The following should address the issue, although the question stands: are we doing something wrong or this is a flex bug. https://patchwork.freedesktop.org/series/14477/ Is this a blocker for 13? The release won't need flex to compile as it'll be pre-generated for the tarball (In reply to Mike Lothian from comment #2) > Is this a blocker for 13? The release won't need flex to compile as it'll be > pre-generated for the tarball That's correct. Some distros still do autoreconf + friends which leads (not 100% sure) to those being re-generated. Fwiw this and others are more of "personal favourites". If they're not ready for 13.0.0, there's always 13.0.1 ;-) Looks like a flex bug: https://github.com/westes/flex/issues/113 |
