I am receiving the below error when trying to compile a cpp file using mex. Mex is configured to use 'MinGW64 Compiler (C++)' for C++ language compilation, but I am wondering how to go about enabling the compiler options stated in the error message. Steps for how to do this would be appreciated.
error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

Hi Ashley,
try to add the flag to the compiler options like this:
mex -v COMPFLAGS='$COMPFLAGS -std=c++11' yourmexfile.c

Thanks for the info. On my side in order to have the latest C++17 features, like any I used
mex COMPFLAGS=''$COMPFLAGS /std:c++latest'' yourmexfile.cpp
and it worked fine,
regards, Jérôme

It didn't work for me on MacOS. Following Mex Documentation i could see that for MacOS, MinGW and Linux compilers the following hast to be done:
mex -v CXXFLAGS='$CXXFLAGS -std=c++11' yourmexfile.c
