Unable to run example.launch about mav_trajectory_generation HOT 3 OPEN

Was this ever solved?

from mav_trajectory_generation.

I'm receiving the same error message - any ideas?

from mav_trajectory_generation.

I looked into this a bit today. There's a small change to get it working:

Small change to
/home/counterswarm/catkin_newrotors/src/mav_trajectory_generation/mav_trajectory_generation_example/src/example_planner.cc

Line 133-134 converts the planned trajectory (cleverly named trajectory) to a PolynomialTrajectory type called msg
mav_planning_msgs::PolynomialTrajectory msg;
mav_trajectory_generation::trajectoryToPolynomialTrajectoryMsg(trajectory, &msg);

At line 137 msg is published
pub_trajectory_.publish(msg);

msg is a mav_planning_msgs/PolynomialTrajectory message type
While pub_trajectory_ is defined as a mav_planning_msgs/PolynomialTrajectory4D message type

Change msg to
mav_planning_msgs::PolynomialTrajectory4D msg;

Run catkin build and the example ran successfully for me.
