clibgen c++ on MacOS/MATLAB2019b cannot use standard library

Hi all,

I am trying to bind c++ header-only to MATLAB, as described in the documentation.

It works for super-basic code, but from the moment I need the slighest include from the standard library, e.g. iostream, it throws a bunch of errors when clibgen tries to parse the file.

For example, this simple code pulls one the official cpp example (and therefore theoretically works) and tries to compile it:

copyfile(fullfile(matlabroot,'extern','examples','cpp_interface','school.hpp'),'.','f')
clibgen.buildInterface("school.hpp") % buildInterface can be replace by generateLibraryDefinition it leads to the same error

and it leads to the error displayed in full at the end of this message.

I am on MacOSX12.3, on a MacBook Pro 2020 with an intel chip and latest Xcode (clang 13 I believe) using MATLAB 2019b

Does anyone has a workaround that issue?
