But that is so far I can get most approach to X on linux, which is I borrow from Los Angeles's central city library at downtown.  I also see another book, "Motif", in that library also doing graphic on Unix, written by c++.  I search a little bit on google's motif part, i find a simple c code and I copy it and try to compile it on my system, but it not work

Here's your (first) problem.  You need to install the development
package for motif as well (probably libmotif-dev).  (Also, you should
place -lXm before -lXt on the command line, and you can probably drop

But really, take Alan's advice and start looking at Qt or Gtk instead.
They are much easier to program, and are generally better in every way.
