MAKE.CONF(5)		    BSD	File Formats Manual		  MAKE.CONF(5)

NAME
     make.conf -- system build information

DESCRIPTION
     The file make.conf	contains system-wide settings that will	apply to every
     build using make(1) and the standard sys.mk file.	This is	achieved as
     follows: make(1) processes	the system makefile sys.mk before any other
     file by default, and sys.mk includes make.conf.

     The file make.conf	uses the standard makefile syntax.  However, make.conf
     should not	specify	any dependencies to make(1).  Instead, make.conf is to
     set make(1) variables that	control	the actions of other makefiles.

     The default location of make.conf is /etc/make.conf, though an alterna-
     tive location can be specified in the make(1) variable __MAKE_CONF.  You
     may need to override the location of make.conf if the system-wide set-
     tings are not suitable for	a particular build.  For instance, setting
     __MAKE_CONF to /dev/null effectively resets all build controls to their
     defaults.

     The primary purpose of make.conf is to control the	compilation of the
     FreeBSD sources, documentation, and ported	applications, which are	usu-
     ally found	in /usr/src, /usr/doc, and /usr/ports.	As a rule, the system
     administrator creates make.conf when the values of	certain	control	vari-
     ables need	to be changed from their defaults.

     The system	build procedures occur in four broad areas: the	world, the
     kernel, documentation and ports.  Variables set in	make.conf may be ap-
     plicable in one, two, or all four of these	areas.	In addition, control
     variables can be specified	for a particular build via the -D option of
     make(1) or	in environ(7).

     The following lists provide a name	and short description for each vari-
     able you can use during the indicated builds.  The	values of variables
     flagged as	bool are ignored; the variable being set at all	(even to
     "FALSE" or	"NO") causes it	to be treated as if it were set.

     The following list	provides a name	and short description for variables
     that are used for all builds, or are used by the makefiles	for things
     other than	builds.

     ALWAYS_CHECK_MAKE
		   (bool) Instructs the	top-level makefile in the source tree
		   (normally /usr/src) to always check if make(1) is up-to-
		   date.  Normally this	is only	done for the world and build-
		   world targets to handle upgrades from older versions	of
		   FreeBSD.

     CFLAGS	   (str) Controls the compiler setting when compiling C	code.
		   Optimization	levels other than -O and -O2 are not sup-
		   ported.  BDECFLAGS is provided as a set of gcc(1) settings
		   suggested by	Bruce Evans <bde@FreeBSD.org> for developing
		   and testing changes.	 They can be used, if set, by:

			 CFLAGS+=${BDECFLAGS}

     CPUTYPE	   (str) Controls which	processor should be targeted for gen-
		   erated code.	 This controls processor-specific optimiza-
		   tions in certain code (currently only OpenSSL) as well as
		   modifying the value of CFLAGS and COPTFLAGS to contain the
		   appropriate optimization directive to gcc(1).  The auto-
		   matic setting of CFLAGS and COPTFLAGS may be	overridden us-
		   ing the NO_CPU_CFLAGS and NO_CPU_COPTFLAGS variables, re-
		   spectively.	Refer to /usr/share/examples/etc/make.conf for
		   a list of recognized	CPUTYPE	options.

     CVS_UPDATE	   (bool) Set this to use cvs(1) to update your	ports with
		   "make update".

     CXXFLAGS	   (str) Controls the compiler settings	when compiling C++
		   code.  CXXFLAGS is initially	set to the value of CFLAGS.
		   If you want to add to the CXXFLAGS value, use "+=" instead
		   of "=".

     DOCSUPFILE	   (str) The documentation supfile to use when doing a "make
		   update".  This defaults to
		   /usr/share/examples/cvsup/doc-supfile.

     INSTALL	   (str) the default install command.  To install only files
		   for which the target	differs	or does	not exist, use

			 INSTALL="install -C"
		   Note	that some makefiles (including those in	/usr/share/mk)
		   may hardcode	options	for the	supplied install command.

     LOCAL_DIRS	   (str) List any directories that should be entered when do-
		   ing make's in /usr/src in this variable.

     MAKE_SHELL	   (str) Controls the shell used internally by make(1) to
		   process the command scripts in makefiles.  sh(1), ksh(1),
		   and csh(1) all currently supported.

			 MAKE_SHELL?=sh

     MTREE_FOLLOWS_SYMLINKS
		   (str) Set this to "-L" to cause mtree(8) to follow sym-
		   links.

     NO_CPU_CFLAGS
		   (str) Setting this variable will prevent CPU	specific com-
		   piler flags from being automatically	added to CFLAGS	during
		   compile time.

     NO_CPU_COPTFLAGS
		   (str) Setting this variable will prevent CPU	specific com-
		   piler flags from being automatically	added to COPTFLAGS
		   during compile time.

     NO_DOCUPDATE  (bool) Set this to not update the doc tree during "make
		   update".

     NO_PORTSUPDATE
		   (bool) Set this to not update the ports tree	during "make
		   update".

     PORTSSUPFILE  (str) The ports supfile to use when doing a "make update".
		   This	defaults to /usr/share/examples/cvsup/ports-supfile.

     SUP	   (str) The location of the csup(1) or	cvsup(1) command for
		   "make update".

     SUPFILE	   (str) The first supfile to use when doing a "make update".
		   This	defaults to
		   /usr/share/examples/cvsup/standard-supfile.

     SUPFILE1	   (str) The second supfile to use when	doing a	"make update".
		   This	defaults to /usr/share/examples/cvsup/secure-supfile.

     SUPFILE2	   (str) The third supfile to use when doing a "make update".
		   This	defaults to /usr/share/examples/cvsup/secure-supfile.

     SUPFLAGS	   (str) The flag for the sup(1) command when doing "make
		   update".  This defaults to [-g -L 2].

     SUPHOST	   (str) The hostname of the sup server	to use when doing
		   "make update".

     SUP_UPDATE	   (bool) Set this to use cvsup(1) to update your ports	with
		   "make update".

   BUILDING THE	KERNEL
     The following list	provides a name	and short description for variables
     that are only used	doing a	kernel build:

     BOOTWAIT	   (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	ac-
		   cepted by the BIOS before booting from disk,	making it pos-
		   sible to give custom	boot parameters	even when this is set
		   to 0.

     COPTFLAGS	   (str) Controls the compiler settings	when building the ker-
		   nel.	 Optimization levels above [-O (-O2, ...)] are not
		   guaranteed to work.

     KERNCONF	   (str) Controls which	kernel configurations will be built by
		   "${MAKE} buildkernel" and installed by "${MAKE}
		   installkernel".  For	example,

			 KERNCONF=MINE DEBUG GENERIC OTHERMACHINE

		   will	build the kernels specified by the config files	MINE,
		   DEBUG, GENERIC, and OTHERMACHINE, and install the kernel
		   specified by	the config file	MINE.  It defaults to GENERIC.

     MODULES_OVERRIDE
		   (str) Set to	a list of modules to build instead of all of
		   them.

     NO_KERNELCONFIG
		   (bool) Set this to skip running config(8) during "${MAKE}
		   buildkernel".

     NO_KERNELDEPEND
		   (bool) Set this to skip running "${MAKE} depend" during
		   "${MAKE} buildkernel".

     NO_MODULES	   (bool) Set to not build modules with	the kernel.

     PORTS_MODULES
		   Set this to the list	of ports you wish to rebuild every
		   time	the kernel is built.

     WITHOUT_MODULES
		   (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
		   MODULES_OVERRIDE.  This is applied after MODULES_OVERRIDE.

   BUILDING THE	WORLD
     The following list	provides a name	and short description for variables
     that are used during the world build:

     BOOT_COMCONSOLE_PORT
		   (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.

     BOOT_COMCONSOLE_SPEED
		   (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.

     BOOT_PXELDR_ALWAYS_SERIAL
		   (bool) Compile in the code into pxeboot(8) that forces the
		   use of a serial console.  This is analogous to the -h op-
		   tion	in boot(8) blocks.

     BOOT_PXELDR_PROBE_KEYBOARD
		   (bool) Compile in the code into pxeboot(8) that probes the
		   keyboard.  If no keyboard is	found, boot with the dual con-
		   sole	configuration.	This is	analogous to the -D option in
		   boot(8) blocks.

     ENABLE_SUID_K5SU
		   (bool) Set this if you wish to use the ksu utility.	Other-
		   wise, it will be installed without the set-user-ID bit set.

     ENABLE_SUID_NEWGRP
		   (bool) Set this to install newgrp(1)	with the set-user-ID
		   bit set.  Otherwise,	newgrp(1) will not be able to change
		   users' groups.

     ENABLE_SUID_SSH
		   (bool) Set this to install ssh(1) with the set-user-ID bit
		   turned on.

     LOADER_TFTP_SUPPORT
		   (bool) By default the pxeboot(8) loader retrieves the ker-
		   nel via NFS.	 Defining this and recompiling
		   /usr/src/sys/boot will cause	it to retrieve the kernel via
		   TFTP.  This allows pxeboot(8) to load a custom BOOTP	disk-
		   less	kernel yet still mount the server's / rather than load
		   the server's	kernel.

     MAKE_IDEA	   (bool) Set to build the IDEA	encryption code.  This code is
		   patented in the USA and many	European countries.  It	is
		   YOUR	RESPONSIBILITY to determine if you can legally use
		   IDEA.

     NO_DYNAMICROOT
		   (bool) Set this if you do not want to link /bin and /sbin
		   dynamically.

     NO_KERBEROS   (bool) Set this if you do not want to build Kerberos	5 (KTH
		   Heimdal).

     NO_WPA_SUPPLICANT_EAPOL
		   (bool) Build	wpa_supplicant(8) without support for the IEEE
		   802.1X protocol and without support for EAP-PEAP, EAP-TLS,
		   EAP-LEAP, and EAP-TTLS protocols (usable only via 802.1X).

     MODULES_WITH_WORLD
		   (bool) Set to build modules with the	system instead of the
		   kernel.

     NO_BLUETOOTH  (bool) Set to not build Bluetooth related kernel modules,
		   programs and	libraries.

     NO_NETCAT	   (bool) Set to not build nc(1) utility.

     NO_NIS	   (bool) Set to not build NIS(8) support and related pro-
		   grams.  If set, you might need to adopt your
		   nsswitch.conf(5) and	remove `nis' entries.

     NO_NLS_CATALOGS
		   (bool) Set to not build NLS catalog support for csh(1).

     NO_OBJC	   (bool) Set to not build Objective C support.

		   /etc/mail/bar.mc.

     SENDMAIL_ALIASES
		   (str) List of aliases(5) files to rebuild when using
		   /etc/mail/Makefile.	The default value is
		   /etc/mail/aliases.

     SENDMAIL_CFLAGS
		   (str) Flags to pass to the compile command when building
		   sendmail(8).	 The SENDMAIL_*	flags can be used to provide
		   SASL	support	with setting such as:

			 SENDMAIL_CFLAGS=-I/usr/local/include -DSASL
			 SENDMAIL_LDFLAGS=-L/usr/local/lib
			 SENDMAIL_LDADD=-lsasl

     SENDMAIL_CF_DIR

		   files using /etc/mail/Makefile.  The	default	value is 0640.

     SENDMAIL_MAP_SRC
		   (str) Additional maps to rebuild when using
		   /etc/mail/Makefile.	The access, bitdomain, domaintable,
		   genericstable, mailertable, uucpdomain, and virtusertable

		   The alternative is btree.

     SENDMAIL_MC   (str) The default m4(1) configuration file to use at	in-
		   stall time.	The value should include the full path to the
		   .mc file, e.g., /etc/mail/myconfig.mc.  Use with caution as
		   a make install will overwrite any existing
		   /etc/mail/sendmail.cf.  Note	that SENDMAIL_CF is now	depre-
		   cated.

     SENDMAIL_SET_USER_ID
		   (bool) If set, install sendmail(8) as a set-user-ID root

     SENDMAIL_SUBMIT_MC
		   (str) The default m4(1) configuration file for mail submis-
		   sion	to use at install time.	 The value should include the
		   full	path to	the .mc	file, e.g., /etc/mail/mysubmit.mc.
		   Use with caution as a make install will overwrite any ex-
		   isting /etc/mail/submit.cf.

     TOP_TABLE_SIZE
		   (int) top(1)	uses a hash table for the user names.  The
		   size	of this	hash can be tuned to match the number of local
		   users.  The table size should be a prime number approxi-

		   /etc/passwd.	 The default number is 20011.

     WANT_FORCE_OPTIMIZATION_DOWNGRADE
		   (int) Causes	the system compiler to be built	such that it
		   forces high optimization levels to a	lower one.  gcc(1) -O2
		   and above is	known to trigger known optimizer bugs at vari-
		   ous times --	this is	worse on the Alpha platform.  The
		   value assigned is the highest optimization value used.

   BUILDING DOCUMENTATION
     The following list	provides a name	and short description for variables
     that are used when	building documentation.

     DISTDIR	    (str) Where	distfiles are kept.  Normally, this is
		    distfiles in PORTSDIR.

     DOC_LANG	    (str) The list of languages	and encodings to build and in-
		    stall.

     PRINTERDEVICE  (str) The default format for system	documentation, depends
