Creating DLL file in Qt and using it in Java

[sattu]

Hi everyone,

I am creating a simple shared library which contains the following files:
mylib.h and mylib.cpp

the code for mylib.pro is:

QT       -= gui
 
TARGET = myLIB
TEMPLATE = lib
SOURCES += mylib.cpp
 
HEADERS += mylib.h

QT       -= gui

TARGET = myLIB
TEMPLATE = lib
SOURCES += mylib.cpp

HEADERS += mylib.h

To copy to clipboard, switch view to plain text mode 

the code for mylib.h is:

#ifndef MYLIB_H
#define MYLIB_H
 
extern "C"{
__declspec(dllexport) int __stdcall hello();
}
 
#endif // MYLIB_H

#ifndef MYLIB_H
#define MYLIB_H

extern "C"{
__declspec(dllexport) int __stdcall hello();
}

#endif // MYLIB_H

To copy to clipboard, switch view to plain text mode 

the code for mylib.cpp is:

#include "mylib.h"
 
__declspec(dllexport) int __stdcall hello()        
{
    return 56;     [QUOTE]hello() is a simple function which returns 56[/QUOTE]
}

#include "mylib.h"

__declspec(dllexport) int __stdcall hello()        
{
    return 56;     [QUOTE]hello() is a simple function which returns 56[/QUOTE]
}

To copy to clipboard, switch view to plain text mode 

After building the project, i am getting a myLIB.dll file in debug directory. I am able to use this DLL in a visual C# project by referencing to the DLL in C# code.
But i am not able to use the hello() function of the DLL in java.


So, can anyone please tell me the correct way of creating a DLL in Qt, which i can further use in Java?


Thanks in advance,

With regards,
