The FreeBSD make automatically reads 2638666Sjb# the /usr/share/mk/sys.mk unless the -m argument is specified on the 2738666Sjb# command line. By keeping this makefile simple, it doesn't matter too 2838666Sjb# much how different the installed mk files are from those in the source 2938666Sjb# tree. This makefile executes a child make process, forcing it to use 3038666Sjb# the mk files from the source tree which are supposed to DTRT. 3117308Speter# 3238666Sjb# The user-driven targets (as listed above) are implemented in Makefile.inc0 3338666Sjb# and the private targets are in Makefile.inc1. These are kept separate 3438666Sjb# to help the bootstrap build from aout to elf format. 3519175Sbde# 3638666Sjb# For novices wanting to build from current sources, the simple instructions 3738666Sjb# are: 3838042Sbde# 3939726Sjb# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 4038666Sjb# 2. `cd /usr/src' (or to the directory containing your source tree). 4138666Sjb# 3. `make world' 4238042Sbde# 4338666Sjb# Be warned, this will update your installed system, except for configuration 4449315Shoek# files in the /etc directory and for the kernel. You have to do those manually. 4517308Speter# 4638666Sjb# If at first you're a little nervous about having a `make world' update 4738666Sjb# your system, a `make buildworld' will build everything in the /usr/obj 4838666Sjb# tree without touching your installed system. To be of any further use 4938666Sjb# though, a `make installworld' is required. 5017308Speter# 5145108Sobrien# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 5242128Speter# update the legacy support for aout. This includes all libraries, ld.so 5342128Speter# and boot objects. This part of build should be regarded as 5438666Sjb# deprecated and you should _not_ expect to be able to do this past the 5551361Sjb# release of 4.0. You have exactly one major release to move entirely 5638666Sjb# to elf. 5717308Speter# 5838666Sjb# ---------------------------------------------------------------------------- 5917308Speter# 6038666Sjb# Upgrading an i386 system from a.out to elf format 6117308Speter# 6227910Sasami# 6343226Sjkh# The aout->elf transition build is performed by doing a `make upgrade' (or 6443226Sjkh# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 6543226Sjkh# by a `make aout-to-elf-install', depending on user preference. 6638666Sjb# You need to have at least 320 Mb of free space for the object tree. 6727910Sasami# 6838666Sjb# The upgrade process checks the installed release. If this is 3.0-CURRENT, 6938666Sjb# it is assumed that your kernel contains all the syscalls required by the 7038666Sjb# current sources. 7127910Sasami# 7238666Sjb# The upgrade procedure will stop and ask for confirmation to proceed 7338666Sjb# several times. On each occasion, you can type Ctrl-C to abort the 7443226Sjkh# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 7543226Sjkh# the confirmation steps. 7627910Sasami# 7738666Sjb# At the end of the upgrade procedure, /etc/objformat is created or 7838666Sjb# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 7927910Sasami# 8038666Sjb# ---------------------------------------------------------------------------- 8127910Sasami# 8217308Speter# 8338666Sjb# Define the user-driven targets.
