# 如何编译C++文件
- 目前C++仅支持在`RT-Thread`模式下使用,`RT-Smart`模式暂不支持。环境配置请参考[aarch64_README](../aarch64/README.md)[aarch32_README](../aarch32/README.md)
## Ubuntu环境
- aarch64模式编译链选择`gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf`
- aarch32模式编译链选择`gcc-arm-10.3-2021.07-x86_64-arm-none-eabi`
## RT-Thread Env环境
- aarch64模式编译链选择`gcc-arm-11.2-2022.02-mingw-w64-i686-aarch64-none-elf`
- aarch32模式编译链选择Env环境自带`mingw`编译链
## 编译步骤
- 在`SConscript`文件中添加需要编译的.cpp文件以`aarch64/applications/SConscript`文件为例,其他文件夹请按照需求自行修改

- 输入下列命令,进入 menuconfig 进一步配置
```shell
scons --menuconfig
```
- 勾选`Enable C++ features`,可进入菜单勾选`Enable C++11 standard multi-threading feature support`
![Enable_cpp_features](../figures/Enable_cpp_features.png)
![Enable_Cpp11](../figures/Enable_Cpp11.png)
- 使用`scons -j8`指令进行编译C++文件被正常编译
