is actually commented out there but i think i have something else that's
unneeded. but then those people in forums at
https://forums.freebsd.org/threads/error-trying-to-upgrade-to-version-15-current.97389/
have something else there that also affects this? i might need #2 or #3 time
of reading src.conf manpage to only use options that affect resulting build.
and which affect build size (main reason). build times decrease a lot too. but
i kept all options in file, ordered, for reference purposes, should i need to
turn them on or off
oh, i think WITHOUT_CROSS_COMPILER does it, it also turns
WITHOUT_ELFTOOLCHAIN_BOOTSTRAP on. i might have overlooked what all those
"compiler" options actually do. what i wanted is to exclude compilers from
resulting build target. not from build itself
did you spot any other options that affect build itself and not target?
i would guess pkgbase would eventually fix this "minimize the built system"
issues
or build options could have even better clearer documentation. tho i'm not that
good documenter myself maybe to help to improve it
actually the build system confuses me in more way too, as some variables are
make ones, some could be make or env, some only env. meh
