NAME    [Toc]    [Back]

     make.conf -- system build information

DESCRIPTION    [Toc]    [Back]

     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-todate.
  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 above -O (-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.

     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:

		   libraries.

     COMPAT20	   (bool) Set to install the FreeBSD 2.0 compatibility

     SENDMAIL_MC   (str) The default m4 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 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 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
		   path to the .mc file(s), e.g., /etc/mail/foo.mc
		   /etc/mail/bar.mc.

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

     SENDMAIL_M4_FLAGS
		   (str) Flags passed to m4 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_EXT2FS_MODULE
		   (bool) Set this if you always want to build the Linux
		   ext2fs kernel module when you build modules.

     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.
