C ++ 2 DLL相互使用

Question

在c ++中是否可能包括彼此的2个DLL，因为它们每个都使用彼此的类（这是我的计划），这是否可行？

Answer 1

Yes, this is possible. Only you need to compile these dlls as a multi step process. To link a dll, you need a lib file from other dll. This means that you need:

1. Create stub implementation of DLL1. This will produce a .lib file for DLL1.
2. Link DLL2 with stub .lib pf DLL1.
3. Link DLL1 with real .lib of DLL2.
4. Relink DLL2 with real lib of DLL1.

Also note that DLLs in general have C interface. You can export classes, but be ready to have set of dlls for each version of used compiler.
