The FreeBSD make automatically reads 26219820Sjeff# the /usr/share/mk/sys.mk unless the -m argument is specified on the 27219820Sjeff# command line. By keeping this makefile simple, it doesn't matter too 28219820Sjeff# much how different the installed mk files are from those in the source 29219820Sjeff# tree. This makefile executes a child make process, forcing it to use 30219820Sjeff# the mk files from the source tree which are supposed to DTRT. 31219820Sjeff# 32219820Sjeff# The user-driven targets (as listed above) are implemented in Makefile.inc0 33219820Sjeff# and the private targets are in Makefile.inc1. These are kept separate 34219820Sjeff# to help the bootstrap build from aout to elf format. 35219820Sjeff# 36219820Sjeff# For novices wanting to build from current sources, the simple instructions 37219820Sjeff# are: 38219820Sjeff# 39219820Sjeff# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 40219820Sjeff# 2. `cd /usr/src' (or to the directory containing your source tree). 41219820Sjeff# 3. `make world' 42219820Sjeff# 43219820Sjeff# Be warned, this will update your installed system, except for configuration 44219820Sjeff# files in the /etc directory and for the kernel. You have to do those manually. 45219820Sjeff# 46219820Sjeff# If at first you're a little nervous about having a `make world' update 47219820Sjeff# your system, a `make buildworld' will build everything in the /usr/obj 48219820Sjeff# tree without touching your installed system. To be of any further use 49219820Sjeff# though, a `make installworld' is required. 50219820Sjeff# 51219820Sjeff# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 52219820Sjeff# update the legacy support for aout. This includes all libraries, ld.so 53219820Sjeff# and boot objects. This part of build should be regarded as 54219820Sjeff# deprecated and you should _not_ expect to be able to do this past the 55219820Sjeff# release of 4.0. You have exactly one major release to move entirely 56219820Sjeff# to elf. 57219820Sjeff# 58219820Sjeff# ---------------------------------------------------------------------------- 59219820Sjeff# 60219820Sjeff# Upgrading an i386 system from a.out to elf format 61219820Sjeff# 62219820Sjeff# 63219820Sjeff# The aout->elf transition build is performed by doing a `make upgrade' (or 64219820Sjeff# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 65219820Sjeff# by a `make aout-to-elf-install', depending on user preference. 66219820Sjeff# You need to have at least 320 Mb of free space for the object tree. 67219820Sjeff# 68219820Sjeff# The upgrade process checks the installed release. If this is 3.0-CURRENT, 69219820Sjeff# it is assumed that your kernel contains all the syscalls required by the 70219820Sjeff# current sources. 71219820Sjeff# 72219820Sjeff# The upgrade procedure will stop and ask for confirmation to proceed 73219820Sjeff# several times. On each occasion, you can type Ctrl-C to abort the 74219820Sjeff# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 75219820Sjeff# the confirmation steps. 76219820Sjeff# 77219820Sjeff# At the end of the upgrade procedure, /etc/objformat is created or 78219820Sjeff# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 79219820Sjeff# 80219820Sjeff# ---------------------------------------------------------------------------- 81219820Sjeff# 82219820Sjeff# 83219820Sjeff# Define the user-driven targets.
