while building icefish_9.0.3 i got error

Count only your available RAM, not swap. Otherwise it is goint to be really tight.

I think you could be OK with something like -l12 -j 8, but still there could be peaks that would make swap enter often, so -l 12 -j 6 could be required.

I have 12 core hardware device having 16 GB RAM and 16 GB swap memory is it possible to build the AGL build for chromium ?
i added PARALLEL_MAKE_pn-chromium68= "-l 12 -j 10" in local.conf file is it right?

Please help me.....

Yes, this is RAM issue. For building Chromium you need RAM, at a rate of 2-3GB per compilation core. This is only for compilation, then you need more RAM for the rest of the system, and other compilation activities (i.e. other Yocto tasks).

A mitigation for that I use here (40 cores, but 64GB of RAM), is limiting the number of cores AND the creation of build activities when workload is high:

In your case it would be PARALLEL_MAKE_pn-chromium68. About the numbers, -l would match the core numbers, and -j should be the minimum of half the number of concurrent threads in your system and half the GB of RAM available. Some examples:

• 2 cores with hyperthreading, so 4 concurrent threads, 8GB RAM: -l 4 -j 4 (default value).

• 4 cores with hyperthreading, so 8 concurrent threads, 24GB RAM: -l 8 -j 8

• 10 cores with hyperthreading, so 20 concurrent threads, 32GB RAM: -l 20 -j 16

Closing as WONTFIX. @Jan-Simon Moeller < Is there anything that can be done at recipe level to apply these heuristics automatically but still allowing to override from local.dev.conf?

when i run the "dmesg" command in terminal i got this logs

[ 945.897023]Out of memory: Killed process 7033 (cc1plus) total-vm:1655832kB, anon-rss:1606252kB, file-rss:0kB, shmem-rss:0kB, UID:1000 pgtables:3272kB oom_score_adj:0
[ 945.936398] oom_reaper: reaped process 7033 (cc1plus), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB

Is it the RAM issue?

I have attached the complete log file of the error above.
