Ubuntu12.04 install Qt (installed in software source)

In another blog, I talked about downloading software from the official website to install Qt. However, in command line mode, the first example in a book cannot be implemented, it seems that the environment is not configured properly. It is said that the software installed in the software source does not need to configure the environment, it is estimated that the system is automatically configured during the installation, so this time I install Qt in the software source, the following describes how to install Qt in the software source.

wahaha@ubuntu-K55VD:~$ sudo apt-get install qtcreator[sudo] password for wahaha:

The information displayed during the installation process is as follows (from the content, it seems that there are some details in the case of 125-132 rows, but this does not affect us currently ).

Hello. cpp source code and running effect (I wrote a hello under the/home/wahaha/Zhuo_Mian/QT code. cpp file. At that time, I put both the code in the book in it, and the result compilation was wrong. So I put only one file under a folder, except for the case where the file is split, A project has multiple files. In addition, my QT code folder is a link Folder whose target file is not a Chinese name ).
