QtMobility header not found on Mac OS X

  • Hello. I am trying to install QtMobility on Mac OS X. I need only the systeminfo module, so I do the following:

    ./configure -modules systeminfo -prefix /usr/local/QtMobility
    make install

    I see QtSystemInfo.framework installed, but when I try to build quickstart sample, it can't find QSystemInfo header. Also I see Xcode doesn't add QtSystemInfo.framework to the project. Even if I drag it manually, it is shown in red color like a missing file. Installation guide tells I have to expand LD_LIBRARY_PATH variable, so I tried to add the following to /etc/profile:

    export LD_LIBRARY_PATH

    Also tried to expand DYLD_LIBRARY_PATH instead. Nothing works.

    I've tried it on different Mac OS X versions (10.6 and 10.7) with no success. What should I do in order to make QtMobility available for my projects?

  • Have you tried using Qt Creator? According to "Qt Mobility 1.2.2 documentation XCode is not supported":

    bq. Note: QtMobility currently has no support for building with Xcode.

  • I have tried to build it from the command line:
    qmake -spec macx-g++

    It fails with the same error. I will try Qt Creator, but I scarcely believe it depends on IDE. As far as I understand, they meant building QtMobility framework with Xcode is not supported - I don't do that. Xcode is used to build a project that uses QtSystemInfo.framework.

    Could you please post the whole error log?

  • Please make sure that your pro file includes the following configuration:

    CONFIG += mobility
    MOBILITY = systeminfo

    And specify Qt Mobility namespace:
    #include <QSystemInfo>


    If this doesn't then most probably Qt Mobility is not installed successfully. You can check other threads in "Qt Project's forum for similar issues and hints for settings DYLD_LIBRARY_PATH on Mac OS":

  • Yes, it does include

    @CONFIG += mobility

    MOBILITY = systeminfo@

    Moreover, it is a sample project shipped along with QtMobility that shows the proper basic usage of QtMobility framework.

    I didn't see any error messages while installing QtMobility. Only while configuring it failed to find something, but it didn't seem to be needed for systeminfo module, so it succeeded to build. I have it installed in the desired location, only it is not visible to my project. I see LD_LIBRARY_PATH and DYLD_LIBRARY_PATH extend the library paths, but my issue is about headers. So I need to find a way to make headers available. Documentation simply keeps silence about it :(
