@mgrallos Is your problem solved? @TheSeanParker I followed the steps in the readme，I also encountered the same problem. The environment I use is ubuntu20.04 installed in the vmware16.0pro.My problem is:

I have already solved this problem, I use the zip file given to me by others, and then decompress it, and the problem does not appear after following the readme operation.

I solved the problem by replacing the version of Pangolin. The initial version I had was 0.8, and I replaced it with version 0.6, which didn't have this issue.

[iphylq]

you should update your pybind11 to v2.11 or before, i just use v2.11 to work good.

Yea, it is removing error when i try to colcon build --symlink-install --packages-select pangolin

Had the same compilation error while building version 0.9.1 of Pangolin (SDV-LOAM dependency) on Ubuntu 20.04. Made it work by using Pangolin 0.6.

[christian-rauch]

Is this still an issue on the current master (i.e. with #906)? The CI builds the pango_python component without an issue: https://github.com/stevenlovegrove/Pangolin/actions/runs/7820164725/job/21334232895.
