ros run couldn't find executable file after catkin build and source

I'm trying to run an executable, but I'm getting the following error, I ran

catkin build

and then

source ~/emvs_ws/devel/setup.bash

after this running the following command shows this message

rosrun mapper_emvs run_emvs

the error is

[rosrun] Couldn't find executable named run_emvs below /home/ubuntu/emvs_ws/src/rpg_emvs/mapper_emvs

this is the cmake file:

project(mapper_emvs)
cmake_minimum_required(VERSION 2.8.3)

Solution

  • I'm not that experienced with catkin build, but I'm glad that catkim_make fixed your problem.

    Answering your second question, it means that this header file incremental_registration.h is not on the place your program is looking for it. However, I suggest you to close this question and create another one since they are not related.
