Include information about submodules in ReadMe build steps.
Closed this issue · 1 comments
What?
The ReadMe's Getting Started section jumps directly into using rosdep to install dependencies.
When following along, these errors occurred during the rosdep install --from-paths src --ignore-src --default-yes step.
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
open_mower: Cannot locate rosdep definition for [ftc_local_planner]
mower_comms: Cannot locate rosdep definition for [vesc_driver]
mower_msgs: Cannot locate rosdep definition for [vesc_msgs]
mower_logic: Cannot locate rosdep definition for [slic3r_coverage_planner]Why?
The errors were caused by not having the sources for the listed packages.
How to fix?
To fix the issue, I had to update the submodules. They were not included with the default clone settings (git@github.com:ClemensElflein/open_mower_ros.git)
Fix
To update the submodules
git submodule update --init --recursive
This command will update and initialize (--init) the repository's sub modules, as well as any of the submodule's submodules (--recursive).
After successfully cloning the submodules, rosdep install --from-paths src --ignore-src --default-yes works as intended.
Silly buttons!
