Compile and generate busybox file system

1、 decompression busybox-1.29.0.tar.bz2

2、 my linaro Cross compiler path ：/opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/

3、 Modify the top level Makefile

 164 CROSS_COMPILE ?= /opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

 190 ARCH ?= arm

4、( If you support Chinese characters, don't read them first )

5、make defconfig

6、make menuconfig

Report errors ：

<command-line>: fatal error: curses.h: No such file or directory

solve ：

sudo apt-get install libncurses5-dev 

7、（ The graphical interface can be configured by itself , Don't understand, ）

8、make

9、make install CONFIG_PREFIX=/home/ckl/my_board/nfs/rootfs

10、 Copy library files from the cross compiler （ In fact, you can BSP Chinese compiler , At least yocto Sure ）

/lib library

$ cd /opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/libc/lib

$ cp  *so* -d ~/my_board/nfs/rootfs/lib/

$ cp  *.a -d ~/my_board/nfs/rootfs/lib/

But the tutorial says ：ld-linux-armhf.so.3 This library cannot be a soft link

$ rm ~/my_board/nfs/rootfs/lib/ld-linux-armhf.so.3

$ cp /opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/libc/lib/ld-linux-armhf.so.3  ~/my_board/nfs/rootfs/lib

/usr/lib library

Again cd Go to the appropriate directory

cp *so* *.a -d ~/my_board/nfs/rootfs/usr/lib

I'll give you a warning , I don't know why ：（ I don't care ）

 11、 Create other folders （ Is it necessary , Unclear ,/root, Must be ？）

（ Then compress 、 Replace the file system in the burning package ; Or mount it for use ）
