# This file documents the variables around the DESTDIR support.
|
||
|
|
#
|
||
|
|
# Normally, packages are installed directly into LOCALBASE and may
|
||
|
|
# overwrite files of other packages there. It also makes it easy to
|
||
|
|
# create packages which behave differently depending on whether they
|
||
|
|
# are installed from source or from a binary package. This is not good.
|
||
|
|
#
|
||
|
|
# The DESTDIR support tries to prevent some of these problems. When it
|
||
|
|
# is enabled, packages are not installed directly into LOCALBASE.
|
||
|
|
# Instead, they are installed in a temporary directory, and a binary
|
||
|
|
# package is created from the files that have been installed there.
|
||
|
|
#
|
||
|
|
# === User-settable variables ===
|
||
|
|
#
|
||
|
|
# USE_DESTDIR
|
||
|
|
# * "yes" to enable DESTDIR support for those packages that
|
||
|
|
# explicitly support it.
|
||
|
|
#
|
||
|
|
# * "full": This makes the build completely unprivileged and in
|
||
|
|
# turn detects any attempt to write e.g. to ${LOCALBASE}.
|
||
|
|
# This is not supported for actual installation yet, due to
|
||
|
|
# short comings of pkg_create. [FIXME]
|
||
|
|
#
|
||
|
|
# === Package-settable variables ===
|
||
|
|
#
|
||
|
|
# PKG_DESTDIR_SUPPORT
|
||
|
|
# * "user-destdir" means that all files of the packages should be
|
||
|
|
# installed with default ownership and permissions.
|
||
|
|
#
|
||
|
|
# * "destdir" means that some of the installed files need special
|
||
|
|
# ownership or permissions.
|
||
|
|
#
|
||
|
|
# === Implementation notes ===
|
||
|
|
#
|
||
|
|
# In the "install" phase, the variable DESTDIR is set in the make(1)
|
||
|
|
# environment of the default "do-install" target. Additionally, the
|
||
|
|
# variable is passed in the INSTALL_MAKE_FLAGS to override potential
|
||
|
|
# "DESTDIR=" entries in the Makefiles.
