Can someone explain why? To generate actions, add actionlib_msgs as a dependency: For CMake, find the catkin packages for message_generation and any I recently installed ROS indigo and following the tutorial to get to know ROS. command: Make sure the catkin_package() command declares your message, add_message_filespackage_name/src.msg.msgpackage_name/src/msg, .msgpackage_name/msg/CMakeLists.txt, eeew9527: If you need to use other message types, or you have your own custom message types, you will need to generate the appropriate headers. , They are used to generate source code for messages in different languages. (project()) First of all, from command line, enter the package folder exploiting the roscd ROS command: roscd custom_msgs. this: The
tag is recommended for message dependencies. Otherwise, create your own ROS2 custom message. Recall the example .msg file: I tried commenting message in CMakeslists file at first. from other catkin packages, declare those dependencies similarly: Since catkin installs message, service and action targets Specifically, we have declared three signed 32-bit integers. or indirectly uses one of your message headers must declare an That explicit dependency: If your build target also uses message or service headers imported Eligible message field types. cd msg. Your package.xml must declare a on cmake_minimum_required() In fact, try remove both /devel and /build, then try compiling again.Or, you could try move your package out from /catkin-dev/src/, remove \buid and \devel, compile, then move back your project and try compiling again.In my case I had to always set the flag to flase in the first compilation.. Python (catkin_python_setup()) Standard primitive types (integer, floating point, boolean, etc.) 1-1. Lets see how we can create our own custom messages in ROS.
