33 .Nd information on how to build the system
37 system and applications are contained in three different directories,
46 sources, which is loosely defined as the things required to rebuild
47 the system to a useful state.
49 contains the source for the system documentation, excluding the manual
52 is a tree that provides a consistent interface for building and
53 installing third party applications.
57 command is used in each of these directories to build and install the
58 things in that directory. Issuing the make command in any directory or
59 subdirectory of those directories has the same effect as issuing the
60 same command in all subdirectories of that directory. With no target
61 specified, the things in that directory are just built. The following
62 list provides the names and actions for other targets:
65 Removes any files created during the build process.
67 Installs the results of the build for this directory.
69 Gets updated sources as configured in
78 Rebuild everything but the kernel, configure files in
82 Install everything built by
85 buildworld + installworld.
87 Rebuild the kernel and the kernel-modules.
89 Install the kernel and the kernel-modules.
90 .It Ar reinstallkernel
91 Reinstall the kernel and the kernel-modules.
93 Upgrade a.out (2.2.x/3.0) system to the new ELF way
95 Build user commands, no libraries or include files.
97 Install user commands, no libraries or include files.
99 Upgrade an system from a.out to elf format.
100 .It Ar aout-to-elf-build
101 Build everything required to upgrade a system from a.out to elf format.
102 .It Ar aout-to-elf-install
103 Install everything built by aout-to-elf-build.
104 .It Ar move-aout-libs
105 Move the a.out libraries into an aout sub-directory of each elf
106 library sub-directory.

150 method of updating your system from the latest sources is:
151 .Bd -literal -offset indent
153 make buildkernel KERNCONF=FOO
154 make installkernel KERNCONF=FOO
160 must be replaced with the name of the kernel configuration file from which
161 the kernel should be built.
166 can be set to the name of the kernel to build;
173 commands can be omitted.
175 After running these commands a system reboot is required,
176 otherwise many programs which have been rebuilt
181 may not work with the old kernel which is still running.
183 The following sequence of commands can be used to cross-build the
184 system for the Alpha architecture on an i386 host:
185 .Bd -literal -offset indent
187 make TARGET_ARCH=alpha buildworld
188 make TARGET_ARCH=alpha DESTDIR=/clients/axp installworld
