Unable to create action message

Hi !

I am unable to create a Action message for final quiz . I have followed the whole procedue 3-4 time but still its not create the action messge. I have added the cmakelists and package code below.

Cmake lists :

cmake_minimum_required(VERSION 3.0.2)

project(actions_quiz)

Compile as C++11, supported in ROS Kinetic and newer

add_compile_options(-std=c++11)

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

actionlib_msgs

std_msgs

)

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

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 exec_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 exec_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 …)

* 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

Message1.msg

Message2.msg

)

Generate services in the ‘srv’ folder

add_service_files(

FILES

Service1.srv

Service2.srv

)

Generate actions in the ‘action’ folder

add_action_files(

FILES

CustomActionMsg.action

)

Generate added messages and services with any dependencies listed here

generate_messages(

DEPENDENCIES

actionlib_msgs std_msgs

)

################################################

Declare ROS dynamic reconfigure parameters

################################################

To declare and build dynamic reconfigure parameters within this

package, follow these steps:

* In the file package.xml:

* add a build_depend and a exec_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 dynamic reconfigure parameters in the ‘cfg’ folder

generate_dynamic_reconfigure_options(

cfg/DynReconf1.cfg

cfg/DynReconf2.cfg

)

###################################

catkin specific configuration

###################################

The catkin_package macro generates cmake config files for your package

Declare things to be passed to dependent projects

INCLUDE_DIRS: uncomment this if your package contains header files

LIBRARIES: libraries you create in this project that dependent projects also need

CATKIN_DEPENDS: catkin_packages dependent projects also need

DEPENDS: system dependencies of this project that dependent projects also need

catkin_package(

INCLUDE_DIRS include

LIBRARIES actions_quiz

CATKIN_DEPENDS actionlib_msgs std_msgs

DEPENDS system_lib

)

###########

Build

###########

Specify additional locations of header files

Your package locations should be listed before other locations

include_directories(

include

${catkin_INCLUDE_DIRS}

)

Declare a C++ library

add_library(${PROJECT_NAME}

src/${PROJECT_NAME}/actions_quiz.cpp

)

Add cmake target dependencies of the library

as an example, code may need to be generated before libraries

either from message generation or dynamic reconfigure

add_dependencies(${PROJECT_NAME} ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})

Declare a C++ executable

With catkin_make all packages are built within a single CMake context

The recommended prefix ensures that target names across packages don’t collide

add_executable(${PROJECT_NAME}_node src/actions_quiz_node.cpp)

Rename C++ executable without prefix

The above recommended prefix causes long target names, the following renames the

target back to the shorter version for ease of user use

e.g. “rosrun someones_pkg node” instead of “rosrun someones_pkg someones_pkg_node”

set_target_properties(${PROJECT_NAME}_node PROPERTIES OUTPUT_NAME node PREFIX “”)

Add cmake target dependencies of the executable

same as for the library above

add_dependencies(${PROJECT_NAME}_node ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})

Specify libraries to link a library or executable target against

target_link_libraries(${PROJECT_NAME}_node

${catkin_LIBRARIES}

)

#############

Install

#############

all install targets should use catkin DESTINATION variables

See http://ros.org/doc/api/catkin/html/adv_user_guide/variables.html

Mark executable scripts (Python etc.) for installation

in contrast to setup.py, you can choose the destination

catkin_install_python(PROGRAMS

scripts/my_python_script

DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}

)

Mark executables for installation

See http://docs.ros.org/melodic/api/catkin/html/howto/format1/building_executables.html

install(TARGETS ${PROJECT_NAME}_node

RUNTIME DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}

)

Mark libraries for installation

See http://docs.ros.org/melodic/api/catkin/html/howto/format1/building_libraries.html

install(TARGETS ${PROJECT_NAME}

ARCHIVE DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}

LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}

RUNTIME DESTINATION ${CATKIN_GLOBAL_BIN_DESTINATION}

)

Mark cpp header files for installation

install(DIRECTORY include/${PROJECT_NAME}/

DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}

FILES_MATCHING PATTERN “*.h”

PATTERN “.svn” EXCLUDE

)

Mark other files for installation (e.g. launch and bag files, etc.)

install(FILES

# myfile1

# myfile2

DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION}

)

#############

Testing

#############

Add gtest based cpp test target and link libraries

catkin_add_gtest(${PROJECT_NAME}-test test/test_actions_quiz.cpp)

if(TARGET ${PROJECT_NAME}-test)

target_link_libraries(${PROJECT_NAME}-test ${PROJECT_NAME})

endif()

Add folders to be run by python nosetests

catkin_add_nosetests(test)

<?xml version="1.0"?>

What you have posted here is totally unreadable. But you don’t need to post the codes here.

Please go over the instructions again. If you have created custom messages in the exercises before the quiz, and you should have, you need to just follow the same procedure to create the one for the quiz taking note of the differences in the names.

Now when you say the action message was not created, how do you know that? What commands have you run to check?

After following all the instructions , when did these instruction it did not output the my custom message :

roscd; cd …
catkin_make
source devel/setup.bash
rosmsg list | grep Name

I was confused , but after deleting build folder and rerunning the procedure it worked :+1:
