Prl libsfile WIndows VS C++

Bipman

Hi all.

I've downloaded the Windows install program and that went fine. I'm running a very small test program :-

#include <D:\Qt\6.4.2\msvc2019_64\include\QtCore\QCoreApplication>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    return a.exec();
}

When I compile I get :-

Severity	Code	Description	Project	File	Line	Suppression State
Error	LNK1104	cannot open file 'D:\Qt\Tools\QtDesignStudio\qt6_design_studio_reduced_version\lib\Qt6Guid.lib'	QtConsoleApplication1	D:\Users\steph\Dropbox\Personal\Programming\C++\QtConsoleApplication1\QtConsoleApplication1\LINK	1

If I look for the missing file it is in fact Qt6Guid.prl instead. I've looked on here and the web and there doesn't seem to be a consensus on what this means. Any help would be most useful thanks.

@Bipman said in Prl libsfile WIndows VS C++:

#include <D:\Qt\6.4.2\msvc2019_64\include\QtCore\QCoreApplication>

What is this?
This is correct way to include this header file:

#include <QCoreApplication>

How exactly do you compile? In QtCreator?

@jsulm Ah, I've changed the include to what it should be and that works OK. I used MS VC C++ 2022 to compile the code.

I forgot to say the prl file error is still there.

@Bipman Linker tries to use wrong file: D:\Qt\Tools\QtDesignStudio\qt6_design_studio_reduced_version\lib\Qt6Guid.lib
The correct file is in your Qt installation, not QtDesignStudio.
How exactly did you install Qt?
How exactly do you build your app (in Visual Studio, in QtCreator, in terminal?)?

@jsulm Hi. I ran the Windows installer and selected the following items :-

I am compiling in MS VS c++. Everything installed correctly with no errors.
