Matlab does not find Intel XE 2020 Fortran Compiler on Mac

Hi everyone,

I have a set of Fortran code files that I need to compile on my Mac using Matlab 2020b.

To do so, I have downloaded Intel Parallel Studio XE 2020.

When I run:

mex -setup Fortran -v 

I however get to the following:

mex -setup Fortran -v
Verbose mode is on.
... Looking for compiler 'Intel Fortran Composer XE' ...
... Looking for environment variable 'IFORT_COMPILER20' ...No.
... Looking for environment variable 'IFORT_COMPILER19' ...No.
... Looking for environment variable 'IFORT_COMPILER18' ...No.
... Executing command 'which ifort' ...Yes ('/usr/local/bin/ifort').
... Looking for folder '/opt/intel/compilers_and_libraries_2020.2.258/mac/bin/intel64' ...Yes.
... Looking for environment variable 'IFORT_COMPILER20' ...No.
... Looking for environment variable 'IFORT_COMPILER19' ...No.
... Looking for environment variable 'IFORT_COMPILER18' ...No.
... Executing command 'which ifort' ...Yes ('/usr/local/bin/ifort').
... Looking for folder '/opt/intel/compilers_and_libraries_2020.2.258/mac/compiler/lib' ...Yes.
... Executing command 'ifort --version | grep -Eo '[0-9]+\.[0-9]+\.[0-9]+' | head -1' ...Yes ('19.1.2').
... Executing command 'xcrun -sdk macosx --show-sdk-path' ...No.
Did not find installed compiler 'Intel Fortran Composer XE'.

What am I missing?

Many thanks in advance!

I suspect you might need to install the xcode command line tools.

Thanks, that and some other environment variable setting did the job. All working now.
