Hi,

Recent update to qtwebengine has failed to build on my system for some reason.

Regular build fails on dom_window:

While Jumbo has a different issue, usually i don't use it since it never worked for me but i wanted to compare both attempts.

Next time please post the log using Gentoo tool wgetpaste. If the log is too big for pastebin just cut a big chunk from the end. Most people do not want to download and unpack any logs. I did it only because I got curious and I had some free time. You are running parallel make, thus the error is way back in the log. Your compiler process is being killed, most likely you are running too many make instances concurrently and as a result you are running out of resources.

Code: Select all

PORTAGE_TMPDIR="/tmp"

Since /tmp over /var/tmp I "assume" that's tmpfs, combined with -j8 and only 16GB ram+noswap, there's good odds you ran out of ram/resources as post above pointed.

For ram there may be a note about it near the end of your `dmesg` output, and the build log likely has a line containing this:

Code: Select all

fatal error: Killed signal terminated program cc1plus

Alternatively perhaps your tmpfs ran out of space (long story short, in either cases don't build this on tmpfs).

If something else, need to see more complete logs, just guessing here.

Writing as someone who just today briefly exhausted a tmpfs while building something a bit too big for it, I can say that you won't get a SIGKILL over exhausting tmpfs (that is, trying to write 8G of files into a tmpfs mounted with size=7G). Instead, any attempt to write to the tmpfs fails with ENOSPC ("No space left on device"), which will in almost all cases be an unhandled error, and the build will terminate. Well behaved builds will write a message to stderr mentioning "No space left on device" as the failure reason. In my case, I had sufficient RAM+swap to accommodate the tmpfs being full and still keep all my programs alive, so the only negative was that I had to restart the build with more space.

However, to Ionen's point, if you don't have sufficient RAM+swap to support all your open programs, plus all the space used by the tmpfs, then you will get an Out Of Memory, and likely a SIGKILL. This would happen even if you had mounted the tmpfs with size= set to a value far greater than the package needs. In such a scenario, you haven't exhausted your tmpfs - but you have exhausted your virtual memory.

I did it only because I got curious and I had some free time. You are running parallel make, thus the error is way back in the log. Your compiler process is being killed, most likely you are running too many make instances concurrently and as a result you are running out of resources.

Sorry, you are right but it was just too big and i had cases where people needed the full log but i did add the end as part of my post here in the forums, was it not long enough?
I'm curious where did you see signs of the problem you described?

PORTAGE_TMPDIR="/tmp"
Since /tmp over /var/tmp I "assume" that's tmpfs, combined with -j8 and only 16GB ram+noswap, there's good odds you ran out of ram/resources as post above pointed.

For ram there may be a note about it near the end of your `dmesg` output, and the build log likely has a line containing this:
Code: Select all
fatal error: Killed signal terminated program cc1plus
Alternatively perhaps your tmpfs ran out of space (long story short, in either cases don't build this on tmpfs).

If something else, need to see more complete logs, just guessing here.

Thanks this is exactly right on both

Hu wrote:Writing as someone who just today briefly exhausted a tmpfs while building something a bit too big for it, I can say that you won't get a SIGKILL over exhausting tmpfs (that is, trying to write 8G of files into a tmpfs mounted with size=7G). Instead, any attempt to write to the tmpfs fails with ENOSPC ("No space left on device"), which will in almost all cases be an unhandled error, and the build will terminate. Well behaved builds will write a message to stderr mentioning "No space left on device" as the failure reason. In my case, I had sufficient RAM+swap to accommodate the tmpfs being full and still keep all my programs alive, so the only negative was that I had to restart the build with more space.

However, to Ionen's point, if you don't have sufficient RAM+swap to support all your open programs, plus all the space used by the tmpfs, then you will get an Out Of Memory, and likely a SIGKILL. This would happen even if you had mounted the tmpfs with size= set to a value far greater than the package needs. In such a scenario, you haven't exhausted your tmpfs - but you have exhausted your virtual memory.

Thanks for the additional info it really helps, when i created this system i made it RAM only at that time 16G was a lot and i didn't think anything will eat that much ram so no swap was needed (also hdd is slow and ssd didn't exist yet).
I was wrong and didn't take into account many thing including building packages on the system as heavy as qt and chrome and\or having programs like firefox eat up big portions of ram while attempting to build such heavy packages on the system.
So this is a recipe for running out of memory, strangely enough some version compile without a hitch while others failed like this, my guess is it depends on the programs running at the time of a build and the version being build, just luck of sorts.

Lessons learned, with this i just wanted to improve my debugging skills and understand what is the issue since the build wasn't being the most user friendly one.
Thanks everyone for the help.

Remember that you can also work the solution for a middle ground:

1- You can reduce the number of threads, per package:

/etc/portage/env/makeopts-j2.conf

Code: Select all

MAKEOPTS='-j2'

/etc/portage/package.env

Code: Select all

dev-qt/qtwebengine makeopts-j2.conf

This will reduce a lot the use of RAM memory in this package.

2- You can also use zram instead of tmpfs. I'm getting good results using zram with zstd. But remember to create a much larger partition (it may even be larger than the RAM total size, because of the compression).
In one of my builds, portage was using around 4GB of space, but with zstd compression, zram was actually only using around 1.5GB of RAM for the files. The compression rate for build artifacts is quite good.

Interesting

How do i know how many threads do i need?
Similarly with zram how much is enough?

Well, this is just a suggestion, as it varies from package to package, but for dev-qt/qtwebengine, you can think of 2GB of RAM per thread. And do the calculations based on your use, as it's good to be able to use the machine while installing in the background.

Troopo wrote:Similarly with zram how much is enough?

Well, as for zram, it will only allocate what it's using (and unlike tmpfs, it actually tells the system how much it's using, making it easier to monitor). Since you have 16GB of ram, you can easily create 16GB partitions, which will not be an issue (this 16GB, will use something around 6GB of the real RAM with zstd, and only if it's full). You can monitor with the zramctl command.

I recommend reading these 2 guides:
