You seem to be missing RoboclawEncoderSteps.h

csvance commented

Did you source your ros workspace setup file before running catkin_make?

ie, source ~/catkin_ws/devel/setup.bash

Rafcin commented

I can't build the project becuase the file is missing when trying to compile it. You are missing the file I referenced above.

csvance commented

RoboclawEncoderSteps.h is a message header file which gets automatically generated by ROS when you run catkin_make.

edit Huh my bad the file generated. It seems what happened was the catkin build didn't complete the job correctly and never actually made it, running catkin build roboclaw worked just fine!

Sorry for the inconvenience!

I ran into the same issue. Fresh workspace, ROS Melodic. master branch. Sourcing didn't (and shouldn't) make a difference.

Running catkin_make a second time does succeed. This looks like the following ROS answers question: compile twice to see custom message

The reason is suddenly started working for @Rafcin is that he just ran it a second time. @csvance you might want to reopen this issue, happy to create a PR to fix
