 ### 搭建系统基础环境
 
-在搭建各个开发板环境前，需要完成OpenHarmony系统基础环境搭建。系统基础环境主要是指OpenHarmony的编译环境和开发环境，详细介绍请参考官方站点[Ubuntu编译环境准备](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/quick-start/Ubuntu%E7%BC%96%E8%AF%91%E7%8E%AF%E5%A2%83%E5%87%86%E5%A4%87.md)。开发者需要根据环境搭建文档，完成下述软件的安装：Python3.7+、gn、ninja、hb。对于LiteOS-M内核，还需要安装Make构建工具和[ARM GCC编译工具链](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)。
