warning: #pragma once in main file的回答 #pragma once的作用: #pragma once是一个预处理指令,用于防止头文件被多次包含(即多重包含)。当编译器遇到#pragma once时,它会确保当前文件在当前编译单元中只被包含一次。这有助于避免由重复包含同一头文件而导致的编译错误和性能问题。

We do some manual header insertion into the ROS2 bindings .cc file to fix some import errors. This commit skips copying of the #pragma once attribute at the beginning to avoid a C++ warning.

To help you identify where the issue is, diagnostic messages typically contain both the filename and line number where the compiler found the issue, and some text about what was expected vs what was found. The actual issue may be on that line, or on a preceding line. Once you’ve addres...
