1、交叉编译工具链下载位置：
https://github.com/raspberrypi/
不能下载，评论告诉我，发给你们
2、从共享文件夹拷贝到工作目录
cp /mnt/hgfs/share/tools-master.zip /home/CLC
3、解压
unzip tools-master.zip
5、检查版本gcc -v ，主要检查arm-linux-gnueabihf-gcc交叉编译工具版本4.8.3
CLC@Embed_Learn:~/lessonPi/tools-master/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin$ cd
CLC@Embed_Learn:~$ gcc -v
Using built-in specs.

6、创建一个.c文件，分别用gcc和arm-linux-gnueabihf-gcc 编译，并且查看文件的可执行类型（file + 文件名）
CLC@Embed_Learn:~$ vi test7.c
CLC@Embed_Learn:~$ gcc test7.c -o one
CLC@Embed_Learn:~$ arm-linux-gnueabihf-gcc test7.c -o armOne
CLC@Embed_Learn:~$ file one
one: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x180c6c1ee033fd666d2235a65887095416530e8d, not stripped
// x86-64,指的是32、64位
CLC@Embed_Learn:~$ file armOne
armOne: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0x2e52782540abf590a8129961866c5dd81b4becb4, not stripped
// 指的是executable, ARM
7、显然 arnOne是不可再Ubuntu上运行的，只能在ARM上运行（如下载到树莓派开发板上运行）
CLC@Embed_Learn:~$ ./one
Hello
CLC@Embed_Learn:~$ ./armOne
bash: ./armOne: cannot execute binary file
8、把UBuntu上的armOne文件拷贝到树莓派上
指令 文件名 开发板用户名@开发板地址：开发板的绝对路径
CLC@Embed_Learn:~$ scp armOne pi@192.168.111.1:/home/pi
The authenticity of host '192.168.124.14 (192.168.111.11)' can't be established.
ECDSA key fingerprint is f0:e9:43:8c:41:c1:db:87:6f:cc:79:56:86:00:6b:e3.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.111.1' (ECDSA) to the list of known hosts.
pi@192.168.124.14's password:

CLC@Embed_Learn:~$ scp one pi@192.168.124.14:/home/pi

9、我们可以看到树莓派上已经存在one和armOne 文件
pi@raspberrypi:~ $ ls
armOne one Pictures Public Templates Videos
11、在树莓派上运行看看效果
pi@raspberrypi:~ $ ./one
-bash: ./one: cannot execute binary file: Exec format error
pi@raspberrypi:~ $ ./armOne
Hello
12、OK！！！
