The FreeBSD make automatically reads 231541Srgrimes# the /usr/share/mk/sys.mk unless the -m argument is specified on the 241541Srgrimes# command line. By keeping this makefile simple, it doesn't matter too 251541Srgrimes# much how different the installed mk files are from those in the source 261541Srgrimes# tree. This makefile executes a child make process, forcing it to use 271541Srgrimes# the mk files from the source tree which are supposed to DTRT. 281541Srgrimes# 291541Srgrimes# The user-driven targets (as listed above) are implemented in Makefile.inc0 301541Srgrimes# and the private targets are in Makefile.inc1. These are kept separate 311541Srgrimes# to help the bootstrap build from aout to elf format. 321541Srgrimes# 331541Srgrimes# For novices wanting to build from current sources, the simple instructions 3422521Sdyson# are: 3550477Speter# 361541Srgrimes# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 371541Srgrimes# 2. `cd /usr/src' (or to the directory containing your source tree). 381541Srgrimes# 3. `make world' 397430Sbde# 4060041Sphk# Be warned, this will update your installed system, except for configuration 411541Srgrimes# files in the /etc directory and for the kernel. You have to do those manually. 421541Srgrimes# 431541Srgrimes# If at first you're a little nervous about having a `make world' update 441541Srgrimes# your system, a `make buildworld' will build everything in the /usr/obj 45297633Strasz# tree without touching your installed system. To be of any further use 461541Srgrimes# though, a `make installworld' is required. 4762976Smckusick# 481541Srgrimes# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 49202283Slulf# update the legacy support for aout. This includes all libraries, ld.so 50254260Spfg# and boot objects. This part of build should be regarded as 51202283Slulf# deprecated and you should _not_ expect to be able to do this past the 52254260Spfg# release of 4.0. You have exactly one major release to move entirely 53251344Spfg# to elf. 54202283Slulf# 551541Srgrimes# ---------------------------------------------------------------------------- 56254260Spfg# 57254260Spfg# Upgrading an i386 system from a.out to elf format 581541Srgrimes# 59202283Slulf# 601541Srgrimes# The aout->elf transition build is performed by doing a `make upgrade' (or 611541Srgrimes# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 621541Srgrimes# by a `make aout-to-elf-install', depending on user preference. 631541Srgrimes# You need to have at least 320 Mb of free space for the object tree. 64246634Spfg# 651541Srgrimes# The upgrade process checks the installed release. If this is 3.0-CURRENT, 66254283Spfg# it is assumed that your kernel contains all the syscalls required by the 6792363Smckusick# current sources. 6892363Smckusick# 691541Srgrimes# The upgrade procedure will stop and ask for confirmation to proceed 701541Srgrimes# several times. On each occasion, you can type Ctrl-C to abort the 711541Srgrimes# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 721541Srgrimes# the confirmation steps. 73137726Sphk# 74137726Sphk# At the end of the upgrade procedure, /etc/objformat is created or 751541Srgrimes# updated to contain OBJFORMAT=elf.
