Integrating two C programs

[lucks]

hi.. am working on ARToolKit which is a software library in C. i want to create an interface for it and using Gtk+ which is also in C..

when i run both programs separately, they both run well. but when i try to run my interface application through ARtoolkit,it does not work.

i`ve tried to integrate Gtk+ with ARtoolkit but am having an error called "PACKAGE"...here is what i`ve done in the ARtoolkit file that i want to run (that is i`ve added these header file from Gtk:

#include <gtk/gtk.h>
#include "interface/src/callbacks.h"
#include "interface/src/interface.h"
#include "interface/src/support.h"
#include "interface/msvc/config.h"

i think am not doing the correct way of integration.if anyone can help me please

any help will be highly appreciated

thanks

Does your C compiler have an option to print all the include files that the compiler is accessing? If it does, switch it on: at least that will tell you what has been included so far and where there error is coming from.

If that doesn't give you any clues, could you post the exact error message. Just telling us that it is an error called "PACKAGE" doesn't give any clues.

hi xwb,

my compiler does not have the option to print the include files but we can see all the files in the same window that we are working..

here is my code for ARtookit (C program):

well am trying to call the main from another program (Gtk) and i`ve comment it above...

here is the main file of the program (Gtk) which i want to call:

PACKET is probably in the definition or ARParam. Possibly a macro. May be an include file problem. What I'd do is

1) go to the include directory and grep (if you're using Windows, findstr) for PACKET in the AR header files.
2) Make sure the header that defines it in included
