Solve Dependency on irobot_create_msgs? #7

Closed slowrunner closed 3 years ago

slowrunner commented 3 years ago

The README explains there is a dependency, but I don't know where to put irobot_create_msgs and how to build it?

Posted detailed question at https://robotics.stackexchange.com/questions/22807/getting-a-head-start-with-irobot-create3-ros2

slowrunner commented 3 years ago

Is this the correct solution?

mkdir -p create3_examples_ws/src
cd create3_examples_ws/src
git clone https://github.com/iRobotEducation/create3_examples.git
git clone https://github.com/iRobotEducation/irobot_create_msgs.git   <--- seems to allow the build to proceed.
cd ..
colcon build
source install/local_setup.sh

The irobot_create_msgs dependency is a standard ROS 2 package, so there are no requirements on where to place it and how to build it (as long as the packages that depend on it, e.g. the create 3 examples, can find it).

The two most common options are:

clone the package in the same workspace as the examples and build everything together.
clone the messages package in its own workspace, build it with colcon build and then source the setup script of this workspace before building the create 3 examples package in another workspace.

Thank you. I'm only with ROS for a few months now creating very basic ROS2 nodes for my GoPiGo3 robot from scratch. Eager to learn about the Create3 ROS2 nodes created by folks that already understand ROS2.
