Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |DUPLICATE --- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- I've got no idea what this error is caused by because the relevant operator!= is clearly present on line 550 of <bits/fs_path.h>, but I'm surprised <filesystem> is even installed for MinGW. It should only be installed conditionally, like <experimental/filesystem>, but I forgot to do that. But this will get fixed soon, as part of PR 78870, so closing as a dup of that one. *** This bug has been marked as a duplicate of bug 78870 ***
