Exporting static data in a DLL

Question

I have a DLL which contains a class with static members. I use __declspec(dllexport) in order to make use of this class\'s methods

Answer 1

My guess is that the class which uses the DLL should see dllimport instead of dllexport in the header. If I am correct, this can typically be achieved by defining a preprocessor macro like:

#ifdef EXPORTING
#define DECLSPEC __declspec(dllexport)
#else
#define DECLSPEC __declspec(dllimport)
#endif

and then use it in the class declaration:

class DECLSPEC Test{
protected:
    static int d;
public:
    static void m(){}
}

So that in Test.cpp (or wherever it makes sense in your DLL project) you can specify that you are exporting so that it will be exported with dllexport:

#define EXPORTING
#include "Test.h"

int Test::d;

while the other project, which does not define EXPORTING, will see dllimport.

Does it make sense?
