Error in building gateway C mex function for calling Fortran subroutine.

Hi,

I am using Matlab 2018a with following compilers:

'Microsoft Visual C++ 2017 (C)

Intel Parallel Studio XE 2015 for Fortran with Microsoft Visual Studio 2015.

I am trying to call fortran subroutine in simulink by building a C mex gateway routine.

I am following the instructions from Matlab doumentaion :https://www.mathworks.com/help/simulink/sfg/creating-level-2-fortran-s-functions.html

In the above documentaion, under the sub heading Building Gateway C MEX S-Functions on a Windows System there are instructions to compile the fortran subroutine. However, when I run the command :

mex -v -c toolbox/simulink/simdemos/simfeatures/srcFortran/sfun_atmos_sub.F ...
-f bin/win64/mexopts/intelf12msvs2008opts.bat

I recieve the following error:

Error using mex
C:\Program Files\MATLAB\R2018a\bin\win64\mexopts\intelf12msvs2008opts.bat is not a valid XML file.


Thanks
