The FreeBSD make automatically reads 2538666Sjb# the /usr/share/mk/sys.mk unless the -m argument is specified on the 2638666Sjb# command line. By keeping this makefile simple, it doesn't matter too 2738666Sjb# much how different the installed mk files are from those in the source 2838666Sjb# tree. This makefile executes a child make process, forcing it to use 2938666Sjb# the mk files from the source tree which are supposed to DTRT. 3017308Speter# 3138666Sjb# The user-driven targets (as listed above) are implemented in Makefile.inc0 3238666Sjb# and the private targets are in Makefile.inc1. These are kept separate 3338666Sjb# to help the bootstrap build from aout to elf format. 3419175Sbde# 3538666Sjb# For novices wanting to build from current sources, the simple instructions 3638666Sjb# are: 3738042Sbde# 3839726Sjb# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 3938666Sjb# 2. `cd /usr/src' (or to the directory containing your source tree). 4038666Sjb# 3. `make world' 4138042Sbde# 4238666Sjb# Be warned, this will update your installed system, except for configuration 4349315Shoek# files in the /etc directory and for the kernel. You have to do those manually. 4417308Speter# 4538666Sjb# If at first you're a little nervous about having a `make world' update 4638666Sjb# your system, a `make buildworld' will build everything in the /usr/obj 4738666Sjb# tree without touching your installed system. To be of any further use 4838666Sjb# though, a `make installworld' is required. 4917308Speter# 5045108Sobrien# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 5142128Speter# update the legacy support for aout. This includes all libraries, ld.so 5242128Speter# and boot objects. This part of build should be regarded as 5338666Sjb# deprecated and you should _not_ expect to be able to do this past the 5451361Sjb# release of 4.0. You have exactly one major release to move entirely 5538666Sjb# to elf. 5617308Speter# 5738666Sjb# ---------------------------------------------------------------------------- 5817308Speter# 5938666Sjb# Upgrading an i386 system from a.out to elf format 6017308Speter# 6127910Sasami# 6243226Sjkh# The aout->elf transition build is performed by doing a `make upgrade' (or 6343226Sjkh# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 6443226Sjkh# by a `make aout-to-elf-install', depending on user preference. 6538666Sjb# You need to have at least 320 Mb of free space for the object tree. 6627910Sasami# 6738666Sjb# The upgrade process checks the installed release. If this is 3.0-CURRENT, 6838666Sjb# it is assumed that your kernel contains all the syscalls required by the 6938666Sjb# current sources. 7027910Sasami# 7138666Sjb# The upgrade procedure will stop and ask for confirmation to proceed 7238666Sjb# several times. On each occasion, you can type Ctrl-C to abort the 7343226Sjkh# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 7443226Sjkh# the confirmation steps. 7527910Sasami# 7638666Sjb# At the end of the upgrade procedure, /etc/objformat is created or 7738666Sjb# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 7827910Sasami# 7938666Sjb# ---------------------------------------------------------------------------- 8027910Sasami# 8117308Speter# 8238666Sjb# Define the user-driven targets.
