[Mingw-users] .def file for classes and functions

[jayshankar n. <n_j...@ya...>]

MinGW Gurus,

I have member function in class A of DLL1 accessing the member function of class B of DLL2 and viceversa.

This results in a cyclic dependency of dll on each other for linking. All the undefined reference.

My question is can i create a .def file for all the undefined references and create a lib.a file(dlltool).

For a function i can simply put its name. But for class and its respective memeber functions whats the naming convention

For example 
class A{
public:
getInstance();
send(enum something);

}
func();

Example of .def i have written, which my guess is wrong as its  not linking. 
LIBRARY DLL2.DLL
EXPORTS
func
A::getInstance

dlltool -d dll1.def -l libdll.a

Appreciate your reply.

Thanks,
Jay
