PyQt6 errors on processor without ssse3 sse4.1 sse4.2

[TimRegeant]

Is this a new report?

Yes

System Info

Void 6.12.91_1 x86_64 AuthenticAMD notuptodate hold rrrrmDDDDFF

Package(s) Affected

python3-pyqt6-6.10.2_1

Does a report exist for this bug with the project's home (upstream) and/or another distro?

No response

Expected behaviour

Running a python3 script with "from PyQt6.QtWidgets import QApplication" dependency and PyQt6 installed should allow successful execution.

Actual behaviour

Program launch fails with:

Incompatible processor. This Qt build requires the following features: ssse3 sse4.1 sse4.2

Steps to reproduce

Run python3 script with dependancy on PyQt6 using AMD processor.
Program launch will fail.

which model of cpu?

[TimRegeant]

AMD Phenom II X6 1100T

Basically it is telling you your processor is too old and does not have the features to run. Your processor does not have support for those ssse variants and there for not compatible. I checked and its true your processor does not support those instruction sets.

[TimRegeant]

Yes, I understand that. My issue is why the package maintainer for void is compiling with cpu flags that disallow users from being able to run Qt6 programs. The cpu I have is perfectly fine and there is no reason to not be able to use the Qt6 package in the repository other than the flags used to compile it.

[devilsclaw]

This is verging on discussion but are you saying the everyone else should have slower program so that a 18 year old processor can run a program on a OS that is rated to be bleeding edge and for advanced users. Why not modify the template and compile it with the flags you want.

[classabbyamp]

@devilsclaw please don't speak for us. we do document that for x86_64 one should expect things to work if the processor supports SSE2, thus this is a bug.

as a side note, we do not rate Void to be "bleeding edge", not sure where you got that idea.

I can't reproduce this in qemu using the kvm64-v1 CPU (which does not support ssse3 sse4.1 sse4.2) and a basic PyQt6 application:

@TimRegeant can you provide more precise steps to reproduce this? Was this in a python virtualenv? What application caused the error?
