Hello!!! I am doing the ROS tutorials for indigo in ubuntu 14.04 and in Creating a ROS msg and srv when trying to do

> catkin_make install

I get this error

CMake Error at /opt/ros/indigo/share/genmsg/cmake/genmsg-extras.cmake:197 (message):
  generate_messages() must be called before catkin_package() in project
  'beginner_tutorials'
Call Stack (most recent call first):
  beginner_tutorials/CMakeLists.txt:73 (generate_messages)

This is my CMakeLists.txt

cmake_minimum_required(VERSION 2.8.3)
project(beginner_tutorials)

## Compile as C++11, supported in ROS Kinetic and newer
# add_compile_options(-std=c++11)

## Find catkin macros and libraries

find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  message_generation    
)

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

## Declare ROS messages, services and actions ##
################################################

## To declare and build messages, services or actions from within this
## package, follow these steps:
## * Let MSG_DEP_SET be the set of packages whose message types you use in
##   your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
## * In the file package.xml:
##   * add a build_depend tag for "message_generation"
##   * add a build_depend and a run_depend tag for each package in MSG_DEP_SET
##   * If MSG_DEP_SET isn't empty the following dependency has been pulled in
##     but can be declared for certainty nonetheless:
##     * add a run_depend tag for "message_runtime"
## * In this file (CMakeLists.txt):
##   * add "message_generation" and every package in MSG_DEP_SET to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * add "message_runtime" and every package in MSG_DEP_SET to
     catkin_package(

        CATKIN_DEPENDS message_runtime 
         )
##   * uncomment the add_*_files sections below as needed
##     and list every .msg/.srv/.action file to be processed
##   * uncomment the generate_messages entry below
##   * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)

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

## Generate services in the 'srv' folder
 add_service_files(
   FILES
   AddTwoInts.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
 )

## To declare and build dynamic reconfigure parameters within this

## * In the file package.xml:
##   * add a build_depend and a run_depend tag for "dynamic_reconfigure"
## * In this file (CMakeLists.txt):
##   * add "dynamic_reconfigure" to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * uncomment the "generate_dynamic_reconfigure_options" section below
##     and list every .cfg file to be processed

generate_messages() must be called before catkin_package()

the error is pretty clear: you have a catkin_package(..) call before your call to generate_messages(..). That is not going to work.

The first call to catkin_package(..) (in the comment block under Declare ROS messages, services and actions) is actually not supposed to be there. The comment block merely explains the steps that you need to perform to enable message & service generation.

You should not uncomment that catkin_package(..) line there. Rather, you should add what is described there to the catkin_package(..) call that appears somewhat later in the file (under the catkin specific configuration heading).
