MEX can't find Intel Parallel Studio XE for Fortran 2017

"Error using mex

No supported compiler or SDK was found."

I have installed Matlab 2017a, Intel Parallel Studio XE Composer Edition for Fortran macOS 2017, both are trial versions, and Xcode 8.3.3, running on macOS 10.12.6. I also have installed Matlab 2016a.

When I type "mex -setup -v FORTRAN" I get the following:

"Verbose mode is on.

Looking for compiler 'Intel Fortran Composer XE' ...

Looking for environment variable 'IFORT_COMPILER17' ...No.

Looking for environment variable 'IFORT_COMPILER16' ...No.

Looking for environment variable 'IFORT_COMPILER15' ...No.

Looking for environment variable 'IFORT_COMPILER14' ...No.

Looking for environment variable 'IFORT_COMPILER13' ...No.

Executing command 'which ifort' ...No.

Did not find installed compiler 'Intel Fortran Composer XE'.

I have already reinstalled Intel Parallel Studio XE Composer Edition for Fortran macOS 2017 and it didn't work. When I compile prime.c it works.

mex yprime.c

Building with 'Xcode with Clang'.

MEX completed successfully.

But when I try to compile yprimef.F yprimefg.F I got the error already reported above.

solution

setenv('IFORT_COMPILER17','/opt/intel/compilers_and_libraries_2017.5.220/mac/');

mex -setup -v FORTRAN

change the setenv to your IFORT COMPILER version and path

I did exactly as you recommend, but only get:

setenv('IFORT_COMPILER20','/opt/intel/compilers_and_libraries_2020.2.258/mac/')
>> mex -setup Fortran -v
Verbose mode is on.

Any advice?

I was able to get mex fortran to run on OSX 10.15.6 after running into this error.

In addition to the instructions above, I opened /Applications/MATLAB_R2020b.app/bin/maci64/mexopts/intel_fortran.xml and replaced line 107

 	    <cmdReturns name="ifort --version | grep -Eo '[0-9]+\.[0-9]+\.[0-9]' | head -1" />

with

 	    <cmdReturns name="/usr/local/bin/ifort --version | grep -Eo '[0-9]+\.[0-9]+\.[0-9]' | head -1" />

Note that I had run

        mex.getCompilerConfigurations

prior to correcting the xml file. This was suggested in https://www.mathworks.com/matlabcentral/answers/512901-mex-xcodebuild-error-sdk-macosx10-15-4-cannot-be-located#answer_426086 . I am unsure whether both actions were needed, but everything seems to be working now. I am not sure what was causing

%         Executing command 'ifort --version | grep -Eo '[0-9]+\.[0-9]+\.[0-9]' | head -1'

to fail.
