Re: Exporting static member functions
Other than the fact that the members are private in your example, it works
for me.
Have you linked with the import library created by the creation of the dll
with the static methods?

I've succcessfully created a DLL full of classes that I've exported to
use in another DLL. But I have a class that full of static member
functions and the function names arent resolving
When I try to create a new DLL, importing the class definitions, I get
unresolved external errors, but only for the static member functions.
Why is that?
Shouldnt the class be imported when its declared?
Below is the class definitions
devlibrary.h - Included in my stdafx.h for both DLLs
#define DEV_DLL_EXPORT __declspec ( dllexport )
#define DEV_DLL_IMPORT __declspec ( dllimport )
#ifdef _DEVLIBRARY_DLL
#define DEVLIBRARY_CLASS DEV_DLL_EXPORT
#else
#define DEVLIBRARY_CLASS DEV_DLL_IMPORT
#endif
cpstinterface.h
class DEVLIBRARY_CLASS CPSTDriverInterface
{
static short GetCnlVarsCount();
static CCnlVar *GetAllCnlVar(short var_rank);
static CCnlVar *GetAllCnlVar(char *szProtVarName);
}
main.cpp
#include "cpstdriverinterface.h"
{
...
dwNumOfVars = CPSTDriverInterface::GetCnlVarsCount();
...
}
Error
error LNK2001: unresolved external symbol "__declspec(dllimport)
public: static short __stdcall
CPSTDriverInterface::GetCnlVarsCount(void)" (__imp_?
