Undefined symbol: 'class CRepository * CRepository::NewLC(class TUid)

[duwaji]

Hi,

I am using Qt with standalone Symbian^3 sdk 0.9 and Carbide.c++. I am trying to use the centralrepository in my application using the following code:

#include "test001.h"
#include <centralrepository.h>
#include <dclcrkeys.h> 

test001::test001(QWidget *parent)
    : QMainWindow(parent)
{
	ui.setupUi(this);
	
	CRepository* cRepository = CRepository::NewLC( KCRUidDCLLogs );
}

but I am getting this error:

1291630582885 Undefined symbol: 'class CRepository * CRepository::NewLC(class TUid) (?NewLC@CRepository@@SAPAV1@VTUid@@@Z)' test001 Unknown C/C++ Problem

Can somebody offer some help? Do I need a plug in for this? Thanks
I followed the instructions in this page to set up my environment. I am using ActivePerl-5.8.9.827-MSWin32-x86-291969.

You have to add the library to your project. I think you will find some libraries in the .pro file already, list centralrepository.lib amongst them.

Note that there are Qt boards on this site, I have started to move some of your threads there. You can find the Qt boards if you scroll the discussion main page (http://discussion.forum.nokia.com) a bit downwards.

Hi Wizard,

I do have centralrepository added in my .pro file. Any other reason you can think of?

Thanks

The symbol exists, you can find it in C:\Nokia\devices\Nokia_Symbian3_SDK_v0.9\epoc32\release\winscw\udeb\centralrepository.lib with a file viewer. But I do not know what you should take care of in case of modifying and re-building a Qt, that is why the thread is moved here.

You probably need a library (added to your LIBS statement in the .pro file).

Try "LIBS += -lcentralrepository".

Thanks. That fixed the problem.

I had LIBS += centralrepository and when I changed it to LIBS += -lcentralrepository the problem is fixed.

Thanks

Yeah, the reason is lost in the mists of history, but lib/dll files need to be prefixed with "-l". Library directories are prefixed with "-L". And, oddly, you put no suffix on the lib file name, but if it's a dll instead you suffix it with ".lib".
