如有錯誤，歡迎批評指正！！！

一、本教程基於周立功EasyARM-i.MX287開發套件

詳詢周立功網站，www.zlgmcu.com

二、系統恢復及相關設定

根據周立功產品使用說明恢復系統，設定系統IP地址為192.168.0.160，掛載到192.168.0.190主機/home/wps/nfs目錄下。

#---------------------------------------
#/etc/rc.d/rcS 開機啟動
ifconfig eth0 192.168.0.160 netmask 255.255.255.0
route add default gw 192.168.0.253
mount -t nfs 192.168.0.190:/home/wps/nfs /mnt -o nolock
 

三、環境搭建

本文使用周立功提供的交叉編譯工具鏈，使用Qt進行開發。

在PC端安裝交叉編譯工具鏈並配置交叉編譯工具鏈路徑：

$gedit .bashrc

#EasyARM-287
PATH=$PATH:/home/wps/programs/toolchains/EasyARM-iMX287/arm-fsl-linux-gnueabi/bin

$source .bashrc

作者使用的開發板上內建周立功公司提供的Qt4.8.4庫，由於作者多數工作在Qt5.4.2下開發，故打算移植QT5.4.2到開發板上。

一開始，開發板上帶有tslib庫，該庫可以滿足Qt4.8.4的圖形介面下的觸控式螢幕控制，作者想偷懶使用，沒想到出現一些問題。

故重新編譯tslib1.4，並編譯QT5.4.2。

編譯Tslib

可參見http://blog.csdn.net/romeolikejuliet/article/details/53234146，

編譯tslib-1.4出現錯誤，參見http://qkxue.net/info/78682/tslib-open-missing-mode-1-4

編譯tslib-1.4，進入原始碼目錄，建立configTslib14.sh，程式碼如下，並執行，安裝目錄/usr/local/tslib-1.4_imx287

 make clean && make distclean    
 echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache    
 CC=/home/wps/programs/toolchains/EasyARM-iMX287/arm-fsl-linux-gnueabi/bin/arm-fsl-linux-gnueabi-gcc ./configure --host=arm-linux --prefix=/usr/local/tslib-1.4_imx287 --cache-file=arm-linux.cache    
sudo make && sudo make install 
 

注意該編譯器下會出現錯誤：

gcc 新版本編譯器對語法檢查嚴格，在原始檔 ./tests/ts_calibrate.c 中

// 原始檔
// if ((calfile = getenv("TSLIB_CALIBFILE")) != NULL) {
//     cal_fd = open (calfile, O_CREAT | O_RDWR);
// } else {
//   cal_fd = open ("/etc/pointercal", O_CREAT | O_RDWR);
// }
// 需要更改成如下形式
if ((calfile = getenv("TSLIB_CALIBFILE")) != NULL) {
    cal_fd = open (calfile, O_CREAT | O_RDWR, 0777);
} else {
    cal_fd = open ("/etc/pointercal", O_CREAT | O_RDWR, 0777);
}

首先在qt-everywhere-opensource-src-5.4.2/qtbase/mkspecs/目錄中，複製linux-arm-gnueabi-g++，重新命名為linux-arm-fsl-gnueabi-g++，修改qmake.conf檔案，使用周立功公司提供的arm-fsl-linux-gnueabi編譯器

NOTE: Qt is using double for qreal on this system. This is binary incompatible against Qt 5.1.
Configure with '-qreal float' to create a build that is binary compatible with 5.1.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /home/wps/programs/qt/Qt5.4.2/qt-5.4.2_imx287

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

因為開發板容量限制，使用者可以選擇性複製相關檔案，本文複製資料進/usr/local/qt-5.4.2_imx287中，首先修改/etc/rc.d/init.d/start_userapp，關閉啟動介面，
