- 如果在Linux下使用，请自行下载[GNU GCC工具链][3]。
- 如果在Linux下使用，推荐用发行版的包管理器安装 `arm-none-eabi` 工具链，`rtconfig.py` 默认的 `EXEC_PATH` 即为 `/usr/bin`，装好后无需额外配置。以 Debian/Ubuntu 为例：

```shell
sudo apt install gcc-arm-none-eabi libstdc++-arm-none-eabi-newlib
```

其中 `libstdc++-arm-none-eabi-newlib` 提供链接阶段 `-lsupc++` 所需的库。也可以从 [Arm GNU Toolchain 下载页][3] 获取官方预编译版本，解压后用 `RTT_EXEC_PATH` 环境变量指向其 `bin` 目录。
