Generate include file name in a macro

Question

I\'m trying to generate include file name in macro. This is supposed to be legal in C++:

#define INCLUDE_FILE \"module_impl_win.hpp\"
#include INCLUDE_FILE
<         


        

Answer 1

I'd do this using a helper quoting macro. Something like this will give you what you want:

#define QUOTEME(M)       #M
#define INCLUDE_FILE(M)  QUOTEME(M##_impl_win.hpp)

#include INCLUDE_FILE(module)
