The library could not be configured for supporting multi-threaded applications



  • Hello,
    I am following this tutorial: http://www.appfruits.com/2015/01/compiling-qt-4-8-5-for-arietta-g25/
    I am doing this for an Berta A5 LCD board, so i replace all gnueabi by gnueabihf.

    I have this when i launch the ./Configure for ssl:

    The library could not be configured for supporting multi-threaded
    applications as the compiler options required on this system are not known.
    See file INSTALL for details if you need multi-threading.

    Because of configuration changes, you MUST do the following before
    building:
    make depend

    When i launch make depend, i have this:

    making depend in crypto...
    make[1] : on entre dans le répertoire « /home/bryan/tempdir/openssl-1.0.2h/crypto »
    ../util/domd: 31: ../util/domd: makedepend: not found
    mv: cannot stat 'Makefile.new': No such file or directory
    Makefile:136 : la recette pour la cible « local_depend » a échouée
    make[1]: *** [local_depend] Erreur 127
    make[1] : on quitte le répertoire « /home/bryan/tempdir/openssl-1.0.2h/crypto »
    Makefile:471 : la recette pour la cible « depend » a échouée
    make: *** [depend] Erreur 1

    I can continue, but when i arrive to the ./configure for Qt, i have many errors, warning and fatal errors.

    Can somebody solve my problem?

    Thanks.

    Hello,

    ../util/domd: 31: ../util/domd: makedepend: not found

    https://en.wikipedia.org/wiki/Makedepend
    It's a tool, like make, so you have to install it on your system before you're able to use it.

    Kind regards.



  • Hello,
    Thank you for your fast answer, it helps me. But i always have the warnings and the fatal errors..
    A warning :
    You have not explicitly asked to use pkg-config and are cross-compiling.

    MMX is x86 specific and not available on ARM.
    Not sure why -mmmx is passed to compiler.
    At which stage does it happen? While executing configure? If so then it is not an issue and just tells you that MMX will be disabled because not supported on the target platform. Just continue.



  • Yes, it happen when i launch the ./configure command. I tried to continue but when i launch make install, i have the following :
    Makefile:295 : la recette pour la cible « ../../lib/libQtNetwork.so.4.8.5 » a échouée
    make[1]: *** [../../lib/libQtNetwork.so.4.8.5] Erreur 1
    make[1] : on quitte le répertoire « /home/bryan/tempdir/qt-everywhere-opensource-src-4.8.5/src/network »
    Makefile:291 : la recette pour la cible « sub-network-install_subtargets-ordered » a échouée
    make: *** [sub-network-install_subtargets-ordered] Erreur 2

    May i have to continue or i have a problem ?


  • Moderators

    Correct sequence is:

    configure
    make
    make install
    

    So, after configure finished call make first.



  • Yes, that's what i've done

    What was printed before this line:

    Makefile:295 : la recette pour la cible « ../../lib/libQtNetwork.so.4.8.5 » a échouée

    Looks like you try to link dynamically against a static lib. But I don't know why that happens.



  • Don't worry, thanks for your help.
    If someone else wants to help, you are welcome !

    Where did that libssl.a binary came from? It's really strange that it's compiled as position dependent. Are you trying to build Qt statically?
