Include path for custom interface files in ROS2

edit

Hey there, did you ever figure out this issue? I'm also seeing this issue.

Hello there,

Have you tried configuring your compilers properties on VSCode (the c_cpp_properties.json file for example) by editing the IncludePath variable and adding the include file of your interfaces package (your_ros2_worspace_dir/install/your_interface_package_dir/include).

This should tell VSCode where your header files are.

Be sure you've installed the ros extension for one. Aside from this, if you open the ros_ws folder (i.e. the one which holds the install, build, and src folders) then it should configure itself automatically.

If it doesn't, open the .vscode/c_cpp_properties.json file and check that it contains the correct includePath (the most important for this being ${workspaceFolder}/** and /opt/ros/foxy/include/**). Mine for example:

{
  "configurations": [
    {
      "browse": {
        "databaseFilename": "",
        "limitSymbolsToIncludedHeaders": true
      },
      "includePath": [
        "${workspaceFolder}/**",
        "/opt/ros/foxy/include/**",
        "/usr/include/**"
      ],
      "name": "ROS"
    }
  ],
  "version": 4
}

Again, for this to work vscode has to open in your ros_ws directory, such that it can walk through the install and src folders. Otherwise you can add them by manually backstepping in the include.

I've inspired my setup a bit by https://www.allisonthackston.com/articles/vscode-docker-ros2.html, she provides a docker for a vscode setup. I've taken some inspiration here regarding figuring out some of the slightly more obscure settings.
