Thread Subject:

mex options

i am compiling a set of *.for (Fortran) files to create a mex file but encountered a problem to which a solution would be to modify some mex options. exactly what i am after is as follows:

the /assume:backslash option is on and tries to interpret backslashes in character strings as C escape sequences. this should be removed. alternatively, if "mex" won't allow me to do that, could try adding "/assume:nobackslash".

problem is do not know where to change it and how. I have Visial Fortran Compiler 11.1 tested and working on Matlab 2010a.

mex options files are in the following directory (modify as appropriate for your system):

[matlabroot '\bin\win32\mexopts']

The file name to look for should be something like:

intelf11msvs2005opts.bat (for mex functions)

or

intelf11msvs2005engmatopts.bat (for engine applications)

Inside this file, modify the COMPFLAGS line. In addition to your problem, I would advise deleting the /fixed option from this line. That will allow you to compile .f90 files as free format.

I'm not sure Steve Lionel <http://software.intel.com/en-us/forums/showthread.php?t=73523> gave you the right advice. I think the compiler command you need is /assume:nobscc and if you look into the mexopts.bat file you'll see /assume:bscc which is causing the problem.
I think you need to modify intelf12msvs2008opts.bat BEFORE you do mex -setup or modify the mexopts.bat file if you've already done the mex-setup.
