Qt+boost+Wt = problems...



  • Hello
    I've struggled to get Wt with Qt and so far I've managed to install the boost libraries and Wt.
    But when I try compile a Qt project in QtCreator (or terminal), it fails. With the following errors:

    Richard-Salins-MacBook-Pro:wtex richardsalin$ make
    g++ -headerpad_max_install_names -arch x86_64 -Xarch_x86_64 -mmacosx-version-min=10.5 -o CppWtMenu main.o menuapplication.o menuwidget.o -F/Users/richardsalin/QtSDK/Desktop/Qt/473/gcc/lib -L/Users/richardsalin/QtSDK/Desktop/Qt/473/gcc/lib -lwt -lwthttp -framework QtCore
    Undefined symbols for architecture x86_64:
    "boost::signals::connection::~connection()", referenced from:
    MenuWidget::MenuWidget()in menuwidget.o
    MenuWidget::MenuWidget()in menuwidget.o
    boost::signals::detail::slot_base::data_t::~data_t()in menuwidget.o
    "boost::signals::detail::slot_base::create_connection()", referenced from:

    ld: symbol(s) not found for architecture x86_64
    collect2: ld returned 1 exit status

    The example is a direct copy paste from: http://www.richelbilderbeek.nl/CppWtExample1.htm.
    I'd really like to add capabilites provided by Wt to my Qt project, but currently I'm stuck. I'm using a Mac osx Lion platform. I'd really appreciate any assistance. Thank you!
    Best regards
    Richard



  • Have you add following line

    @
    CONFIG += no_keywords
    @

    to your XXX.pro file?



  • ...no, but unfortunately it didn't help. :( Thanks anyway. Still open for further suggestions.

    ps. This is my pro file in use (a direct example copy/paste + "no_keywords"):

    @QT += core
    QT -= gui
    LIBS += -lwt -lwthttp

    QMAKE_CXXFLAGS += -DNDEBUG

    TARGET = CppWtMenu
    CONFIG += console
    CONFIG -= app_bundle
    CONFIG += no_keywords
    TEMPLATE = app

    SOURCES += main.cpp
    menuapplication.cpp
    menuwidget.cpp

    HEADERS +=
    menuapplication.h
    menuwidget.h@



  • For what architecture did you build the boost an Wt libraries? The universal binaries must at least contain every architecture you build your application for.
