Qt+boost+Wt = problems...

ThaRez

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

ld: symbol(s) not found for architecture x86_64

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.
