But I also found that poudriere:
[88:53:28] Failed ports: www/chromium:build/timeout
 
So I will search how do I increase build time to avoid timeout:
---
# This defines the max time (in seconds) that a command may run for a build
# before it is killed for taking too long. Default: 86400
#MAX_EXECUTION_TIME=86400
---
 
I suspect it can be the cause of build failure because build >24h.

Hello all,
 
I'm running 13-STABLE on rpi4 8 and since firefox{-esr} is constantly tab crashing and seg faulting I decided to give chromium a try.
chromium pkg isn't available for arm64 and I didn't found error log at 
https://pkg-status.freebsd.org/ so I decided to build it on poudriere.
 
It fails to build around 70% but my biggest concern is build time: 27 hours for 70% compilation!
 
Just for comparison:
llvm15: 12h
rust: 9h
firefox: 6h
 
rip4 v1.5 8GB @ 2000Hz ~62 Celsius
zfs
poudriere:
USE_TMPFS=no
PARALLEL_JOBS=1
ALLOW_MAKE_JOBS=yes
 
Any hints on how to speed build? ccache?
Does cflags "-O -pipe" not present in compilation is related to build time? 
 
Full log:
https://people.freebsd.org/~eduardo/logs/chromium/chromium-113.0.5672.126.log
 
Thanks!

Hi,

My poudriere.conf for building ports on rpi4 contains these two changes:

# This defines the max time (in seconds) that a command may run for a build
# before it is killed for taking too long. Default: 86400
#MAX_EXECUTION_TIME=86400
MAX_EXECUTION_TIME=172800

# This defines the time (in seconds) before a command is considered to
# be in a runaway state for having no output on stdout. Default: 7200
#NOHANG_TIME=7200
NOHANG_TIME=172800


I'm maintaining some mongodb ports which also take a long long time to build on 
rpi4.
But I don't remember which of these settings has the preferred impact on your 
situation.

Oh... now I'm reading your log better. It contains this:
"=>> Killing timed out build after 86400 seconds"

And some time later:
"=>> Cleaning up wrkdir
===> Cleaning for chromium-113.0.5672.126"

So the errors about missing files happen because poudriere is removing files 
while some processes of the build are still running.

I'm curious how far it gets after you increase MAX_EXECUTION_TIME.

Regards,
Ronald.
