hi
i m using KDE3 and QT3.3.4

i want to use a KDE button which is provided in the QT-Designer menu. When i add this button to a form and compile, it gives an error:

[localhost test]$ make
g++ -o test .obj/main.o .obj/frm_main.o .obj/qmake_image_collection.o .obj/moc_frm_main.o -L/usr/lib/qt-3.3/lib -L/usr/X11R6/lib -lqt-mt -lXext -lX11 -lm
.obj/frm_main.o(.text+0x1a6): In function `frm_main::frm_main(QWidget*, char const*, unsigned int)':
.ui/frm_main.cpp:38: undefined reference to `KKeyButton::KKeyButton(QWidget*, char const*)'
.obj/frm_main.o(.text+0x312): In function `frm_main::frm_main(QWidget*, char const*, unsigned int)':
.ui/frm_main.cpp:38: undefined reference to `KKeyButton::KKeyButton(QWidget*, char const*)'
collect2: ld returned 1 exit status
make: *** [test] Error 1

I know that this is some linking problem. How to solve it?Please help...
Where and how should i add this KDE include dir information.
My KDE header files are in '/usr/include/kde/'

Thanks...
