As spotted by the community we also must take care of the libstdc++ used
And unfortunately Ubuntu ppa toolchain-r pull 3.4.28
-_-note: ubuntu-toolchain-r seems to pull libstdc++ 3.4.28 meaning the library built won't work on any fresh Ubuntu 18.04 LTS/Centos 9/Debian 10/
-_-note:
or inside a container
Trace: Ubuntu 18.04 gcc-11

So a good candidate could be a Centos-7 based docker image...

First test with 8.2.9025 (which has been built using a fresh Centos-7 seems ok)
Working example against an Ubuntu 16.04 LTS https://github.com/or-tools/java_or-tools/actions/runs/786806066
