included header xxx is not used directly

这个警告通常表示你在代码中包含了某个头文件,但是在代码中没有直接使用该头文件中定义的任何函数、变量或类型。这可能是一个无意的错误,也可能是你的代码中存在未使用的代码。为了消除这个警告,你可以考虑删除未使用的代码,或者在使用头文件中定义的内容时添加必要的代码。另外,你也可以通过添加 `-Wno-unused-header` 编译选项来忽略该警告。

Information:File is not included in any tsconfig.json
这是一个编程类的问题,可能是因为你的文件没有被包含在任何 tsconfig.json 文件中。你需要将文件添加到正确的 tsconfig.json 文件中,或者创建一个新的 tsconfig.json 文件并将其包含在其中。如果你需要更多的帮助,可以查看 TypeScript 的文档或者在 Stack Overflow 上寻求帮助。
ROSLIB is not defined
ROSLIB is a JavaScript library that is commonly used in Robot Operating System (ROS) applications. It provides the necessary tools and functionality to communicate with ROS from a web browser or JavaScript-based client.
If you encounter an error saying "ROSLIB is not defined," it means that the ROSLIB library has not been properly included in your code or it is not accessible. To resolve this issue, make sure you have included the ROSLIB library in your HTML file or JavaScript code.
You can include the ROSLIB library by adding the following script tag in your HTML file:
```html
<script src="https://cdn.robotwebtools.org/EventEmitter2/current/eventemitter2.js"></script>
<script src="https://cdn.robotwebtools.org/roslibjs/current/roslib.min.js"></script>
```
Alternatively, you can download the ROSLIB library and include it locally in your project.
Once the ROSLIB library is properly included, you should be able to use its functionality in your code without encountering the "ROSLIB is not defined" error.
