I'm trying to call an external C++ function from Matlab to make it run faster.
I tried "coder.ceval", and got ERROR "The coder.ceval function is not supported in MATLAB"
I then tried "mex foo.cpp", and got ERROR "xcrun: error: SDK "macosx10.14.4" cannot be located"
I'm using "MacOS Mojave 10.14.5"
Does anybody know how to call C++ function from Matlab? Thank you sooooo much! I'm already driven crazy by this. T_T

Starting in 19a, you can call C++ libraries directly in MATLAB: https://www.mathworks.com/help/releases/R2019a/matlab/call-cpp-library-functions.html

I came across the same issue. Apparently, the mex command cannot find the SDK. I think the reason is that the SDK version has too much details (i.e. the 10.14.4 version number is unnecessary.)
To allow matlab to correctly locate the SDK, try the following command
mex SDKVER= foo.cpp
This basically sets the SDK version to null. It worked for me, hope that helps.

Thanks for this easy fix! From my experience with MEX on Windows, some xml files must contain a specific SDK version target but it would a lot more complicated to modify the xml file that comes with MATLAB.
