MAKE.CONF(5) FreeBSD 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 <bdeATFreeBSD.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.

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.

includes rlogin(1), rsh(1), etc.

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_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.

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

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_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 -- 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
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.
