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 260 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 and for the kernel. 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. +# +# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will +# update the legacy support for aout. This includes all libraries, ld.so +# 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 4.0. 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 upgrade' (or +# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed +# by a `make aout-to-elf-install', depending on user preference. +# 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. +# +# 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. Optionally, you can also start it with NOCONFIRM=yes and skip +# the confirmation steps. +# +# 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. +# +# ---------------------------------------------------------------------------- +# +# +# Define the user-driven targets.
