11/23/2023 0 Comments Bazel vs cmakeThe improvements made by catkin_make_isolated come at a cost of speed however. This decoupling of dependencies allows catkin_make_isolated to build plain CMake packages, build packages without re-configuring dependencies, and to build part of a workspace. Since each package is treated as a separate CMake project, catkin_make_isolated processes all packages in the workspace sequentially and installs each package separately according to the dependency order. The install artifacts of a single package can therefore be removed by simply deleting its directory. Optionally, the install targets can be invoked by running catkin_make install and an install folder will be automatically created.Ĭatkin_make_isolated improves on catkin_make by building isolated workspaces (each software package is independently configured, built and installed into its own directory) instead of a merged workspace (every software package is installed into the same directory).A build folder (where cmake and make are invoked and the build files and intermediate build products are stored) and a devel folder (where generated files, targets and setup.*sh files are stored) will be created. Build the workspace using catkin_make -j2 VERBOSE=1 which will go through all the catkin projects found in the workspace src folder.Check that system dependencies are met by running rosdep update to update the dependencies database and rosdep -y install -from-paths src -ignore-src to attempt to install missing dependencies.To build a workspace using c atkin_make follow these steps: ROS packages that use the catkin build system will contain a package.xml file. An error in a leaf package (without dependencies) will also prevent all packages from configuring. Limitations of catkin_make include not being able to process plain CMake packages and requiring all targets (across all packages in a workspace) to be unique. The entire workspace is treated as a single CMake project which makes incremental builds faster but it is slow if build files need to be regenerated. catkin_make is a convenient way to evoke calls to cmake and make in the standard CMake workflow. Most ROS users are comfortable using catkin_make to build ROS workspaces since this is the command used in most tutorials. ![]() To build packages using rosbuild, simply run rosmake. This file contains useful information such as the cpp cflags and a list of dependencies. If a ROS package contains a manifest.xml file, then it uses the rosbuild system. Most commonly used ROS packages have been updated to use the recommended catkin build system. The CMake wrapper script ( rosmake) is what builds ROS. ![]() ![]() Rosbuild is a set of scripts for managing the CMake based build system for use with ROS. This article reviews build systems in the order they have been used within the ROS ecosystem, ending with colcon which is currently the latest ROS build system. The suggestion is to use catkin_make_isolated instead. ![]() The figure below shows the orocos_kdl package is plain cmake (it contains a manifest.xml file) thus it cannot be built using catkin_make. The motivation for this article is an error encountered while attempting to build a workspace containing both catkin and rosbuild packages. ROS build systems are built on top of CMake and have evolved over the years to simplify software development in robotics. CMake is a powerful open-source cross-platform set of tools designed to build, test and package software. A meta-build system like CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice. A build systems is a functional program or scripts developed to automate and simplify compiling and linking source code.
