工作前,必须设置全局参数

1. 位置

./scripts/setup_project_env.source

2. 使用方法

source ./scripts/setup_project_env.source

• 必须source调用
• 可以重复source

3. 包含内容

• 相关变量：工程根目录、源码目录、编译临时目录、发布文件夹目录
• 工具链：封装成函数供调用
• source_toohchain_53_23
• source_toohchain_45_23
• source_toohchain_35_21
• source_toohchain_default

End. Code示意
