    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.

      Hi,

      I tried to link the cppunit library dynamically but still getting the same error as follows

      cmUdp.o: In function cCmUdp::cmUdpSocketInit(CM_UDPSOCKET_HANDLE*, HA_UDP_PARAM*)': /home/mistral/Desktop/QT Projects/cppunittest_gui/cmUdp.cpp:73: undefined reference to QDebug::~QDebug()'

      When I include the cppunit as a static library I am getting the output as follows

      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.

      Read and abide by the Qt Code of Conduct

        Hi,

        Regarding the version , I am using version 5.5.1 of Qt and cpp unit version is 1.12.1
        Regarding the linking step please find the complete compiler output as mentioned below.

          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 here cmUdp.cpp:73 in 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 ?

                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 here cmUdp.cpp:73 in 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.

                @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

                  Did you also installed Qt from your distribution ?

                  @SGaist just saw your post. I am thinking the same

                    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?

                          Could you check if you have libQt5*.so in any other place than /home/mistral/Qt/5.5/gcc_64/lib

                            This thread got really confusing.

                            @asanka424
                            I'm not linking anything, it's in fact Ayush who's having trouble.

                            @ayush_mistral
                            Make sure you're running the qmake that came with the package you installed, and not a system-wide installed one. That's what's @SGaist was implying with his question, however it seems you do indeed. /home/mistral/Qt/5.5/gcc_64/bin/uic this looks exactly as I'd expect. I don't think your problem is related to the cpp unit library as I mentioned before. Besides running qmake again to recreate the project I'm running out of ideas ...

                            Kind regards.

                                Okay, then this: "Make sure you're running the qmake that came with the package you installed, and not a system-wide installed one." is quite relevant.
                                Use the qmake that came with the package you installed. You can find it somewhere in the /home/mistral/Qt/.../bin folder. You go to your project, run make clean, then use the correct qmake to create the Makefile anew, and then you make your project again.

                                Kind regards.

                                  Hi I found the qmake executable in the path Qt5.5/gcc_64/bin folder

                                  Can you please tell me which tab should I change in qt projects tab to provide the path for the appropriate qmake?

                                    Actually you set up a kit for QtCreator and then change the kit for your project. To make your kit work with the Qt you've downloaded just specify the correct qmake executable and a name that you'd recognize.
                                    The kit your project uses is on the projects page, up-most, just below the name of the project. You have the kit name there and under it two buttons - build and run. Pointing at the kit name ("Qt 5.6 64 bit" in my case) will cause a down arrow to show next to the text. Clicking the arrow there's a context menu that has Change kit on it, and you just select the one you like. After changing the kit, do a full rebuild of your project.

                                    Kind regards.

                                      I have the following settings in the newly created kit

                                      Name- cppunit_qt
                                      Device type - desktop
                                      Device - Local PC
                                      Compiler - GCC (x86 64bit in /usr/bin)
                                      Debugger - System GDB at /usr/bin/gdb

                                      Try to make clean and rebuild the project still the error is the same
                                      Can you please tell me if I am missing something or doing something wrong?

                                      Thanks and Regards
