Rosrun can't find osrf_gear on kinetic, Ubuntu 16.04

kinetic

#1

I get the following error attempting to run per the instructions on the wiki:

rosrun osrf_gear gear.py -f `catkin_find --share osrf_gear`/config/comp_conf2.yaml ~/helloworld_ws/src/ariac_example/config/sample_gear_conf.yaml -o /tmp
[rospack] Error: package 'osrf_gear' not found

I have build osrf_gear from source. Here is the output of rospack profile after I source the setup.bash file in my ariac workspace cloned from bitbucket:

$ rospack profile

rospack find finds osrf_gear.

$ rospack find osrf_gear
/home/dheater/src/ariac_ws/src/osrf_gear

Hints as to why rosrun can’t seem to find the osrf_gear package?

Hi Daniel,

Can you post the output of catkin_find --share osrf_gear?


#3
$ catkin_find --share osrf_gear
 /home/dheater/src/ariac_ws/devel/share/osrf_gear
 /home/dheater/src/ariac_ws/src/osrf_gear

How did you build our software? It looks like you’re using a “devel space” (see http://www.ros.org/reps/rep-0128.html#development-space). You might try installing and using the install space, as that’s what I did most of my testing with. If there is an issue with the devel space we should fix it, but using the install space might be a good workaround in the meantime.


#5

Yep. I was using the development space. I installed using catkin_make install -DCMAKE_INSTALL_PREFIX=/opt/ros/kinetic and its finding osrf_gear now.

Thanks!

Cool, I’ll open an issue to track the devel space problem:

Also, I’d recommend using a local install location, i.e. simply don’t specify CMAKE_INSTALL_PREFIX and it will default to a folder called install next to the src and build folders.

I don’t recommend installing to /opt, but you can if you know what you’re doing :smile:.
