Ubuntu安装Qt的方法很多，可以用命令安装，可以在新立得里安装，也可以在网站下载软件包！
Ubuntu是很方便的，安装东西一条命令就解决了！
我说说我在网站上下载的.bin格式文件的Qt Creator的安装过程吧！(我初学Qt，仅供参考！)
先在网站下载qt-sdk-linux-x86-opensource-2009.03.1.bin（我这个时候是最新的了），然后把它保存在一个目录下，一定要注意，必须是英文目录！
打开终端 到那个目录下 输入
chmod +x qt-sdk-linux-x86-opensource-2009.03.1.bin ./qt-sdk-linux-x86-opensource-2009.03.1.bin
之后的操作就跟windows里没什么差别了！它会弹出一个安装向导，按提示做就可以了！
安装后来个HelloQt,
应用程序－>编程－>Qt creator
#include <QApplication>
#include <QMainWindow>
#include <QLabel>
int main(int argc, char *argv[])
{
QApplication app(argc,argv);
QMainWindow *window = new QMainWindow;
window->resize(550,350); //窗口大小
window->setWindowTitle("Hello Qt");
QLabel *label = new QLabel("<h2>Hello World!</h2>");
window->setCentralWidget(label);
window->show();
return app.exec();
}
这样第一个Qt程序就出来了！
