xcrun: error: SDK "macosx10.13.4" cannot be located

I wanna run a C++ file 'mexCoarseGrainGamma.cpp', but there is a error, such like,

>> mex mexCoarseGrainGamma.cpp
Building with 'Xcode Clang++'.
xcrun: error: SDK "macosx10.13.4" cannot be located

xcrun: error: SDK "macosx10.13.4" cannot be located

xcrun: error: SDK "macosx10.13.4" cannot be located

xcrun: error: SDK "macosx10.13.4" cannot be located

xcrun: error: SDK "macosx10.13.4" cannot be located

MEX completed successfully.

Do anyone know what is the problem? And how to fix it? Thank you in advance.

This suggests that the Xcode compiler is not being found. Its probably because of an out of date options file. This might help :

If not, what is the output of running the following command in MATLAB?

mex -v -setup

Thank you so much! I changed the compile path of Matlab to Xcode, then it worked. Maybe it could work also, thank you anyway!

Yes, you're right, I just did like this.
