安裝需要套件
編譯需要的一些套件            build-essential(dep:gcc, g++, make等)
Debugger                          gdb
GLX development files       libgl1-mesa-dev
# apt-get install build-essential libgl1-mesa-dev gdb

進入下載目錄
# cd /home/clementyan/Downloads/

更改檔案權限，增加可執行的權限
# chmod +x qt-opensource-linux-x64-android-5.4.1.run

執行安裝程式
# ./qt-opensource-linux-x64-android-5.4.1.run

新增qtcreator連結檔，連結到/opt/Qt5.4.1/Tools/QtCreator/bin/qtcreator
# cd /usr/local/bin/
# ln -s /opt/Qt5.4.1/Tools/QtCreator/bin/qtcreator qtcreator
