MK.CONF(5)

NAME
mk.conf - make configuration file

DESCRIPTION
The mk.conf file overrides various parameters used during the build of the system.

Listed below are the mk.conf variables that may be set, the values to which each may be set, a brief description of what each variable does, and a reference to relevant manual pages.

  NetBSD System variables

NETBSDSRCDIR
    The path to the top level of the NetBSD sources. If make(1) is run from within the NetBSD source tree, the default is the top level of that tree (as determined by the presence of build.sh and tools/), otherwise BSDSRCDIR will be used.

BSDOBJDIR
    The real path to the ‘obj’ tree for the NetBSD source tree. /usr/obj

BSDSRCDIR
    The real path to the NetBSD source tree. /usr/src

BUILD
    If defined, ‘make install’ checks that the targets in the source directories are up-to-date and re-makes them if they are out of date, instead of blindly trying to install out of date or non-existent targets.

BUILDID
    Identifier for the build. The identifier will be appended to object directory names, and can be consulted in the make(1) configuration file in order to set additional build parameters, such as compiler flags.

COPTS
    Extra options for the C compiler. Should be appended to (e.g., COPTS+=-g), rather than explicitly set.

DESTDIR
    Directory to contain the built NetBSD system. If set, special options are passed to the compilation tools to prevent their default use of the host system's /usr/include, /usr/lib, and so forth. This pathname should not end with a slash (/) character (for installation into the system's root directory, set DESTDIR to an empty string). The directory must reside on a file system which supports long file names and hard links. Empty string if USETOOLS is “yes”; unset otherwise.

    Note: build.sh will provide a default of destdir.MACHINE (in the top-level .OBJDIR) unless run in ‘expert’ mode

MKBFD
    Indicates whether libbfd, libiberty, or any of the things that depend upon them (such as the binutils, as(1), gdb(1), ld(1), dbsym(8), or mdsetimage(8)) should be built.

MKCATPAGES
    Indicates whether preformatted plaintext manual pages will be created during a build.

MKCRYPTO
    Indicates whether cryptographic code will be included in a build; provided for the benefit of countries that do not allow strong cryptography. Will not affect use of the standard low-security password encryption system, crypt(3).

    If “no”, acts as MKKERBEROS=no.

MKCRYPTO_IDEA
    Indicates whether IDEA support will be built into libcrypto_idea.a.

MKCRYPTO_MDC2
    Indicates whether MDC2 support will be built into libcrypto_mdc2.a.

MKCRYPTO_RC5
    Indicates whether RC5 support will be built into libcrypto_rc5.a.

MKCVS
    Indicates whether cvs(1) is built.

MKDEBUG
    Indicates whether separate debugging symbols should be installed into DESTDIR/usr/libdata/debug.

MKDEBUGLIB
    Indicates whether debug libraries (lib*_g.a) will be built and installed during a build. Debug libraries are compiled with “-g -DDEBUG”.

MKDOC
    Indicates whether system documentation destined for DESTDIR/usr/share/doc will be installed during a build.

MKDYNAMICROOT
    Indicates whether all programs should be dynamically linked, and to install shared libraries required by /bin and /sbin and the shared linker ld.elf_so(1) into /lib. If ‘no’, link programs in /bin and /sbin statically.

MKGCC
    Indicates whether gcc(1) or any related libraries (libg2c, libgcc, libobjc, libstdc+) are built.

MKGDB
    Indicates whether gdb(1) is built.

MKHESIOD
    Indicates whether the Hesiod infrastructure (libraries and support programs) is built.

MKHOSTOBJ
    If set to “yes”, then for programs intended to be run on the compile host, the name, release, and architecture of the host operating system will be suffixed to the name of the object directory created by “make obj”. (This allows multiple host systems to compile NetBSD for a single target.) If set to “no”, then programs built to be run on the compile host will use the same object directory names as programs built to be run on the target.

MKHTML
    Indicates whether the html manual pages are built and installed.

MKIEEEFP
    Indicates whether code for IEEE754/IEC60559 conformance is built. Has no effect on most platforms.

MKINFO
    Indicates whether GNU Info files, used for the documentation for most of the compilation tools, will be created and installed during a build.

MKIPFILTER
    Indicates whether the ipf(4) programs, headers and LKM will be compiled and installed during a build.

MKKERBEROS
    Indicates whether the Kerberos v5 infrastructure (libraries and support programs) is built.

MKLINKLIB
    Indicates whether all of the shared library infrastructure is built. If ‘no’, prevents: installation of the *.a libraries, installation of the *_pic.a libraries on PIC systems, building of *.a libraries on PIC systems, or installation of .so symlinks on ELF systems.

    If “no”, acts as MKPICINSTALL=no MKPROFILE=no.

MKLINT
    Indicates whether lint(1) will be run against portions of the NetBSD source code during the build, and whether lint libraries will be installed into DESTDIR/usr/libdata/lint.

MKMAN
    Indicates whether manual pages will be installed during a build.

    If “no”, acts as MKCATPAGES=no MKHTML=no.

MKMANZ
    Indicates whether manual pages should be compressed with gzip(1) at installation time.

MKNLS
    Indicates whether Native Language System (NLS) locale zone files will be compiled and installed during a build.

MKOBJ
    Indicates whether object directories will be created when running “make obj”. If set to “no”, then all built files will be located inside the regular source tree.

    If “no”, acts as MKOBJDIRS=no.

MKOBJDIRS
    Indicates whether object directories will be created automatically (via a “make obj” pass) at the start of a build.

MKPAM
    Indicates whether the pam(8) framework (libraries and support files) is built. The pre-PAM code is not supported and may be removed in the future.

MKPF
    Indicates whether the pf(4) programs, headers and LKM will be compiled and installed during a build.

MKPIC
    Indicates whether shared objects and libraries will be created and installed during a build. If set to “no”, the entire built system will be statically linked. Platform dependent. As of this writing, all platforms except m68000 and sh3 default to “yes”.

    If “no”, acts as MKPICLIB=no.

MKPICINSTALL
    Indicates whether the ar(1) format libraries (lib*_pic.a), used to generate shared libraries, are installed during a build.

MKPICLIB
    Indicates whether the ar(1) format libraries (lib*_pic.a), used to generate shared libraries.

MKPOSTFIX
    Indicates whether Postfix is built.

MKPROFILE
    Indicates whether profiled libraries (lib*_p.a) will be built and installed during a build. “yes”; however, some platforms turn off MKPROFILE by default at times due to toolchain problems with profiled code.

MKSHARE
    Indicates whether files destined to reside in DESTDIR/usr/share will be built and installed during a build.

    If “no”, acts as MKCATPAGES=no MKDOC=no MKINFO=no MKHTML=no MKMAN=no MKNLS=no.

MKSKEY
    Indicates whether the S/key infrastructure (libraries and support programs) is built.

MKSOFTFLOAT
    Indicates whether the compiler generates output containing library calls for floating point and possibly soft-float library support.

MKUNPRIVED
    Indicates whether an unprivileged install will occur. The user, group, permissions, and file flags, will not be set on the installed item; instead the information will be appended to a file called METALOG in DESTDIR. The contents of METALOG is used during the generation of the distribution tar files to ensure that the appropriate file ownership is stored.

MKUPDATE
    Indicates whether all install operations intended to write to DESTDIR will compare file timestamps before installing, and skip the install phase if the destination files are up-to-date. This also has implications on full builds (see next subsection).

MKUUCP
    Indicates whether uucp(1) and related programs are built.

MKYP
    Indicates whether the YP (NIS) infrastructure (libraries and support programs) is built.

OBJMACHINE
    If defined, creates objdirs of the form obj.MACHINE, where MACHINE is the current architecture (as per ‘uname -m’).

RELEASEDIR
    If set, specifies the directory to which a release(7) layout will be written at the end of a “make release”.

    Note: build.sh will provide a default of releasedir (in the top-level .OBJDIR) unless run in ‘expert’ mode

TOOLDIR
    Directory to hold the host tools, once built. This directory should be unique to a given host system and NetBSD source tree. (However, multiple targets may share the same TOOLDIR; the target-dependent files have unique names.) If unset, a default based on the uname(1) information of the host platform will be created in the .OBJDIR of src.

USETOOLS
    Indicates whether the tools specified by TOOLDIR should be used as part of a build in progress. Must be set to “yes” if cross-compiling.

    yes Use the tools from TOOLDIR.

    no  Do not use the tools from TOOLDIR, but refuse to build native compilation tool components that are version-specific for that tool.

    never
        Do not use the tools from TOOLDIR, even when building native tool components. This is similar to the traditional NetBSD build method, but does not verify that the compilation tools in use are up-to-date enough in order to build the tree successfully. This may cause build or runtime problems when building the whole NetBSD source tree.
    “yes” if building all or part of a whole NetBSD source tree (detected automatically); “no” otherwise (to preserve traditional semantics of the <bsd.*.mk> make(1) include files).
