The common thread that ties all of these systems together is the division of the code into packages, with each package containing a manifest file ( manifest.xml or package.xml).
CMAKE INSTALL PREFIX REMAINTS FULL
Provide a tool that can be used to iterate in dependency order over a workspace full of packages, building and perhaps installing each one.Ĭatkin: catkin build, catkin_make, catkin_make_isolated, etc. Rosbuild: mk/cmake.mk, rosbuild_init(), rosbuild_add_executable(), etc.Ĭatkin: catkin_package(), catkin_install_python(), etc.Īment: ament_target_dependencies(), ament_export_dependencies(), ament_package(), etc. There are usually hooks to allow injection of extra API by packages outside of the core meta-build system.

CMake) that can be used to simplify common tasks (e.g., supplying all the flags exported by depended-upon packages when building an executable). They sit atop other build systems (e.g., CMake, Python setuptools) and provide extra functionality that’s intended to make those build systems easier to use, especially when managing dependencies across multiple packages and when building multiple packages in a single workspace.Įach of these meta-build systems does two things:Īdd API to the underlying build system (e.g. Recently introduced is a thing called ament, which may one day replace catkin.Īll three tools can be considered “meta-build systems.”

Then came a thing called catkin, which largely replaced rosbuild.
