Hi guys, I am new to programming on linux, and I am having problems getting my first attempt at an app to compile. although I already have the lib-gtk2.0 library installed I keep getting this error when trying to compile my main.c file.

Here is the error I'm receiving...
"main.c:10:21: error: gtk/gtk.h: No such file or directory"

And here is what I have in my main...

 c Syntax (Toggle Plain Text) 
#ifdef HAVE_CONFIG_H
#  include <config.h>
#endif
 
#include <gtk/gtk.h>
 
#include "interface.h"
#include "support.h"
 
int
main (int argc, char *argv[])
{
  GtkWidget *BuddySelector;
 
#ifdef ENABLE_NLS
  bindtextdomain (GETTEXT_PACKAGE, PACKAGE_LOCALE_DIR);
  bind_textdomain_codeset (GETTEXT_PACKAGE, "UTF-8");
  textdomain (GETTEXT_PACKAGE);
#endif
 
  gtk_set_locale ();
  gtk_init (&argc, &argv);
 
  add_pixmap_directory (PACKAGE_DATA_DIR "/" PACKAGE "/pixmaps");
 
  BuddySelector = create_BuddySelector ();
  gtk_widget_show (BuddySelector);
 
  gtk_main ();
  return 0;
}
#ifdef HAVE_CONFIG_H
#  include <config.h>
#endif

#include <gtk/gtk.h>

#include "interface.h"
#include "support.h"

int
main (int argc, char *argv[])
{
  GtkWidget *BuddySelector;

#ifdef ENABLE_NLS
  bindtextdomain (GETTEXT_PACKAGE, PACKAGE_LOCALE_DIR);
  bind_textdomain_codeset (GETTEXT_PACKAGE, "UTF-8");
  textdomain (GETTEXT_PACKAGE);
#endif

  gtk_set_locale ();
  gtk_init (&argc, &argv);

  add_pixmap_directory (PACKAGE_DATA_DIR "/" PACKAGE "/pixmaps");

  BuddySelector = create_BuddySelector ();
  gtk_widget_show (BuddySelector);

  gtk_main ();
  return 0;
}

This of course is all generated by Glade so I'm assuming I am just missing some package or something?

thanks for taking a look at this for me.

btw: in case someone was curious, I'm working on a pidgin plugin, there was this plug-in called sendtosome in gaim that i really loved but it doesn't exist in pidgin so I decided to make it myself.

What's your compilation command line?

melbolt · Aug 17th, 2007, 9:30 AM

If I recall correctly, I tried using both "gcc main.c" and "make main" and received the same error on both.

you need to use pkg-config for gcc to find the headers:

(Toggle Plain Text)

gcc `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0` main.c -o main

First pkg-config invocation gets the required compiler flags to find includes and whatnot, second tells it where to find the libraries to link against and which ones to use. the `` tells the shell to insert the output of the command inside at that location.

ah ok, I get what you're saying, using what you gave me and a bit more research, I managed to get it past the includes. There were other errors I received later but then I found a tutorial on glade and how you are supposed to run the autogen.sh executable file and then you are able to use a "make" command and it successfully spits out an executable file which will then launch the program created in the glade designer.

This works all well and good, I have my form with controls on it and callbacks handling what I need, the app runs great.

Here is my dilemma that maybe someone here can help me with...

I don't want what I created in glade to be built into an executable, I need it to be built into a .so file. The reason why is because, as I mentioned in a previous post, this is going to be a plug-in for the pidgin messenger client and in order to use it as a plug-in it must be built into a .so not an executable.

I know I could go the long way and not use glade to do all the form coding for me, but I'd rather not if I can avoid it, does anyone know a way to do this?

thanks a lot for the help.

sorry, to be more specific and to the point, I want glade to output a dynamic library or shared library. any idea how to do that?
