Load dll Library

[aminemaar]

Hello after building a DLL library with visual studio, I linked the DLL in my QT project but it not working

this my code

QLibrary myLib("DLLSUM.dll");
    myLib.load();
    typedef int(*FNPTR)(int a, int b);
    
    FNPTR pSum = (FNPTR) myLib.resolve("sum");

    if (pSum)
        qDebug() << "sum = " << pSum(5,2);
    else
        qDebug("DLLSUM not Loaded");

@aminemaar
And would you care to tell us what your qDebug() output...?

@JonB qDebug() return this message "DLLSUM not Loaded"

Hi
Could you try

 if (!myLib.load())
        qDebug() << myLib.errorString();

and see what it says ?

@aminemaar Why don't you simply link against this lib instead of loading it dynamically?
Also, you're using a relative path, depending on the current working directory QLibrary will simply not find the lib.

@mrjj thank's I knew the problem with

myLib.errorString();

@jsulm thank's the path was incorrect
