Revision history [back]

First of all thanks son much for your interest.

When I type rospack profile I´m given the next:

Full tree crawl took 0.390944 seconds. Directories marked with (*) contain no manifest. You may want to delete these directories. To get just of list of directories without manifests,

re-run the profile with --zombie-only

If I type echo &ROS_PACKAGE_PATH I´m given:

/home/pi/catkin_ws/src:/opt/ros/groovy/share:/opt/ros/groovy/stacks

May I have to do an export or something similar? In this case, how would be the semantics?

Maybe

export ROS_PACKAGE_PATH=/home/pi/catkin_ws/bosch_drivers/usb_cam:/opt/groovy/share ?

Sorry for my lack of knowledge and thanks you so much

EDIT 1:

I copied the bosch_drivers into my catkin_ws/src and did the catkin_make.

Now I can roscd usb_cam but when I do rosmake I'm given:

Configuring incomplete, errors occurred! -------------------------------------------------------------------------------} [ rosmake ] Output from build of package usb_cam written to: [ rosmake ] /home/pi/.ros/rosmake/rosmake_output-20140116-192405/usb_cam/build_output.log [rosmake-0] Finished <<< usb_cam [FAIL] [ 16.84 seconds ]
[ rosmake ] Halting due to failure in package usb_cam. [ rosmake ] Waiting for other threads to complete. [ rosmake ] Results:
[ rosmake ] Built 36 packages with 1 failures.
[ rosmake ] Summary output to directory
[ rosmake ] /home/pi/.ros/rosmake/rosmake_output-20140116-192405

And if I try rosrun usb_cam usb_cam_node I'm given :

[rosrun] Couldn't find executable named usb_cam_node below /home/pi/catkin_ws/src/bosch_drivers/usb_cam [rosrun] Found the following, but they're either not files, [rosrun] or not executable: [rosrun] /home/pi/catkin_ws/src/bosch_drivers/usb_cam/src/usb_cam_node

Could anyone help me please?
