感谢楼主 真是辛苦了
但我是个初学者 不怎么会安装linux下的软件
找了一下具体的安装方法 和跟我一样的初学者共享一下
On Linux/Unix, you need to make the file executable in order to run it. You can either do this with your desktop's file manager or, at the command line, type:
chmod u+x qt-sdk-linux-x86-opensource-2009.03.bin
You should now be able to execute the file as normal. You can do this from the command line by typing:
./qt-sdk-linux-x86-opensource-2009.03.bin
