# # $FreeBSD: src/Makefile,v 1.234.2.19 2003/04/16 09:59:40 ru Exp $ # $DragonFly: src/Makefile,v 1.3 2003/11/19 01:05:31 dillon Exp $ # # The user-driven targets are: # # buildworld - Rebuild *everything*, including glue to help do # upgrades. # installworld - Install everything built by "buildworld". # world - buildworld + installworld. # buildkernel - Rebuild the kernel and the kernel-modules. # installkernel - Install the kernel and the kernel-modules. # reinstallkernel - Reinstall the kernel and the kernel-modules. # kernel - buildkernel + installkernel. # 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.inc1. # # If you want to build your system from source be sure that /usr/obj has # at least 400MB of diskspace available. # # For individuals wanting to build from the sources currently on their # system, the simple instructions are: # # 1. `cd /usr/src' (or to the directory containing your source tree). # 2. `make world' # # For individuals wanting to upgrade their sources (even if only a # delta of a few days): # # 1. `cd /usr/src' (or to the directory containing your source tree). # 2. `make buildworld' # 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). # 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). # 5. `reboot' (in single user mode: boot -s from the loader prompt). # 6. `mergemaster -p' # 7. `make installworld' # 8. `mergemaster' # 9. `reboot' # # See src/UPDATING `COMMON ITEMS' for more complete information. # # 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. # # If TARGET_ARCH=arch (e.g. alpha) is specified you can # cross build world for other architectures using the buildworld target, # and once the world is built you can cross build a kernel using the # buildkernel target. # # ---------------------------------------------------------------------------- # # 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.
