Qt giving the ld error



  • Hi ,

    Based on the url http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard

    bitbake core-image-minimal and bitbake meta-toolchain-qt5

    Both gave me success.

    But after setting the qt creator and running the example clocks code its giving me the ld errors as follows

    09:41:15: Running steps for project clocks...

    09:41:15: Configuration unchanged, skipping qmake step.

    09:41:15: Starting: "/usr/bin/make"

    collect2: error: ld returned 1 exit status

    make: *** [clocks] Error 1

    09:41:15: The process "/usr/bin/make" exited with code 2.

    Error while building/deploying project clocks (kit: wandboard)

    When executing step 'Make'

    09:41:15: Elapsed time: 00:00.

    I've assuared that the set up in the Configure Qt creators OK , but its still giving the error.

    can you suggest me for that.



  • I think you have a problem with your LIB-Path.

    The Linker tries to find the pthread-Libs in "/lib" but you are using a arm envirement, so try to find the libs for arm in your toolchane and add
    @LIBS += -L/where_your_toolchane_libs_are -lpthread....@
    in your .pro file.



  • i just included * in the .pro file but even then its throwing me thw errors as follows
