致命错误： ros/ros.h： 没有这样的文件或目录 1 |#include "ros/ros.h"

Question

有很多与此相关的问题，但我找不到任何对我有用的。我创建了一个c++脚本来订阅相机主题。当我尝试运行脚本时，我得到以下错误:

receiver.cpp:1:10: fatal error: ros/ros.h: No such file or directory
1 | #include "ros/ros.h"
|          ^~~~~~~~~~~

，根据我搜索互联网的错误是由于CMake文件。我试了各种方法，都不知道为什么。所以我也添加了我的CMake列表文件下面。请你调查一下。

我用的是ros noetic, ubuntu 20

您需要确保您正在使用CMakeLists.txt文件中的ros库进行构建。确保你有这些行:

add_executable(some_exe src/your_source.cpp)
target_link_libraries(some_exe ${catkin_LIBRARIES})

当然，将some_exe和src/your_source.cpp替换为您的包中的正确名称。
