MAKE.CONF(5) MidnightBSD 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 alternative 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 settings 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 usually found in /usr/src, /usr/doc, and /usr/ports. As a rule, the system administrator creates make.conf when the values of certain control variables 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 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.

PORTS_MODULES

Set this to the list of ports you wish to rebuild every time the kernel is built.

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:

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
