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
     applicable 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
		   using the NO_CPU_CFLAGS and NO_CPU_COPTFLAGS variables,
		   respectively.  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
		   doing 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
		   accepted by the BIOS before booting from disk, making it
		   possible 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
		   option 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.

     LOADER_FIREWIRE_SUPPORT
		   (bool) Defining this and recompiling /usr/src/sys/boot/i386
		   will add dcons(4) console driver to loader(8) and allow
		   access over FireWire(IEEE1394) using dconschat(8).  Cur‐
		   rently, only i386 and amd64 are supported.

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

     NO_CLEAN	   (bool) Set this to disable cleaning during “make
		   buildworld”.	 This should not be set unless you know what
		   you are doing.

     NO_CLEANDIR   (bool) Set this to run “${MAKE} clean” instead of “${MAKE}
		   cleandir”.

     NO_MANCOMPRESS
		   (bool) Set to install manual pages uncompressed.

     NO_SHARE	   (bool) Set to not build in the share subdir.

     NO_SHARED	   (bool) Set to build /bin and /sbin statically linked, this
		   can be bad.	If set, every utility that uses bsd.prog.mk
		   will be linked statically.

     PPP_NO_NAT	   (bool) Build ppp(8) without support for network address
		   translation (NAT).

     PPP_NO_NETGRAPH
		   (bool) Set to build ppp(8) without support for Netgraph.

     PPP_NO_RADIUS
		   (bool) Set to build ppp(8) without support for RADIUS.

     PPP_NO_SUID   (bool) Set to disable the installation of ppp(8) as a set-
		   user-ID root program.

     SENDMAIL_ADDITIONAL_MC
		   (str) Additional .mc files which should be built into .cf
		   files at build time.	 The value should include the full
		   path to the .mc file(s), e.g., /etc/mail/foo.mc
		   /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
		   (str) Override the default location for the m4(1) configu‐
		   ration files used to build a .cf file from a .mc file.

     SENDMAIL_DPADD
		   (str) Extra dependencies to add when building sendmail(8).

     SENDMAIL_LDADD
		   (str) Flags to add to the end of the ld(1) command when
		   building sendmail(8).

     SENDMAIL_LDFLAGS
		   (str) Flags to pass to the ld(1) command when building
		   sendmail(8).

     SENDMAIL_M4_FLAGS
		   (str) Flags passed to m4(1) when building a .cf file from a
		   .mc file.

     SENDMAIL_MAP_PERMS
		   (str) Mode to use when generating alias and map database
		   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
		   maps are always rebuilt if they exist.

     SENDMAIL_MAP_TYPE
		   (str) Database map type to use when generating map database
		   files using /etc/mail/Makefile.  The default value is hash.
		   The alternative is btree.

     SENDMAIL_MC   (str) The default m4(1) configuration file to use at
		   install time.  The value should include the full path to
		   the .mc file, e.g., /etc/mail/myconfig.mc.  Use with cau‐
		   tion 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
		   binary instead of a set-group-ID binary and do not install
		   /etc/mail/submit.{cf,mc}.  Use of this flag is not recom‐
		   mended and the alternative advice in /etc/mail/README
		   should be followed instead if at all possible.

     SENDMAIL_START_SCRIPT
		   (str) The script used by /etc/mail/Makefile to start, stop,
		   and restart sendmail(8).  The default value is
		   /etc/rc.sendmail.  This value should match the
		   “mta_start_script” setting in rc.conf(5).

     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
		   existing /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‐
		   mately twice as large as the number of lines in
		   /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.  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
		    install.

     PRINTERDEVICE  (str) The default format for system documentation, depends
		    on your printer.  This can be set to “ascii” for simple
		    printers, or “ps” for postscript or graphics printers with
		    a ghostscript filter, or both.
