ROS2 Foxy Install

[NathanDodson]

I'm trying to follow the steps in the read.md file at https://github.com/intel/ros2_intel_realsense/tree/refactor to install. I run sudo apt-get install ros-foxy-librealsense2, but the package does not exist. Anyone else get this issue?

What are you building on? IIRC apt only works on Intel Linux, not things like the Raspberry Pi. Here's the bit on the website:

Intel® RealSense™ SDK 2.0 provides installation packages for Intel X86/AMD64-based Debian distributions in dpkg format for Ubuntu 16/18 LTS. (on https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md)

That page also gives some instructions on how to add the repos.

Building from sources isn't too bad if you have to go that way.

I'm trying to build on my laptop. I'm not able to use the dpkg format since Foxy is only supported in Ubuntu 20 LTS. The link I provided refers to Foxy installs, but the command doesn't exist. I confirmed this with another person as well. @bobgates

Can confirm this is also an issue

[caelinsutch]

Even after building from source, it doesn't detect librealsense2 as installed :(. I installed it as documented here

Same issue here, any solution to this?

ROS: Foxy (installed via Debian Packages)

The Foxy release has been submitted to rosdistro, and now waiting for verification to get into the Foxy build. Thanks!

Confirmed that I was able to install by running sudo apt-get install ros-foxy-librealsense2 and successfully work through the instructions provided on the refactor branch.
`
This was done on:
Ubuntu: 20.04.1 LTS
Kernel: 5.4.0-42-generic
Device: D435 firmware version: 05.12.06.00
Note: The docs indicate kernel 5.4* and Ubuntu 20.04 arent officially supported as of some unspecified date in the past. I am not sure what is the up to date case now. Maybe @sharronliu can clarify.

I still run into run time issues though...will open a separate issue for this.

@surfertas I followed your approach but received the following error
any hint?

Verified that using the code and instructions under the refactor branch works in manually setting up the ros2_intel_realsense package in ROS2 Foxy successfully.

Instructions

The section below list the steps taken in setting up for use:

# Set up ROS2 workspace
cd $HOME
mkdir -p ~/realsense_ws/src && cd ~/realsense_ws/src

# Download refactor branch of ros2_intel_realsense
git clone https://github.com/intel/ros2_intel_realsense --branch refactor --depth 1

# Build package
cd ~/realsense_ws
source /opt/ros/foxy/setup.bash
colcon build

# Connect camera to workstation.

# Run package
source install/setup.bash
ros2 run realsense_node realsense_node
