--- Comment #9 from Boudewijn Rempt <b...@valdyas.org> ---
This turns out to be an issue with the CPU of the machine we build on:
19:39:42 < bcooksley> I wonder
19:39:48 < bcooksley> the new builders are Ryzen 7 boxes
19:39:55 <@boud> oh...
19:39:57 < bcooksley> they'll have all the latest CPU features
19:40:11 < bcooksley> Vc wouldn't be trying to use instructions that aren't
valid on older machines would it?
19:40:30 <@boud> I don't know, but this makes me suspcious!
19:40:31 < bcooksley> 3rd gen Ryzen 7s even, the absolute latest you can get
19:40:39 * tiar does pat-pat
19:40:59 <@boud> tiar: je vous en remercie, beaucoup
19:41:32 < bcooksley> it's very nice having Octa Core processors for our
builders i'll say that much :)
19:41:45 < bcooksley> (and double the storage too, so hopefully no more disk
space issues for a long time)

19:42:07 < bcooksley> is the relevant section from /proc/cpuinfo
19:42:16 <@boud> bcooksley: maybe I should get one of those devices, if not for
me, then for vir or dmitryK|log...
19:42:38 < bcooksley> compared with the older machines...

19:42:59 <@boud> oh gosh
19:42:59 <@boud> oh gosh
19:43:02 <@boud> yes...
19:43:18 < bcooksley> I see sse4* stuff
19:43:22 <@boud> We had bug reports before from arch users with ryzen machines
who had crashes
19:43:54 < bcooksley> probably the same cause, just in reverse now...
19:44:10 < bcooksley> the Appimages and Windows builds probably work perfectly
for them now :D
19:45:32 <@boud> well...
19:45:57 < bcooksley> got a demo .kra I can test trying to save a jpeg with?
19:46:03 <@boud> I guess I need to ping Vir, and after that, tell our community
that releases are not going to be forthcoming
19:46:15 < bcooksley> (to see if it works on a Ryzen machine)
19:46:22 <@boud> bcooksley: it's easy enough; start the latest nightly build,
create an image, save it as jpeg, crash.
19:46:32 < bcooksley> even a blank image?
19:46:34 <@boud> no need to even draw anything
19:47:49 < bcooksley> push comes to shove on Vc, I can always provision the
remaining Intel machine into the Binary Factory
19:48:03 < bcooksley> that will only work as long as you don't need Webkit or
Webengine though
19:48:09 < bcooksley> as it only has 8GB of RAM
19:48:14 <@boud> that would help, I'm sure, but we still need to get to the
bottom of this problem
19:48:27 <@boud> though, webkit/webengine, nah, not going to ship that!
19:48:34 < bcooksley> and 8GB isn't enough to build either of those two pesky
things
19:48:55 < bcooksley> I have to throw 24GB RAM at the problem
19:49:03 < bcooksley> to make webengine build on Windows in debug mode
19:50:08 -!- Bollebib [~instan...@178-118-189-121.access.telenet.be] has joined
#krita
19:51:41 < tiar> bcooksley: no problem, Krita doesn't build on Windows in Debug
mode anyway :D

19:51:52 < tiar> ...maybe that's the reason it doesn't build though...
19:52:23 < bcooksley> boud: drawing a line and saving a jpeg both completed
perfectly on the builder itself
19:52:42 < bcooksley> congrats, it's a supported CPU instruction issue :)
19:53:03 < bcooksley> probably just a case of telling Vc, ignore SSE4 support
being available, don't use it
19:53:52 < bcooksley> hopefully that isn't too hard to do
19:54:06 < bcooksley> is there a way to easily test the Python support?
19:54:40 <@boud> bcooksley: oh, thanks! I can try to figure out a way around
that, or rather, tell dmitryK|log to figure it out :-)
19:55:05 < bcooksley> hopefully Vc has some defines you can pass to it
19:55:13 < bcooksley> the above flags should hopefully help with that diagnosis
19:56:16 < bcooksley> I can provide the flags for an older 6th Gen Intel i7
machine if that helps in scoping out compatibility
19:56:35 < bcooksley> i've no access to anything aside from Ryzen 3rd Gen alas,
but someone in your community likely does :)
19:56:37 <@boud> yes, please, and Ill make a note and delegate :-)
