Building a basic buildreoot file system

1、 Atomic tutorial buildroot edition ：buildroot-2019.02.6.tar.bz2​​​​​​​

2、 decompression ,make menuconfig ( no need source)

3、 Change to the options in brackets

1）Target options

2）Toolchain（ Configure the cross compiler , I don't know why linaro-gcc, instead of nxp Provided x11）

3、 System configuration

doubt ：systemd  systemv busybox ? What is this? ？

Choose different system initialization methods ？yocto and systemd What are these relations ？  

 4、Filesystem images

5、Kernel（ No election , Don't compile ）

 6、Boot-loaders（ No election , Don't compile ）

 7、Target packages（ Third party software , Atoms are not recommended for beginners , I don't understand , Just listen to him first ）

8、 compile

sudo make

Report errors ：

  hum , This little bit of tabloid error , The answers told me , It can't be solved ？

Continue compiling ：

An error again ：

solve ：

sudo vi /etc/profile

Additional ：FORCE_UNSAFE_CONFIGURE=1

Restart the terminal

No dice

Direct input ：$ export FORCE_UNSAFE_CONFIGURE=1

It's no use

Consulting brother ：

$ sudo make FORCE_UNSAFE_CONFIGURE=1

It works

  Long wait ..., I'm going to bed , I hope you don't make a mistake when you wake up

After midnight, the Internet is very fast , But it's wrong

More than a - ？

go back to menuconfig, hold Toolchain Configure the cross compiler there ,linux-gnueabihf- - Get rid of

Continue compiling ： Listen to the atoms （ structure buildroot-2019.02.6.tar.bz2 Required source code ：cmake-3.8.2.tar.gz and zlib-1.2.11.tar.xz） Download and copy to buildroot-2019.02.6/dl

40 minute , Compiled

9、 stay buildroot-2019.02.6/output/images Generate root file system under

Can you use , Have time to verify , zero 44 了 , I have to work tomorrow —— Don't compromise with yourself , Have to compromise with life .
