setting up a proper catkin workspace

[saimanoj18]

Hi,

First of all, its a great work and congratulations on that!

Now, I followed the installation instructions on the github and got it to work. Specifically,

1. I already have a ubuntu 14.04 with ROS Indigo and tried to install the source code in catkin_ws/src/ but was having some issues producing compiling erros, hence
2. I created a new folder and catkin_ws_segmatch and I followed the instruction on github and later i could get both localization and loop closure to work.
3. Once I close the terminal and open a new terminal and try to replicate the steps then, it produces an error saying

ERROR: cannot launch node of type [laser_mapper/laser_mapper_node]: can't locate node [laser_mapper_node] in package [laser_mapper]

I tried adding adding the line shown below in .bashrc file but it didnt help. _export ROS_PACKAGE_PATH=/home/iirav/catkin_ws_segmatch/src:/home/iirav/catkinws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks

Could you help in solving this issue ?

Have you tried sourcing your new workspace before running segmatch? source ~/catkin_ws_segmatch/devel/setup.bash

However, this is not really a segmatch issue but rather a general catkin question on how to work with multiple workspaces. If my suggestion doesn't fix your problem consider asking this issue in a more appropriate place.

That worked perfectly! Thanks.
