Hi
Is there a way to attach files?
Anyway, here is my current code:

}
My Qt Creator project file:
#-------------------------------------------------
#
# Project created by QtCreator 2011-04-05T12:51:44
#
#-------------------------------------------------
QT += core gui
TARGET = LekeLand
TEMPLATE = app
SOURCES += main.cpp\
widget.cpp \
QSFMLCanvas.cpp
HEADERS += widget.h \
QSFMLCanvas.h
FORMS += widget.ui
INCLUDEPATH += /home/agrualon/SFML-2.0-build/include
LIBS += /home/agrualon/SFML-2.0-build/lib/libsfml-system.so \
/home/agrualon/SFML-2.0-build/lib/libsfml-window.so \
/home/agrualon/SFML-2.0-build/lib/libsfml-graphics.so \
/home/agrualon/SFML-2.0-build/lib/libsfml-audio.so \
/home/agrualon/SFML-2.0-build/lib/libsfml-network.so
The problem is that when I build it, it returns:
collect2: id returned 1 exit status
Nothing more..
I created the project using Qt Creator, File -> New File or Project -> Qt C++ Project. In the wizard I selected QWidget as my base-class..
Any halp?
