请注意,在 RT-Thread 中使用 C++ 11需要修改工具链中的部分文件。请在修改之前备份好工具链。
1. 使能 c++11

2. 下载 GCC 工具链
```shell
gcc version 10.2.1 20201103 (release) (GNU Arm Embedded Toolchain 10-2020-q4-major)
```
3. 删除下面的文件
```shell
rm -f toolchain/arm-none-eabi/include/c++/10.2.1/thread
rm -f toolchain/arm-none-eabi/include/c++/10.2.1/mutex
rm -f toolchain/arm-none-eabi/include/c++/10.2.1/condition_variable
rm -f toolchain/arm-none-eabi/include/c++/10.2.1/future
rm -f toolchain/arm-none-eabi/include/pthread.h
```
4. 请清除下面文件的内容,保留文件避免编译失败
```shell
toolchain/arm-none-eabi/include/sys/_pthreadtypes.h
```
5. 更新 `rtconfig.py` 文件,添加 c++ 编译参数:
```shell
CXXFLAGS = CFLAGS + ' -std=c++11 -fabi-version=0 -MMD -MP -MF'
```
