I'll respond to this here as it relates to currently misleading documention.
You have done exactly what the docs said, but the docs should have told
you differently. Python scripts for ROS should in general be runnable
with rosrun, so they should not go into bin. Putting them into setup.py
as "scripts" will put them in the wrong place.
Instead, you may use cmake like this:
install(TARGETS scripts/foo_script
DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)
This will not put anything in the devel space, which is okay because
rosrun looks into the source folder as well.
Still you'd need to declare python packages in the setup.py, but then
those should be found, after sourcing devel/setup.*sh
That's how groovy catkin packages have done it so far.
A second possibility is to declare such scripts as data_files in the
setup.py files, like this:
setup(
...
data_files=[('lib/my_foo_package', ['scripts/foo', 'nodes/bar'])])
We'll probably make this the recommended way, but this solution is not
totally clean and confirmed yet, and will probably be made a bit more
convenient to type.
The discussion can be followed at the Buildsystem SIG here:
https://groups.google.com/d/topic/ros-sig-buildsystem/hsxeJocnKIQ/discussion
That's also the best place to respond to this post.
