multiple definition error

[Robert Wimmer]

hi,

i am c++ newbie. i wrote a view tools for using X11 in c and they compiled 
well. but now i have rewritten some of these modules in c++ (only the tool 
using x11 primitives is still in c) and compiling them i always get  errors 
like this

***************************
gcc   -o style style.cpp X_TOOL.o X_STYLE.o -L/usr/X11R6/lib -lm -lX11
X_STYLE.o(.bss+0x10): multiple definition of `X_Blue'
/tmp/ccjmheIq.o(.bss+0x10): first defined here
X_STYLE.o(.bss+0x8): multiple definition of `X_Red'
/tmp/ccjmheIq.o(.bss+0x8): first defined here
**************************
this is my makefile

************************** stylemake *******************

style           :       X_STYLE.o X_TOOL.o style.o
                        gcc   -o style X_TOOL.o X_STYLE.o style.o 
-L/usr/X11R6/lib -lm -lX11

style.o         :       style.cpp X_STYLE.h
                        gcc -c -Wall style.cpp

X_STYLE.o       :       X_STYLE.cpp   X_STYLE.h
                        gcc -c -Wall  X_STYLE.cpp

X_TOOL.o        :       X_TOOL.c X_TOOL.h
                        gcc  -c -Wall X_TOOL.c -I/usr/X11R6/include

********************* eof ********************************


i always use the

#ifndef ....
  # define ....
....
# endif

statement at the beginning of  my haeder files, and also the extern "C" 
command for including the tool written in c.

*************************** top of X_STYLE.h ***********************

# ifndef _X_STYLE_H
  # define _X_STYLE_H

extern "C"
  {
  # include "X_TOOL.h" // X_TOOL.h starts with : ifndef X_TOOL_H define ...
  }

typedef enum { LEFT, CENTER, RIGHT } X_STYLE_HALIGN;
typedef enum { TOP, MIDDLE, BOTTOM } X_STYLE_VALIGN;
typedef struct { int   left,top,bottom,right; } X_STYLE_Margin;
typedef struct { X_Pixel left,top,bottom,right; } X_STYLE_BorderColor;

class X_Style {

  private :

  char                  *name;
  X_STYLE_Margin        margin,
                        border,
                        padding;
  X_Pixel               color,
                        bgcolor;
  X_STYLE_BorderColor   bordercolor;
  X_STYLE_HALIGN        halign;
  X_STYLE_VALIGN        valign;
  X_Font                *font;
