Description Dimitry Andric freebsd_committer freebsd_triage 2026-02-10 19:55:46 UTC 
With libc++ 21 www/qt5-webengine fails to build, with errors similar to:

    In file included from gen/third_party/blink/renderer/platform/platform_jumbo_54.cc:7:
    ./../../../../kde-qtwebengine-5.15.19p0/src/3rdparty/chromium/third_party/blink/renderer/platform/image-encoders/image_encoder_utils.cc:63:5: error: static assertion expression is not an integral constant expression
    [...]
    ../../../../kde-qtwebengine-5.15.19p0/src/3rdparty/chromium/base/metrics/histogram_macros_internal.h:45:12: note: integer value 8 is outside the valid range of values [0, 7] for the enumeration type 'RequestedImageMimeType'
       45 |     return static_cast<Enum>(
          |            ^

https://chromium.googlesource.com/chromium/src/+/bb340f66aaf44206fa5106509fb4e8c0719ee831
fixes these, but has to be slightly adjusted to make it apply to the
specific chromium version included in qt5-webengine.

This also needs the change in https://github.com/DimitryAndric/freebsd-src/commit/7a8a78577d6cb7d82bdc38ffd7515618f44af9de, since I ran into a clang bug affecting older chromium forks: https://github.com/llvm/llvm-project/issues/179118
