#
|
|
# The target order is always: pre-chroot do-chroot post-chroot
|
|
#
|
|
# pre-chroot
|
|
# - You can use this for special preparation work, that
|
|
# want to do before chrooting into the destination
|
|
# environment and doing the real build. At default
|
|
# this target is empty.
|
|
#
|
|
# do-chroot
|
|
# - This is the main target for doing the chrooted
|
|
# operations. It mounts the ports tree and devfs into
|
|
# the destination environment and starts make(1)
|
|
# by calling chroot(1).
|
|
#
|
|
# post-chroot
|
|
# - This target runs chrooted just after chroot(1) was
|
|
# called. You can use this for special preparation
|
|
# work for the chrooted build if necessary. At
|
|
# default, this target is empty.
|
|
#
|
|
# DESTDIR_ENV_LIST
|
|
# - Contains names of the variables in host environ(7),
|
|
# which should be imported into the chrooted environ
|
|
# along with their values.
|
|
# Default: empty.
|
|
#
|
|
# DESTDIR_MOUNT_LIST
|
|
# - Contains the directories to mount into the
|
|
# destination. This is to make PORTSDIR, DISTDIR, etc.
|
|
# available in the destination environment. Three
|
|
# forms of entries are allowed:
|
|
# VAR
|
|
# - Mounts the path contained by VAR into
|
|
# a temporary directory and sets VAR to that
|
|
# directory in the destination environ(7).
|
|
# VAR:HOST_PATH
|
|
# - Mounts HOST_PATH to a a temporary directory
|
|
# and sets VAR to that directory in the
|
|
# destination environ(7).
|
|
# VAR:HOST_PATH:DEST_PATH
|
|
# - Mounts HOST_PATH to DEST_PATH and sets VAR
|
|
# to DEST_PATH in the destination environ(7).
|
|
# Default: PORTSDIR DISTDIR
|
|
#
|
|
# You can use something like this in host /etc/make.conf to
|
|
# customize per-chroot environment:
|
|
# .if ${DESTDIR}=/foo/bar
|
|
# PREFIX=/opt
|
|
# CFLAGS=-O3 -pipe
|
|
# DESTDIR_ENV_LIST=PREFIX CFLAGS
