Gcc problem on FC6

I am having a simple problem: I want to compile a relatively simple
gui example program. This code is off the net, and appears correct, yet
I cannot get it to compile and link.
The errors are:
make -k GuiExample
g++ GuiExample.cpp -o GuiExample
/tmp/cc2fblEI.o: In function `main':
GuiExample.cpp:(.text+0x1e): undefined reference to `XOpenDisplay'
GuiExample.cpp:(.text+0x102): undefined reference to
GuiExample.cpp:(.text+0x11f): undefined reference to `XSelectInput'

GuiExample.cpp:(.text+0x1cf): undefined reference to `XFlush'
collect2: ld returned 1 exit status
make: *** [GuiExample] Error 1
The include appears to be correct for these routines. The routines are
defined in Xlib.h, and the C preprocessor shows the header finds the
library (cpp -H shows /usr/include/X11/Xlib.h being located).
I have also tried using the basic make -k with the same results (no
surprise). So the question is, if the header is found and cpp works,
then I suspect either link or ld as the culprits, but that would mean
that the standard loader execution is messed up, because it should look
in /usr/lib for the associated ".a" files that match the headers. When
I look in /lib/X11, the only file there is the error message database.
What happened to the X libraries?
Help me Mr. Bill (or anyone else who has the answer)!!! With appologies
to Gumby and his creator Art Clokey.
