qtlinux下載

① 在linux下做圖形界面的系統要用到qt 嗎，我下載了qt5.5，這個和linux是獨立的

linux可以用QT 做圖形界面。也有QT的版本。windos的也有，所以你可以直接下一個linux版本的QT 就可以使用了

② qt-opensource-linux-x64-5.6.3.run有沒有對應的32位版本，官網上沒找到，有什麼辦法可以解決

建議用 5.5.1 ，功能差不了太多，要不就得自己在32位系統下從源碼編譯Qt了。

先確認必須在32位系統下使用的必要性。再看看5.6的新功能是否有必須用到的。

③ 如何安裝qt for linux

一、下載

1
首先，前往如圖所示的官網地址下載需要的Qt組件。

2
在下載頁面中，單擊如圖所示的Download下載按鈕。該版本是可供大家免費使用的。

3
接下來，在打開的頁面中，注意不單擊那個顯著的Download Now下載按鈕，這其實是下載一個安裝器到本地電腦，用安裝器下載Qt的速度很慢。
我們單擊下面的 View All Downloads 文字鏈接，打開真實的Qt下載地址直接下載。

4
頁面打開後，就可以單擊鏈接直接下載所需的Qt組件了。
在 windows 下常見的安裝方式需要下載的組件如下：
1）32 位 Windows，使用 MinGW：下載 Qt 5.4.0 for Windows 32-bit (MinGW 4.9.1) 【註：系統上無須已安裝 MinGW】
2）32 位/64位 Windows，使用 VS2013：下載對應版本的 VS2013 Qt 5.4.0 for Windows 32/64-bit 【註：系統上需要已經安裝 VS2013】
3）32 位/64位 Windows，使用 OpenGL：下載對應版本的 Qt 5.4.0 for Windows 32/64-bit VS 2010/2012/2013, OpenGL【註：系統上需要已經安裝 VS2010/2012/2013】

在這兒需要提醒大家注意：
1）要根據自己的電腦系統來選擇組件。比如以上下載鏈接請先認準是在 windows 主機一欄下的鏈接。如果是 Linux 系統，則應到 Linux 主機一欄下去找下載鏈接
2）無需另外下載 Qt Creator 集成開發環境，以上每組組件均已包含

⑤ Linux怎麼下載QT怎麼安裝QT怎麼找不到QT的安裝包主要回答一下怎麼弄到QT安裝包謝謝

QT現在賣給諾基亞了，你要找QT安裝包，當然要去諾基亞的網站上去找咯。
作為開發者，我們需要下載的是QT SDK。
在QT SDK的安裝過程中，用戶可以自主選擇要安裝的組件。 另外，用戶會將會收到插件更新提醒，例如， QT Creator和/或新目標，並不需要額外的升級和多餘的下載。
