從零開始移植QT4.8.5之三--linux下交叉編譯QT執行庫
阿新 • • 發佈：2019-01-10
這篇文章要實現的目標是在linux下交叉編譯QT在嵌入式裝置OK6410的執行庫，最終在OK6410上執行QT演示程式。
1、觸控式螢幕庫檔案安裝tslib
首先如果嵌入式裝置上有觸控式螢幕，需要先移植tslib，這個不是本次的重點，所以我們就直接搭建編譯的時候需要的tslib庫，因為飛凌官方已經提供編譯好了的庫檔案，所以之需要解壓把庫檔案放到對應的位置就可以了。
解壓到準備好的目錄，這個目錄需要記住，後面在編譯QT的時候會用到，我的路徑是/home/linux/arm/tslib目錄下。
2、交叉編譯qt-everywhere-opensource-src
需要在上一篇文章中的壓縮包qt-everywhere-opensource-src-4.8.5.tar.gz，這裡需要重新解壓，因為如果已經configure過的會生成makefile檔案，qt的configure會檢測資料夾中是否有makefile，即使使用make clean也無法完全刪除配置檔案，在編譯的時候可能會產生各種各樣的路徑、編譯庫不一致的錯誤，所以最好的方法就是每次編譯之前都從新解壓。
tar zxvf xxx.tar.gz
解壓之後跳進解壓後的資料夾
輸入如下命令
echo yes | ./configure -opensource -embedded arm -xplatform qws/linux-arm-g++ -no-webkit -qt-libtiff -qt-libmng -qt-mouse-tslib -qt-mouse-pc -no-mouse-linuxtp -prefix /home/linux/arm/qt-4.8.5-arm -I /home/linux/arm/tslib/include -L /home/linux/arm/tslib/lib這裡說明幾個重要的設定
-prefix /home/linux/arm/qt-4.8.5-arm 這個是編譯好的檔案的目錄，這個目錄很重要，因為在開發板上也要將庫檔案放在這個目錄中，所以需要謹慎選擇。
-I /home/linux/arm/tslib/include 這個是剛剛解壓好的tslib庫的路徑下的include
-L /home/linux/arm/tslib/lib 這個是剛剛解壓好的tslib庫的路徑下的lib
這幾個需要根據自己的需求修改。
然後等著configure完成之後就可以經典的make&&make install
沒有意外的話就會在/home/linux/arm/qt-4.8.5-arm路徑下生成編譯好的庫檔案
3、提取開發板需要的庫檔案

根據自己的需要修改home/linux/arm/qt-4.8.5-arm路徑，如果QT的版本改變可以根據自己需要修改其中對應的版本號，4.8.5和4.8，其他的內容基本不需要改變。
之後把target-qte-4.8.5.tgz檔案拷貝到開發板的根目錄下，然後解壓就可以了，之後就會在開發板的/home/linux/arm/qt-4.8.5-arm目錄下會有QT庫檔案了。
到這個時候就可以在開發板上執行QT程式了，下面我們提供一個QT演示程式的指令碼檔案。

這個指令碼只能在OK6410開發板4.3寸螢幕上執行，具體的內容請讀者自己閱讀，下一篇文章我們會一起自己寫一個QT程式執行起來。那個時候我們來對自己的程式一些環境配置具體的講解。
