Linking problems



  • hi ,
    i am trying to compile an application using Qtcreator ,when the make file tries to cross compile the app using the toolchaine of the target i get the following error.

    .../arm-fsl-linux-gnueabi/bin/ld: cannot find -lpng
    ./arm-fsl-linux-gnueabi/bin/ld: cannot find -lfreetype

    i wanted to check the /arm-fsl-linux-gnueabi/bin/ld , i found that it is an executable so how can i verify their existing,? is this error linked to the toolchaine or what? i am completly lost can any one help me please, it's my first experience with qt creator

    Hi and welcome to devnet,

    Since you are cross compiling, are you sure you have these libraries installed properly ?



  • hi thanks
    the path to this ../bin/ld is an excuted file so i can't check it, i guess they are just warning
    but now i am very confused i followed the documentation of my target regarding the debloyement instruction but the app does not deploy .
    can you provide me with some tutorial on how to build and debug your application within QtCreator by selecting the build target for the remote target

    ld is the linker. It's not a warning, that message says that it can find two dependencies of your application which are the png and free type libraries. Do you have them for your target ?

    The deployment doesn't happen because your compilation fails

    What target is it by the way ?



  • i fixed that problem by adding libraries to project .thx
    my target is an arm based board

    Good !

    arm board I had guessed ;) It's the model that I wanted to know :)

    Since you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
