1、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 main.cpprootlocalhost calculator# qmake -projectrootlocalhost calculator# qmakerootlocalhost calculator# makeg+

7、p Makefile moc_cwidget.o/上面生成的可执行文件“calculator”的名字是跟文件夹的名字相同的rootlocalhost calculator# ./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 lgl# cd

8、calculatorrootlocalhost calculator# lsbuild cwidget.cpp cwidget.h hello.desktop hello.pro main.cpp/如果build的颜色为黑色，则须执行rootlocalhost calculator#chmod +x build/将build变为可执行文件，然后rootlocalhost calculator# vi hello.pro/打开hello.pro之后可看到如图界面，将其修改为：DESTDIR=$(pwd)表示在当前目录下生成可执行文件，TARGET = calculator表示生成的文件名字为“c
