在 g++ 编译期间未声明 [=10=]

Question

我在编译 GTK+ 应用程序时遇到错误，说我未声明 [=22=]（我相信 GTK_OBJECT 可能是头文件中的定义）。这是我的代码 (main.c)：

    #include <gtk/gtk.h>

static gint delete_event_cb(GtkWidget* w, GdkEventAny* e, gpointer data);

int main(int argc, char *argv[]) {
    //Create widgets
    GtkWidget *window;

    gtk_init(&argc, &argv); 

    //Initialize widgets
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

    //Configure widgets
    gtk_window_set_title(GTK_WINDOW(window), "Hello World");

    //Display widgets
    gtk_widget_show(window);

    //Set up signals
    gtk_signal_connect(GTK_OBJECT(window), "delete_event", GTK_SIGNAL_FUNC(delete_event_cb), NULL);

    gtk_main();
    return 0;
}

static gint delete_event_cb(GtkWidget* w, GdkEventAny* e, gpointer data) {
    gtk_main_quit();
    turn FALSE;
}

我在 bash 中使用以下命令：

g++ `pkg-config --libs --cflags gtk+-3.0` main.c -o binary

我确实安装了 gtk+ 3.0 的开发者版本。非常感谢任何帮助。

编辑：这是我收到的错误消息：

我自己解决了，但是很难找到方法。我给了 g++ 错误的参数顺序并且也错过了一个参数。这是对我有用的 bash 命令：

g++ `pkg-config --libs --cflags gtk+-3.0` main.c -o binary `pkg-config --libs gtk+-3.0`
