ros/ros.h: No such file or directory after trying tutorial

I've gone through the c++ talker listener tutorials, copy and pasted the code and CMake files into the pkg directory and both nodes worked just fine.

I've now tried to test how well I understand the concept and have make my own package called delete_me. I have one executable called tester.cpp but catkin_make will error with ros/ros.h: No such file or directory. the following is my code and make files


#include "ros/ros.h"
#include "std_msgs/String.h"

#include <sstream>

int main(int argc, char **argv)
    ros::init(argc, argv, "tester");

    ros::NodeHandle n;


    return 0;


cmake_minimum_required(VERSION 3.0.2)

find_package(catkin REQUIRED COMPONENTS


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

I would expect to see the onetime ros log of "Hello" then the node would end. My guess is the CMakeLists.txt file is missing something. Any advice on understanding what I'm missing would be very much appreciated.

Also if it helps I'm using Windows 10 - WSL Ubuntu 20.04 ROS-noetic

You're missing the command that tells CMake where to look for C++ header files when compiling tester.cpp: either target_include_directories or include_directories. See section 7.3 in the catkin docs. It recommends using include_directories, but target_include_directories is the modern preferred style. CMake reference here.

That did it. adding include_directories(include ${catkin_INCLUDE_DIRS}) worked. Thanks for the help
