I wrote a service but is not showing up when I'm trying to call it. I've modified both my CMakelist and my package.xml but not luck. What am I missing. Here's my service:


sensor_msgs/NavSatFix latitude sensor_msgs/NavSatFix longitude

The following are my CMakelist and my package.xml

cmake_minimum_required(VERSION 2.8.3)
project(testerinfo)

## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  message_generation
  testerinfo
)

## System dependencies are found with CMake's conventions
# find_package(Boost REQUIRED COMPONENTS system)


## Uncomment this if the package has a setup.py. This macro ensures
## modules and global scripts declared therein get installed
## See http://ros.org/doc/api/catkin/html/user_guide/setup_dot_py.html
# catkin_python_setup()

## Generate messages in the 'msg' folder
# add_message_files(
#   FILES
#   Message1.msg
#   Message2.msg
# )

## Generate services in the 'srv' folder
 add_service_files(
   FILES
#   Service1.srv
#   Service2.srv
   locationFix.srv
 )

## Generate actions in the 'action' folder
# add_action_files(
#   FILES
#   Action1.action
#   Action2.action
# )

## Generate added messages and services with any dependencies listed here
# generate_messages(
#   DEPENDENCIES
#   std_msgs
# )

Also: please remove all boilerplate comment sections from both your CMakeLists.txt and your package.xml. It will make your question a bit easier to read.

Try uncommenting the section that begins with "## Generate added messages and services with any dependencies listed here".

I had a similar error here. After checking the tutorial details lots of times it was still happening (on Hydro, Ubunto14.04). I saw the output of catkin_make like this

-- ~~  traversing 1 packages in topological order:
-- ~~  - maps_ibex
-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-- +++ processing catkin package: 'maps_ibex'
-- ==> add_subdirectory(maps_ibex)
-- Using these message generators: gencpp;genlisp;genpy
-- maps_ibex: 0 messages, 2 services
-- Configuring done
-- Generating done
-- Build files have been written to: /home/charles/Dropbox/catkin_base/src

which claims the services are seen and generating has been done. but there was nothing in catkin_ws/devel/lib/python2.7/dist-packages/maps_ibex/srv/

After some experimentation -- I found the python files are created there if I do

cd src
make

No idea why this occurs though, looks like catkin_make is creating the CMake and Makefiles but then not actually running make?

I think you'd better open a new question. Please include your CMakeLists.txt and your package.xml.
