Hi!

I'm new in the Gentoo's world and after a fresh install, I emerge xorg and then chromium... but with all the dependencies chromium take about 2 hours to compile. It is normal, or I misconfigured something?

I have a Pentium B970@2.30Ghz with 6GB of ram on x86_64 gentoo.


thanks.

My old Core2 Duo with 4GB of RAM used to take 3 hours just for Chromium (ignoring dependencies).

My current Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz does it in 30 minutes (I have 16GB RAM, 16GB SWAP):

Code:

$ genlop -t chromium
 * www-client/chromium

     Wed Jan  8 15:39:19 2014 >>> www-client/chromium-31.0.1650.63
       merge time: 28 minutes and 36 seconds.

     Wed Jan  8 21:55:39 2014 >>> www-client/chromium-31.0.1650.63
       merge time: 28 minutes and 28 seconds.

     Thu Jan 16 16:59:32 2014 >>> www-client/chromium-32.0.1700.77
       merge time: 30 minutes and 43 seconds.


Two hours for all the dependencies plus Chromium is certainly reasonable.

Code:

$ genlop -t chromium

 * www-client/chromium

     Mon Jan 20 14:24:47 2014 >>> www-client/chromium-32.0.1700.77
       merge time: 1 hour, 52 minutes and 8 seconds.


so it look like just chromium take 1 hour 52 minutes , so if your old core2 take 3hours and your i7 take only 30 minutes, 2 hours is not bad.

thanks. [/code]

3 years later - a newer chromium version and newer system:
Code:
# genlop -tn chromium
 * www-client/chromium

     Fri Jun 16 12:16:59 2017 >>> www-client/chromium-59.0.3071.86
       merge time: 4 hours, 45 minutes and 34 seconds.


Is it the usual time or is something wrong with my system? I have compiled in RAM, with "AMD A8-7600 Radeon R7, 10 Compute Cores 4C+6G" and 16 G RAM. Swap was enabled but not used.
in make.conf the next setting was set:

Code:
PORTAGE_NICENESS=20
PORTAGE_IONICE_COMMAND="ionice -c 3 -p \${PID}"



Code:

there is no 20 in nice. the nicest is 19.
ionice -c3 takes longer to wait till idle.

4 hours is entirely normal, it took 3-5 for me with distcc over 6 cores.

You might want to enable ccache for chromium in package.env, it often saves a few hours during upgrades:
Code:
 ~ # echo www-client/chromium ccache.conf > /etc/portage/package.env/chromium.conf
 ~ # echo FEATURES="ccache" > /etc/portage/env/ccache.conf

thanks for this tip. haven't seen this documented anywhere. i'm stealing this for firefox libreoffice etc.

do you need to install dev-util/ccache?

webkit is what kills.
For those who don't have chromium installed, those who have epiphany (gnome3) or Evolution will pull in webkit-gtk which also takes a while to build.

Honestly firefox is not so bad to build if you have the RAM to link. It takes half as long to build firefox than to build webkit-gtk by itself on my systems...

On one of my systems: firefox takes a bit over an hour to build. Webkit-gtk takes about two and a half hours. I would suspect Chromium to take the full four hours or so...

Firefox 54 now has a hard dep on rust, which has effectively tripled its compile time.

Edit: and to add insult to XUL, rust makes both distcc and ccache useless. 5.5 hours and still compiling on my laptop...

That is a pity... Oh gosh more crap that uses llvm.

Supposedly llvm should be a synonym for gcc, but for whatever reason everything that requires llvm builds like crap.

I use firefox since before it was icecat, it was the best browser for a lot of time. Bit since the last updates in ~1 year it is really slow in runtime on my system. But the compile time was ok by 1:30 hour.
So I decided to give the chromium a chance, but the compilation time of factor 3x iritated me. The runtime is really fast comparing to the last firefox times I conditioned in the meantime.

Thanks for confirmation it is the correct compling time for chromium and not my system is broken or something like.

Oh, didnt even realize this, but yes it pulls rust even with -rust USE flag on...?

And rust takes 2,5x time of Firefox indeed.

There is no rust USE flag in Firefox 54+.

Well I was all ready to jump ship back to chromium today, but it turns out it has a hard dep on nodejs now, which has a hard dep on openssl. I'm using libressl so that kind of kills that plan.

Well something is really weird on my system, it seems.
I omit chromium from time to time since the compilation is really slow.
Now i checked the emerge.log and was shocked:

1497652431: >>> emerge (22 of 23) www-client/chromium-60.0.3112.24 to /
which is 17.06.2017 00:33:51

1497709553: === Unmerging... (www-client/chromium-59.0.3071.83)
which is 17.06.2017 16:25:53

nearly 16 hours, ok i got an AMD FX(tm)-4100 Quad-Core Processor (3600mhz) this is not high over the top.
But 16 hours are pretty long even for this old cpu.

I'll try the ccache setting.

Yeah, that seems really wrong. I did get chromium to build eventually yesterday (turns out there's an outdated nodejs in the libressl overlay which works), took nowhere near that long though:
Code:
 ~ $ qlop -gHd '1 day ago' chromium; lscpu | sed -n '12,16p'
chromium: Sat Jun 17 22:38:45 2017: 6 hours, 26 minutes, 31 seconds
chromium: 1 times
Model name:          AMD Phenom(tm) II X4 20 Processor
Stepping:            2
CPU MHz:             800.000
CPU max MHz:         2800.0000
CPU min MHz:         800.0000

Maybe this is an use-flag issue?

ebuild U ] www-client/chromium-60.0.3112.32::gentoo [60.0.3112.24::gentoo] USE="cups gnome-keyring gtk3 hangouts (pic) proprietary-codecs pulseaudio suid system-ffmpeg -component-build -custom-cflags -kerberos (-neon) (-selinux) (-system-libvpx) (-tcmalloc) {-test} -widevine" L10N="am ar bg bn ca cs da de el en-GB es es-419 et fa fi fil fr gu he hi hr hu id it ja kn ko lt lv ml mr ms nb nl pl pt-BR pt-PT ro ru sk sl sr sv sw ta te th tr uk vi zh-CN zh-TW"

No the new version compiles. I removed a forgotten --load-avg=3.2 from the cflags (this was left over) and did that ccache configuration.
I check it tomorrow.

Hu this is the result:

     Mon Jun 19 12:08:49 2017 >>> www-client/chromium-59.0.3071.104

but then my development system is a beast.

Well i think there is something misconfigured here.

For example this
rabatz ~ # genlop -t --date today go

A major jump of the chromium version. I have similar compile times w/ haswell 2 cores. It may also depend on your CXXFLAGS: High optimization requires long compilation times.

In case of overly long compile times, you may want to try to add the following to your /etc/make.conf:
MAKEOPTS="-jX"
Where X is the number of physical cores + 1

Particularly for AMD systems that should greatly speed up things.

There is (as always) one caveat: In case you run out of memory during compilation, you may need to reduce the number again.
For example, I had to do this for qt by adding
MAKEOPTS="-j1"
to /etc/portage/env/x11-libs/qt-core

Pfff it just took me 4 hours and 9 minutes to emerge www-client/chromium-62.0.3202.62 with an Intel i5 2500k ! Seriously?! More than 4 hours to build a web browser ?
Code:

thomas@gentoo log % sudo genlop -t chromium
 * www-client/chromium

I'm really considering getting rid of Chromium and finding an alternative browser.

I'm very happy with the Firefox 57 beta. The new Quantum engine is very fast. You can find ebuild in the mozilla overlay.
