At this time, this is not a problem. But, when trying to support H3 for Groonga (I maintain it in Debian), it might be troublesome. So I've filed this bug report in advance. In other point of view, doing similar way with other distributions is better to keep compatibility. e.g. in fedora, h3api.h is installed as /usr/include/h3/h3api.h https://fedora.pkgs.org/43/fedora-x86_64/h3-devel-4.3.0-2.fc43.x86_64.rpm.html When the difference of header location in debian is problematic, we need to apply vendor specific patch to them every third-party application. (even though currently not a problem yet) Wouldn't it be better to change it while there are still few apps that they're dependent on? (Of course, I think it's up to the maintainer to decide whether or not to implement the changes, considering the associated costs) Best Regards
