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

NAME
     make.conf - system build information

DESCRIPTION
     The file make.conf contains settings that control the compilation of the
     FreeBSD sources and ported applications.  The file make.conf is generally
     created by the system administrator when the values need to be changed
     from their defaults.

     The purpose of make.conf is not to run commands or perform compilation
     actions directly.  Instead, it is included by the various makefiles in
     /usr/src, /usr/ports and /usr/doc which conditionalize their internal
     actions according to the settings found there.

     The /etc/make.conf file is included from the appropriate Makefile which
     specifies the default settings for all the available options.  Options
     need only be specified in /etc/make.conf when the system administrator
     wishes to override these defaults.

     The build procedures occur in four broad areas: the world, the kernel,
     documentations and ports.  Variables set in make.conf may be applicable
     during builds in one, two, or all four of these areas.  They may be
     specified for a particular build via the -D option of make(1).

     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 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
                   buildworld 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
                   supported.  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
                   generated code.  This controls processor-specific
                   optimizations 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 automatic 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.

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

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

     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 ``=''.

     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
                   symlinks.

     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''.

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

     SUP           (str) The location of the cvsup(1) command for ``make
                   update''.

     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''.

     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.

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

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

     The following list provides a name and short description for variables
     that are only used doing a kernel 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.

     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
                   kernel.  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.

     LOADER_TFTP_SUPPORT
                   (bool) While not a buildkernel-affected option, there is no
                   better place for this.  By default the pxeboot(8) loader
                   retrieves the kernel 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 diskless kernel yet still mount the server's / rather
                   than load the server's kernel.

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

     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.

     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.

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

                   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
                   deprecated.

     SENDMAIL_SUBMIT_MC
                   (str) The default m4(1) configuration file for mail
                   submission 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.

     SENDMAIL_ADDITIONAL_MC
                   (str) Additional .mc files which should be built into .cf
                   files at build time.  The value should include the full

                   /etc/mail/bar.mc.

     SENDMAIL_CF_DIR
                   (str) Override the default location for the m4(1)
                   configuration files used to build a .cf file from a .mc
                   file.

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

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

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

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

     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
                   recommended and the alternative advice in /etc/mail/README
                   should be followed instead if at all possible.

     SENDMAIL_MAP_PERMS
                   (str) Mode to use when generating alias and map database
                   files using /etc/mail/Makefile.  The default value is 0640.

     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
                   approximately 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
                   various times -- this is worse on the Alpha platform.  The
                   value assigned is the highest optimization value used.

     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.
