Hi, I am using this project with ros-melodic. After building i sourced the "tuw_marker_detection/tuw_aruco/build/devel/setup.bash" Then after running "rosrun tuw_aruco aruco_node", i got error-

[rosrun] Couldn't find executable named aruco_node below /home/rahul/tuw_marker_detection/tuw_aruco [rosrun] Found the following, but they're either not files, [rosrun] or not executable: [rosrun] /home/rahul/tuw_marker_detection/tuw_aruco/build/devel/lib/tuw_aruco/aruco_node

Any suggestion? Thanks.

Can you try to run it without rossrun within the /home/rahul/tuw_marker_detection/tuw_aruco/build/devel/lib/tuw_aruco/ folder

cd /home/rahul/tuw_marker_detection/tuw_aruco/build/devel/lib/tuw_aruco/
./aruco_node

Hi, I ran simple ./aruco_node then it just gets hang displaying nothing in terminal.

If the executable can not be found you have to check your build system. And do not forget to start the roscore first

Hi, I have started the roscore already. And i can found aruco_node in "tuw_marker_detection/tuw_aruco/build/devel/lib/tuw_aruco/" folder.

Is there any output expected by ./aruco-node?

I have the same problem, did you solve it?

Duplicate of #5

@rahulsharma11 there is no output on stdout or err for aruco_node at the moment. If you have no core running it will print an error. I will consider printing a status message so it's easier to identify if it's running. By itself at the moment the node will just output messages which you could monitor with rostopic echo if a marker is found.
