Issuing the make command in any directory or 58subdirectory of those directories has the same effect as issuing the 59same command in all subdirectories of that directory. With no target 60specified, the things in that directory are just built. The following 61list provides the names and actions for other targets: 62.Bl -tag -width Ar 63.It Ar clean 64Removes any files created during the build process. 65.It Ar install 66Installs the results of the build for this directory. 67.It Ar update 68Gets updated sources as configured in 69.Pa /etc/make.conf . 70.El 71.Pp 72The other 73.Pa /usr/src 74make targets are: 75.Bl -tag -width Ar 76.It Ar buildworld 77Rebuild everything but the kernel, configure files in 78.Pa /etc , 79and release. 80.It Ar installworld 81Install everything built by 82.Dq buildworld . 83.It Ar world 84buildworld + installworld. 85.It Ar buildkernel 86Rebuild the kernel and the kernel-modules. 87.It Ar installkernel 88Install the kernel and the kernel-modules. 89.It Ar reinstallkernel 90Reinstall the kernel and the kernel-modules. 91.It Ar upgrade 92Upgrade a.out (2.2.x/3.0) system to the new ELF way 93.It Ar most 94Build user commands, no libraries or include files. 95.It Ar installmost 96Install user commands, no libraries or include files. 97.It Ar aout-to-elf 98Upgrade an system from a.out to elf format. 99.It Ar aout-to-elf-build 100Build everything required to upgrade a system from a.out to elf format. 101.It Ar aout-to-elf-install 102Install everything built by aout-to-elf-build. 103.It Ar move-aout-libs 104Move the a.out libraries into an aout sub-directory of each elf 105library sub-directory. 106.El 107.Pp 108For more information about the ports build process, see 109.Xr ports 7 . 110.Sh FILES 111.Bl -tag -width /etc/defaults/make.conf -compact 112.It Pa /etc/defaults/make.conf 113.It Pa /etc/make.conf 114.It Pa /usr/doc/Makefile 115.It Pa /usr/doc/share/mk/doc.project.mk 116.It Pa /usr/src/Makefile 117.It Pa /usr/src/Makefile.inc1 118.It Pa /usr/ports/Mk/bsd.port.mk 119.It Pa /usr/ports/Mk/bsd.sites.mk 120.Sh EXAMPLES 121The 122.Dq approved 123method of updating your system from the latest sources is: 124.Bd -literal -offset indent 125make buildworld 126make buildkernel KERNEL=FOO 127make installkernel KERNEL=FOO 128make installworld 129mergemaster 130.Ed 131.Pp 132.Dq FOO 133must be replaced with the name of the kernel configuration file from which 134the kernel should be built. 135Alternatively, the 136.Va KERNEL 137variable in 138.Pa /etc/make.conf 139can be set to the name of the kernel to build; 140in this case the 141.Dq KERNEL=FOO 142part of the 143.Dq buildkernel 144and 145.Dq installkernel 146commands can be omitted. 147.Pp 148After running these commands a system reboot is required, 149otherwise many programs which have been rebuilt 150(such as 151.Nm ps , 152.Nm top , 153etc) 154may not work with the old kernel which is still running. 155.Sh SEE ALSO 156.Xr cc 1 , 157.Xr install 1 , 158.Xr make 1 , 159.Xr make.conf 5 , 160.Xr ports 7 , 161.Xr mergemaster 8 , 162.Xr reboot 8 , 163.Xr shutdown 8 164.Sh AUTHORS 165.An Mike W.
