目前, 嵌入式Linux操作系统快速发展, 并在手持设备、移动设备中得到广泛应用。因此, 拥有一个实用友好的图形用户界面就显得尤为重要。文章通过交叉编译源码库和应用程序的方式详细说明了Qt/Embedded在嵌入式ARM9上的移值流程, 解决了应用程序跨平台无法运行的问题, 并结合实例对应用的程序开发流程进行了阐述。

At present, the Embedded Linux operating system is rapidly developed and has wide application in handheld devices and mobile equipment.Therefore, possessing a practical friendly graphical user interface is particularly important.This article illustrates the transplantation of Qt/Embedded to Embedded ARM9 in detailed through the mode of crossing compile source repository and application, solves the problem of the cross-platform application not running, and expounds application combined with the development process.
