use libs under qt4

Hi everybody,

NOW:
OS:WINXP PRO
QT: 4.1.1
Compiler: MINGW 4.1

Bevor:
OS: WINXP
QT: 3.3.4
Compiler: .NET

I have programed in the past a small program that use a dll, h, lib (original from device)
I have not compiled this, its original delivered.

The program works fine on qt3 but not in qt4. If i include this header file i get erros:

Code:

---

#ifdef __cplusplus
extern "C" {
#endif
 
#define FUNCTION __declspec(dllimport)
 
FUNCTION long __stdcall OpenDevice(long CardAddress);
FUNCTION __stdcall CloseDevice();
FUNCTION long __stdcall ReadAnalogChannel(long Channel);
FUNCTION __stdcall ReadAllAnalog(long *Data1, long *Data2);
FUNCTION __stdcall OutputAnalogChannel(long Channel, long Data);
FUNCTION __stdcall OutputAllAnalog(long Data1, long Data2);
FUNCTION __stdcall ClearAnalogChannel(long Channel); 
FUNCTION __stdcall ClearAllAnalog();
FUNCTION __stdcall SetAnalogChannel(long Channel); 
FUNCTION __stdcall SetAllAnalog();
FUNCTION __stdcall WriteAllDigital(long Data);
FUNCTION __stdcall ClearDigitalChannel(long Channel);
FUNCTION __stdcall ClearAllDigital();
FUNCTION __stdcall SetDigitalChannel(long Channel);
FUNCTION __stdcall SetAllDigital();
FUNCTION bool __stdcall ReadDigitalChannel(long Channel);
FUNCTION long __stdcall ReadAllDigital();
FUNCTION long __stdcall ReadCounter(long CounterNr);
FUNCTION __stdcall ResetCounter(long CounterNr);
FUNCTION __stdcall SetCounterDebounceTime(long CounterNr, long DebounceTime);
 
#ifdef __cplusplus
}
#endif

---

error:

Code:

I have included the libs like in qt3 .pro file:

Code:

---

win32:LIBS  += K8055D_C.lib

---

So i use the same filosofie to program it in qt4, but why qt4 have a problem with this header file?

IMHO this is not a problem from the differences between Qt3 and Qt4, but rather with the different compilers. Obviously MINGW does not understand the code in the header file.

Just a shot in the dark: Try removing the stdcall stuff.

Hi,
You think:

Code:

---

FUNCTION  CloseDevice();

---

instead of:

Code:

---

FUNCTION __stdcall CloseDevice();

---

It not works :(

But __stdcall is not supported by mingw i think, because if i edit the header file to:

Code:

---

#ifdef __cplusplus
extern "C" {
#endif
 
#define FUNCTION __declspec(dllimport)
 
FUNCTION long __stdcall OpenDevice(long CardAddress);
 
 
#ifdef __cplusplus
}
#endif

---

I can use this function "OpenDevice" without problem.

What should i do?

have nobody a idea how to use my header file? I have there a problem with stdcall i think :o

Code:

---

FUNCTION __stdcall CloseDevice();
FUNCTION __stdcall ReadAllAnalog(long *Data1, long *Data2);
FUNCTION __stdcall OutputAnalogChannel(long Channel, long Data);
FUNCTION __stdcall OutputAllAnalog(long Data1, long Data2);
FUNCTION __stdcall ClearAnalogChannel(long Channel); 
FUNCTION __stdcall ClearAllAnalog();
FUNCTION __stdcall SetAnalogChannel(long Channel); 
FUNCTION __stdcall SetAllAnalog();
FUNCTION __stdcall WriteAllDigital(long Data);
FUNCTION __stdcall ClearDigitalChannel(long Channel);
FUNCTION __stdcall ClearAllDigital();
FUNCTION __stdcall SetDigitalChannel(long Channel);
FUNCTION __stdcall SetAllDigital();
FUNCTION __stdcall ResetCounter(long CounterNr);
FUNCTION __stdcall SetCounterDebounceTime(long CounterNr, long DebounceTime;

---

All of those functions are missing the return value type. Did you try to add "void" between "FUNCTION" and "__stdcall"?

Hi Jacek!!

Thank you very much ;) it works..How did you find that out?

You wrote that "FUNCTION long __stdcall OpenDevice(long CardAddress);" works, so I focused on the differences between this and other declarations.
