linking error in qt3 program

[gilles.degottex]

Hi hi

	I did a qt3 program under rh8 linux, everything goes fine, compiling 
runing, etc ...
	then I try to compile it under cygwin because, like you surely know, 
qt3 is not available for Visual Studio 6.

	here are the commands:

uic gui/form.ui -o gui/form.h
uic gui/inform.ui -o gui/inform.h
uic gui/AboutDialog.ui -o gui/AboutDialog.h
c++ -I/lib/qt3/include  -o obj/main.o -c main.cpp
c++ -I/lib/qt3/include  -o obj/FormCustom.o -c FormCustom.cpp
...
moc gui/AboutDialog.h -o gui/moc_AboutDialog.cpp
c++ -I/lib/qt3/include  -o obj/moc_AboutDialog.o -c gui/moc_AboutDialog.cpp
c++ -I/lib/qt3/include  -o obj/Ordinapoche.o -c Ordinapoche.cpp
c++ -L/lib/qt3/lib -lqt obj/main.o obj/FormCustom.o obj/form.o 
obj/moc_form.o obj/inform.o obj/moc_inform.o obj/AboutDialog.o 
obj/moc_AboutDialog.o obj/Ordinapoche.o -o Ordp

	and at linking step I get a lot of:

obj/main.o(.text+0xc2):main.cpp: undefined reference to 
'QApplication::QApplication[in-charge](int&, char**, bool)'
obj/main.o(.text+0xea):main.cpp: undefined reference to 
'QString::operator=(char const*)'
...
obj/FormCustom.o(.data$_ZTV10FormCustom+0xf0):FormCustom.cpp: undefined 
reference to 'QMainWindow::sizeHint() const'


thanks for all :)
