Seeking clarity regarding the 'node' tag in launch files
I have added the following lines in the CMakeLists.txt file -
add_executable(abcd src/main.cpp)
target_link_libraries( abcd ${catkin_LIBRARIES} )
The node tag inside my launch file looks like this -
<node pkg="my_explore_lite" type="explore_node" respawn="false" name="abcd_1" output="screen">
...
</node>
As per my understanding, the value of type should be equal to abcd because that's what I have defined in the CMakeLists.txt. However, my launch file gets executed when I set the value of type to either abcd or explore_node.
What am I missing?
Did you previously build the node with the
explore_nodename (ieadd_executable(explore_node src/main.cpp))? If so it still exists in your built executables even if you change the name in the CMakeLists.txt. Try deleting your build and devel folders, rebuild, and see if you can still launch with theexplore_nodename.Yes. I did previously use
add_executable(explore_node src/main.cpp). Do you want me to delete thebuildfolder inside my package (~/catkin_ws/src/my_explore_lite/build) or you do want me to delete thebuildanddevelfolders at thecatkinworkspace root(~/catkin_ws/buildand~/catkin_ws/devel)?You should only have
buildanddevelfromcatkin_makeorcatkin buildin your workspace root. If thebuildfolder in your package came from catkin, then you may have ran it in the wrong directory. If you are sure thebuildfolder in your package came from catkin then delete it. Otherwise it may be part of a locally installed dependency and it should stay.Okay. Thanks!
