QT 5 compile fails with undefined symbols for x86_64 on OS X



  • I having an issue compiling QT 5.0, where it eventually errors out due to undefined symbols for x86_64.


    Undefined symbols for architecture x86_64:
    "_XSetErrorHandler", referenced from:
    QGtkStylePrivate::initGtkWidgets() const in qgtkstyle_p.o
    "_XSetTransientForHint", referenced from:
    QGtkStylePrivate::setupGtkFileChooser(_GtkWidget*, QWidget*, QString const&, QString const&, QString*, QFlagsQFileDialog::Option, bool, QHash<_GtkFileFilter*, QString>*) in qgtkstyle_p.o
    ld: symbol(s) not found for architecture x86_64

    Anyone see this before?

    Compiling previous versions of QT don't have this issue.

    Did not get this particular one. Occasionally, though, symbols not found does happen due to Apple's shamefully outdated tools and qmake's archaic macx-xcode specs.

    Several things that might help:

    • which version of Mac OS, Xcode do you have?
    • change the mkspecs to macx-llvm (in configure, that's -platform macx-llvm, in qmake: -spec macx-xcode)
    • force Mac to use g++ as linker (Apple's ln is a bit flawed ere and there)
    • pass -no-gtkstyle to configure


  • i'm running OS X 10.8.2 and Xcode 4.5.2.

    I'd be interested to know how others with this configuration have successfully compiled QT 5.0.
