#include <gwcore.hpp>

#include <tchar.h>
#include "test.gfu"



int main()

	return 0;
}

File: MSVCRTD.lib(exe_winmain.obj)

It has to do something with the includes. The gw is from Grit a very old framework. I am working with Visual Studio 2019


I have dllimport defined in some files if it helps:

1. hpp file:

1

#ifdef _GwOS_WIN
#define EXPORT		__declspec(dllimport)
#define PREEXPORT	__declspec(dllimport)
#define POSTEXPORT
#define EXPORT16	EXPORT
#endif /* __WIN32__ */


2. hpp file:

#define GWOCC_API __declspec(dllimport)
#endif

// This class is exported from the gwocc.dll
class GWOCC_API Cgwocc {
public:
	Cgwocc(void);
	// TODO: add your methods here.
};

extern GWOCC_API int ngwocc;

GWOCC_API int fngwocc(void);


3. hpp file:

#ifdef GWOCC_EXPORTS
#define GWOCC_API __declspec(dllexport)
#else
#define GWOCC_API __declspec(dllimport)
#endif

// This class is exported from the gwocc.dll
class GWOCC_API Cgwocc {
public:
	Cgwocc(void);
	// TODO: add your methods here.
};

extern GWOCC_API int ngwocc;

GWOCC_API int fngwocc(void);


and so on ...

how old? I assume you have a .lib or something to use your dlls, and if they were compiled too far back, you may have a 32 bit vs 64 bit problem, that is, the library isnt readable and so it can't find what is in there...

iirc, that happens when you don't chose «console aplication» as your project type

> referenced in function `func_test(void)'
¿are those your functions?
¿where are they defined?
¿did you add those files to your project?
