NAME

build -- information on how to build the system

DESCRIPTION

The source for the DragonFly system and applications is located in /usr/src. This directory contains the ``base system'' sources, which is loosely defined as the things required to rebuild the system to a useful state. It also contains the source for the system documentation, includ- ing manual pages. Refer to development(7) for more information on how to obtain the DragonFly sources. Third party applications have to be built using the dports(7) system. The file /usr/Makefile has targets for obtaining the dports tree. Typing make in /usr gives specifics on how to obtain the tree for building pack- ages. The make(1) command is used in /usr/src to build and install the things in that directory. Issuing the make(1) command in any directory or sub- directory of those directories has the same effect as issuing the same command in all subdirectories of that directory. With no target speci- fied, the things in that directory are just built. The following list provides the names and actions for other targets: clean Removes any files created during the build process. install Installs the results of the build for this directory. The other /usr/src make targets are: buildworld Rebuild everything but the kernel. quickworld Same as buildworld, but skip bootstrap, build and cross-build tool steps. This target can be used for incremental upgrades once a full build of the world has been done with buildworld. realquickworld Same as quickworld, but also skip the depend step. crossworld Just do the bootstrap, build and cross-build steps. installworld Install everything built by buildworld. world buildworld * installworld. buildkernel Rebuild the kernel and the kernel-modules. nativekernel Rebuild the kernel and the kernel-modules using native tools. quickkernel Same as buildkernel, but skip the depend step and do not clean out the obj modules. This target can be used for incremental upgrades once a full build of the kernel has been done with buildkernel. installkernel Install the kernel and the kernel-modules. reinstallkernel Reinstall the kernel and the kernel-modules. kernel buildkernel * installkernel. preupgrade Perform certain upgrades that have to be done before installworld. installworld will complain if they have not been done. upgrade Upgrade the files in /etc and also setup the rest of the system for the version of DragonFly just installed. most Build user commands, no libraries or include files. installmost Install user commands, no libraries or include files. backupworld Manually archive binaries from installed world to location specified by WORLD_BACKUP. backup-clean Delete archive created by backupworld. backup-auto-clean Delete archive created automatically during installworld. restoreworld Restore binaries from archive created by backupworld. restoreworld-auto Restore binaries from archive created automatically during installworld. The archive location is speci- fied by AUTO_BACKUP.

ENVIRONMENT

TARGET_ARCH, TARGET_PLATFORM The target machine processor architecture and hardware platform. These have to be set for cross-building. TARGET_ARCH is analogous to the ``uname -p'' output. To build for the 32 bit Intel architecture known as IA-32, x86 or x86-32, use: TARGET_ARCH=i386 TARGET_PLATFORM=pc32 For the 64 bit AMD architecture known as AMD64, x86-64 or Intel 64, use: TARGET_ARCH=x86_64 TARGET_PLATFORM=pc64 DESTDIR An existing directory to be the root of the hierarchy where the resulting binaries will be installed (the default is /). MAKEOBJDIRPREFIX The directory hierarchy where the object files will be built (the default is /usr/obj). __MAKE_CONF Used to override the path of make.conf(5) (the default is /etc/make.conf). KERNCONF The name of the kernel configuration file from which the kernel should be built (the default is GENERIC). KERNCONFDIR The directory where the kernel configuration files are kept (the default is /usr/src/sys/config). DESTLABEL Common suffix added to kernel and modules directory names, prefixed by a single dot. For example, make DESTLABEL=test installkernel installs them as /boot/kernel.test and /boot/modules.test, respectively. DESTKERNDIR Where to install the kernel and the modules (the default is /boot), in the directory hierarchy specified by the environment variable DESTDIR. DESTKERNNAME The name of the installed kernel file (the default is kernel), under the directory specified by DESTKERNDIR. This overrides the effect of DESTLABEL. DESTMODULESNAME The name of the directory to install the kernel modules (the default is modules), under the directory specified by DESTKERNDIR. This overrides the effect of DESTLABEL. WORLD_BACKUP Directory for manual backup of binaries of installed world (default: /var/backups/world_backup). AUTO_BACKUP Directory for automatic backup of binaries of installed world (default: MAKEOBJDIRPREFIX/world_binaries/DESTDIR). NO_BACKUP When defined, the automatic backup feature of installworld is inhibited.

FILES

/etc/make.conf /etc/defaults/make.conf /usr/src/share/doc/Makefile /usr/src/Makefile /usr/src/Makefile.inc1 /usr/src/Makefile_upgrade.inc

EXAMPLES

The ``approved'' method of updating your system from the latest sources is: make buildworld make buildkernel KERNCONF=FOO make installkernel KERNCONF=FOO make installworld make upgrade After running these commands a system reboot is required, otherwise many programs which have been rebuilt (such as ps(1), top(1), etc.) may not work with the old kernel which is still running.

CAVEATS

The build and install order in the EXAMPLES section enforces that the new kernel is installed before the new world. Sometimes it might be neces- sary to reboot the system between those two steps. In this case ``make installworld'' will tell you to do so.
