Release to Ubuntu 22.4 / jammy

[doisyg]

Now that ubuntu 22.04 is out, would it be possible to get updated binaries or if they are the same to update the debian repo ?

[MartyG-RealSense]

Hi @doisyg The librealsense SDK currently officially supports up to Ubuntu 20.04 (Focal) at the time of writing this. Support for newer Ubuntu versions will be announced at a future date.

You should be able to attempt to build the SDK from source code with CMake for Jammy immediately though if the SDK is built with the RSUSB backend method, as that type of librealsense build is not dependent on Linux versions or kernel versions and does not require patching

[doisyg]

A roadmap for a proper release to the current Ubuntu LTS (22.04) would be a minimum. I believe there are very few adaptation to make for the tooling executables to work (i.e realsense-viewer). The library itself works just fine by forcing the installation of the focal deb:

[MartyG-RealSense]

Thanks so much @doisyg for your confirmation that librealsense can be made to work with Ubuntu 22.04.

[dheera]

Intel do not provide schedules and roadmaps in advance for possible supported RealSense features in the future, however.

Why not? Can we please get real support instead of canned responses here? This is the LTS release of the most popular Linux distro in the world, and by far the most popular OS for robots, a little friendliness in communication with the dev community about timelines would go a long way. We do pay for these devices.

[doisyg]

It doesn't make sense to close this issue until realsense is properly released to Ubuntu 22.04. And this is the good place to communicate about the progress, schedule, beta and blocking points I believe.

[doisyg]

Well, if it is going to be released for Jammy, this issue should be left open until it is. There is no problem in leaving issues open for a long time, it is actually good practice, signaling to the community that it is being addressed, for instance: https://github.com/ros-planning/navigation2/issues/1391 Closing the issue, on the opposite, maintain the doubt that it will never be done. And if that's the case, I need to plan and organize (I have more than 300 D435 in production to maintain), and I guess it is the same for many other people using D400 cameras in production. The realsense support improved compared to the early days of R200s but its history is a subject of stress for many products relying on it (I am sure @SteveMacenski can relate) and your response (and the overall realsense communication) is not at all reassuring. To the point that when starting a new project, many people (including myself) are looking for alternatives.

[MartyG-RealSense]

For stable long-term support I would recommend using SDK and firmware pairings that Intel has categorized as Production (suitable for critical applications and commercial products). The most recent Production configuration at the time of writing this is SDK 2.50.0 and firmware 5.13.0.50.

[SteveMacenski]

To @doisyg ’s comment, that attitude is incredibly problematic and why most companies are looking to Realsense alternatives even though they dont want to. Hardware is great, software support is some of the worst I’ve ever run into… it should take a day to release for 22.04 but Intel really can’t spend a day on it?

[smorillon]

This problem is not solved but closed!? Can you reopen this issue so that people don't look for solutions in this thread when there are none?

[davetcoleman]

Hi, I represent a company very well established in the ROS 2 community (PickNik). We've worked with 70+ companies, including Intel, helping them best use ROS with their robots, and we frequently recommend and sell Realsense cameras into our client projects. However we are switching to Jammy and a lack of driver support is a pretty big deal for us.

I generally agree with @SteveMacenski's sentiment here.

[Nir-Az]

Ubuntu 22.04 librealsense Debians & ROS2 Humble RS camera node support are on the future roadmap. Stay tuned...

[pepisg]

Hi. I wrote to Intel Realsense's sales team to ask for a timeline on the release (the company I work for relies on realsense cameras for the main product as well). He told me the release was planned for December 31st, but that they would try their best to push it forward. Sadly it seems that it will still be a long time :(

[doisyg]

Ubuntu 22.04 librealsense Debians & ROS2 Humble RS camera node support are on the future roadmap. Stay tuned...

This is reassuring and then

He told me the release was planned for December 31st

this is alarming

There is almost nothing to do. As described above, it is already working on Humble/Jammy by forcing the install of the Focal packets (at least for the D435s). Just add Jammy to the deb repo. What's missing is maybe the kernel patch for the metadata, but for many of us it is not needed (and it was already the case for the lastest hwe kernel in Focal). And a recompilation of the realsense-viewer GUI. If the timeline is really 31st of December, I am going to end up doing it and creating an alternate deb repo.

I don't understand how complex stacks like Moveit 2 or nav2 are ready very soon after the Humble release, and something as trivial as this is taking months.

[mengyui]

There is a draft kernel patch in the PR https://github.com/IntelRealSense/librealsense/pull/10625 It should enable metadata on Ubuntu using kernel 5.13/5.15.

BTW, I have a pre-built package for testing in here.

[aagrawa3-dev]

Hi Realsense team, We strive to migrate to Ros2-humble (which is based on Ubuntu2204).

relasense SDK

As suggested, we tried compiling relasense SDK on U2204. https://github.com/IntelRealSense/librealsense.git It is compiled.

realsense_viewer:

Also works but we see this error(in red box) which does not go away even after applying udev rules from librelasense repo & rebooting machine. Please suggest solution for it:

ros2-wrapper:

The ros2-wrapper for realsense seems not working when compiled on ros2-humble. Its compiled but a small patch in makefile was needed. Is it expected and can this patch be released officially?

Do you know how to solve this issue?

[MartyG-RealSense]

Thanks very much @aagrawa3-dev for your makefile patch for the beta wrapper! I have passed the details to the ROS2 wrapper development team. Official support for Humble in the ros2_beta wrapper is being worked on.

The launch error that you reported was previously experienced by a RealSense ROS user at https://github.com/IntelRealSense/realsense-ros/issues/2245 and they suggested setting a dynamic_typing flag as a fix.

In regard to missing udev rules, please try installing them with the instructions below.

sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && udevadm trigger

Update: Building from source the RS camera ROS2 wrapper now support Humble distro (See PR: https://github.com/IntelRealSense/realsense-ros/pull/2406)

Kernel patched for 5.15 is not included, so the support is currently without full metadata.

Still on the roadmap:

• Jammy Debians
• Kernel patches for 5.15

Hi @Nir-Az Thanks for info. But this patch is merged to branch "IntelRealSense:ros2-beta" !!

Is this branch going to be main branch for humble upgrade? When is it planned to merge to development branch?

[Nir-Az]

Hi @aagrawa3-dev ,

I know it might be confusing but I will try to clarify the realsense-ros repo branches, We develop/maintain ROS1 + ROS2 on this repo, on different branches. If you notice on the development branch readme, it said that this is the ROS1 branch.

This version supports Kinetic, Melodic and Noetic distributions.

For running in ROS2 environment please switch to the [ros2 branch](https://github.com/IntelRealSense/realsense-ros/tree/ros2-beta).

The ROS2 branch is ros2-beta Meaning only ros2-beta branch can support ROS2-Humble as ROS1 latest support is Noetic distro.

Hope it helps..

Hi @AustinDeric ,

This error is raised when building with GCC >= 10 Thanks to @chris-durand a fix PR was merged into development branch yesterday (@MartyG-RealSense FYI). To get it, retry running the docker image but before adjust your docker file to use development branch

Change this:

RUN git clone https://github.com/IntelRealSense/librealsense

to this:

RUN git clone -b development https://github.com/IntelRealSense/librealsense

Good luck!

[MartyG-RealSense]

Thanks very much @Nir-Az for the FYI :)

There is one COPY realsense /invisible/src/realsense argument.

This folder contains a raw copy-paste of the github repository: git clone https://github.com/IntelRealSense/realsense-ros.git -b ros2-beta

and all the unpacked .deb files from https://github.com/mengyui/librealsense2-dkms/releases/tag/initial-support-for-kernel-5.15

I had to go this route with cloning the repo because there is a compile-time error. The github repo searches for:

find_package(realsense2 2.51.1)
if(NOT realsense2_FOUND)
    message(FATAL_ERROR "\n\n Intel RealSense SDK 2.0 is missing, please install it from https://github.com/IntelRealSense/librealsense/releases\n\n")
endif()

There is a versioning mismatch somewhere which I couldnt trace. But removing the release version requirement makes it build and run.

find_package(realsense2)
if(NOT realsense2_FOUND)
    message(FATAL_ERROR "\n\n Intel RealSense SDK 2.0 is missing, please install it from https://github.com/IntelRealSense/librealsense/releases\n\n")
endif()

cheers

Hi, is there any plan or work in progress that try to resolve the build error of arm64 build in ros humble? https://build.ros2.org/job/Hsrc_uJ__librealsense2__ubuntu_jammy__source/
