ROS Build Error - Wasn't finding the ROS include Directory for lib files.

[Madhava Pandiyan]

Hi,

I had tried to run the demo file for ROS custom handler. While I tried to build it, it gave an error mentioning that it is unable to identify some files from ROS include Directory. But on further check I realized that those files are not missing, but the path to the directory is not being detected. Could someone please help me resolve this issue?

In Chrono, I have enabled following modules:

- Irrlicht

- ROS

- Vehicle

In addition I have also enabled:

- Openmp

I am running it in Ubuntu 20.04. I have installed ROS2 Galactic. (I am getting same error in another system with Ubuntu 22.04 and ROS2 Humble). 

I have attached the error message along with the source files to this post.

Thank you in advance.

Looks like you didn’t request Chrono::ROS as a component in find_package.

Try modifying your CMakeLists.txt to:

find_package(Chrono

             COMPONENTS Irrlicht ROS

             OPTIONAL_COMPONENTS

             CONFIG)

 

(of course, if later on you want to also use Chrono::Vehicle, add that module as well).
