The QtCreator we installed in the classroom is a Windows version, and it is obviously slow during compilation, so I found a Linux version of QtCreator, install Ubuntu 9.04 on the operating system. After the installation, the compilation was attempted, which is much faster than in windows.

We can download the latest version to the http://www.qtsoftware.com/downloads-cn. Qt-sdk-linux-x86-opensource-2009.02.bin

After the download, run the following command on the terminal:

1. Add execution permission to the Installation File

Chmod u + x qt-sdk-linux-x86-opensource-2009.02.bin

2. Execute the installation command

/Qt-sdk-linux-x86-opensource-2009.02.bin
