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

问题描述

有很多与此相关的问题，但我找不到任何对我有用的东西。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，出现以下错误。

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

根据我在互联网上的搜索，错误是由于 CMake 文件造成的。我尝试了各种方法无法弄清楚为什么。所以我还在下面添加了我的 CMake 列表文件。请调查一下。

cmake_minimum_required(VERSION 3.0.2)
project(cv_basics)

## Compile as C++11, supported in ROS Kinetic and newer
add_compile_options(-std=c++11)

我正在使用 ros noetic 和 ubuntu 20

解决方案

您需要确保使用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，在你的包中用它们各自正确的名称替换some_exe和。src/your_source.cpp
