make.conf -- system build information
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 <[email protected]> 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:

KRB5_HOME (str) If you want to install the MIT Kerberos5 port somewhere
other than /usr/local, define this. This is also
used to tell ssh1 that Kerberos is needed.
MAKE_IDEA (bool) Set to build the IDEA encryption code. This code is
patented in the USA and many European countries. It is

it will be installed without the set-user-ID bit set.
ENABLE_SUID_NEWGRP

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.

.mc file.
SENDMAIL_CFLAGS

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

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.
