It's not done with a simple rebuild, ptyhon-shapely

has an issue:

https://github.com/Toblerity/Shapely/pull/762

 

I'll open and link a bug report on https://bugs.archlinux32.org (as soon the server is

back, ahem).

 

Ok, fixed, try with python-shapely-1.6.4.post2-2.1.

 

Make sure you set Architecture=pentium4 in /etc/pacman.conf and do a full migration to the pentium4 branch of

Archlinux32, otherwise you might get a:

 

"This program requires an X86 processor that supports SSE2 extension, at least a Pentium 4 or newer"

 

somewhere in Qt.

Hello world! 

Having some launch problems for Cura on Archlinux32 5.3.1-arch1-1.0-ARCH, it's possibly Python related, has anybody seen anything similar:
 

$ cura

Running Python 3.7.4, and glibc 2.29-4.43, make and cmake is also installed along with all other listed requirements from https://www.archlinux.org/packages/community/any/cura/. libc.so, libc.so.6 is located under /usr/lib/, I have also added this location to the $PATH variable. Is Cura calling the libc from some other location? 

Don't feel like posting this as a bug just yet, seeing that it's an older version of Cura, but has anyone encountered this? 
 

Yeah, actually python-shapely is doing that, actually that package has not been rebuilt for ages on Archlinux32. I'll try to rebuild it.. we had some issues with the dependency database lately, so that might be the root cause.

 

It's not done with a simple rebuild, ptyhon-shapely

has an issue:

I'll open and link a bug report on https://bugs.archlinux32.org (as soon the server is

back, ahem).

I can't really help with Archlinux32 as I don't use it but I just want to say that the current Cura compiles and runs quite happily on the Pi4 which is 32 bit armhf architecture. So there's no problem using Cura on a 32 bit system per se.

Yes, if it doesn't run, it's absolutely our responsability to make it work on Archlinux32. I expect some rebuilding issue around python to be the problem..

[Archlinux32 + Cura 3.4.1]

Hi, a Archlinux32 maintainer here, I can confirm the problem

with cura 4.2.1-1.0. Cura seems to have trouble loading the C library in the python-shapely module.

 

Feel free to report in https://bugs.archlinux32.org or

the forum https://bbs.archlinux32.org.
