Model acceleration in Matlab-Simulink (Mac OSX)

Question

I get this build error for a demo example in Simulink for model acceleration and Model referencing technique. I use Matlab R2013b in Mac OSX 10.9.5 and use Xcode 6.2/Clang++ as my C/C++ compiler. The error seems to be due to a missing/unknown type char16_t. The similar issue was resolved by using CFLAGS -Dchar16_t=UINT16_T for Matlab compiler for Mac OSX . I don't have issue with matlab compiler, but get the build error with compilation of simulink models (ie in sbuild function). Any clue how to resolve this build error?

Answer 1

#include <stdint.h>

is one way to get a declaration of char16_t . If you can't modify the code then you could use a forced include of that file (check compiler's documentation for what its option for forced include is).
