[SOLVED] qtwebengine fails to build

[Troopo]

Hi,

It seems qtwebengine exists only to annoy me as this is the 1000000 time i have an issue building it.

I've tried with and without jumbo-build, i've cleanup up some space and i've added a 10GB swap, no further ideas, please help.

[fedeliallalinea]

Usually Segmentation fault error is related to an hardware issue.

[Jaglover]

I concur with fedeliallalinea, for me segfault does not associate with OOM killer. I think it is possible to get segfaults when your toolchain is broken (like damaged binaries due to filesystem corruption or hard drive failure), in addition to hardware failures. In this case I'd suggest reducing make instances and see if this segfault can be replicated in exact same point of compilation.

Thanks but didn't see anything there, here is the log

Usually Segmentation fault error is related to an hardware issue.

True, I've experienced as much in the past with hdd failures but there were signs of that coming, this time i don't see any problems, this is purely update related.

I got the same message with jumbo-build as well, log just in case

Maybe this is also related?

No this report a possible problem in world file but isn't related to your compilation problem.

Ok, sounds like a good approach for debugging, how do i reduce the instances?

[Tony0945]

Even though it isn't related, I would quickpkg qtwebengine (another monster to compile)a nd then --depclean it to get it out of @world because it didn't belong there in the first place. this will take very little time and make your system cleaner.
Icu, thoug, is a direct dependency. Definitly fix icu. If you run the command I gave it will tell you why icu is not building, probably and old mask you've forgotten about.

I somehow feel this might be python related with the 3.8-3.9 migration.
Is this normal? should it use 2.7?

Yes python2.7 is present in the tree for these situations when it's required as build dependency.

Even though it isn't related, I would quickpkg qtwebengine (another monster to compile)a nd then --depclean it to get it out of @world because it didn't belong there in the first place. this will take very little time and make your system cleaner.

I can't really do a --depclean since i need to finish the update and it's stuck at qtwebengine (bane of my existence) but i did check the dependencies for qtwekit and it had none so i unmerged it, as for icu, i have 69 as i wrote earlier no idea why it would use 68, i have no masks that i've applied.

By reducing make instances a had in mind MAKEOPTS set to something less than -j8.

Got it, will report back after i try

I'm VERY sorry for the mistake. I meant qtwebkit not qtwebengine, which, of course, you are trying to build.

the principle being invoked is "When you don't know what's wrong, but you know something that you think is unrelated is wrong, fix that first. Very often it will fix the problem that you thought was unrelated." Taught to me decades ago by an old mechanic. He was right. He was talking about mechanical systems, but it applies even better to software.

No worries, we all make mistakes, point is, i got what you meant and handled that.
But i really think that icu version you caught was the actual fix, after rebuilding i'm now 90% done with qtwebengine which is further than it was before so i think this time it will run til completion.

The makeopts was the next thing i would try, i also found an older thread mentioning this, would have been strange since it's was working fine before on -j8 and not it wasn't? i guess that could happen somehow.

Regarding the analogy you provided, i agree, i came to a similar conclusion from some other things that happened to me in life but it's something i can relate to and i try to do on a regular basis whenever possible. so i think it's a great advice

It took longer but still failed with the same error.

I guess i will try the make instances now.

According to

Code: Select all

ebuild   R    ] dev-libs/icu-69.1:0/69.1::gentoo  USE="-debug -doc -examples -static-libs" ABI_X86="(64) -32 (-x32)" 0 KiB

dev-libs/icu-69.1 had already been installed on your system, nothing to see there.

It was already established that your type of error was not software related.

Why would i have a hw problem out of the bloom when everything seems to be working and the only thing that has changed is sw updates?
Anything i can do to verify that further?

So far we've got 3 build logs - and they clearly show that the errors occur at different points of compilation:

I'd try and cap the frequency of CPU 10-15% lower than its max. This will reduce the stress on hardware.
Example for Intel to set max to 4 GHz:

Code: Select all

cpupower frequency-set -u 4G

[Tony0945]

MAKEOPTS="-j8"

Is it an 8 cor3e CPU?

Many use twice the number of CPUS.
If it fails agin try this:
1. set Makeopts=-j to the value of "nproc". i.e. the number of cores. This will releive stress on the system.

2. Just try setting gcc to 9.3.0, just for laughs.

I will try that after the make changes and report back.

it's an i7-2600k so it's a 4 core cpu but yeah i went double based on the handbook or something like that, right now i have it running with 6 instead of 8 and then i will try 4 as you suggested lets see, but in my 6-7 years of gentoo that was never a problem with 8...

Will try gcc too, i somehow suspected my attempt at wayland a while back so i took down the wayland flag lets see if that helped too.

Will update in a while since every run takes a few hours.

Thanks so far
