如何在代码块中设置GTk 2

Question

I want to setup gtk2 and i did:

compiler option:pkg-config --cflags gtk+-2.0
likker option:pkg-config --libs gtk+-2.0

I added the path gtk2 to variable path and add gdk-pixbuff to a user variable but when i compile the code below;

#include <gtk/gtk.h>


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

  GtkWidget *window;
  GtkWidget *vbox;

  GtkWidget *menubar;
  GtkWidget *filemenu;
  GtkWidget *file;
  GtkWidget *quit;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
  gtk_window_set_default_size(GTK_WINDOW(window), 250, 200);
  gtk_window_set_title(GTK_WINDOW(window), "menu");

  vbox = gtk_vbox_new(FALSE, 0);
  gtk_container_add(GTK_CONTAINER(window), vbox);

  menubar = gtk_menu_bar_new();
  filemenu = gtk_menu_new();

  file = gtk_menu_item_new_with_label("File");
  quit = gtk_menu_item_new_with_label("Quit");

  gtk_menu_item_set_submenu(GTK_MENU_ITEM(file), filemenu);
  gtk_menu_shell_append(GTK_MENU_SHELL(filemenu), quit);
  gtk_menu_shell_append(GTK_MENU_SHELL(menubar), file);
  gtk_box_pack_start(GTK_BOX(vbox), menubar, FALSE, FALSE, 3);

  g_signal_connect_swapped(G_OBJECT(window), "destroy",
        G_CALLBACK(gtk_main_quit), NULL);

  g_signal_connect(G_OBJECT(quit), "activate",
        G_CALLBACK(gtk_main_quit), NULL);

  gtk_widget_show_all(window);

  gtk_main();

  return 0;
}

I am very upset and confused? How do I solve this problem?

Answer 1

To compile a GTK+ application, you need to tell the compiler where to find the GTK+ header files and libraries. This is done with the pkg-config utility.

for header file you need to add below build option in codeblock option.

 pkg-config --cflags gtk+-3.0

for library you need to add below build option in codeblock option.

 pkg-config --libs gtk+-3.0

Please go through it would help you.

my problem was that i used gtk x64 ,but codeblock work with gtk x86

now i use gtkx86 and codeblock x86 it works nice. some times there is now errors,only we is confused...
