Required information:

  Ubuntu 20.04 LTS
• OpenRMF installation type:
  I've followed the installation instructions available at: https://github.com/open-rmf/rmf
• OpenRMF version or commit hash
  I double-checked that every package was in its main branch, and I fetched and pulled every single one.

Description of the bug

I'm having some issues while compiling the RMF framework. I've downloaded the whole thing using the instructions provided here: https://github.com/open-rmf/rmf. When I execute the command colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release, I get the following errors:

and

Before compiling, I double-checked all the packages with git pull, to ensure that I had the latest version of each one. Besides, I also have deleted the "build", "install" and "log" folders after the error, and then I tried compiling again. Same error. Lastly, I deleted the whole thing and tried once again, carefully following the installation instructions (github.com/open-rmf/rmf). Same outcome, that error related to the "rmf_traffic_ros2" package.

Besides, I also spend a few hours searching for a similar issue, and I found this one: open-rmf/rmf_ros2#157. I've tried what they mentioned (even though it's not the same issue), but it didn't fix my error.

I'm not sure, but it seems to me that this "rmf_traffic_ros2" package does not exist anymore, but there are still some references to it. That's is my guess.

Any help is appreciated.

It seems that rmf_traffic_ros2 is linking to an old version of rmf_traffic, Could you try removing existing debian installation and build and install and rebuild again?

sudo apt purge ros-galactic-rmf-*
