As per the previous avx issues, they have a patch which is in the git version, it is this: https://codereview.qt-project.org/gitweb?p=qt/qtbase.git;a=blobdiff;f=src/corelib/global/qsimd_p.h;h=2136b390d64a6ac082bae72f11b0031fbe08b0b5;hp=55adcef6598feca6b11da3c3b039570b275a1919;hb=39d3af0c29147ff319e89c0be602d99af0af0996;hpb=6da6a17de9ccfcd5458ea72507b131660e0ab948 Reproducible: Always Steps to Reproduce: 1.Compile qtbase-6.6.0 on an older machine maybe? 2. 3. Actual Results: Fail to build Expected Results: build fx-8350 cpu, others with similar hw get this issue. See https://bugreports.qt.io/browse/QTBUG-114719
I applied that patch by hand and it build's here.
Huh, that's odd. This patch is included in 6.5.3 but seem missed the 6.6.0 release? eclass has workarounds to handle this for <6.5.3 but it is skipping the fma bit for >=6.5.3 given it expected it to be fixed. build.log would be nice to be able to confirm but guess I'll just extend the eclass workaround for now (would rather not modify system headers if possible).
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=5dbe5492e36a97ee169ed1490d8281691f9cc7dd commit 5dbe5492e36a97ee169ed1490d8281691f9cc7dd Author: Ionen Wolkens <ionen@gentoo.org> AuthorDate: 2023-10-13 16:32:28 +0000 Commit: Ionen Wolkens <ionen@gentoo.org> CommitDate: 2023-10-13 16:34:23 +0000 qt6-build.eclass: extend avx2/fma mismatch workaround to 6.6.0 6.6.0 is lacking qsimd_p.h changes that 6.5.3 had, will be in 6.6.1.
