Programming This forum is for all programming questions. This page. Search Blogs. This, and other using directives are generally considered bad practice at file scope of a header file. Using-declarations can be used to introduce namespace members into other namespaces and block scopes, or to introduce base class members into derived class definitions. James that was my thought.

See if something like this works a bit better (for the moment, I've merged them into a single source file). #include namespace tools. As noted in the comment, you need to qualify G with the namespace.

namespace GSpace { class G { }; } class M { public: friend class. Here is a simple c++ program that demonstrates friend classes: Code: class A { friend class B; private: int var; }; class B { public: int GetVar() {.

All restrictions on regular declarations of the same names, hiding, and overloading rules apply to using-declarations:.

Visit paulsm4's homepage! That works for me too. In a includes B and B includes A, you solve circular inclusion by forwarding the declaration of one of the clases into the other one, as I did in my code.![]() This definition is treated as a definition of a namespace with unique name and a using-directive in the current scope that nominates this unnamed namespace.
