The FreeBSD make automatically reads 271558Srgrimes# the /usr/share/mk/sys.mk unless the -m argument is specified on the 281558Srgrimes# command line. By keeping this makefile simple, it doesn't matter too 291558Srgrimes# much how different the installed mk files are from those in the source 301558Srgrimes# tree. This makefile executes a child make process, forcing it to use 311558Srgrimes# the mk files from the source tree which are supposed to DTRT. 321558Srgrimes# 331558Srgrimes# The user-driven targets (as listed above) are implemented in Makefile.inc0 3423669Speter# and the private targets are in Makefile.inc1. These are kept separate 3596707Strhodes# to help the bootstrap build from aout to elf format. 361558Srgrimes# 371558Srgrimes# For novices wanting to build from current sources, the simple instructions 381558Srgrimes# are: 391558Srgrimes# 401558Srgrimes# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 411558Srgrimes# 2. `cd /usr/src' (or to the directory containing your source tree). 421558Srgrimes# 3. `make world' 43164911Sdwmalone# 44204111Suqs# Be warned, this will update your installed system, except for configuration 451558Srgrimes# files in the /etc directory and for the kernel. You have to do those manually. 461558Srgrimes# 4735852Sjkh# If at first you're a little nervous about having a `make world' update 481558Srgrimes# your system, a `make buildworld' will build everything in the /usr/obj 491558Srgrimes# tree without touching your installed system. To be of any further use 501558Srgrimes# though, a `make installworld' is required. 511558Srgrimes# 521558Srgrimes# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 531558Srgrimes# update the legacy support for aout. This includes all libraries, ld.so 5423669Speter# and boot objects. This part of build should be regarded as 55102231Strhodes# deprecated and you should _not_ expect to be able to do this past the 561558Srgrimes# release of 4.0. You have exactly one major release to move entirely 571558Srgrimes# to elf. 581558Srgrimes# 591558Srgrimes# ---------------------------------------------------------------------------- 601558Srgrimes# 611558Srgrimes# Upgrading an i386 system from a.out to elf format 621558Srgrimes# 631558Srgrimes# 64144099Simp# The aout->elf transition build is performed by doing a `make upgrade' (or 651558Srgrimes# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 661558Srgrimes# by a `make aout-to-elf-install', depending on user preference. 67102231Strhodes# You need to have at least 320 Mb of free space for the object tree. 681558Srgrimes# 691558Srgrimes# The upgrade process checks the installed release. If this is 3.0-CURRENT, 701558Srgrimes# it is assumed that your kernel contains all the syscalls required by the 711558Srgrimes# current sources. 721558Srgrimes# 731558Srgrimes# The upgrade procedure will stop and ask for confirmation to proceed 741558Srgrimes# several times. On each occasion, you can type Ctrl-C to abort the 751558Srgrimes# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 761558Srgrimes# the confirmation steps. 771558Srgrimes# 781558Srgrimes# At the end of the upgrade procedure, /etc/objformat is created or 791558Srgrimes# updated to contain OBJFORMAT=elf.
