Linux怎么下载QT？怎么安装QT？怎么找不到QT的安装包？主要回答一下怎么弄到QT安装包？谢谢

QT现在卖给诺基亚了，你要找QT安装包，当然要去诺基亚的网站上去找咯。

作为开发者，我们需要下载的是QT SDK。

在QT SDK的安装过程中，用户可以自主选择要安装的组件。 另外，用户会将会收到插件更新提醒，例如， QT Creator和/或新目标，并不需要额外的升级和多余的下载。

下载地址：http://qt.nokia.com/downloads-cn

建议用 5.5.1 ，功能差不了太多，要不就得自己在32位系统下从源码编译Qt了。

http://download.qt.io/archive/qt/5.5/5.5.1/

先确认必须在32位系统下使用的必要性。再看看5.6的新功能是否有必须用到的。

Hence, the binary Qt releases for Windows and Mac will not contain prebuilt handlers for those formats, but users can still build them from source.

Deprecated Modules

The following modules are part of Qt 5.6 release, but deprecated and considered for removal in subsequent releases of Qt:

Qt Script

Qt Enginio

Removed Modules

With Qt 5.6 the following modules are no longer part of the release packages, but users can still build them from source:

一、下载

1

首先，前往如图所示的官网地址下载需要的Qt组件。

2

在下载页面中，单击如图所示的Download下载按钮。该版本是可供大家免费使用的。

3

接下来，在打开的页面中，注意不单击那个显著的Download Now下载按钮，这其实是下载一个安装器到本地电脑，用安装器下载Qt的速度很慢。

我们单击下面的 View All Downloads 文字链接，打开真实的Qt下载地址直接下载。

4

页面打开后，就可以单击链接直接下载所需的Qt组件了。

在 windows 下常见的安装方式需要下载的组件如下：

1）32 位 Windows，使用 MinGW：下载 Qt 5.4.0 for Windows 32-bit (MinGW 4.9.1) 【注：系统上无须已安装 MinGW】

2）32 位/64位 Windows，使用 VS2013：下载对应版本的 VS2013 Qt 5.4.0 for Windows 32/64-bit 【注：系统上需要已经安装 VS2013】

3）32 位/64位 Windows，使用 OpenGL：下载对应版本的 Qt 5.4.0 for Windows 32/64-bit VS 2010/2012/2013, OpenGL【注：系统上需要已经安装 VS2010/2012/2013】

在这儿需要提醒大家注意：

1）要根据自己的电脑系统来选择组件。比如以上下载链接请先认准是在 windows 主机一栏下的链接。如果是 Linux 系统，则应到 Linux 主机一栏下去找下载链接

2）无需另外下载 Qt Creator 集成开发环境，以上每组组件均已包含

END

二、安装

组件下载后，双击即可启动安装。

首先是选择安装目录。

然后是选择要安装的项目，一般全部勾选。

选择同意条款。

点击下一步。

到了如下界面时，一切安装前准备工作就已经做好了，点击“安装”按钮静心等待安装完成就可以了。
