mex -setup can't find compiler for MATLAB 2017b on macOS High Sierra 10.13.1 and Xcode 9.1

I'm trying to add C and C++ compiler for MATLAB 2017b on my mac but it gives error

/bin/bash: sh: command not found

and

Warning: Xcode appears to be installed, but it has not been configured.  Run "osascript -e 'do shell script "xcode-select -switch /Applications/Xcode.app" with administrator privileges'" to configure Xcode.  You must be an administrator of this computer to complete this action.

So, when I run osacript... it gives error

/bin/bash: osascript: command not found
ans =
   127

I already did

sudo xcode-select -switch /Applications/Xcode.app/

and changed

MACOSX_DEPLOYMENT_TARGET="10.13"

which was 10.9 in clang_maci64.xml and clang++_maci64.xml files. Can anybody help me to solve this issue. Thank you.

You have to add the paths in the

/App../MATLAB../bin/maci64/mexopts/clang++_maci64.xml /App../MATLAB../bin/maci64/mexopts/clang_maci64.xml

to the SDK10.13 inside your XCode. Then it will find the compiler. To check that this is the problem you can run mex -v -setup C++. If it can't find the SDK there you have to add it inside the xml file.

Hi Constantin, could you please explain more about the procedure? I faced the same issue and not sure what do you mean by "add the paths in the ... to the SDK10.13 inside XCode", many thanks!
