Question

Is it possible to hide an

#include <header.h>  //from library B

from projects using the library A?

I need to keep the include there because otherwise my library A won’t compile, but as that header is from other library B that shouldn’t be visible for the main project, the main program tries to find that header.h and compilation fails.

Answer 1

You could put it inside an #ifdef and define the symbol only when compiling library A:

#ifdef INCLUDE_FROM_LIBRARY_B
#include <header.h>  //from library B
#endif //INCLUDE_FROM_LIBRARY_B

Update: but probably the best option is @Robinson’s suggestion above: don’t include it in any header file, only in .cpp files when needed.
