一步一步搭建GTK-DFB开发环境

0. 概要

    GTK-DFB环境存在于GDK库中，它整合了GTK+工具集和DirectFB视窗系统，就像GTK-X11整合了GTK和X11，GDK-WIN32也起到了Windows GDI一样的作用。GTK-DFB主要面向嵌入式应用程序，而不是桌面应用程序。它不具备像X11或者GDK-WIN32那样全面的功能，却也足够开发复杂的应用程序，比如Linux下的画图工具GIMP。

    下面主要介绍GTK-DFB开发环境的搭建。

※注意：

这里可以将GTKDFB安装到/usr/local/dfb目录下面，以免和系统中已经存在的X11和DFB应用程序相冲突。GTKDFB的运行依赖于以下开发库：

jpeg libpngpkg-config gettextglib atk freetype DirectFB

libexpat fontconfig pixmancairopangogtk libIDL

※准备：

需要创建以下目录

• mkdir /usr/local/dfb
• mkdir -p /usr/local/dfb/man/man1
• mkdir /usr/local/dfb/bin
• mkdir /usr/local/dfb/lib
• mkdir /usr/local/dfb/etc
• mkdir /usr/local/dfb/include
• mkdir /usr/local/dfb/info
• mkdir /usr/local/dfb/sbin
• mkdir /usr/local/dfb/share
• mkdir /usr/local/dfb/src

在终端设置以下的环境变量，也可以写成脚本文件，如/root/export.sh

#!/bin/bash

exportLD_LIBRARY_PATH=/usr/local/dfb/lib

exportPATH=/usr/local/dfb/bin/:$PATH

exportPKG_CONFIG_PATH=/usr/local/dfb/lib/pkgconfig

每次打开终端只需执行

#source /root/export.sh

2．测试GTK-DFB环境

    首先设置环境变量，如果之前写好了脚本export.sh 可以在终端直接执行：

#source export.sh

或者一步一步执行：

#exportLD_LIBRARY_PATH=/usr/local/dfb/lib

#exportPATH=/usr/local/dfb/bin/:$PATH

#export PKG_CONFIG_PATH=/usr/local/dfb/lib/pkgconfig

    之前安装了GTK开发包，默认情况下，它自动编译了示例程序，这里可以直接运行：

#/usr/local/dfb/bin/gtk-demo

正常的话，就会看见在蓝色（也可能是别的颜色）的背景下弹出GTK窗口。会发现GTK窗口的边框消失了，看不见标题栏，最大化及最小化按钮了。这是因为没有用到到窗口管理器。但是DFB提供了一些简单的消息处理。

Meta + Mouse 可以移动窗口

Meta + C 可以关闭窗口

Meta + X + Mousr Movement   可以改变窗口的层叠顺序

提示：Meta键就是我们常说的Windows键，键盘上那个带Windows图标的就是。

 

 

3． 小结

以上是GTK-DFB环境的搭建和简单测试。因为开源软件的更新和维护非常的频繁，所以我们需要注意到各个版本的更新，有时候需要及时打上补丁。当然最快捷的方式依照前人实际测试通过的环境来进行。

为了进一步熟悉环境，我们可以尝试运行GIMP,Mozilla-dfb等经典应用实例。
