..\..\..\source\lock\lock.h(28): error: #20: identifier "hal_gpio_info" is undefined

这个错误提示说明编译器无法找到 `hal_gpio_info` 的定义。可能原因是:
1. 你没有在使用 `hal_gpio_info` 的头文件中引入定义 `hal_gpio_info` 的头文件。
2. 在定义 `hal_gpio_info` 的头文件中有条件编译,导致在使用 `hal_gpio_info` 的头文件中无法访问到。
3. 定义 `hal_gpio_info` 的头文件中,`hal_gpio_info` 的定义代码被注释掉或者不完整,导致无法正确编译。请检查你的代码是否存在这种情况。
解决方法是:
1. 在使用 `hal_gpio_info` 的头文件中引入定义 `hal_gpio_info` 的头文件。
2. 检查定义 `hal_gpio_info` 的头文件中是否有条件编译,以及条件编译的条件是否满足。
3. 检查定义 `hal_gpio_info` 的头文件中是否有注释或不完整的代码。

error in include chain (cmb_def.h): expected identifier or
This error usually occurs when the compiler encounters an unexpected token or character in the include chain. In this case, it seems like the issue is with the `cmb_def.h` header file.
One possible cause of this error is a missing semicolon or other syntax error in a file that is included before `cmb_def.h`. Check the code in the files that are included before `cmb_def.h` to see if there are any errors.
Another possible cause is a circular dependency in the include chain. For example, if `cmb_def.h` includes a file that also includes `cmb_def.h`, this can cause an error. Check the include chain to make sure there are no circular dependencies.
It's also possible that the `cmb_def.h` file itself has an error. Check the contents of `cmb_def.h` to see if there are any syntax errors or other issues.
Overall, this error message can be caused by a number of different issues, so it's important to carefully inspect your code and the include chain to identify the root cause.
