qtlinux下载

① 在linux下做图形界面的系统要用到qt 吗，我下载了qt5.5，这个和linux是独立的

linux可以用QT 做图形界面。也有QT的版本。windos的也有，所以你可以直接下一个linux版本的QT 就可以使用了

② qt-opensource-linux-x64-5.6.3.run有没有对应的32位版本，官网上没找到，有什么办法可以解决

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。

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。

③ 如何安装qt for linux

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，注意不单击那个显着的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。

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

⑤ 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。
