My Operating System is OSX 10.14, and I already install the newest Xcode

the Problem is:

'sh /var/folders/_j/by019xjs0gdcztvndfq5wsgr0000gn/T//mex_12850823584080_3626' is an invalid option

I was trying to compile a C file, which is a S-function for a simulink Model.

Hello,

I suggest checking the output of :

>>mex -setup -v

You may find something useful from it.

In addition, it might be the issue related path. Please check whether the Matlab is using the same shell with your current shell.

Please type:

1. echo $0

2. echo $SHELL

first in the regular terminal, then inside MATLAB with the '!' command

If you are using bash,

then do the following:

$> echo $MATLAB_SHELL

output

$> which bash

path_to_bash

$> export MATLAB_SHELL=path_to_bash

then start MATLAB from the same terminal.

If the issue still exists, it will be helpful to create a technical support case here: http://www.mathworks.com/support/servicerequests/create.html, copy and paste the verbose output and what you have tried then engineers will be able to reach out to you with following steps.
