树莓派也能跑QT

QT简介 Qt是跨平台的开发库,主要是开发图形用户界面(Graphical User Interface,GUI)应用程序,当然也可以开发非图形的命令行(Command User Interface,CUI)应用程序。 Qt支持众多的操作系统平台,如通用操作系统 Windows、Linux、Unix,智能手机系统 Android、iOS、WinPhone, 嵌入式系统 QNX、VxWorks 等等,应用广泛。当然 Qt 库本身包含的功能模块也日益丰富, 一直有新模块和第三方模块扩充。除了与操作系统底层结合特别紧密的,如驱动开发, 需要利用操作系统本身的函数库实现之外,其他大部分的应用程序开发都可以用 Qt 实现的。 Qt 是纯 C++ 开发的,所以学好 C++ 比较有必要。Qt 还存在 Python、Ruby、Perl 等脚本语言的绑定, 也就是说可以使用脚本语言开发基于 Qt 的程序。 在树莓派上QT安装 打开命令终端运行如下命令 1)sudo apt-get install qt4-dev-tools 2)sudo apt-get install qtcreator
