MK.CONF(5)

NAME
mk.conf - system-specific configuration parameters

SYNOPSIS
.include <bsd.own.mk>

DESCRIPTION
To get system-specific configuration parameters, <bsd.own.mk> will try to include the file specified by the MAKECONF variable. If MAKECONF is not set, or no such file exists, the system make configuration file /etc/mk.conf is included, if it exists. By default, this file does not exist, and must be created from scratch. For more information on how the make process works, and details of the format of make files, see make(1).

<bsd.own.mk> is generally useful when building Makefiles, so that they use the same default owners, etc. as the rest of the tree. These files may define any of the variables described below. Additionally, see bsd.port.mk(5) for a list of variables that can be set by the ports(7) subsystem.

VARIABLES
The following variables are set by <bsd.own.mk>, if they are not already defined. Defaults are in brackets.

BINGRP
    Binary group. [bin]

BINMODE
    Binary mode. [555]

BINOWN
    Binary owner. [root]

BSDOBJDIR
    The real path to the system "obj" tree, so that "make obj" will work correctly. [/usr/obj]

BSDSRCDIR
    The real path to the system sources, so that "make obj" will work correctly. [/usr/src]

DIRMODE
    Mode for new directories. [755]

DOCDIR
    Base path for system documentation installation. [/usr/share/doc]

DOCGRP
    Documentation group. [bin]

DOCMODE
    Documentation mode. [${NONBINMODE}]

DOCOWN
    Documentation owner. [root]

INSTALL_COPY
    The old usage of this flag is obsolescent, since install(1) now copies by default. However, it can also be used to specify that a file not be copied unless it is different (via the -p option). See install(1) for details. This is to be used when building an install script so that the entire system can either be installed with copies, or copy-if-different using a single knob. [-c]

INSTALL_STRIP
    The flag passed to the install program to cause the binary to be stripped. This is to be used when building an install script so that the entire system can be made stripped/not-stripped using a single knob. Note that INSTALL_STRIP is not set if ${DEBUG} is defined. [-s]

LIBDIR
    Base path for library installation. [/usr/lib]

LIBGRP
    Library group. [${BINGRP}]

LIBMODE
    Library mode. [${NONBINMODE}]

LIBOWN
    Library owner. [${BINOWN}]

MANDIR
    Base path for manual installation. [/usr/share/man/man]

MANGRP
    Manual group. [bin]

MANMODE
    Manual mode. [${NONBINMODE}]

MANOWN
    Manual owner. [root]

NONBINMODE
    Mode for non-executable files. [444]

XOBJDIR
    The real path to the "obj" tree for building the X Window System. [/usr/xobj]

XSRCDIR
    The real path to the X Window System sources. [/usr/xenocara]

ADDITIONAL VARIABLES
Additionally, the following variables may be set by <bsd.own.mk> or in a make configuration file to modify the behaviour of the system build process (default values are in brackets along with comments, if set by <bsd.own.mk>):

BUILDUSER
    De-escalate privileges to user BUILDUSER when building the base system from source or making release tarballs. [build]

DEBUG
    Added to assembly, C compiler and linking passes. Typically set to -g to build with debugging symbols. Also doesn't set INSTALL_STRIP to -s per default if defined.

GLOBAL_AUTOCONF_CACHE
    Set to the name of a file that all cached GNU autoconf test results will be saved in. Reduces redundant tests. Be careful! Redundant tests may not be redundant when installing substantially updated GNU programs.

KEEPKERNELS
    If set to "yes", the kernel object directories will not be cleaned out during "make build".

NOPIC
    Do not build shared libraries.

NOPIE
    Do not build PIE objects or executables.

NOPROFILE
    Do not build profiled versions of system libraries.

PIPE
    If set to "-pipe", gcc(1) will be given the -pipe option which can speed up compiles on machines with memory to spare. Instead of using temp files, gcc(1) uses pipes for the temporary data.

SKEY
    Compile in support for S/key authentication. [yes; set unconditionally]

SKIPDIR
    A space separated list of directories, relative to BSDSRCDIR, to be skipped during "make build".

SUDO
    Command run by make(1) when doing certain operations requiring root privileges.

SYS_INCLUDE
    Copy or symlink kernel include files into /usr/include. Possible values are "symlinks" or "copies" (which is the same as the variable being unset).

WARNINGS
    Adds appropriate warning flags (defined in CDIAGFLAGS, e.g. -Wall...) to compiles. [no]

WOBJGROUP
    Group having write access to BSDOBJDIR and XOBJDIR. [wobj]

WOBJUMASK
    umask(2) with which the "obj" tree will be created by "make obj". [007]

XENOCARA_BUILD_DRI
    Build X with Direct Rendering Infrastructure (DRI) support, providing some hardware acceleration. This is on by default for amd64/i386 architectures.

XENOCARA_RERUN_AUTOCONF
    Forces X builds to re-run automake and autoconf in each module before configuring them. This option requires that the automake, autoconf and libtool packages are installed. [no]

FILES
/etc/mk.conf
    System make configuration file.
/usr/share/mk/*
    System include make files.
