问题：在编译Android 系统kernel源码的时候出现错误

I am trying to build android project

Getting below error even after setting correct path for toolchains

/bin/sh: lzop: not found
  AS      arch/arm/boot/compressed/piggy.lzo.o
arch/arm/boot/compressed/piggy.lzo.S: Assembler messages:

解决办法
Here is a solution if you’re using Ubuntu:

$ sudo apt-get install lzop

or look for the lzop package of you OS.
