Using #defines within generated C++ code

Is there a way to insert defined values (using #define in an included header file) into MATLAB Coder generated C++ code?

For example,

I want to create a function that breaks if a flag is set (exitFlag). In my included header I have

#ifdef GPP
#define EXIT (exitFlag)
#else
#define EXIT (false)
#endif

And I want to use in MATLAB something like the following

exit_entrypoint = false;
if coder.target(RTW)
    coder.cinclude('headerWithDefine.h');
    % <insert code that sets exit_entrypoint = to EXIT>
end

Let me know if this is possible or if there's a work around. Thanks.

Answer 1

Why dont you include the header-guard before hand and then include the header using coder.cinclude() ?
