说明：  linux qt的移植书籍资料，Qt 是一个跨平台的C++图形用户界面应用程序框架。它提供给开发者建立图形用户界面所需的功能，广泛用于开发GUI程序，也可用于开发非GUI程序。Qt是完全面向对象的，很容易扩展，并且允许真正地组件编程。(QT is a cross platform C + + GUI application framework. It provides the functions that developers need to establish graphical user interface. It is widely used to develop GUI programs and non GUI programs. QT is fully object-oriented, easy to extend, and allows true component programming.)

如果您刚接触嵌入式开发，那么大量可用的引导装载程序（bootloader）、规模缩小的分发版（distribution）、文件系统和 GUI 看起来可能太多了。但是这些丰富的选项实际上是一种恩赐，允许您调整开发或用户环境以完全符合您的需要。对 Linux 嵌入式开发的概述将帮助您理解所有这些选项。(Embedded fourth year of development, so much available bootloader (Bootloader). smaller scale version of the distribution (distribution), file system and GUI may seem too much. But these rich options is a gift, allows you to adjust the development or user environment to meet your needs. Embedded Linux for the development of the outline will help you understand all these options.)
