I would like to point out that a substitution for the old flag -i8 is needed.

Not only does which not appear to find gfortran (while in the terminal it does), but it also cant find the libgfortranbegin.a folder.

Mex does work with C.

Discussion of libgfortranbegin at But after you hack gfortran.xml to remove the references to that library, the problem remains that no matter what you do, mex forces -i8 to be added to the end of FFLAGS.

That is a problem because -i8 is no longer used as a flag by gfortran.

Step 1 is to install gfortran for OS-X.

I picked mine up at Step 2 is to edit ApplicationsMATLABR2017b.appbinmaci64mexoptsgfortran.xml (or as appropriate for your MATLAB version.) Replacement version is enclosed; unzip and put into that directory.

Note: I made several changes compared to the MATLAB provided version from the Question you linked to.

I removed the several references to libgfortranbegin, and I added support for XCode SDK 10.12, and I coded the name of the fortran compiler as gfortrani8 in the FC assignment in the vars section.

The changes I made to libgfortranbegin and SDK 10.12 should not give anyone any trouble, but the gfortrani8 that I introduced does not exist elsewhere.

Step 3. well if you installed from that source I gave, just assume the answer you need here is usrlocalgfortranbin and go on to Step 4.

Otherwise, go to a terminal window and in a shell (bourne shell family, not csh or zsh) execute readlink (which gfortran) If it gives you back a non-empty answer then the result you need from this step is the directory of what it returns.

For example if it returns usrlocalgfortranbingfortran then the answer you need is usrlocalgfortranbin (If someone using Linux is trying to get some hints from this message, then readlink might not work for you: in that case ls -l (which gfortran) and take the directory of what is returned.) What you need here is the name of the directory that the gfortran executables are really installed in, which is probably the same place that gcc is really installed in.

This will likely not be usrlocalbin even though there may be a usrlocalbingfortran -- that probably points off to the real directory.

Step 4: download the file gfortrani8.zip that I enclose, and unzip it.

Now copy that shell script into the directory found through step 3.

If you received this message when you mexd: Error using mex gfortran: error: unrecognized command line option -i8; did you mean -k8 then you need to be sure to install this gfortrani8 script.

If you receive this message: Error using mex usrlocalgfortranbingfortrani8: No such file or directory then you did successfully install my gfortran.xml but you did not install my gfortrani8 (or did not get it into the right place.) Step 5: go into MATLAB and delete(fullfile(prefdir, mexFORTRANmaci64.xml )) and do not worry if it says it did not already exist.

Step 6: in MATLAB, mex -setup fortran If it tells you the compiler was found, then you should be able to proceed with compiling.

If you did use the -client engine option then what was produced will be an external executable that you would execute with the system() or commands.

Step 10: curse when your program runs part way and then crashes.

Could you please tell me what does the gfortrani8 do Is it a compiler.

I could not find a way back then to get mex to stop inserting -i8 so I instead took the route of intercepting the call to the compiler, removing the -i8, and then calling the real compiler.

Note that MacOS Sierra and MacOS High Sierra might disregard DYLDLIBRARYPATH.

For those two operating systems, it might be necessary to put symbolic links from usrbin to matlabroots binmaci64 and sysosmaci64.

I have not tried that yet so I am not sure of the exact steps.
