http://stackoverflow.com/questions/20205215/circular-dependencies So to solve circular dependencies you can do this A.hpp class B class A public int foo B b int bar B.hpp class A class.. B A m_a public int foo explicit B A a m_a a A.cpp #include A.hpp #include B.hpp int A foo B b return 2 b foo int A bar return.. foo B b return 2 b foo int A bar return 42 B.cpp #include A.hpp #include B.hpp int B foo return m_a bar share improve this..
Two classes and inline functions http://stackoverflow.com/questions/2233149/two-classes-and-inline-functions other with include guards preventing infinite recursion. A.hpp #ifndef INCLUDE_GUARD_B9392DB18D114C1B8DFFF9B6052DBDBD #define.. struct A struct B A p void bar #include A.hpp inline void B bar if p p foo #endif share improve this answer..
