Undefined reference to qDebug
-
Yes it was building before adding the cppunit library and header in the .pro file.
Please find my .pro file as below.
Thanks

@ttuna I used qdebug() for printing debug messages like below mentioned example
qDebug() << "Socket Bounded";

Hi,
Maybe a silly question but did you
#include <QtDebug>in your cpp file ? -
Hi,
I want to use test a QT Desktop GUI application project using CppUnit Framework.
When I included the CppUnit Library path and the headers in the .pro file of the QT Project and build the project I am getting compiler error messages as "undefined reference to qDebug" . For example like this :
/cmUdp.cpp:72: error: undefined reference to `QDebug::~QDebug()'.
I included the Qdebug header in the source file,(#include <QDebug>) but still showing the error.Please help me to know what may be the probable cause of this error and what is the possible solution.
Thanks in advance

Hello,
Do you mind putting the whole compilation window content somewhere for us to see (it may be long so perhaps uploading it to a site and linking it here is a good idea)?
In the meantime, could you try linking the CppUnit Framework dynamically and let us know how it goes?Kind regards.
-
Hi,
I did #include <QtDebug> in my .cpp file but still its showing the same error as
/QT Projects/cppunittest_gui/cmUdp.cpp:73: error: undefined reference to `QDebug::~QDebug()'Thanks and Regards

Ayush -
The linking information is missing. That's needed in order to see whether the correct version of Qt is linked to your application.

Hello,
Getting the same error would mean that your problem shouldn't be related to the library itself, however I second @SGaist's note, you've not provided the linking step, only the errors. I'd suggest finding where the linker runs and allow for us to see what's done at that particular point.Kind regards.

At a first glance it looks okay, maybe @SGaist will spot something suspicious, I don't see anything out of the ordinary. What do you have herecmUdp.cpp:73in your source (+- a couple of lines)? In principle the linker shouldn't be complaining about the destructor. Where does your Qt come from, have you built it yourself or you've installed it from the Qt site? Are you sure the compiler/linker used for building Qt matches the one you're using (although it seem you are)?Kind regards.

Hi,
I download the QT version for linux from the Qt website only and for compiling and building my application I am using Qt creator IDE.
Thanks and Regards

Did you also installed Qt from your distribution ?

@kshegunov you are linking with wrong libraries. You might have installed Qt from your package manager. So its linking with your program since linker is finding that before the actual libraries. If you are using Qt Creator go to projects tab and chanch path variable. Or uninstall Qt installed using your package manager

I'm still at beginner's crawling stage ..
but I do spot a space in your path .. /QT Projects/
I've learned to purge all spaces in my projects under development .. e.g. /Qt_Projects/
May not be relevant to your problem but worth remembering. -
I am not getting clearly. I download my qt set up from qt website and use the same script for installation.
Thanks and Regards

Hi,
I didn't install QT from package manager but ran the executable from the set up which I obtained/downloaded from the QT website.
Secondly I am also using Google test framework for testing my project but that is not causing any problem.
I want to know why including cpp unit library and headers in the .pro file is causing the linking error?
