一、目的/概述

对比高集成度的IDE(MDK、IAR等)，Linux开发需要自己写Makefile等多种脚本。eclipse、Visual Studio等需要了解预处理、编译、汇编、链接的过程，但无需自己完整编写。并且各大芯片厂家都有基于eclipse的IDE（cube ide、e2studio、ccs、MCUX、Simplicity），支持vs code的插件，国产rtt也有基于eclipse的RT-Thread Studio。
所以，我们介绍eclipse+Arm GNU Toolchain+newlib相关概念，使之有个宏观的概念认识。

三、逻辑和包含关系

• Arm GNU Toolchain命名规则：
  arm-none-eabi-gcc
  arm：架构是arm
  none：不是特定的供应商提供的
  eabi：eabi：嵌入式应用二进制接口（Embedded Application Binary Interface）
  因为名称里没有“linux”类似的字样，说明不支持操作系统。

四、Arm GNU Toolchain最常用的命令

• arm-none-eabi-gcc

• arm-none-eabi-gdb

• arm-none-eabi-size

• arm-none-eabi-objdump
