The trick doesn't say what is the root cause, I suspect a new comer (glibc is my favorite):
What program can detect an AMD or an INTEL processor?

- kernel: changed twice a week
- glibc: changed
- binutils: changed since the introduction of glibc
- llvm: hasn't changed since the introduction of glibc
- gcc : hasn't changed since the introduction of glibc
- qt5: changed

what else could cause that odd behavior?

qt5 builds without errors in SFS with glibc-2.33, all the cores are active.

That's the only package I've changed wrt slackware64 -current.

The problem lies in the presence of glibc-2.35 or the way it interacts with a package which causes the failure of qt5 building with the standard qt5.SlackBuild.

update: if I try build a 2nd time in SFS with glibc-2.33 I have the same message of error.

There's something else, less obvious than just glibc.

It begins to stink

I wonder if a complete mass rebuild with glibc-2.35 would help track than kind of problem?

attach.: patch from opensuse

PS: to avoid memory problem, since I have "only" 16G, and swap exceeds 30G during the build
I added 30G of zram swap,in addition to the initial swap (16G)

Code:

@marav: you don't keep the jumbo patch ?

Ahhh, I guess that explains my error messages and failed compile:

Code:

g++: fatal error: Killed signal terminated program cc1plus

And I guess 32gig RAM does not cut it....

how to do you add zram in swap?

No
As it compiled fine during my "nosmt" test without it
