 .Dt MAKE.CONF 5
 .Os
 .Sh NAME
 .Nm make.conf
 .Nd system build information
 .Sh DESCRIPTION
 The file
 .Nm
 contains system-wide settings that will apply to every build using
 .Xr make 1
 and the standard
 .Pa sys.mk
 file.
 This is achieved as follows:
 .Xr make 1
 processes the system makefile
 .Pa sys.mk
 before any other file by default, and
 .Pa sys.mk
 includes
 .Nm .
 .Pp
 The file
 .Nm
 uses the standard makefile syntax.
 However,
 .Nm
 should not specify any dependencies to
 .Xr make 1 .
 Instead,
 .Nm
 is to set
 .Xr make 1
 variables that control the actions of other makefiles.
 .Pp
 The default location of
 .Nm
 is
 .Pa /etc/make.conf ,
 though an alternative location can be specified in the
 .Xr make 1
 variable
 .Va __MAKE_CONF .
 You may need to override the location of
 .Nm
 if the system-wide settings are not suitable for a particular build.
 For instance, setting
 .Va __MAKE_CONF
 to
 .Pa /dev/null
 effectively resets all build controls to their defaults.
 .Pp
 The primary purpose of
 .Nm
 is to control the compilation of the
 .Fx
 sources, documentation, and ported applications,
 which are usually found in
 .Pa /usr/src ,
 .Pa /usr/doc ,
 and
 .Pa /usr/ports .
 As a rule, the system administrator creates
 .Nm
 when the values of certain control variables need to be changed
 from their defaults.
 .Pp
 The system build procedures occur in four broad areas:
 the world, the kernel, documentation and ports.
 Variables set in
 .Nm
 may be applicable in one, two, or all four of these areas.
 In addition, control variables can be specified
 for a particular build via the
 .Fl D
 option of
 .Xr make 1
 or in
 .Xr environ 7 .
 In the case of world and kernel builds it is possible to put these variables
 into
 .Xr src.conf 5
 instead of
 .Nm .
 This way the environment for documentation and ports builds is not polluted
 by unrelated variables.
 .Pp
 The following lists provide a name and short description for each
 variable you can use during the indicated builds.
 The values of
 variables flagged as
 .Vt bool
 are ignored; the variable being
 set at all (even to
 .Dq Li FALSE
 or
 .Dq Li NO )
 causes it to
 be treated as if it were set.
 .Pp
 The following list provides a name and short description for variables
 that are used for all builds, or are used by the
 .Pa makefiles
 for things other than builds.
 .Bl -tag -width Ar
 .It Va ALWAYS_CHECK_MAKE
 .Pq Vt bool
 Instructs the top-level makefile in the source tree (normally
 .Pa /usr/src )
 to always check if
 .Xr make 1
 is up-to-date.
 Normally this is only done for the world and buildworld targets to handle
 upgrades from older versions of
 .Fx .
 .It Va CFLAGS
 .Pq Vt str
 Controls the compiler setting when compiling C code.
 Optimization levels other than
 .Fl O
 and
 .Fl O2
 are not supported.
 .It Va CPUTYPE
 .Pq Vt str
 Controls which processor should be targeted for generated
 code.
 This controls processor-specific optimizations in
 certain code (currently only OpenSSL) as well as modifying
 the value of
 .Va CFLAGS
 and
 .Va COPTFLAGS
 to contain the appropriate optimization directive to
 .Xr cc 1 .
 The automatic setting of
 .Va CFLAGS
 may be overridden using the
 .Va NO_CPU_CFLAGS
 variable.
 Refer to
 .Pa /usr/share/examples/etc/make.conf
 for a list of recognized
 .Va CPUTYPE
 options.
 .It Va CXXFLAGS
 .Pq Vt str
 Controls the compiler settings when compiling C++ code.
 .Va CXXFLAGS
 is initially set to the value of
 .Va CFLAGS .
 If you want to
 add to the
 .Va CXXFLAGS
 value, use
 .Dq Li +=
 instead of
 .Dq Li = .
 .It Va DTC
 .Pq Vt str
 Select the compiler for DTS (Device Tree Syntax) file.
 .Va DTC
 is initially set to the value of dtc
 .It Va INSTALL
 .Pq Vt str
 the default install command.
 To install only files for which the target differs or does not exist, use
 .Bd -literal -offset indent
 INSTALL+= -C
 .Ed
 Note that some makefiles (including those in
 .Pa /usr/share/mk )
 may hardcode options for the supplied install command.
 .It Va LOCAL_DIRS
 .Pq Vt str
 List any directories that should be entered when doing
 make's in
 .Pa /usr/src
 in this variable.
 .It Va MAKE_SHELL
 .Pq Vt str
 Controls the shell used internally by
 .Xr make 1
 to process the command scripts in makefiles.
 .Xr sh 1 ,
 .Xr ksh 1 ,
 and
 .Xr csh 1
 all currently supported.
 .Pp
 .Dl "MAKE_SHELL?=sh"
 .It Va MTREE_FOLLOWS_SYMLINKS
 .Pq Vt str
 Set this to
 .Dq Fl L
 to cause
 .Xr mtree 8
 to follow symlinks.
 .It Va NO_CPU_CFLAGS
 .Pq Vt str
 Setting this variable will prevent CPU specific compiler flags
 from being automatically added to
 .Va CFLAGS
 during compile time.
 .It Va NO_DOCUPDATE
 .Pq Vt bool
 Set this to not update the doc tree during
 .Dq Li "make update" .
 .It Va NO_PORTSUPDATE
 .Pq Vt bool
 Set this to not update the ports tree during
 .Dq Li "make update" .
 .It Va SVN_UPDATE
 .Pq Vt bool
 Set this to use
 .Xr svn 1
 or
 .Xr svnlite 1
 to update your
 .Pa src
 tree with
 .Dq Li "make update" .
 Note that you can set
 .Va SVN
 to the full path of a
 .Xr svn 1
 binary.
 .El
 .Ss "BUILDING THE KERNEL"
 The following list provides a name and short description for variables
 that are only used doing a kernel build:
 .Bl -tag -width Ar
 .It Va BOOTWAIT
 .Pq Vt int
 Controls the amount of time the kernel waits for a console keypress
 before booting the default kernel.
 The value is approximately milliseconds.
 Keypresses are accepted by the BIOS before booting from disk,
 making it possible to give custom boot parameters even when this is
 set to 0.
 .It Va COPTFLAGS
 .Pq Vt str
 Controls the compiler settings when building the
 kernel.
 Optimization levels above
 .Oo Fl O ( O2 , No ...\& ) Oc
 are not guaranteed to work.
 .It Va KERNCONF
 .Pq Vt str
 Controls which kernel configurations will be
 built by
 .Dq Li "${MAKE} buildkernel"
 and installed by
 .Dq Li "${MAKE} installkernel" .
 For example,
 .Bd -literal -offset indent
 KERNCONF=MINE DEBUG GENERIC OTHERMACHINE
 .Ed
 .Pp
 will build the kernels specified by the config files
 .Pa MINE , DEBUG , GENERIC ,
 and
 .Pa OTHERMACHINE ,
 and install the kernel specified by the config file
 .Pa MINE .
 It defaults to
 .Pa GENERIC .
 .It Va MODULES_OVERRIDE
 .Pq Vt str
 Set to a list of modules to build instead of all of them.
 .It Va NO_KERNELCLEAN
 .Pq Vt bool
 Set this to skip running
 .Dq Li "${MAKE} clean"
 during
 .Dq Li "${MAKE} buildkernel" .
 .It Va NO_KERNELCONFIG
 .Pq Vt bool
 Set this to skip running
 .Xr config 8
 during
 .Dq Li "${MAKE} buildkernel" .
 .It Va NO_KERNELOBJ
 .Pq Vt bool
 Set this to skip running
 .Dq Li "${MAKE} obj"
 during
 .Dq Li "${MAKE} buildkernel" .
 .It Va NO_MODULES
 .Pq Vt bool
 Set to not build modules with the kernel.
 .It Va PORTS_MODULES
 Set this to the list of ports you wish to rebuild every time the kernel
 is built.
 .It Va WITHOUT_MODULES
 .Pq Vt str
 Set to a list of modules to exclude from the build.
 This provides a
 somewhat easier way to exclude modules you are certain you will never
 need than specifying
 .Va MODULES_OVERRIDE .
 This is applied
 .Em after
 .Va MODULES_OVERRIDE .
 .El
 .Ss "BUILDING THE WORLD"
 The following list provides a name and short description for variables
 that are used during the world build:
 .Bl -tag -width Ar
 .It Va BOOT_COMCONSOLE_PORT
 .Pq Vt str
 The port address to use for the console if the boot blocks have
 been configured to use a serial console instead of the keyboard/video card.
 .It Va BOOT_COMCONSOLE_SPEED
 .Pq Vt int
 The baud rate to use for the console if the boot blocks have
 been configured to use a serial console instead of the keyboard/video card.
 .It Va BOOT_PXELDR_ALWAYS_SERIAL
 .Pq Vt bool
 Compile in the code into
 .Xr pxeboot 8
 that forces the use of a serial console.
 This is analogous to the
 .Fl h
 option in
 .Xr boot 8
 blocks.
 .It Va BOOT_PXELDR_PROBE_KEYBOARD
 .Pq Vt bool
 Compile in the code into
 .Xr pxeboot 8
 that probes the keyboard.
 If no keyboard is found, boot with the dual console configuration.
 This is analogous to the
 .Fl D
 option in
 .Xr boot 8
 blocks.
 .It Va ENABLE_SUID_K5SU
 .Pq Vt bool
 Set this if you wish to use the ksu utility.
 Otherwise, it will be
 installed without the set-user-ID bit set.
 .It Va ENABLE_SUID_NEWGRP
 .Pq Vt bool
 Set this to install
 .Xr newgrp 1
 with the set-user-ID bit set.
 Otherwise,
 .Xr newgrp 1
 will not be able to change users' groups.
 .It Va LOADER_TFTP_SUPPORT
 .Pq Vt bool
 By default the
 .Xr pxeboot 8
 loader retrieves the kernel via NFS.
 Defining this and recompiling
 .Pa /usr/src/stand
 will cause it to retrieve the kernel via TFTP.
 This allows
 .Xr pxeboot 8
 to load a custom BOOTP diskless kernel yet
 still mount the server's
 .Pa /
 rather than load the server's kernel.
 .It Va LOADER_FIREWIRE_SUPPORT
 .Pq Vt bool
 Defining this and recompiling
 .Pa /usr/src/stand/i386
 will add
 .Xr dcons 4
 console driver to

 and allow access over FireWire(IEEE1394) using
 .Xr dconschat 8 .
 Currently, only i386 and amd64 are supported.
 .It Va MALLOC_PRODUCTION
 .Pq Vt bool
 Set this to disable assertions and statistics gathering in
 .Xr malloc 3 .
 It also defaults the A and J runtime options to off.
 Disabled by default on -CURRENT.
 .It Va MAN_ARCH
 .Pq Vt str
 Space-delimited list of one or more MACHINE and/or MACHINE_ARCH values
 for which section 4 man pages will be installed.
 The special value
 .Sq all
 installs all available architectures.
 The default is the MACHINE and MACHINE_ARCH being built.
 .It Va MODULES_WITH_WORLD
 .Pq Vt bool
 Set to build modules with the system instead of the kernel.
 .It Va NO_CLEAN
 .Pq Vt bool
 Set this to disable cleaning during
 .Dq Li "make buildworld" .
 This should not be set unless you know what you are doing.
 .It Va NO_CLEANDIR
 .Pq Vt bool
 Set this to run
 .Dq Li "${MAKE} clean"
 instead of
 .Dq Li "${MAKE} cleandir" .
 .It Va WITH_MANCOMPRESS
 .Pq Vt defined
 Set to install manual pages compressed.
 .It Va WITHOUT_MANCOMPRESS
 .Pq Vt defined
 Set to install manual pages uncompressed.
 .It Va NO_SHARE
 .Pq Vt bool
 Set to not build in the
 .Pa share
 subdir.
 .It Va NO_SHARED
 .Pq Vt bool
 Set to build
 .Pa /bin
 and
 .Pa /sbin
 statically linked, this can be bad.
 If set, every utility that uses
 .Pa bsd.prog.mk
 will be linked statically.
 .It Va PPP_NO_NAT
 .Pq Vt bool
 Build
 .Xr ppp 8
 without support for network address translation (NAT).
 .It Va PPP_NO_NETGRAPH
 .Pq Vt bool
 Set to build
 .Xr ppp 8
 without support for Netgraph.

 .Xr ppp 8
 as a set-user-ID root program.
 .It Va SENDMAIL_ADDITIONAL_MC
 .Pq Vt str
 Additional
 .Pa .mc
 files which should be built into
 .Pa .cf
 files at build time.
 The value should include the full path to the
 .Pa .mc

 .Pa /etc/mail/foo.mc ,
 .Pa /etc/mail/bar.mc .
 .It Va SENDMAIL_ALIASES
 .Pq Vt str
 List of
 .Xr aliases 5
 files to rebuild when using
 .Pa /etc/mail/Makefile .
 The default value is
 .Pa /etc/mail/aliases .
 .It Va SENDMAIL_CFLAGS
 .Pq Vt str
 Flags to pass to the compile command when building
 .Xr sendmail 8 .
 The
 .Va SENDMAIL_*
 flags can be used to provide SASL support with setting such as:
 .Bd -literal -offset indent
 SENDMAIL_CFLAGS=-I/usr/local/include -DSASL
 SENDMAIL_LDFLAGS=-L/usr/local/lib
 SENDMAIL_LDADD=-lsasl
 .Ed
 .It Va SENDMAIL_CF_DIR
