MAKE.CONF(5) BSD File Formats Manual MAKE.CONF(5)NAMEmake.conf — system build information
DESCRIPTION
The file make.conf contains settings that control the compilation of the
DragonFly sources. 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 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 three areas: world, kernel, and documenta‐
tion. Variables set in make.conf may be applicable during builds in one,
two, or all 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 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.
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/defaults/make.conf for a list of
recognized CPUTYPE options.
CCVER (str) Controls which GCC version to use by default. It
should be set as CCVER?= so as not to interfere with over‐
rides from userland. We currently recommend that an over‐
ride NOT be set in /etc/make.conf. Currently accepted val‐
ues for compilers which are part of DragonFly are “gcc41”
and “gcc44” (default). All other values will handled
according to the settings in compilers.conf(5).
BINUTILSVER (str) Controls which binutils to use by default. Currently
accepted values are “binutils220” and “binutils221”
(default).
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}
DEBUG_FLAGS (str) Similar to CFLAGS but it will cause STRIP to be set
to a blank value, if set. Typically, DEBUG_FLAGS is set to
-g for compiling with debug symbols.
NO_CPU_CFLAGS
(str) Setting this variable will prevent CPU specific com‐
piler flags from being automatically added to CFLAGS during
compile time.
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 have components com‐
pared before doing the install, use
INSTALL="install -C"
LOCAL_DIRS (str) List any directories that should be entered when run‐
ning make /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
MODULES_OVERRIDE
(str) Set to a list of modules to build instead of all of
them.
MTREE_FOLLOWS_SYMLINKS
(str) Set this to “-L” to cause mtree(8) to follow sym‐
links.
STRIP (str) Set this to the flag to pass to the strip(1) command.
If set to a blank value, debug symbols will not be removed.
STRIP is automatically set to a blank value if DEBUG_FLAGS
is set.
WANT_HESIOD (bool) Set this to build hesiod(3) support into libc.
NO_NS_CACHING
(bool) Set this to disable name caching in the nsswitch
subsystem. The generic caching daemon, nscd(8), will not
be built either if this option is set.
NO_WERROR Set this if you don't want -Werror to be added to
CWARNFLAGS or used in the kernel build.
STATIC_LOCALES
(str) Set to a list of locales to build into statically-
linked binaries. Currently supported locales are: BIG5 EUC
EUCTW ISO2022 MSKanji UTF8
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.
COPTFLAGS (str) Controls the compiler settings when building the ker‐
nel. Optimization levels above -O (-O2, ...) are not guar‐
anteed to work.
KERNCONF (str) Controls which kernel configurations will be built by
“${MAKE} buildkernel” and installed by “${MAKE}
installkernel”. For example,
KERNCONF=MINE DEBUG GENERIC OTHERMACHINE
will build the kernels specified by the config files MINE,
DEBUG, GENERIC, and OTHERMACHINE, and install the kernel
specified by the config file MINE. It defaults to GENERIC.
LOADER_TFTP_SUPPORT
(bool) While not a buildkernel-affected option, there is no
better place for this. By default the pxeboot(8) loader
retrieves the kernel via NFS. Defining this and recompil‐
ing /usr/src/sys/boot will cause it to retrieve the kernel
via TFTP. This allows pxeboot to load a custom BOOTP disk‐
less kernel yet still mount the server's / rather than load
the server's kernel.
NO_CPU_COPTFLAGS
(str) Setting this variable will prevent CPU specific com‐
piler flags from being automatically added to COPTFLAGS
during compile time.
NO_KERNELCLEAN
(bool) Set this to skip the clean target when using
“${MAKE} buildkernel”.
NO_KERNELCONFIG
(bool) Set this to skip running config(8) during “${MAKE}
buildkernel”.
NO_KERNELDEPEND
(bool) Set this to skip running “${MAKE} depend” during
“${MAKE} buildkernel”.
NO_KERNEL_OLD_STRIP
(bool) Set this to skip stripping debugging symbols from
old kernel and modules (kernel.old, modules.old) during
“${MAKE} installkernel”.
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:
ENABLE_SUID_SSH
(bool) Set this to install ssh(1) with the setuid bit
turned on.
MODULES_WITH_WORLD
(bool) Set to build modules with the system instead of the
kernel.
NO_CRYPT (bool) Set to not build crypto code.
NO_CVS (bool) Set to not build CVS.
NO_GAMES (bool) Set to not build games.
NO_GCC41 (bool) Set to not build the older version of GCC (4.1).
NO_GDB (bool) Set to not build gdb(1)
NO_I4B (bool) Set to not build isdn4bsd package.
NO_IPFILTER (bool) Set to not build IP Filter package.
NO_LIBC_R (bool) Set to not build libc_r (reentrant version of libc).
NO_LPR (bool) Set to not build lpr(1) and related programs.
NO_MAILWRAPPER
(bool) Set to not build the mailwrapper(8) MTA selector.
NO_OBJC (bool) Set to not build Objective C support.
NO_OPENSSH (bool) Set to not build OpenSSH.
NO_OPENSSL (bool) Set to not build OpenSSL (implies NO_OPENSSH).
NO_SENDMAIL (bool) Set to not build sendmail(8) and related programs.
NO_SHARE (bool) Set to not enter the share subdirectory.
NO_X (bool) Set to not compile in X-Windows support (e.g.
doscmd(1)).
NOCLEAN (bool) Set this to disable cleaning during “make
buildworld”. This should not be set unless you know what
you are doing.
NOCLEANDIR (bool) Set this to run “${MAKE} clean” instead of “${MAKE}
cleandir”.
NOFSCHG (bool) Set to not install certain components with flag
schg. This is useful in a jailed environment.
NOINFO (bool) Set to not make or install info(5) files.
NOINFOCOMPRESS
(bool) Set to not compress the info pages.
NOMAN (bool) Set to not build manual pages
NOMANCOMPRESS
(bool) Set to not compress the manual pages.
NOPROFILE (bool) Set to avoid compiling profiled libraries.
PPP_NOSUID (bool) Set to disable the installation of ppp(8) with the
set-user-ID bit on.
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_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.
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.

ration 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

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).

(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 recom‐
mended 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.
THREAD_LIB (str) Set to either c_r or thread_xu to configure the sys‐
