5 # The user-driven targets are:
7 # buildworld - Rebuild *everything*, including glue to help do
9 # quickworld - Skip bootstrap, build and cross-build tool steps
10 # realquickworld - Skip above steps, plus depend
11 # crossworld - Just do the bootstrap, build, and cross-build steps
12 # installworld - Install everything built by "buildworld".
13 # world - buildworld + installworld.
14 # buildkernel - Rebuild the kernel and the kernel-modules.
15 # installkernel - Install the kernel and the kernel-modules.
16 # reinstallkernel - Reinstall the kernel and the kernel-modules.
17 # kernel - buildkernel + installkernel.
18 # update - Convenient way to update your source tree (cvs).
19 # upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way
20 # most - Build user commands, no libraries or include files.
21 # installmost - Install user commands, no libraries or include files.
22 # aout-to-elf - Upgrade an system from a.out to elf format (see below).
23 # aout-to-elf-build - Build everything required to upgrade a system from
24 # a.out to elf format (see below).
25 # aout-to-elf-install - Install everything built by aout-to-elf-build (see
27 # move-aout-libs - Move the a.out libraries into an aout sub-directory
28 # of each elf library sub-directory.
30 # This makefile is simple by design. The FreeBSD make automatically reads
31 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
32 # command line. By keeping this makefile simple, it doesn't matter too
33 # much how different the installed mk files are from those in the source
34 # tree. This makefile executes a child make process, forcing it to use
35 # the mk files from the source tree which are supposed to DTRT.
37 # The user-driven targets (as listed above) are implemented in Makefile.inc1.
39 # If you want to build your system from source be sure that /usr/obj has
40 # at least 400MB of diskspace available.
42 # For individuals wanting to build from the sources currently on their
43 # system, the simple instructions are:
45 # 1. `cd /usr/src' (or to the directory containing your source tree).
48 # For individuals wanting to upgrade their sources (even if only a
49 # delta of a few days):
51 # 1. `cd /usr/src' (or to the directory containing your source tree).
52 # 2. `make buildworld'
53 # 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
54 # 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
55 # 5. `reboot' (in single user mode: boot -s from the loader prompt).
57 # 7. `make installworld'
61 # See src/UPDATING `COMMON ITEMS' for more complete information.
63 # If TARGET_ARCH=arch (e.g. alpha) is specified you can
64 # cross build world for other architectures using the buildworld target,
65 # and once the world is built you can cross build a kernel using the

70 # Upgrading an i386 system from a.out to elf format
73 # The aout->elf transition build is performed by doing a `make upgrade' (or
74 # `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed
75 # by a `make aout-to-elf-install', depending on user preference.
76 # You need to have at least 320 Mb of free space for the object tree.
78 # The upgrade process checks the installed release. If this is 3.0-CURRENT,
79 # it is assumed that your kernel contains all the syscalls required by the
82 # The upgrade procedure will stop and ask for confirmation to proceed
83 # several times. On each occasion, you can type Ctrl-C to abort the
84 # upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip
85 # the confirmation steps.
