I.MX6Q SABRE Lite在Ubuntu下编译QT4.8.4

英蓓特 I.MX6Q SabreLite开发板

1. 下载qt4.8.4源码  http://download.qt.io/archive/qt/4.8/4.8.4/qt-everywhere-opensource-src-4.8.4.tar.gz

2.创建目录/home/wps/qt/ , 将下载的源码解压到此目录, /home/wps/qt/qt-everywhere-opensource-src-4.8.4为解压后所在目录

3.创建目录/home/wps/qt/qt-4.8.4_sabrelite ,此为安装目录

4.下载 Building QT for I.MX6 中附件linux-imx6-g++.tar.gz   和 0001-add-i.MX6-EGL-support.patch.zip ,并解压linux-imx6-g++.tar.gz 到/home/wps/qt/qt-everywhere-opensource-src-4.8.4/mkspecs/qws下 ,由于Building QT for I.MX6 中所述的过程基于Freescale的LTIB ,我们使用的是英蓓特Embest 公司提供的i.MX6QSABRELite-development-environment.sh 开发环境.自带交叉编译工具 ,因此需要改变linux-imx6-g++.tar.gz 中的qmake.conf 中的配置信息 .

修改方式如下:

原内容如下:

打补丁:

在目录/home/wps/qt/qt-everywhere-opensource-src-4.8.4 下输入补丁命令

$ patch -p1<0001-add-i.MX6-EGL-support.patch

5. 下一步为QT配置 :

在/home/wps/qt/qt-everywhere-opensource-src-4.8.4下输入命令如下,其中Building QT for I.MX6 中没有加上 -no-pch ,我编译时出错

./configure -qpa -arch arm -xplatform qws/linux-imx6-g++ -no-largefile -no-accessibility -opensource -verbose -system-libpng -system-libjpeg -system-freetype -fast -opengl es2 -egl -confirm-license -qt-zlib -qt-libpng -no-webkit -no-multimedia -make examples -make demos -release -make libs -exceptions -no-qt3support -no-pch -prefix /home/wps/qt/qt-4.8.4_sabrelite

6. 使用 make -j4编译 ,-j4 根据电脑配置调整

完成后  make install ,则/home/wps/qt/qt-4.8.4_sabrelite中为所需内容

7. 根据QT 通常配置, 编译器为/home/wps/timesys/i_MX6QSABRELite/toolchain/bin/armv7l-timesys-linux-gnueabi-g++

QT 的qmake版本为/home/wps/qt/qt-4.8.4_sabrelite/bin/qmake

配置Kits

8. 完成I.MX6 SabreLite 使用i.MX6QSABRELite-development-environment.sh 开发环境下的QT4.8.4编译
