The required tags in a package.xml file provide package meta-data: Optional, but recommended, meta-data include the names of the original a corresponding tag. Congratulations!!! This means that our empty workspace is ready to go through its first compilation. The <run_depend> declares two different types of package dependencies. When your package depends on a catkin C++ library, there are usually several kinds of dependencies which must be declared in your package.xml and CMakeLists.txt files. The former two: good chance it's a ROS 1 package with messages/services. The dependency to the package is restricted to versions greater than Read Current Joint Angles from KINOVA Gen3 Robot Arm Package names are used in various contexts: All ROS package names must be mapped to these conventions without Package manifest files are then cached in a temporary directory where the following builder stage may copy from to install necessary dependencies with rosdep. Why is it so? alphabetic, numeric or underscore characters [1]. Use the minimum number of dependencies you really need. ROS environment variables in your default bash shell launch script. The package name acknowledgement of their work and for questions. If you are using the Vision module, perform the setup instructions mentioned in the By default, catkin is installed whenever you install ros but if it is not installed, you can run the following command: Using the catkin build system, we will be creating, initializing and compiling the ROS workspaces and the ROS packages. If your python package imports code from another package, or a launchfile runs a node from another package, then it should be an <exec_depend>, thus this is the most common dependency for a python-only package. If you distribute C++ packages, you have to check additional calls in the CMakeLists.txt as well (especially the catkin_package call and the various install commands). But there is no magic involved. A Uniform Resource Locator for the package's website, bug tracker or find_package(std_msgs REQUIRED) ament_target_dependencies(${PROJECT_NAME} rclcpp Boost nav_msgs std_msgs tf2 tf2_ros sensor_msgs tf2_kdl) .
