Dll compatibility between compilers

Question

Is there some way to make c++ dlls built with diffrent compilers compatible with each other? The classes can have factory methods for creation and destruction, so each compi

Answer 1

You can as long as you only use extern "C" functions.

This is because the "C" ABI is well defined, while the C++ ABI is deliberately not defined. Thus each compiler is allowed to define its own.

In some compilers the C++ ABI between different versions of the compiler or even with different flags will generate an incompatable ABI.
