Description Agostino Sarubbo gentoo-dev 2023-12-27 08:44:59 UTC

Issue: dev-qt/qtwebengine-6.6.1 adds -Werror flag on its own (GCC-14-SYSTEM).
Discovered on: amd64 (internal ref: gcc14_tinderbox)

(GCC-14-SYSTEM) in the summary means that the bug was found on a machine that runs gcc-14 but this bug MAY or MAY NOT BE related to the new compiler
-Werror is not recommended for releases and should always be disabled when encountered in build-logs, because there are numerous cases where this breaks without purpose.

Created attachment 880367 [details]

build log and emerge --info (compressed because it exceeds attachment limit, use 'xzless' to read it)
Comment 2 Ionen Wolkens gentoo-dev 2023-12-27 09:00:33 UTC
That's only the Gn bootstrap rather than qtwebengine itself, mostly likely from:

    if not options.allow_warnings:

Won't bother with this now but I'll have a look next time I update the patchset (it's nice that it's an option, but there's currently no way to pass options to without patching).

    dev-qt/qtwebengine: update patchset for 6.6 and 6.7 branches
    6.6-8 -> 6.6-9 and
    6.7-3 -> 6.7-4 changes:
      * gn-bootstrap.patch (updated to not pass -Werror wrt bug #920758)
      * samurai.patch (unnecessary with the new app-alternatives/ninja)
    Meant to do these last time updated patchsets, but forgot to read
    my notes when worked on that. Doing it now so that it will be in
    the 6.6.2 release in ~2 days.
