MATLAB: Help with linking with mex

fortranMATLABmex

Hello,

I have windows 7 64bit with VS2010 installed with Intel visual fortran 12.0 and matlab 2011b. I ran the mex -setup and configured matlab to work with my fortran version. However, when I try to compile any of the included examples (e.g. timestwo.F) I receive:

mex timestwo.F

'link' is not recognized as an internal or external command, operable program or batch file.

C:\PROGRA~1\MATLAB\R2011B\BIN\MEX.PL: Error: Link of 'timestwo.mexw64' failed.

Any idea what's wrong and how to fix it?

Elad,

The MEX options file for Intel Fortran Composer XE 2011 with Microsoft Visual Studio 2010 professional linker points to the wrong installation directory in 64-bit MATLAB 7.13 (R2011b).

Workaround: Edit the intelf12msvs2010opts.bat file:

1. Open $MATLABROOT$\bin\win64\mexopts\intelf12msvs2010opts.bat

2. Edit line 22. Change:

set VSINSTALLDIR=%VS90COMNTOOLS%\..\..

set VSINSTALLDIR=%VS100COMNTOOLS%\..\..

3. Save the file

4. Run mex -setup again.

Microsoft Visual Studio 2005 Professional is required to use Intel Visual Fortan 10.1.

In this case, although Microsoft Visual Studio 2005 Professional was installed, the Windows environment variable 'VS80COMNTOOLS' was not set appropriately to point to the correct directory. 'VS80COMNTOOLS' needs to point to the following directory:

$VISUAL_STUDIO_ROOT\Common7\Tools\

where $VISUAL_STUDIO_ROOT is the directory where Microsoft Visual Studio is installed.

'VS80COMNTOOLS' environment variable is picked up by the following file:

intelf10msvs2005opts.bat

located at:

$MATLABROOT\bin\win32\mexopts

where 'MATLABROOT' is the root directory where MATLAB is installed and can be found by typing:

matlabroot

at MATLAB command prompt.

Seems like a permissions/UAC issue. Are you running the command from a directory that you have write access to? Also, try copying yprimef.F to a location in your home directory so that the MEX command doesn't attempt to write to the MATLAB installation root (inside C:\Program Files). If that still doesn't work, try starting MATLAB as Administrator and run the command.
