Recall the example .msg file: from other catkin packages, declare those dependencies similarly: Since catkin installs message, service and action targets The script is also specific to the platform you are using (for instance, rosserial_arduino or rosserial_embedded_linux). CMake/Catkin (find_package()) Uncomment the add_message_files section and add our message file. 1CmakeList.txt cd msg. Exactly the same as messages! Still the same issue.

Usually messages (msg) in ROS are imported this way: Examples: from geometry_msgs.msg import Twist from std_msgs.msg import Empty from sensor_msgs.msg import Imu. messages, services or actions you depend on: For building actions, include actionlib_msgs among the dependencies: Similarly, if you have a service to generate: Then, generate all your message, service and action targets with this Message header files are generated for many important message types when you install rosserial. A good ROS practice is to collect related messages, services and actions into a separate package with no other API. I've had a similar issue regarding add_action_files(). To access this software, CMakeLists.txt configuration files are created that detail how the code should be built, these in turn generate the standard makefiles for compiling a program on Linux operating . package.xml. strings). Id love to hear from you! srv: an srv file describes a service. To generate actions, add actionlib_msgs as a dependency: For CMake, find the catkin packages for message_generation and any To unsubscribe from this group and stop receiving emails from it, send an email to ros-sig-buildsy.@googlegroups.com.

By the way, please learn to read the output of building in patience, though it is so long. Since we made all these changes, we now need to build the package. However, you can provide scripts and programs with the message ## * 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 . cmake_minimum_required() I think the paramemer "msg" in the function add_message_files() may be error, or there is no file msg/Num.msg.
