这篇博文并不介绍如何交叉编译qt-everywhere来利用宿主机进行qt程序的交叉编译
因为在使用qt-everywhere源码中的configure脚本进行编译配置时，需要提供嵌入式设备的sysroot来判断部分组件是否被支持并勾选编译，而我配置的ubuntu根文件系统在利用configure脚本进行编译时，由于依赖的缺失，无法编译eglfs X11及xcb相关项目，导致最终编译出的qmake交叉编译出的程序无法在嵌入式设备上良好的运行eglfs
（折腾好几天了，决定先放一放）
这里另辟蹊径是在宿主机上挂载嵌入式设备的rootfs（例如我之前配置好的ubuntu根文件系统https://blog.csdn.net/sements/article/details/88086468），在其中安装qmake，及编译器。在宿主机上
来利用宿主机的性能另辟蹊径的编译能够在嵌入式设备上运行的qt程序
egl - EGL，它是图形渲染API（如OpenGL ES）与本地平台窗口系统的一层接口，保证了OpenGL ES的平台独立性
eglfs - egl full screen
xcb - X protocol C-language Binding (XCB) c语言x协议绑定
以下操作为挂载根文件系统后在其中的操作
1 - 根文件系统环境准备
可参考 移植ubuntu 18.04.2 到arm平台（i.MX6UL）- ubuntu根文件系统的修改与配置（从零开始的掉头发生活 )
安装 qt5-default , gcc,g++ 。这里gcc和g++是我利用apt安装pkg-config时自动依赖安装的
通过 apt list --installed |grep gcc，我得到了下列输出。推断可能通过命令安装gcc及gcc-8-base包，然后apt会附带的安装好其余依赖（未尝试，欢迎解惑）
sements@ubuntu:~/developArea/qeyes$ apt list --installed |grep gcc WARNING: apt does not have a stable CLI interface.

sudo apt install qt5-default gcc gcc-8-base g++ g++-7由于是armhf的嵌入式根文件系统，这里gcc实际上链接的是arm-linux-gnueabihf-gcc
通过tab键自动联想看一下是否相关的组件已经安装

例如，我们将待编译的qt代码项目（qeyes）放置在了 /home/sements/developArea目录下
为防止编译器将程序生成为共享库文件（application/x-sharedlib），我们在qt代码项目的pro文件内加入下面语句
QMAKE_LFLAGS += -no-pie
然后执行qmake，生成Makefile。查看一下Makefile中的设置

注意查看下CC，CXX以及LFLAGS中是否加入了-no-pie来避免编译成共享库文件
执行make，不用多线程的话稍微有点慢
make -j8就可以看到生成了可在嵌入式设备上运行的可执行文件，但是注意，这样编译出来的是基于共享库的，非静态库连接的程序，所以需要嵌入式设备上搭建qt环境（简单粗暴直接在嵌入式设备上apt install qt5-default）
