Matlab 2016a mac - gfortran and intel compilers

Hello

I have managed to get mex (2016a) working with mac sierra and the latest xcode (clang) using the instructions given elsewhere on this list. However I couldn't do the same for gfortran and the latest intel compilers (icc and ifort 17) even after modifying the xml files to accommodate the same changes made in the clang files. Here is the output of the command "mex -v -setup FORTRAN".

Error using mex
No supported compiler or SDK was found. For options, visit
http://www.mathworks.com/support/compilers/R2016a/maci64.html.

Note that, on a terminal, the command "which ifort" returns "/usr/local/bin/ifort" and "ifort --version" returns "ifort (IFORT) 17.0.4 20170411".

I know that the above compilers (gfortran 6, ifort and icc 17) are not supported but I wonder whether someone out there got them working somehow.

Many thanks

Ed

Before you run the mex setup, use

setenv('PATH', [getenv('PATH') ':/usr/local/bin'] )

[Ed Mendes]

Many thanks. It was part of the solution. I had to issue the command "sudo ln -s /opt/intel /opt/intel/compiler" so that mex -setup FORTRAN finds the right path. After I have done that, I had no problem to compile and run "fulltosparse.f".

[ajay kumar]

I typed in command window

sudo ln -s /opt/intel /opt/intel/compiler

Undefined function or variable 'sudo'.

came error

please clear it

[Ed Mendes]

If you do not have sudo installed in your system, you can log in as root and issue a command that allows matlab to find the compiler.

[Walter Roberson]

The sudo would have to be typed in the Terminal app that you can find in the Utilities folder of Applications

Alternately, inside MATLAB you could use

!sudo ln -s /opt/intel /opt/intel/compiler

The ! tells MATLAB to send the command to your login shell.
