, I do not know why. Followed the instructions at Gnumex page, which is simple, just give the path to MinGW compiler root folder etc.

When it creats mexopts.bat, use: mex -f c:\gnumex\mexopts.bat c:\progra~1\MATLAB\R2012a\extern\examples\mex\yprime.c

to compile mex file.
