Revision history [back]

Hi Eric, thank you. I tried "rosmake --pre-clean sicktoolbox_wrapper" and it worked.

Here is the steps I followed.(In case any one is having trouble)

1) download sicktoolbox

2)rosmake sicktoolbox

3)open this file (your_ros_installation_directory)/ros/diamondback/stacks/sicktoolbox/build/sicktoolbox-1.0/c++/drivers/lms/sicklms-1.0/SickLMS.cc . Go to line 2319. 3) In this line, add the O_NDELAY flag as shown here:

if((_sick_fd = open(_sick_device_path.c_str(), O_RDWR | O_NOCTTY| O_NDELAY)) < 0) { throw SickIOException("SickLMS::_setupConnection: - Unable to open serial port"); }

4)After this line, add a system sleep call for 30 seconds. This is required so as to allow the sick laser to start up and start scanning.

sleep(30); // actually It worked fine for me without adding this line as well, but it didn't for my friend

5)go to ros/diamondback/stacks/sicktoolbox/build/sicktoolbox-1.0/c++/drivers/lms/sicklms-1.0/

and

$ make all 6)$rosmake sicktoolbax

7)$rosmake sicktoolbox_wrapper

8)rosmake --pre-clean sicktoolbox_wrapper

9) then continue with the tutorials

10)you should see the scan in RVIZ..

once again thank you Eric and all the best for for others.
