Thanks for letting us know. Glad tango is running on freebsd as well. I don’t have a freebsd VM here available, so I would be interested if the tests (catch2 only) pass? Something like cmake –workflow ci-debug-linux should compile and run them. Some can be flaky, so sometimes you need to rerun with ctest --build-and-test . build/debug --build-generator Ninja --build-noclean --test-command ctest --output-on-failure --rerun-failed.
