It's not an error, it's a warning. And this has nothing to do with
C++. Is this your own private project, or is it one I can go look up?
I looked in the preprecessor output(_aggstate.i) and see this single
occurrence of aggstate_init
#line 1191 "_aggstate.cxx"
extern "C" __declspec(dllexport) void init_aggstate(void)
{
aggstate_init();
}
is this some feature of C++ or is there a real issue here?
My guess is that you have listed "init_aggstate" in the ".def" file that
lists the exported functions. That's the first export specification.
You are also using __declspec(dllexport) in the function definition, and
that's the second export specification. When you use
__declspec(dllexport), you don't need the ".def" file.
