gnome hello world 编译

#include <gnome.h>

#define VERSION "1.0"

/* "callback" function (signal handler) which will quit the application*/

static void exit_hello(GtkWidget *widget, gpointer data)
{
    gtk_main_quit ();
}

/* callback function for when the window closes */
static int delete_event(GtkWidget *widget, gpointer data)
{
    gtk_main_quit();
    return FALSE; /* false means continue with closing the window */
}

int main(int argc, char *argv[])
{
    GtkWidget *app; /* pointer to our main window */
    GtkWidget *w;
   
    /* initialize gnome */
    gnome_init("hello_world", VERSION, argc, argv);

    /*create main window*/
    app = gnome_app_new("hello_world", "Hello World (Gnome Edition)");
   
    /* connect "delete_event" (happens when the window is closed */
    gtk_signal_connect(GTK_OBJECT(app), "delete_event",
                       GTK_SIGNAL_FUNC(delete_event), NULL);

   /* show all the widgets on the main window and the window itself */
    gtk_widget_show_all(app);

    /* run the main loop */
    gtk_main();   

    return 0;
}

编译的时候按照网上提供的Makefile

CFLAGS=-g -Wall `gnome-config --cflags gnome gnomeui`
  LDFLAGS=`gnome-config --libs gnome gnomeui`
  all: hello_world
  clean:
    rm -f hello_world core

编译失败

原因是在ubuntu 下面 gnome-config 被 pkg-config取代了
gnome gnomeui 被 libgnome-2.0 libgnomeui-2.0 取代

所以Makefile改成：

all: hello
GCC=gcc
FILE=hello

CFLAGS+=$(shell pkg-config --cflags libgnomeui-2.0 gtk+-2.0)
LIBS+=$(shell pkg-config --libs libgnomeui-2.0 gtk+-2.0)


.c.o:  
	$(GCC) -c $< $(CFLAGS)  
   
$(FILE).o: $(FILE).c      
 
hello: $(FILE).o  
	$(GCC) -o hello $(FILE).o $(CFLAGS) $(LIBS)  
   
   
clean:  
	-rm hello *.o
