Hello everyone,
Can anyone please provide me with the right flags to mex .c with openmp?
The following produces the best results on mac:
mex CC="gcc-4.2" LD="gcc-4.2" COPTIMFLAGS="$COPTIMFLAGS -fopenmp -O2 -DNDEBUG" LDOPTIMFLAGS="$LDOPTIMFLAGS -fopenmp -O2" -lgomp filename.c
I would like the, windows 7 x64, windows 7 x86, linux x64, linux x86 equivalent of the above.
Regards,
Jayveer

On Windows using Microsoft Visual Studio I add the /openmp option to the relevant line of my mexopts.bat file, thus:
set COMPFLAGS=... /openmp
On Windows 7 my mexopts.bat file is found in: C:\Users\$USERNAME\AppData\Roaming\MathWorks\MATLAB\R20XXx

thank you.
matlab support suggested: mex -v mymex.c COMPFLAGS="/openmp $COMPFLAGS"
Both solutions work. I prefer the second.
