# # $FreeBSD$ # # The user-driven targets are: # # buildworld - Rebuild *everything*, including glue to help do # upgrades. # installworld - Install everything built by "buildworld". # world - buildworld + installworld. # update - Convenient way to update your source tree (cvs). # upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way # most - Build user commands, no libraries or include files. # installmost - Install user commands, no libraries or include files. # aout-to-elf - Upgrade an system from a.out to elf format (see below). # aout-to-elf-build - Build everything required to upgrade a system from # a.out to elf format (see below). # aout-to-elf-install - Install everything built by aout-to-elf-build (see # below). # move-aout-libs - Move the a.out libraries into an aout sub-directory # of each elf library sub-directory. # # This makefile is simple by design. The FreeBSD make automatically reads # the /usr/share/mk/sys.mk unless the -m argument is specified on the # command line. By keeping this makefile simple, it doesn't matter too # much how different the installed mk files are from those in the source # tree. This makefile executes a child make process, forcing it to use # the mk files from the source tree which are supposed to DTRT. # # The user-driven targets (as listed above) are implemented in Makefile.inc0 # and the private targets are in Makefile.inc1. These are kept separate # to help the bootstrap build from aout to elf format. # # For novices wanting to build from current sources, the simple instructions # are: # # 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. # 2. `cd /usr/src' (or to the directory containing your source tree). # 3. `make world' # # Be warned, this will update your installed system, except for configuration # files in the /etc directory and for the kernel. You have to do those manually. # # If at first you're a little nervous about having a `make world' update # your system, a `make buildworld' will build everything in the /usr/obj # tree without touching your installed system. To be of any further use # though, a `make installworld' is required. # # If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will # update the legacy support for aout. This includes all libraries, ld.so # and boot objects. This part of build should be regarded as # deprecated and you should _not_ expect to be able to do this past the # release of 4.0. You have exactly one major release to move entirely # to elf. # # ---------------------------------------------------------------------------- # # Upgrading an i386 system from a.out to elf format # # # The aout->elf transition build is performed by doing a `make upgrade' (or # `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed # by a `make aout-to-elf-install', depending on user preference. # You need to have at least 320 Mb of free space for the object tree. # # The upgrade process checks the installed release. If this is 3.0-CURRENT, # it is assumed that your kernel contains all the syscalls required by the # current sources. # # The upgrade procedure will stop and ask for confirmation to proceed # several times. On each occasion, you can type Ctrl-C to abort the # upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip # the confirmation steps. # # At the end of the upgrade procedure, /etc/objformat is created or # updated to contain OBJFORMAT=elf. From then on, you're elf by default. # # ---------------------------------------------------------------------------- # # # Define the user-driven targets.
