"""Install Debian sysroots for building chromium.
|
||||
"""
|
||||
|
||||
# The sysroot is needed to ensure that binaries that get built will run on
|
||||
# the oldest stable version of Debian that we currently support.
|
||||
# This script can be run manually but is more often run as part of gclient
|
||||
# hooks. When run from hooks this script is a no-op on non-linux platforms.
|
||||
|
||||
# The sysroot image could be constructed from scratch based on the current state
|
||||
# of the Debian archive but for consistency we use a pre-built root image (we
|
||||
# don't want upstream changes to Debian to effect the chromium build until we
|
||||
# choose to pull them in). The images will normally need to be rebuilt every
|
||||
# time chrome's build dependencies are changed but should also be updated
|
||||
# periodically to include upstream security fixes from Debian.
