Your code is calling several functions that are not part of the standard
C library. You must provide a library which contains those funcitons.

You asked this in on c.l.c 2006, the same answers apply.

It would be better to write
#include <X11/Xlib.h>
#include <X11/Xutil.h>

then, probably something like the following, assuming your
lib files are in /usr/openwin/lib (e.g. libXlib.a if it's
the correct name for your library)
cc -I/usr/openwin/share/include -L/usr/openwin/lib -lXlib -lXutil

The problem that I do not know what library files should be included
to resolve these functions
so I compiled with the below errors :

#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <stdio.h>
#include <math.h>

int n = 0;

How did you resolve them in 2006?

Are you sure you want "-I/usr/openwin/share/include" instead of
"-L/usr/openwin/share/include" ?

Where are libX11.aand libXutil.a on your system?

In my experience, Sun Unix platforms put them in "/usr/openwin",
while most other -nix platforms put them (or at least links to them)
in /usr/lib or /usr/X11R6.

You need to find where thosw libraries are on your system, and
set the "-L" options appropriately to point to them.

> create_int_dialog_entry

Line 15 of your source code apparently references a function
named "create_int_directory_entry" without you having provided
a prototype for that function.

Ditto for these warnings.

libXlib.a and libXutil.a could not be found in the paths you provided.

It looks like something is wrong : did you check the "implicitly
declared" function are really in those header files ? Did you check
the lib file are really in this directory ?
