Hello all;

I am starting with ROS, groovy version. I have managed to compile some code in a package using catkin, but the executables generated are placed ~/catkin_ws/devel/lib/package_name.

In my CmakeLists.txt I have used "add_executable" and "target_link_libraries"

I think the executables should be in ~/catkin_ws/devel/bin/package_name., instead under lib directory.

Is this correct? Where could I have the error?

Thank you all in advance,

Best Regards,

AFAIK this is correct and not an error at your side, although a bit ugly.

My guess is that this is used to not pollute the namespace in $PATH that adds bin/... and only run nodes via rosrun. A comment from the developers would be nice.

Not a developer, but I've been documenting catkin lately. Here's my current draft, which agrees with your answer: http://farnsworth.csres.utexas.edu/docs/catkin/html/howto/building_executables.html#installing

Thank you... If this is correct, as you say it is a bit confusing, where the real compiled libraries would de placed then?

Another problem arises with this. Now I am trying to launch one of these executables from a launch file using:

<node pkg="tekniker_pcl_io" name="RecordAllPcdFromTopic" type="RecordAllPcdFromTopic"/>

And I get this error: ERROR: cannot launch node of type [tekniker_pcl_io/RecordAllPcdFromTopic]: can't locate node [RecordAllPcdFromTopic] in package [tekniker_pcl_io]

Thank you in advance...
