simple navigation goal [closed]

edit

I am trying to compile the simple_navigation_goals.cpp file from this tutorial.

http://wiki.ros.org/navigation/Tutori...

Steps i took:-

1) catkin_create_pkg simple_navigation_goals move_base_msgs actionlib roscpp

2) put the code in src folder

3) add_executable(simple_navigation_goals src/simple_navigation_goals.cpp) target_link_libraries(simple_navigation_goals ${catkin_LIBRARIES})

4) catkin_make

####

Running command: "make -j4 -l4" in "/home/administrator/catkin_ws/build"

#### Scanning dependencies of target simple_navigation_goals [100%] Building CXX object simple_navigation_goals/CMakeFiles/simple_navigation_goals.dir/src/simple_navigation_goals.cpp.o Linking CXX executable /home/administrator/catkin_ws/devel/lib/simple_navigation_goals/simple_navigation_goals [100%] Built target simple_navigation_goals

After that i did source catkin_ws/devel/setup.bash

rosrun couldn't find my simple_navigation_goals package

Any help ??

Answer:- i need to set the source of catkin workspace
