MATLAB: Problem with MEX-file: Could not find the compiler “ifort” on the DOS path.

batch filecompilersdk

Hey, I have a big problem with compiling a MEX-file. The "mex -setup" ist no problem:
mex -setup
Welcome to mex -setup. This utility will help you set up a default compiler. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2011b/win64.html
Please choose your compiler for building MEX-files:
Would you like mex to locate installed compilers [y]/n? y
Select a compiler: [1] Microsoft Software Development Kit (SDK) 7.1 in C:\Program Files (x86)\Microsoft Visual Studio 10.0
[0] None
Compiler: 1
Please verify your choices:
Compiler: Microsoft Software Development Kit (SDK) 7.1 Location: C:\Program Files (x86)\Microsoft Visual Studio 10.0
Are these correct [y]/n? y
************************************************************************* Warning: MEX-files generated using Microsoft Windows Software Development Kit (SDK) require that Microsoft Visual Studio 2010 run-time libraries be available on the computer they are run on. If you plan to redistribute your MEX-files to other MATLAB users, be sure that they have the run-time libraries. *************************************************************************
Trying to update options file: C:\Users\user\AppData\Roaming\MathWorks\MATLAB\R2011b\mexopts.bat From template: C:\PROGRA~1\MATLAB\R2011b\bin\win64\mexopts\mssdk71opts.bat
Done . . .
************************************************************************ Warning: The MATLAB C and Fortran API has changed to support MATLAB variables with more than 2^32-1 elements. In the near future you will be required to update your code to utilize the new API. You can find more information about this at: http://www.mathworks.com/support/solutions/en/data/1-5C27B9/?solution=1-5C27B9 Building with the -largeArrayDims option enables the new API. ************************************************************************
After that I want to start my programm and the following error occurs:
Error: Could not find the compiler "ifort" on the DOS path. 
       Use mex -setup to configure your environment properly. 
C:\PROGRA~1\MATLAB\R2011B\BIN\MEX.PL: Error: Unable to locate compiler.
Error using mex (line 206) Unable to complete successfully.
Error in make_FAST_SFunc (line 64) mex('-v' , … %verbose
I don´t think, that I have an "ifort-compiler". I tried to modify the batch-file with new PATH, COMPFLAG, etc. for SDK v7.1. but I don´t have enough experience with Fortran. I hope you understand my problem and somebody could help me.
Best regards,
Sebastian

Have you installed Intel Visual Fortran Composer XE 2011 or Intel Visual Fortran 11.1 ? You will need one of the two.
