Linux C程序编译
准备源码
打开网盘到 5_MY-Demo -> MY-Linux-C-Demo，下载 hello.c 文件，并复制到虚拟机。
编译目标文件
=====> Input:
$CC hello.c -o hello.out
Note: 如果有“未找到命令”的信息，是因为交叉编译工具链的配置没有生效，可以按前面 “交叉编译工具链安装” 中的 “source 工具链配置文件” 操作一次后再执行此步骤

把编译得到的 hello.out 复制到开发板上
在开发板上运行Linux C目标程序
=====> Input:
chmod +x ./hello.out
./hello.out

解压源码包到工作目录
=====> Input:
tar xf MY-Linux-QT5-Demo-AboutUs-svn*.tar.bz2 -C ~/my-work/02_source/
QT程序编译
进入源码目录
=====> Input:
cd ~/my-work/02_source/AboutUs/
生成Makefile文件
=====> Input:
qmake
Note: 如果有“未找到 ‘qamke’ 命令”的信息，是因为交叉编译工具链的配置没有生效，可以按前面 “交叉编译工具链安装” 中的 “source 工具链配置文件” 操作一次后再执行此步骤
编译目标文件
=====> Input:
make
=====> Output:
/home/myzr/my-work/03_toolchain/fsl-imx-x11-glibc-x86_64-meta-toolchain-qt5-cortexa7hf-neon-toolchain-4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/bin/qt5/uic widget.ui -o ui_widget.h

在文件系统增加自己的应用
准备工作
创建编译工作目录
=====> Input:
mkdir ~/my-work/04_image -p
将烧录工具上的文件系统 Profiles/Linux/OS Firmware/image-L4.1.15-rootfs/L4115-*-myimx6a9.tar.bz2 复制到 ~/my-work/04_image
创建存放文件系统的目录
=====> Input:
mkdir L4115-fsl-image-qt5-myimx6a9
【注意】：上面的 L4115-fsl-image-qt5-myimx6a9 改为与文件系统压缩包对应的名称。
L4115-fsl-image-qt5-myimx6a9
L4115-fsl-image-gui-myimx6a9
L4115-core-image-base-myimx6a9
解压文件系统压缩包并进入到解压目录
=====> Input:
tar jxvf L4115-*-myimx6a9.tar.bz2 -C L4115-*-myimx6a9/
cd L4115-*-myimx6a9

重新压缩文件系统
=====> Input:
sudo tar cjvf ../L4115-fsl-image-qt5-myimx6a9.tar.bz2 *
cd ..
【注意】：上面的 L4115-fsl-image-qt5-myimx6a9.tar.bz2 改为文件系统压缩包对应的名称。
L4115-fsl-image-qt5-myimx6a9.tar.bz2
L4115-fsl-image-gui-myimx6a9.tar.bz2
L4115-core-image-base-myimx6a9.tar.bz2
最后将压缩好的包复制到烧录工具相应的目录进行烧写
