// so a cool trick with macros in C (and C++) is that since macros inside of
// macros are stille evaluated by the preprocessor, you can use macro names as
// parameters to other macros (and even construct macro names out of out of
// parameters!) - so using this trick if we have some macro like
// this:

#include <stddef.h>

#define MY_TYPES_ITER(_F, ...)   \
    _F(FOO, foo, 0, __VA_ARGS__) \

Things to remember when compiling/linking C/C++ software

by Angel Leon. March 17, 2015.

Include Paths

On the compilation phase, you will usually need to specify the different include paths so that the interfaces (.h, .hpp) which define structs, classes, constans, and functions can be found.

With gcc and llvm include paths are passed with -I/path/to/includes, you can pass as many -I as you need.

In Windows, cl.exe takes include paths with the following syntax: /I"c:\path\to\includes\ you can also pass as many as you need.
