Hi,
As per my understanding you want to compile a Fortran File using the mex command with the verbose mode enabled (mex -v -R2018a twotimes.F), and MATLAB does not attempt to use the configures "ifort" compiler and it looks for the "gfort" compiler which is not found.
One of the possible workarounds for this is as follows:
Firstly Please refer to the following documentation to refer to the Supported and Compatible Compilers and check if you have all the requirements already setup:
- Edit "/usr/local/MATLAB/R2016b/bin/glnxa64/mexopts/gfortran.xml"
- In the line beginning with "LINKLIBS=..." remove both references to gfortranbegin
- Add "-lgcc_s.1" to the end of that line inside the quotes
- At the bottom of the file, within the "GFORTRANBEGIN_LIBDIR" block, replace 'dirExists name="$$"' with 'dirExists name="/"'.
- Save the file and set up the Fortran compiler as normal. This worked for me on Gentoo using gfortran 8.2.0-r6.
The following MATLAB Asnwer has a similar workaround. Please refer to the link below for further understanding:
Hope this helps!
