segmapper node : Roslaunch got a 'No such file or directory' error while attempting to run #20

Thanks @RozDavid for the work again, and I figured out I have a problem with segmapper node. when I launched the file name of kitti_loam_segmap.launch , the error occurs like this.

Roslaunch got a 'No such file or directory' error while attempting to run:

gdb -ex run --args /root/Catkin/LOL/devel/lib/segmapper/segmapper_node name:=segmapper log:=/root/.ros/log/697f507e-2b2a-11ec-bcd7-e86a64425b4b/segmapper-2.log

Please make sure that all the executables in this command exist and have executable permission. This is often caused by a bad launch-prefix. The traceback for the exception was written to the log file

so I tested launching the launch file without segmapper node, it goes well. Maybe only the LOAM I guess.

Any idea for this?

Sincerely, Jeff.

Hey @jeffkimkorea-git,

If you installation finished succesfully and you sourced your environment I suppose here shold be no error like this. Do you have xterm and gdb installed?

Maybe you coul try running both manually in a terminal or comment out the launch prefix from the segmaper_node.

Cheers, David

Installing gdb made that error clean! Thanks!

sudo apt-get install gdb
