GT2440 加载可执行文件到开发板步骤.docx

本人只是一个初学者，吃了很多苦头，现在将一些经验分享一下，希望可以帮助到后来者。系统与国嵌视频中的系统一样。该“简单计算器”程序可在我的另一份文档中找到。这只是一个例子，其他程序可以依样画葫芦弄出来。rootlocalhost # cd /home/lgl/calculatorrootlocalhost calculator# lscwidget.cpp cwidget.h

./calculator/生成的简单计算器如图左上角所示。生成的计算器可在Linux虚拟系统中运行，但不可加载到GT2440开发板上面，只是一个虚拟程序。若想生成可加载到开发板的程序，则需用另一种编译方法。在GT2440开发板的资料中有hello这个可测试文件，我们就用它来修改就行了，将hello文件夹中的build和hello.pro文件复制到calculator文件夹中，之后rootlocalhost
