GTK+-2.0 Hello World autotools版


src/main.cpp:
#include /* 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; }
 
次にautoscanを使用し、mv configure.scan configure.in
 
configureを編集します.in:
#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.

AC_OUTPUT([Makefile src/Makefile])

Makefile.の編集am:
SUBDIRS=src

src/Makefileを編集します.am:
bin_PROGRAMS = hello
hello_SOURCES = main.cpp
hello_CPPFLAGS = @GTK_CFLAGS@
hello_LDADD = @GTK_LIBS@


あとでautomakeが間違ったことを報告しないように、まず
touch NEWS README AUTHORS ChangeLog
そして実行
aclocal
autoconf
autoheader
automake --add-missing

 
実は、一番難しいのは、私が長い間探してやっと見つけたのです.AMです.PATH_GTK_2_0とsrc/Makefile.amの後ろの2行.
