Error:cannot launch node [octomap_server/octomap_server_node]

edit

Hello I am trying to convert my point cloud data into map using octomap. I am newbie in this, so i would like to know what I am doing wrong. To create map these are steps I followed:

1. rosbag info<mypoint_cloudbagfile> : OUTPUT: gives all the required information appropriately
2. rosbag play <mypoint_cloudbagfile>
3. Created my own Package
4. Inside launch folder added this data: https://github.com/OctoMap/octomap_ma...
5. Updated Package.xml with required dependencies

6. Updated CmakeLists.txt like this:

   cmake_minimum_required(VERSION 2.8.3)
   project(octomap_server)
   
   
   
   set(PACKAGE_DEPENDENCIES
     roscpp
     rospy
     std_msgs
     pcl_ros
     pcl_conversions
     visualization_msgs
     nav_msgs
     octomap_ros
     octomap_msgs
     #dynamic_reconfigure
     nodelet
     sensor_msgs
   )
   
   
   find_package(catkin REQUIRED COMPONENTS ${PACKAGE_DEPENDENCIES})
   
   find_package(PCL REQUIRED QUIET COMPONENTS common sample_consensus io segmentation filters)
   
   find_package(octomap REQUIRED)
   
   include_directories(
    include
    $(catkin_INCLUDE_DIRS)
    $(PCL_INCLUDE_DIRS)
    $(OCTOMAP_INCLUDE_DIRS)
   )
   catkin_package(
     INCLUDE_DIRS include
     LIBRARIES ${PROJECT_NAME}
     CATKIN_DEPENDS ${PACKAGE_DEPENDENCIES}
     DEPENDS octomap PCL
   )
   
   set(LINK_LIBS
       ${OCTOMAP_LIBRARIES}
       ${catkin_LIBRARIES}
       ${PCL_LIBRARIES}
   )
   

7. ran launch file :

   roslaunch octomap_server octomap_mapping.launch
   

It runs but gives this error:

OUTPUT: ERROR: cannot launch node of type [octomap_server/octomap_server_node]: can't locate node [octomap_server_node] in package [octomap_server]

P.S.: I have already installed octomap_mapping using

sudo apt-get install ros-kinetic-octomap_mapping

Please tell me why this error occurs and how can I repair it to proceed in creating a map.

There are some solutions I tried: 1. run rosrun octomap_server octomap_server_node to check node

I got this output:

Couldn't find executable named octomap_server_node below /home/ubuntu/catkin/src/octomap_server

2. Source the bash file using:

source ~/catkin_ws/devel/setup.bash

Thank You!
