4 # The user-driven targets are:
6 # buildworld - Rebuild *everything*, including glue to help do
8 # installworld - Install everything built by "buildworld".
9 # world - buildworld + installworld.
10 # buildkernel - Rebuild the kernel and the kernel-modules.
11 # installkernel - Install the kernel and the kernel-modules.
12 # reinstallkernel - Reinstall the kernel and the kernel-modules.
13 # update - Convenient way to update your source tree (cvs).
14 # upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way
15 # most - Build user commands, no libraries or include files.
16 # installmost - Install user commands, no libraries or include files.
17 # aout-to-elf - Upgrade an system from a.out to elf format (see below).
18 # aout-to-elf-build - Build everything required to upgrade a system from
19 # a.out to elf format (see below).
20 # aout-to-elf-install - Install everything built by aout-to-elf-build (see
22 # move-aout-libs - Move the a.out libraries into an aout sub-directory
23 # of each elf library sub-directory.
25 # This makefile is simple by design. The FreeBSD make automatically reads
26 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
27 # command line. By keeping this makefile simple, it doesn't matter too
28 # much how different the installed mk files are from those in the source
29 # tree. This makefile executes a child make process, forcing it to use
30 # the mk files from the source tree which are supposed to DTRT.
32 # The user-driven targets (as listed above) are implemented in Makefile.inc0
33 # and the private targets are in Makefile.inc1. These are kept separate
34 # to help the bootstrap build from aout to elf format.
36 # For novices wanting to build from current sources, the simple instructions
39 # 1. Ensure that your /usr/obj directory has at least 260 Mb of free space.
40 # 2. `cd /usr/src' (or to the directory containing your source tree).
43 # Be warned, this will update your installed system, except for configuration
44 # files in the /etc directory and for the kernel. You have to do those manually.
46 # If at first you're a little nervous about having a `make world' update
47 # your system, a `make buildworld' will build everything in the /usr/obj
48 # tree without touching your installed system. To be of any further use
49 # though, a `make installworld' is required.
51 # If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will
52 # update the legacy support for aout. This includes all libraries, ld.so
53 # and boot objects. This part of build should be regarded as
54 # deprecated and you should _not_ expect to be able to do this past the
55 # release of 4.0. You have exactly one major release to move entirely
58 # ----------------------------------------------------------------------------
60 # Upgrading an i386 system from a.out to elf format
63 # The aout->elf transition build is performed by doing a `make upgrade' (or
64 # `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed
65 # by a `make aout-to-elf-install', depending on user preference.
66 # You need to have at least 320 Mb of free space for the object tree.
68 # The upgrade process checks the installed release. If this is 3.0-CURRENT,
69 # it is assumed that your kernel contains all the syscalls required by the
72 # The upgrade procedure will stop and ask for confirmation to proceed
73 # several times. On each occasion, you can type Ctrl-C to abort the
74 # upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip
75 # the confirmation steps.
77 # At the end of the upgrade procedure, /etc/objformat is created or
78 # updated to contain OBJFORMAT=elf. From then on, you're elf by default.
