Beware anyone building lang/ghc-8.8.3 from the ports tree. Building it
here on FreeBSD 12.1-REL AMD64 with Poudriere, the build ran out of swap,
despite the PC having 8 GB RAM, 8 GB swap and not much else running.
My /usr/local/etc/poudriere.conf:
BASEFS=/poudriere
ZPOOL=zroot
FREEBSD_HOST=http://mirror.internode.net/
POUDRIERE_DATA=/poudriere/data
RESOLV_CONF=/etc/resolv.conf
DISTFILES_CACHE=/usr/ports/distfiles
USE_TMPFS=yes
ALLOW_MAKE_JOBS=yes
KEEP_OLD_PACKAGES=yes
PARALLEL_JOBS=8
Maybe I can retune the last three parameters to use less memory. I've not
tried yet.
This isn't really a whinge, I'm just surprised it failed. I'd have thought
8 GB was enough.
(ghc is a build dependency of textproc/hs-pandoc)
Did you have something else building at the same time?
On my laptop with 16 Gb of RAM I also see OOM failures when building
multiple "heavy" packages (llvmXX, gccX, ghc, rust, libreoffice)
simultaneously. In this case I use -J poudriere option to limit number of
jobs.
Nothing else building.
This is a headless server, so I've no need to build something the size of
libreoffice or chromium. I've noticed llvm10 takes a long time to build, but
8 GB seems plenty of memory for it.
The -J option sounds like the way to go, provided I remember to use it
next time. Or I could instead set PARALLEL_JOBS=1 in poudriere.conf but then
build performance will suffer for every port, which isn't ideal.
But perhaps there's an option to limit make jobs just for a single port, set in
/usr/local/etc/poudriere.d/make.conf ? That would be nice.
You can do it for OPTIONS in make.conf (or poudriere make/set .conf's):
# Per port options
# category_portname_{UN}SET=<OPTION>[ OPTION ]
graphics_cairo_UNSET=OPENGL
graphics_cairo_SET=X11
This doesn't help for non-OPTIONS variables, but we have this recently
submitted feature/review:
https://reviews.freebsd.org/D24324
For use like:
devel_llvm80_VARS=DISABLE_MAKE_JOBS=yes
devel_llvm90_VARS=DISABLE_MAKE_JOBS=yes
This would satisfy this and other per-port specific build options cases.
