error: ‘LivoxEthPacket’ has not been declared

这个错误提示通常表示你的代码中使用了一个未声明的类或结构体 LivoxEthPacket。你需要确保在使用该类之前已经正确地声明和引入了它的头文件。如果你已经包含了相关的头文件,可能是命名空间或作用域的问题,你可以检查一下你的代码中是否有使用该类的命名空间或作用域限定符。另外,也可以检查一下该类的定义是否有错误或缺失。希望能对你有所帮助。

std::experimental has not been declared
The error message "std::experimental has not been declared" means that the compiler cannot find a definition for the experimental header file in the standard library. This header file contains experimental features that are not yet standardized and may not be available on all platforms.
To fix this error, you need to make sure that your compiler supports the experimental header file and that you have included it in your code. You can include the experimental header file using the following code:
```cpp
#include <experimental/some_header_file>
```
Alternatively, you can use the non-experimental version of the header file if it is available in the standard library. For example, if you are using an experimental version of the filesystem header file, you can use the non-experimental version by including the following code:
```cpp
#include <filesystem>
```
Keep in mind that experimental features may change or be removed in future versions of the standard, so it's important to check the documentation for the specific feature you are using and to test your code thoroughly.
error: ‘nv’ has not been declared
如果在使用 `nv::getInferLibVersion()` 函数时出现了 `error: ‘nv’ has not been declared` 的错误,可能是因为你的代码没有正确地包含 TensorRT 的头文件。在 C++ 中,使用 TensorRT 库需要包含相应的头文件,例如 `NvInferRuntimeCommon.h`。
请确保你的代码中包含了正确的 TensorRT 头文件,并使用了正确的命名空间。可以参考以下代码:
```
#include "NvInferRuntimeCommon.h"
#include <iostream>
int main()
{
std::cout << "TensorRT version: " << nv::getInferLibVersion() << std::endl;
return 0;
}
```
如果还是出现了 `error: ‘nv’ has not been declared` 的错误,请检查你的代码中是否缺少必要的头文件或者命名空间声明。
