newbie xhello.c question


(apologies if this is a duplicate post - I originally posted at 11:30 AM,
and
haven't seen it come thru yet)

I've just downloaded cygwin and am trying to get an Xwidget hello program
to compile + run.

With the following Imakefile and xhello.c, I get the following when I do
"xmkmf", "make".   Is there something I haven't set up?

$ make
gcc   xhello.o      -o xhello
xhello.o(.text+0x65):xhello.c: undefined reference to `_XtVaAppInitialize'
xhello.o(.text+0x70):xhello.c: undefined reference to `_labelWidgetClass'
xhello.o(.text+0x88):xhello.c: undefined reference to
`_XtVaCreateManagedWidget'
xhello.o(.text+0x90):xhello.c: undefined reference to `_XtRealizeWidget'
xhello.o(.text+0x9b):xhello.c: undefined reference to `_XtAppMainLoop'
collect2: ld returned 1 exit status
make: *** [xhello] Error 1

LOCAL_LIBRARIES = $(XAWLIB) $(XMULIB) $(XTOOLLIB) $(XLIB)

       PROGRAMS = xhello
