I thought I would try this on my 4-core machine - unfortunately, I
accidentally booted the old BLFS-8.3 system instead of the later
build, and had installed all the added extra dependencies before I
realised that.
This is a ryzen3 with 4 cores, and according to top 7.8 GiB of
memory and 6.0 GiB of swap.
Using 2.22.3 with the book's instructions for 2.22.2, and not
forcing NINJAJOBS because I figured running 4+2 jobs would probably
be ok, even if slightly slower than forcing 4). A DESTDIR install.
I was using X, firefox with about 34 tabs, falkon with about 5 tabs,
and 6 instances of urxvt.
These figures from free, and from du for the directory space,
probably give a fairly accurate indication of the space used.
Max real mem noted 7214692
Initial real mem 1363476 (includes the extracted tarball)
change 5851219
max swap 1339648
approx total mem 7190857 plus the build space
added directory space 616852
total 7807709 (7624MiB)
wkit space starts at 181884 (178MiB)
after install 658408 (643MiB)
change 476524
and the install 140328 (128MiB)
directory space at end 616852 (602MiB)
Summary - with (only) 4 jobs, 8GB RAM might be enough if nothing
else is running.
I'm _surprised_ that Christopher's machine OOM'd with a total of
14GB RAM+swap and "only" 6 cores (that implies 8 jobs by default in
ninja) - I guess that hyperthreading, if available, was turned off
so that 'top' only shows 8 CPUs.
