Building on OS X Mavericks... about hector_quadrotor HOT 5 OPEN

I just build another workspace, this time with hector_quadrotor and ros_controllers. I got the same errors. I'm not sure why I get the last error message about the plugins.

BTW, I'm preparing an environment for a new quadrotor called Spiri.

--Rasit

from hector_quadrotor.

rosinstall_generator downloads the sources from the release repositories which does not contain the latest commits. Furthermore the new workspace will contain all dependencies, including core ROS packages that are already installed in /opt/ros/hydro.

You should...

1. add --exclude RPP to exclude any package that is already available in your ROS_PACKAGE_PATH. Make sure that /opt/ros/hydro/setup.sh has been sourced before.
2. not use rosinstall_generator if you want to fetch the latest development versions. There is a --upstream-development option for rosinstall_generator that normally would work, but upstream information for the hector repositories is currently not available since ros/rosdistro#5057.

Instead, you can use the rosinstall file in the hector_quadrotor repo itself to create a workspace with hector_quadrotor and all its hector_* dependencies:

wstool init -t src https://raw.githubusercontent.com/tu-darmstadt-ros-pkg/hector_quadrotor/hydro-devel/hector_quadrotor.rosinstall

or

wstool init -t src https://raw.githubusercontent.com/tu-darmstadt-ros-pkg/hector_quadrotor/hydro-devel/tutorials.rosinstall

The tutorials.rosinstall file additionally contains hector_slam, which is only required for the SLAM demos.

To check (and/or install) additional requirements you can use rosdep:

rosdep <check|install> --from-path src --ignore-src

This command will show/install all missing dependencies that are not in the src/ folder and not in the ROS_PACKAGE_PATH.

Thanks for the detailed explanation.

I followed your instructions to install hector_* with the rosinstall
from the hector_quadrotor repo, but wstool complained about the -t option.
Also, rosdep check ... gives:

System dependencies have not been satisified:
homebrew ros/hydro/ros_control
homebrew ros/hydro/hector_slam
homebrew ros/hydro/gazebo_ros_pkgs
homebrew ros/hydro/joystick_drivers

Those packages are not available with homebrew. Shoud I install them
with rosinstall, instead?

What am I missing here?

Regards,

--Rasit

Well, it turned out that mixing hector_* development versions does not go well with other ros hydro repositories. I've tried a few things, some perhaps, stupid, but got stuck with:
Cannot use the aerodynamics model as the required plugin has not been
found. Try to run 'rosmake hector_quadrotor_gazebo_plugins' first.

I looked at the install_isolated/lib directory and the lib is there:
libhector_quadrotor_aerodynamics.dylib

somehow, it cannot be found.

Sorry for the delay. I cannot help you very much with MacOS related problems as I cannot reproduce them here. Have you found a solution in the meantime?

Here are some more general remarks that might help:

• Please update to the latest commit in hector_quadrotor and try again. Especially the latest patch 8845379 might have fixed the problem on MacOS.
• There are two libs, hector_quadrotor_aerodynamics (the model itself) and hector_quadrotor_aerodynamics (the Gazebo plugin that simulates aerodynamic forces). The error message mentioning rosmake was outdated and has been removed.
