一)Ubuntu 下 Gtk2.0 的安装
1、首先当然了，要确保安装了build-essential
sudo apt-get install build-essential
2、然后，输入命令：sudo apt-get install libgtk2.0-dev
可以再安装Gtk的开发手册 sudo apt-get install devhelp
#include<gtk/gtk.h>void hello(GtkWidget *widget,gpointer data){g_print(“Hello Ubuntu!\n”);}gint delete_event(GtkWidget *widget,GdkEvent *event,gpointer data){g_print (“delete event occurred\n”);return(TRUE);}void destroy(GtkWidget *widget,gpointer data){gtk_main_quit();}int main( int argc, char *argv[] ){GtkWidget *window;GtkWidget *button;gtk_init (&argc, &argv);window=gtk_window_new (GTK_WINDOW_TOPLEVEL);gtk_signal_connect (GTK_OBJECT(window),”delete_event”,GTK_SIGNAL_FUNC(delete_event),NULL);gtk_signal_connect (GTK_OBJECT (window), “destroy”,GTK_SIGNAL_FUNC (destroy), NULL);gtk_container_set_border_width (GTK_CONTAINER (window), 10);button = gtk_button_new_with_label (“Hello Ubuntu!,\nI am Waynebuaa”);gtk_signal_connect (GTK_OBJECT (button), “clicked”,GTK_SIGNAL_FUNC (hello), NULL);gtk_signal_connect_object (GTK_OBJECT (button), “clicked”,GTK_SIGNAL_FUNC (gtk_widget_destroy),GTK_OBJECT (window));gtk_container_add (GTK_CONTAINER (window), button);gtk_widget_show (button);gtk_widget_show (window); /*显示一个窗口*/gtk_main(); /*进入主循环*/return(0);}
二） Qt的编译安装
下载 qt-everywhere-opensource-src-4.7.2，不编译demos和examples，，以节省时间：
./configure -release -nomake demos -nomake examples
make
有时我们选择改变，并非经过深思熟虑，而更像是听见了天地间冥冥中的呼唤，
