Name.action catkin_make error

Hi @girishkumar.kannan @bayodesegun ,

I face this error in creating my custom action file. I check my ros install directory the “/noetic/share/rospy/cmake” is present but I don’t why catkin_make can’t find the msg path. Any help would be highly appreciated.

Name.action

#goal
std_msgs/Int32 goal
---
#result
std_msgs/Int32 result
---
#feedback
std_msgs/Int32 feedback

CMakelists.txt

cmake_minimum_required(VERSION 3.0.2)
project(my_custom_action_msg_pkg)


find_package(catkin REQUIRED COMPONENTS
  actionlib_msgs
  rospy
  std_msgs
)

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

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

The error msg in terminal

Action_error2
Action_error21920×1080 229 KB

I am really lost like why does get error in unit_5_services/CMakeLists.txt:10 (find_package) and what that has to do with the current pkg am working

Thank you,

I even tried Updating the CMakelist with message_generation in find package() and also updated it in package.xml with the 3 build depend but now I get a different error from another package.

Hi @balajigunasekeran22 ,

Please check your unit_5_services package. In the CMakeLists.txt file of that package, make sure you have included iri_wam_reproduce_trajectory package like below:

find_package(catkin REQUIRED COMPONENTS
  iri_wam_reproduce_trajectory
  rospy
)

That should (probably) solve your problem.

Also, I think you are using catkin_make
instead of catkin_make --only-pkg-with-deps <pkg_name>.

Let me know if your issue is solved.

Hello @girishkumar.kannan ,

Thank you for the reply. I solved the error for Name.action and the “rosmsg list | grep Name” shows me the expected results. However in this unit_5_services I have already included iri_wam_reproduce_trajectory but I don’t why that I shows errors only now and Not while I was in that package. Does this has anything to do with my deletion of the devel and build folder as it did to solve the error in Name.action

cmake_minimum_required(VERSION 3.0.2)
project(unit_5_services)


## is used, also find other catkin packages
find_package(catkin REQUIRED COMPONENTS
  #iri_wam_reproduce_trajectory
  iri_wam_reproduce_trajectory
  rospy
)


catkin_package(
#  INCLUDE_DIRS include
#  LIBRARIES unit_5_services
  CATKIN_DEPENDS iri_wam_reproduce_trajectory rospy
#  DEPENDS system_lib
)


## Specify additional locations of header files
## Your package locations should be listed before other locations
include_directories(
# include
  ${catkin_INCLUDE_DIRS}
)

Reagrds,
BG

Hi @balajigunasekeran22 ,

If you deleted your build and devel folder, the very first compilation after the folder deletion must be
catkin_make only - to build all the packages at once. You can also use --only-pkg-with-deps but that is only when you choose to compile packages individually.

But you must build your custom message package before compiling the package that uses the custom message package.

Hope this helps.

Regards,
Girish
