Hi,

After clonning the repository, given in the leg_detector ros.org page, to my catkin workspace and after performing the cakin_make I get the following error:

[ 98%] Linking CXX executable /home/joao-nisa/catkin_ws/devel/lib/face_detector/face_detector

I've installed the Melodic version of ROS and the version of OpenCV is the 3.4.0. Can anyone help me solving this problem?

Thanks in advance!

It looks like it will either work or not work depending on whether you have this PR. Try rolling it back (or checking out the kinetic branch).

Thanks, that worked!

However, when I launch the leg_detector I get the following error:

[ WARN] [1564669364.430665292]: MessageFilter [target=odom ]: Dropped 100.00% of messages so far. Please turn the [ros.leg_detector.message_notifier] rosconsole logger to DEBUG for more information.

I changed the bagfile to the following:

<launch>
  <node pkg="leg_detector" type="leg_detector" name="leg_detector" args="scan:=base_scan $(find leg_detector)/config/trained_leg_detector.yaml" output="screen">
    <param name="fixed_frame" type="string" value="odom"/>
  </node>
</launch>

Because, before I change my bagfile to what is presented above, I got the same error but target instead of odom was odom_combined.

But as you can see, that doesn't seem to work.

How can I get the detection results?

Thanks in advance @David Lu

Rolling back to 9fcbc87 commit helped, not to origin/kinetic branch.
