GTK+-2.0 Hello World autotools版
src/main.cpp:
#include <gtk/gtk.h> /* This is a callback function. The data arguments are ignored * in this example. More on callbacks below. */ static void hello( GtkWidget *widget, gpointer data ) { g_print ("Hello World/n"); } static gboolean delete_event( GtkWidget *widget, GdkEvent *event, gpointer data ) { /* If you return FALSE in the "delete_event" signal handler, * GTK will emit the "destroy" signal. Returning TRUE means * you don't want the window to be destroyed. * This is useful for popping up 'are you sure you want to quit?' * type dialogs. */ g_print ("delete event occurred/n"); /* Change TRUE to FALSE and the main window will be destroyed with * a "delete_event". */ return TRUE; } /* Another callback */ static void destroy( GtkWidget *widget, gpointer data ) { gtk_main_quit (); } int main( int argc, char *argv[] ) { /* GtkWidget is the storage type for widgets */ GtkWidget *window; GtkWidget *button; /* This is called in all GTK applications. Arguments are parsed * from the command line and are returned to the application. */ gtk_init (&argc, &argv); /* create a new window */ window = gtk_window_new (GTK_WINDOW_TOPLEVEL); /* When the window is given the "delete_event" signal (this is given * by the window manager, usually by the "close" option, or on the * titlebar), we ask it to call the delete_event () function * as defined above. The data passed to the callback * function is NULL and is ignored in the callback function. */ g_signal_connect (G_OBJECT (window), "delete_event", G_CALLBACK (delete_event), NULL); /* Here we connect the "destroy" event to a signal handler. * This event occurs when we call gtk_widget_destroy() on the window, * or if we return FALSE in the "delete_event" callback. */ g_signal_connect (G_OBJECT (window), "destroy", G_CALLBACK (destroy), NULL); /* Sets the border width of the window. */ gtk_container_set_border_width (GTK_CONTAINER (window), 10); /* Creates a new button with the label "Hello World". */ button = gtk_button_new_with_label ("Hello World"); /* When the button receives the "clicked" signal, it will call the * function hello() passing it NULL as its argument. The hello() * function is defined above. */ g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK (hello), NULL); /* This will cause the window to be destroyed by calling * gtk_widget_destroy(window) when "clicked". Again, the destroy * signal could come from here, or the window manager. */ g_signal_connect_swapped (G_OBJECT (button), "clicked", G_CALLBACK (gtk_widget_destroy), G_OBJECT (window)); /* This packs the button into the window (a gtk container). */ gtk_container_add (GTK_CONTAINER (window), button); /* The final step is to display this newly created widget. */ gtk_widget_show (button); /* and the window */ gtk_widget_show (window); /* All GTK applications must have a gtk_main(). Control ends here * and waits for an event to occur (like a key press or * mouse event). */ gtk_main (); return 0; }
然后使用autoscan，并 mv configure.scan configure.in
编辑configure.in：
# -*- Autoconf -*- # Process this file with autoconf to produce a configure script.
AC_PREREQ(2.61)
AC_INIT(hello, 0.1, [email protected])
AM_INIT_AUTOMAKE([hello], [0.1])
AC_CONFIG_SRCDIR([src/main.cpp])
AC_CONFIG_HEADER([config.h])
# Checks for programs.
AC_PROG_CXX
# Checks for libraries.
AM_PATH_GTK_2_0(2.0.0,,AC_MSG_ERROR( GTK+ 2.0.0 is required, but not found.))
# Checks for header files.
# Checks for typedefs, structures, and compiler characteristics.
# Checks for library functions.
AC_OUTPUT([Makefile src/Makefile])
编辑Makefile.am：
SUBDIRS=src
编辑src/Makefile.am：
bin_PROGRAMS = hello
hello_SOURCES = main.cpp
hello_CPPFLAGS = @GTK_CFLAGS@
hello_LDADD = @GTK_LIBS@
为了避免等会儿automake报错，先
touch NEWS README AUTHORS ChangeLog
然后执行
aclocal
autoconf
autoheader
automake --add-missing
其实，最困难的 ，也是我找了很久才找到的，就是AM_PATH_GTK_2_0和 src/Makefile.am中的后两行。
