Mar 20, Create build. Apr 4, Update pkglist-ros. Mar 21, I'm interested in working with rclcpp, so I've decided to install ROS2 Dashing by building it from source, on a system with a fresh upgrade to Ubuntu I am using this guide from ros. However, I simply cannot manage to successfully build ROS2. The following problems I have encountered are:. Install development tools and ROS tools : I was unable to succesfully run sudo apt install python3-colcon-common-extensions.
It returned with E: Unable to locate package python3-colcon-common-extensions. Workaround : I obtained colcon using pip3 install -U colcon-common-extensions. I then added it to my PATH environment variable. I was able to install python3-lark-parser through pip3 however, and hoped that sorted out the problem.
After this I was unable to do anything to try and repair my installation. I unfortunately feel a bit overwhelmed by the amount of dependencies and what I perceive to be the complexity of the ROS2 build process. Additionally: I simply defaulted to Dashing as it was the distribution I've used in the past, but only via a docker image.
I realize it is now illogical of me to have paired an older version of ROS with a newer unsupported version of Ubuntu. I can attempt to reinstall an older version of Ubuntu and repeat the procedure with a new version of ROS, but I'd rather avoid that if possible. I would still recommend trying Eloquent, as I expect this to be the first thing you'll get as a question from the maintainers. The other "23 packages with stderr output" should also get some attention, but focusing on one package first would Note that for Eloquent you will also have to install python packages by hand as they are not available from debs:.
I also had to substitute:. For now things seem okay. I will update this if I find there are problems with the build after. Thank you all so far for your assistance in getting this installed correctly. I really appreciate it!

At the time of writing ROS2 Dashing is the latest release available. We will install the Desktop version that includes also the demos. After installing is worth checking that it went fine by running one of the examples.
We can see that the messages published by the talker node in terminal 1 are received by the listener node in terminal 2. In its present state ROS2 is not currently capable of achieving hard RT due to the number of changes that are yet to be developed by the community.
Nevertheless, some support for realtime is already included in the distribution and a demo of an inverted pendulum control is available.
We can try to run the default demo by:. The pendulum demo depends on the rttest library to compile and run. In order to be able to run the demo in the Hikey we need to modify the memory requirements to fit the 6GB RAM available on the Hikey We can then modify the memory allocation lines and from:.
This change leads to approximately 1.
So we can now compile the modified package and re-run the pendulum demo:. We will assess how both DDS implementations perform on the pendulum demo. First we need to get the Eclipse Cyclone DDS and build it, which is pretty straighforward following the steps in its rmw repository. We will use the ROS2 workspace that we created to modify the rttest library:. Apart from this, the latency for both DDS implementations is well below the maximum allowed for the system.
Further investigation would be needed to identify the different behaviour of the DDS implementations on subsequent runs of the demo, which is out of scope of this initial test. Although there are a number of items that still need to be addressed to get a fully real-time compatible system using ROS2, these first steps allow to start developing soft real-time applications using 96boards hardware and ROS2.

Please install ROS2 via the usual build instructions for your desired distribution. Note: You need to change --rosdistro to the selected ROS 2 distribution name e. Ensure there are no ROS environment variables set in your terminal or.
The three workspaces are:. When building ROS 2 from source, make sure that the ros2. First, source the setup. Then, use vcs to clone the repos and versions in it into a workspace. Finally, now that we have ROS2 master and the necessary dependencies, we can now build Navigation2 master itself.
The rest of this should look familiar. There are 2 options for docker with Navigation2: building a container and using the DockerHub container. To build an image from the Dockerfile in the navigation2 folder: First, clone the repo to your local system or see Building the source above. Note: You may also need to configure your docker for DNS to work.

Install argcomplete optional. Install additional RMW implementations. Install additional packages using ROS 1 packages. Build your own packages. Make sure you have a locale which supports UTF If you are in a minimal environment, such as a docker container, the locale may be something minimal like POSIX. We test with the following settings. You will need to add the ROS 2 apt repositories to your system. To do so, first authorize our GPG key with apt like this:. No GUI tools. ROS 2 command line tools use argcomplete to autocompletion.
So if you want autocompletion, installing argcomplete is necessary. In another terminal source the setup file and then run a Python listener :. See the tutorials and demos for other things to try. University, purchase or evaluation options are also available for RTI Connext.
To be able to install them please start by adding the ROS 1 sources as documented here. This will also avoid the need to setup the ROS sources as they will already be integrated.
If you would like to build your own packages, refer to the tutorial "Using Colcon to build packages". Troubleshooting techniques can be found here. If you need to uninstall ROS 2 or switch to a source-based install once you have already installed from binaries, run the following command:.

Writing an Action Server Python.This article is a design proposal for developing a ROS 2 tool that sets up and manages sysroot environments for cross-compilation with the objective of being simple and extensible.
Extending support for new cross compilation configurations using colcon mixins is also proposed. That command should also be implemented using an extensible design that allows supporting new platforms with low effort. We propose continuing with the general approach of the cross-compilation tutorial. We propose adding a set of commands to wrap the instructions in the cross-compilation tutorial. These commands would use a new workspace directory for the target platform, determined by a convention based on the:.
Let us call this workspace directory the cc-root. To implement the proposal, we would add the following commands:. Under the hood, the create-cc-sysroot command would do the following:.
The create-cc-sysroot command will also support the following optional arguments:. Support for other platforms can be added by creating corresponding ROS 2 Docker images, and variants of the toolchain file if required. Regarding maintenance, in order to support cross-compilation for a new platform we would need to:.
In order to simplify the development of base ROS 2 Docker images for new architecture-OS combinations, on a future iteration of this initiative we might add a new command build-sysroot-base-image that would:. The proposed design leads to a simple development experience, where cross compilation is triggered by two simple commands, or a single cc-build command for the second iteration.
The design is extensible and new platforms can be supported easily. For simple packages with additional dependencies, there is no need to build the sysroot locally with Docker, and a readily available base Docker image can be used. This setup is focused on cross-compiling for Linux based platforms. On the other hand, a Windows or Mac development workstation could use this build setup, running the build commands inside a Docker container, although that would imply some performance degradation due to the virtualization layer that Docker employs on those platforms.
We should determine a process for building and publishing the base ROS 2 Docker images for each platform. Ideally a nightly job would publish an image built from source for the tip of master, but that might be not feasible depending on the available resources. The colcon bundle plugin can be used to package a ROS workspace together with all its dependencies into a tarball.
That could be used for cross-compiling a ROS 2 workspace by launching a Docker container for the target platform, building and bundling the workspace, and exporting the bundle, which can then be deployed to the target hardware. The main drawback of that approach is that using the default ARM compiler in the Docker image significantly slows down the compilation, which might be a burden for day-to-day development.
In practice, it lets you run ARM binaries on your X86 instance, as it is done implicitly through Docker when building the base image. That would provide a way to distribute cross-compiled system dependencies, which is convenient because rosdep install can take a lot of time on resource constrained hardware, and requires an Internet connection.
The presented approach and colcon bundle are complementary approaches, and if colcon bundle eventually supports ROS 2, we could use cc-build for easy cross-compilation minimizing the usage of Docker, followed by colcon bundle to generate a deployable artifact.
Regarding the workspace dependent sysroot image, we could avoid the Docker COPY of the workspace by not building a workspace sysroot image, and instead launching a container for the base ROS 2 image with a bind mount for the workspace.
That image would be useful for running tests, as mentioned in the testing section above, and an eventual cc-test command could further simplify using that image.
