The FreeBSD make automatically reads 26191418Srwatson# the /usr/share/mk/sys.mk unless the -m argument is specified on the 27191418Srwatson# command line. By keeping this makefile simple, it doesn't matter too 28191418Srwatson# much how different the installed mk files are from those in the source 29191418Srwatson# tree. This makefile executes a child make process, forcing it to use 30191418Srwatson# the mk files from the source tree which are supposed to DTRT. 31191418Srwatson# 32191418Srwatson# The user-driven targets (as listed above) are implemented in Makefile.inc0 33191418Srwatson# and the private targets are in Makefile.inc1. These are kept separate 34191418Srwatson# to help the bootstrap build from aout to elf format. 35191418Srwatson# 36191418Srwatson# For novices wanting to build from current sources, the simple instructions 37191418Srwatson# are: 38191418Srwatson# 39191418Srwatson# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 40191418Srwatson# 2. `cd /usr/src' (or to the directory containing your source tree). 41191418Srwatson# 3. `make world' 42191418Srwatson# 43191418Srwatson# Be warned, this will update your installed system, except for configuration 44191418Srwatson# files in the /etc directory and for the kernel. You have to do those manually. 45191418Srwatson# 46191418Srwatson# If at first you're a little nervous about having a `make world' update 47191418Srwatson# your system, a `make buildworld' will build everything in the /usr/obj 48191418Srwatson# tree without touching your installed system. To be of any further use 49191418Srwatson# though, a `make installworld' is required. 50191418Srwatson# 51191418Srwatson# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 52191418Srwatson# update the legacy support for aout. This includes all libraries, ld.so 53191418Srwatson# and boot objects. This part of build should be regarded as 54191418Srwatson# deprecated and you should _not_ expect to be able to do this past the 55191418Srwatson# release of 4.0. You have exactly one major release to move entirely 56191418Srwatson# to elf. 57191418Srwatson# 58191418Srwatson# ---------------------------------------------------------------------------- 59191418Srwatson# 60191418Srwatson# Upgrading an i386 system from a.out to elf format 61191418Srwatson# 62191418Srwatson# 63191418Srwatson# The aout->elf transition build is performed by doing a `make upgrade' (or 64191418Srwatson# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 65191418Srwatson# by a `make aout-to-elf-install', depending on user preference. 66191418Srwatson# You need to have at least 320 Mb of free space for the object tree. 67191418Srwatson# 68191418Srwatson# The upgrade process checks the installed release. If this is 3.0-CURRENT, 69191418Srwatson# it is assumed that your kernel contains all the syscalls required by the 70191418Srwatson# current sources. 71191418Srwatson# 72191418Srwatson# The upgrade procedure will stop and ask for confirmation to proceed 73191418Srwatson# several times. On each occasion, you can type Ctrl-C to abort the 74191418Srwatson# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 75191418Srwatson# the confirmation steps. 76191418Srwatson# 77191418Srwatson# At the end of the upgrade procedure, /etc/objformat is created or 78191418Srwatson# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 79191418Srwatson# 80191418Srwatson# ---------------------------------------------------------------------------- 81191418Srwatson# 82191418Srwatson# 83191418Srwatson# Define the user-driven targets.
