This is on macOS. Since updating to r2022, I've been getting the following issue when running a newly-compiled Fortran mex-file. The mex-file compiles correctly from what I can see using Intel ifort and mex, but when I run it in Matlab, I get the error below.
It seems like there is a diffrerence in libifcore.dylib included in Matlab and the one with the Intel compiler. The symbol _for_getenv_err exists in the libifcore.dylib that comes with the Intel compiler. Does anyone have any suggestions?
Invalid MEX-file '***.mexmaci64': dlopen(***.mexmaci64, 6): Symbol not found: _for_getenv_err
Referenced from: ***.mexmaci64
Expected in: /Applications/MATLAB_R2022a.app/bin/maci64/../../sys/os/maci64/libifcore.dylib

Which Intel Fortran was being w? In that release only Intel Parallel Studios Fortran 2019 and 2020 were supported.

Hi Elizabeth,
As per my understanding suggests that there is a symbol missing in the libifcore.dylib library that is required by your Fortran mex-file. The error encountered is because MATLAB R2022a does not supports Gfortran for Mac OS.
Please refer to the following documentation to refer to the Supported and Compatible Compilers:
https://www.mathworks.com/support/requirements/supported-compilers.html
For a similar error please refer to the following MATLAB Answer:

Hope this helps!
