Matlab wrapper compile: char16 is not defined

I am on a Mac OSx, using Matlab2013a, 2013b, or Matlab2014a.

When trying to compile my wrappers, I get the following error.

In file included from ./io/ApiPrintf.cpp:

In file included from ./io/./matlabio.h:

typedef char16_t CHAR16_T;

First, you can try adding

export CXXFLAGS=" -std=c++11"

to the top of your ISSM configure script.

This is the easiest fix.

If you are running with Dakota and boost, however, this might

create a link error. If it does, another working solution to this error is to update the

tmwtypes.h file in matlab

cd /Applications/MATLAB_R2013a.app/extern/include (or whatever is your version of matlab)

make a copy of the tmwtypes.h in case you want to revert back later

(you will probably have to use sudo here).

sudo cp tmwtypes.h tmwtypes.h.copy

Then:

edit line 819 in tmwtypes.h to say:

typedef UINT16_T CHAR16_T;

instead of:

typedef char16_t CHAR16_T;

(again, you might have to use sudo to do this)
