Description Adam Williamson (Red Hat non-Fedora) 2026-04-18 06:50:47 UTC

For some reason, qt6-qtwebengine does not use the %qt6_qtwebengine_arches macro, which exists precisely to define the arches qt6-qtwebengine builds on. This is a problem because at least one other package, kaidan, expects it to do this job:

https://src.fedoraproject.org/rpms/kaidan/blob/136fdf0f27ccc5c420600959049a417e549fb68a/f/kaidan.spec#_14

so through no fault of its own, kaidan builds on s390x but is uninstallable:

Pre-existing dependency problems in the tested packages themselves:
package: kaidan-0.15.0-2.eln156.s390x from file:///mnt/update_repo
  qt6-qtwebengine(s390-64)

There is a FIXME in the spec for this that's been there since 2023. Can we please just...fix it?

# FIXME use/update qt6_qtwebengine_arches
# 32-bit arches not supported (https://bugreports.qt.io/browse/QTBUG-102143)
ExclusiveArch: aarch64 x86_64 ppc64le

Comment 1 Jan Grulich 2026-04-20 10:07:57 UTC

Hi, I'm not sure I understand what is the issue. Changing qtwebengine to use the macro will have same result as the macro is defined as:
> %qt6_qtwebengine_arches x86_64 aarch64 ppc64le riscv64

Comment 2 Adam Williamson (Red Hat non-Fedora) 2026-04-20 15:49:01 UTC

Per the bug above, at least on ELN, %qt6_qtwebengine_arches apparently includes s390x, or else kaidan would not build on it.

Comment 3 Jan Grulich 2026-04-20 17:36:12 UTC

The issue is in Kaidan:

>%if 0%{?fedora} || 0%{?epel} > 7
># handled by qt6-srpm-macros, which defines %%qt6_qtwebengine_arches
># Package doesn't build on arches that qtwebengine is not built on.
>ExclusiveArch: %{qt6_qtwebengine_arches}
>%endif

This is skipped on ELN so it automatically builds on all arches.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
