At a first glance, this could be a problem in fmt 9.0.0 that was indeed updated in Homebrew 5 days ago, see Homebrew/homebrew-core#105132 . I checked why this was not happening on conda-forge, as in theory fmt was updated also there: conda-forge/fmt-feedstock#30 . Apparently the spdlog of conda-forge is still using an old vendored version of fmt, see https://github.com/conda-forge/spdlog-feedstock/blob/4e0b46c6f245efc44a930d6a0de3858bfb2926cc/recipe/meta.yaml#L19 . This is probably an issue on the conda-forge side. However, fmt 9.0.0 eventually will arrive also on other distros, so perhaps we may need to look into that?

Indeed, the same error can be found in blf CI: https://github.com/ami-iit/bipedal-locomotion-framework/runs/7935832360?check_suite_focus=true .

Regarding that, I opened an issue in conda-forge/spdlog-feedstock#49 .

[GiulioRomualdi]

Fixed in ami-iit/bipedal-locomotion-framework#556 I think we can reenable brew CI

Also latest releases are tested, so better wait for the next blf release.

[traversaro]

blf 0.10.0 was released at the end of september, we can renable ci on homebrew.
