1. 起源

目标平台为arm架构，无x64或windows安装包

http://download.qt-project.org/archive/qt/5.9/5.9.8/

交叉编译Qt5.9.8_g++

2. 下载qt-everywhere

http://download.qt-project.org/archive/qt/5.9/5.9.8/single/

交叉编译Qt5.9.8_linux_02

tar.xz，这是两层压缩，外面是xz压缩，里层是tar压缩，所以分两步实现解压。

# xz -d qt-everywhere-opensource-src-5.9.8.tar.xz
# tar -xvf qt-everywhere-opensource-src-5.9.8.tar.xz

也可以直接解压
# tar -xvJf qt-everywhere-opensource-src-5.9.8.tar.xz

解压完成

3.2 问题：make:g++:命令未找到

sudo apt-get install g++

3.3 configure编译配置

报错1

Qt5.5.1 configure编译选项,在这里不再介绍。

配置生成make文件时不报错，就可以make了。
