ulimit is a per user setting. I am unsure how you are doing "setting `ulimit -d
unlimited` as root" to affect users (as it would only affect the current session
of root).
if you are using -current (what I assume as there is no mention) and
PORTS_PRIVSEP, the build user should have ~7Go of datasize, which should be
enough to pass the pre-configure test.
you could check you settings with:
- check PORTS_PRIVSEP configuration:
$ cd /usr/ports/lang/rust && make show=PORTS_PRIVSEP
Yes
$ cd /usr/ports/lang/rust && make show=BUILD_USER
_pbuild
- obtain the class of the user _pbuild
$ id -c _pbuild
pbuild
- obtain the soft datasize limit for the class pbuild
$ getcap -s datasize-cur -f /etc/login.conf pbuild
7168M
(or read /etc/login.conf file)
To change the limit, you should edit the right class in /etc/login.conf, and
change `datasize-cur' setting for this class.
Thanks.
