Most Qt 5.15.3 tools (uic, lupdate, lrelease, …): Illegal instruction

[till213]

Most Qt command line tools (also GUI tools like designer, but I can‘t use those anyway due to a missing Xserver, I guess…) like uic, lupdate and lrelease immediately result in an „Illegal instruction“ and terminate right after invocation (also with „zero input“).

Examples:

 Olis-Airbag:/home/tknoll/resources/work/Qt/SkyDolly# /usr/lib/qt5/bin/qdoc
Illegal instruction
Olis-Airbag:/home/tknoll/resources/work/Qt/SkyDolly# /usr/lib/qt5/bin/uic
Illegal instruction
Olis-Airbag:/home/tknoll/resources/work/Qt/SkyDolly# /usr/lib/qt5/bin/lrelease
Illegal instruction
Olis-Airbag:/home/tknoll/resources/work/Qt/SkyDolly# /usr/lib/qt5/bin/designer
Illegal instruction

Other tools like qmake seem to work though:

Olis-Airbag:/home/tknoll/resources/work/Qt/SkyDolly# /usr/lib/qt5/bin/qmake -v
QMake version 3.1
Using Qt version 5.15.3 in /usr/lib

This is on a fresh iSH installation from yesterday (wiped and re-installed from the App Store):

• iPadOS 15.3.1 (latest at the time of this writing)
• IPad Air, 3rd generation (64 GB)

Olis-Airbag:/home/tknoll/resources/work/Qt/SkyDolly# uname -a
Linux Olis-Airbag 4.20.69-ish iSH 1.2.3 (298) Dec 17 2021 06:08:24 i686 Linux

The Qt 5.15.3 development tools had been installed with:

apk add qt5-qtbase-dev

(Plus other tools like cmake, g++, make, git)

I have not changed any package repositories (I currently wouldn‘t even know where/how), so I believe most everything else is „plain vanilla iSH“.

Here is what I believe is the relevant dmesg output, for the failed command „uic“:

Olis-Airbag:/home/tknoll/resources/work/Qt/SkyDolly# /usr/lib/qt5/bin/uic
Illegal instruction

dmesg output:

Just for the record (and completeness sake): the issue also occurs with the just released iPadOS 15.4 (not that I had expected any impact on this issue).
