Reported by: Justin Gibbs. Add the move-aout-libs upgrade target so that people who have already gone elf can put their libraries through the mincer. Anyone who hasn't deleted aout libraries from /usr/lib (but has done a make world putting the new aout libs in /usr/lib/aout) will be asked for confirmation to delete them one by one.

# The user-driven targets are:
|
|
#
|
|
# buildworld - Rebuild *everything*, including glue to help do
|
|
# upgrades.
|
|
# installworld - Install everything built by "buildworld".
|
|
# world - buildworld + installworld.
|
|
# update - Convenient way to update your source tree (cvs).
|
|
# most - Build user commands, no libraries or include files.
|
|
# installmost - Install user commands, no libraries or include files.
|
|
# aout-to-elf - Upgrade an system from a.out to elf format (see below).
|
|
# aout-to-elf-build - Build everything required to upgrade a system from
|
|
# a.out to elf format (see below).
|
|
# aout-to-elf-install - Install everything built by aout-to-elf-build (see
|
|
# below).
|
|
# move-aout-libs - Move the a.out libraries into an aout sub-directory
|
|
# of each elf library sub-directory.
|
|
#
|
|
# This makefile is simple by design. The FreeBSD make automatically reads
|
|
# the /usr/share/mk/sys.mk unless the -m argument is specified on the
|
|
# command line. By keeping this makefile simple, it doesn't matter too
|
|
# much how different the installed mk files are from those in the source
|
|
# tree. This makefile executes a child make process, forcing it to use
|
|
# the mk files from the source tree which are supposed to DTRT.
|
|
#
|
|
# The user-driven targets (as listed above) are implemented in Makefile.inc0
|
|
# and the private targets are in Makefile.inc1. These are kept separate
|
|
# to help the bootstrap build from aout to elf format.
|
|
#
|
|
# For novices wanting to build from current sources, the simple instructions
|
|
# are:
|
|
#
|
|
# 1. Ensure that your /usr/obj directory has at least 165 Mb of free space.
|
|
# 2. `cd /usr/src' (or to the directory containing your source tree).
|
|
# 3. `make world'
|
|
#
|
|
# Be warned, this will update your installed system, except for configuration
|
|
# files in the /etc directory. You have to do those manually.
|
|
#
|
|
# If at first you're a little nervous about having a `make world' update
|
|
# your system, a `make buildworld' will build everything in the /usr/obj
|
|
# tree without touching your installed system. To be of any further use
|
|
# though, a `make installworld' is required.
|
|
#
|
|
# The `make world' process always follows the installed object format.
|
|
# This is set by creating /etc/objformat containing either OBJFORMAT=aout
|
|
# or OBJFORMAT=elf. If this file does not exist, the object format defaults
|
|
# to aout. This is expected to be changed to elf just prior to the release
|
|
# or 3.0. If OBJFORMAT is set as an environment variable or in /etc/make.conf,
|
|
# this overrides /etc/objformat.
|
|
#
|
|
# Unless -DNOAOUT is specified, a `make world' with OBJFORMAT=elf will
|
|
# update the legacy support for aout. This includes all libraries, ld.so,
|
|
# lkms and boot objects. This part of build should be regarded as
|
|
# deprecated and you should _not_ expect to be able to do this past the
|
|
# release of 3.1. You have exactly one major release to move entirely
|
|
# to elf.

|
#
|
|
# Upgrading an i386 system from a.out to elf format
|
|
#
|
|
#
|
|
# The aout->elf transition build is performed by doing a `make aout-to-elf'
|
|
# or a `make aout-to-elf-build' followed by a `make aout-to-elf-install'.
|
|
# You need to have at least 320 Mb of free space for the object tree.
|
|
#
|
|
# The upgrade process checks the installed release. If this is 3.0-CURRENT,
|
|
# it is assumed that your kernel contains all the syscalls required by the
|
|
# current sources.
|
|
#
|
|
# For installed systems where `uname -r' reports something other than
|
|
# 3.0-CURRENT, the upgrade process expects to build a kernel using the
|
|
# kernel configuration file sys/i386/conf/GENERICupgrade. This file is
|
|
# defaulted to the GENERIC kernel configuration file on the assumption that
|
|
# it will be suitable for most systems. Before performing the upgrade,
|
|
# replace sys/i386/conf/GENERICupgrade with your own version if your
|
|
# hardware requires a different configuration.
|
|
#
|
|
# The upgrade procedure will stop and ask for confirmation to proceed
|
|
# several times. On each occasion, you can type Ctrl-C to abort the
|
|
# upgrade.
|
|
#
|
|
# At the end of the upgrade procedure, /etc/objformat is created or
|
|
# updated to contain OBJFORMAT=elf. From then on, you're elf by default.
