查看“MYZR-A40I-EK204 Linux-3.10.65 编译参考手册”的源代码

源码包的下载需到我们提供的网盘上来进行下载 。下载到电脑后，

需要通过Samba或其他方法将其复制到虚拟机上来。

		我们可以创建一个A40I专属的目录来存放相关的源码，编译工具和以后用到的一些东

西。如我的目录为：**/home/liangyh/my-work/A40I**，在此目录下我又创建了4个子目录：

<pre>
=====> Input:
liangyh@FS12:~/my-work/A40I$ ls
01_image 02_sources 03_toolchain 04_app
</pre>

	01目录可以用来放置我们编译好的镜像（以后用到会说明）

	02目录则是用来放置源码

	03目录则是放置交叉编译工具配置脚本

	04目录我们可以用来放置自己的应用（用户自己分配）

	使用Samba或其他方法将源码包复制到虚拟机中的~/my-work/A40I/02_sources目录

下后将源码包解压到当前目录下：

<pre>
=====> Input:
~/my-work/A40I/02_sources$ cat repo_A40I.tar.bz2a* | tar xjv
</pre>

创建交叉编译工具配置脚本

<pre>
=====> 输入指令：
cat << EOF > ~/my-work/A40I/03_toolchain/arm-openwrt-linux-muslgnueabi.sh
#!/bin/sh
export PATH=${HOME}/my-work/A40I/02_sources/repo_A40I/prebuilt/gcc/linux-x86/arm/toolchain-sunxi-musl/toolchain/bin/:${PATH}
export ARCH=arm
export CROSS_COMPILE=${HOME}/my-work/A40I/02_sources/repo_A40I/prebuilt/gcc/linux-x86/arm/toolchain-sunxi-musl/toolchain/bin/arm-openwrt-linux-muslgnueabi-
export CC=${HOME}/my-work/A40I/02_sources/repo_A40I/prebuilt/gcc/linux-x86/arm/toolchain-sunxi-musl/toolchain/bin/arm-openwrt-linux-muslgnueabi-gcc
EOF

</pre>

获取可执行权限

<pre>
chmod +x ~/my-work/A40I/03_toolchain/arm-openwrt-linux-muslgnueabi.sh
</pre>

......

#### make completed successfully (23:30 (mm:ss)) ####
</pre>

   5.打包固件

<pre>
=====> Input:
$ pack

=====> Output:
No kernel param, parse it from r40
copying tools file
copying configs file

......

/home/liangyh/my-work/A40I/02_sources/repo_A40I/out/r40-m2ultra/tina_r40-m2ultra_uart0.img

pack finish
</pre>

生成固件地址：

<pre>
repo_A40I/out/r40-m2ultra/tina_r40-m2ultra_uart0.img
</pre>

## **应用编程示例**

使用Samba或其他方法将源码包复制到虚拟机中的~/my-work/A40I/04_app目录下。

 **1. 配置交叉编译工具**

<pre>
=====> Input:
$ source ~/my-work/A40I/03_toolchain/arm-openwrt-linux-muslgnueabi.sh 
</pre>

 **2. 检验交叉编译工具配置**

<pre>
=====> Input:
$CC -v

=====> Output:

 **3. 开始编译**

<pre>
=====> Input:
${CC} hello_world.c -o hello_world
</pre>

 **4. 执行**

将编译出的二进制文件hello_world移动到开发板（移动方法参考前面体验篇的文件传输）。

给予可执行权限并执行文件

<pre>
=====> Input:
# chmod +x hello_world
# ./hello_world

=====> Output:
hello world!!!
</pre>

成功运行后成功输出 **hello world** 的信息。



## QT应用编译

将自己的QT应用添加到目录：repo_A40I/package/qt/qt-mydemo/src

<pre>
vi repo_A40I/package/qt/qt-mydemo/Makefile
</pre>

1. 修改 $(1).pro 改为 自己QT应用中 pro文件的名称，如 qt-mydemo.pro

![image-20210610094803854](C:\Users\Administrator\AppData\Roaming\Typora\typora-user-images\image-20210610094803854.png)

2. 修改 qt-mydemo 改为 自己QT应用 生成文件的名称

![image-20210610095153901](C:\Users\Administrator\AppData\Roaming\Typora\typora-user-images\image-20210610095153901.png)

3. 再次编译源码，可以在编译出来的文件系统 (repo_A40I/out/r40-m2ultra/staging_dir/target/rootfs/usr/bin) 中找到生成的QT应用：

![image-20210610095623070](C:\Users\Administrator\AppData\Roaming\Typora\typora-user-images\image-20210610095623070.png)
