rosserial and arduino

Question

Hi folks,

I have just upgraded to Ubuntu 20.04 LTS, and ROS Noetic. Following the instructions in the ROS tutorials, using ROS Noetic, everything worked fine except for the tutorial about installing Arduino IDE Setup: http://wiki.ros.org/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup I do the 2.1.1 (RECOMMENDED) Installing Binaries on the ROS workstation:

sudo apt-get install ros-noetic-rosserial-arduino
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package ros-noetic-rosserial-arduino

I suspect that the rosserial Arduino package is not yet provided for noetic. Am I right? Does anyone know when/if it will be? Or can I install this package in another way? I tried the build from source option too, but no success there... it simply does not work when I try to run the simple helloworld example in the next tutorial. Before I upgraded to Ubuntu 20.04, I ran 18.04 and melodic. It worked fine! Any help/advice much appreciated! All the best, Krister

You're correct. The index.ros.org page for rosserial_arduino says it is UNRELEASED.

Does anyone know when/if it will be?

When something will be released is a question only the maintainers would know. Good news is it looks like someone asked about a Noetic release here: https://github.com/ros-drivers/rosserial/issues/499

Or can I install this package in another way? I tried the build from source option too, but no success there... it simply does not work when I try to run the simple helloworld example in the next tutorial

Trying from source was the right thing to do. Since you discovered it doesn't work, the next step would be to open a pull request that fixes the issue, or if there is already a PR then I'm sure the maintainers would find it helpful if you tested it and commented if it works.

I think https://index.ros.org/p/rosserial_arduino/github-ros-drivers-rosserial/#noetic-overview says that it is released but still I am getting the same error. Any solution?

Answer 2

Hi, I was having the same problem. I upgraded to Ubuntu 20.04 and and the rosserial-arduino was not yet available for noetic. I was able to install using the 2.1.2, but using a specific branch in the git clone, which is gcc7-fixes, and it worked.

cd ws/src

git clone -b gcc7-fixes https://github.com/ros-drivers/rosserial.git

cd ~/ws

catkin_make

The catkin_make install was not necessary for me. My english is rusty, but I hope I've helped!
