@andrew.46: what are the specs of your machine?

I have an AMD Threadripper 2950X. A fascinating issue you have discovered!

Definitely !

I'm curious how a build process that is supposed to understand only the architecture (x86_64) knows that we have an AMD processor.

pfiou ... that was so long ... (more or less 3h)

It finally builds fine, disabling SMT in the kernel command line

That's probably not the solution
But, at least, a good starting point

If andrew can confirm
he is without a doubt the fastest of us

You have lost me there: 'disabling SMT in the kernel command line'?

Upgrading to that version of qt5, solved also the build of libksieve in kdepim, and all kde non building packages.

Thanks to all AMD testers.

hi Andrew,

You can disable the Multithreading in 2 ways :
- the one nobodino uses : echo off > /sys/devices/system/cpu/smt/control
- directly in the bootloader options : nosmt
it can be GRUB_CMDLINE_LINUX="nosmt" (grub) or append="nosmt" (lilo)

@nobodino
Wouldn't it be interesting to see if it works without the jumbo patch ?

EDIT: forget it, it works without the jumbo patch, because my last try was without it

nobodino · 03-10-2022, 01:47 AM

I've to go to work now.

marav · 03-10-2022, 01:57 AM

@nobodino

I think this:

Code:

+if [[ "$CPU"=="AuthenticAMD" ]]; then
+	echo XX > /sys/devices/system/cpu/smt/control
+elif [[ ! "$CPU"=="AuthenticAMD" ]]; then
+	echo
+fi

is useless

Ok, disabling SMT,build qt6-webengine:

Slackware package /tmp/qt6-webengine-6.2.3-x86_64-1gm.txz created

but, start at 8h49 end to 16h29, whith my AMD FX 6300 six core, 8 Gio of memory.

Perhaps a good idea, yes

@gmgf : could you share what's needed to build qt6-webengine ?
