MATLAB: No supported compiler was found.

Question

Upon trying to compile a file using mex, I receive the following error message:

Error using mex

No supported compiler was found.

I installed Visual Studio 2017 with support for C++ and actually

mex -setup C++

lets me choose my compiler.

Which additional diagnostics could I run in order to pin down the problem?

Answer 1

If you just run

>> mex -setup

it should present you with the compilers that Matlab can actually see. That should provide a clue.
