NAME
mk.conf -- make configuration file
DESCRIPTION
The mk.conf file overrides various parameters used during the build of the system.
NETBSD SYSTEM VARIABLES
Listed below are the mk.conf variables that may be set that affect the NetBSD system build, the values to which each may be set, a brief description of what each variable does, references to relevant manual pages, notes (including any interaction with build.sh), and the default value of each variable. BSDOBJDIR The real path to the object directory tree for the NetBSD source tree. Default: ``/usr/obj''. BSDSRCDIR The real path to the NetBSD source tree, if NETBSDSRCDIR isn't defined. Default: ``/usr/src''. BUILD If defined, `make install' checks that the make(1) targets in the source directories are up-to-date and re- makes them if they are out of date, instead of blindly trying to install out of date or non-existent make(1) targets. Default: Unset. BUILDID Identifier for the build. If set, this should be a short string that is suitable for use as part of a file or directory name. The identifier will be appended to object directory names; if OBJMACHINE is also set, then .BUILDID is appended after .MACHINE. The identifier will also be used as part of the kernel version string, which can be shown by ``uname -v''. Default: Unset. BUILDINFO Optional multi-line string containing information about the build. This will appear in DESTDIR/etc/release, and it will be stored in the buildinfo variable in any kernels that are built. When such kernels are booted, the sysctl(7) kern.buildinfo variable will report this value. The string may contain backslash escape sequences, such as ``\\'' (representing a backslash character) and ``\n'' (representing a newline). Default: Unset. BUILDSEED g++(1) uses random numbers when compiling C++ code. This variable seeds the g++(1) random number generator using -frandom-seed with this value. By default, it is set to ``NetBSD-(majorversion)''. Using a fixed value causes C++ binaries to be the same when built from the same sources, resulting in identical (reproducible) builds. Additional information is available in the g++(1) documentation of -frandom-seed. Default: Unset. CDEXTRA A space-separated list of files or directories that will be added to the CD-ROM image that may be create by the build.sh ``iso-image'' or ``iso-image-source'' operations. Files will be added to the root of the CD- ROM image, whereas directories will be copied recursively. If relative paths are specified, they will be converted to absolute paths before being used. Note: If using build.sh, multiple paths may be specified via multiple -C options, or via a single option whose argument contains multiple space-separated paths. Default: Unset. CONFIGOPTS Additional options to config(1) when building kernels. Default: Unset. COPTS Extra options for the C compiler. Should be appended to (e.g., COPTS+=-g), rather than explicitly set. Note: CPUFLAGS, not COPTS, should be used for compiler options that select CPU-related options. Note: CFLAGS should never be set in mk.conf. CPUFLAGS Additional options passed to the compiler/assembler to select CPU instruction set options, CPU tuning options, etc. Note: Such options should not be specified in COPTS, because some parts of the build process need to override CPU-related compiler options. Default: Unset. 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 must be an absolute path, and should not end with a slash (/) character. (For installation into the system's root directory, set DESTDIR to an empty string, not to ``/''). The directory must reside on a file system which supports long file names and hard links. Note: build.sh will provide a default of ``destdir.MACHINE'' (in the top-level .OBJDIR) unless run in `expert' mode with the -E option. Default: Empty string if USETOOLS=yes; otherwise unset. EXTERNAL_TOOLCHAIN If defined, this variable indicates the root directory of an external toolchain which will be used to build the tree. For example, if a platform is a TOOLCHAIN_MISSING platform, EXTERNAL_TOOLCHAIN can be used to re-enable the cross-compile framework. If EXTERNAL_TOOLCHAIN is defined, act as MKGCC=no, since the external version of the compiler may not be able to build the library components of the in-tree compiler. This variable should be used in conjunction with an appropriate HAVE_GCC or HAVE_LLVM setting to control the compiler options. Note: This variable is not yet used in as many places as it should be. Expect the exact semantics of this variable to change in the short term as parts of the cross-compile framework continue to be cleaned up. Default: Unset. INSTALLBOOT_BOARDS A list of evbarm boards to create bootable images for. If corresponding U-Boot packages are installed, bootable images are created as part of a release. See the -o board=name option of installboot(8). Default: Unset. INSTALLWORLDDIR Directory for the top-level make(1) ``installworld'' target to install to. If specified, must be an absolute path. Default: ``/''. KERNARCHDIR Directory under KERNSRCDIR containing the machine dependent kernel sources. Default: ``arch/MACHINE''. KERNCONFDIR Directory containing the kernel configuration files. Default: ``KERNSRCDIR/KERNARCHDIR/conf''. KERNEL_DIR (experimental) Can be set to ``yes'' or ``no''. Indicates if a top- level directory /netbsd/ is created. If ``yes'', the directory will contain a kernel file /netbsd/kernel and a corresponding modules directory /netbsd/modules/. System bootstrap procedures will be modified to search for the kernel and modules in the /netbsd/ directory. This is intended to simplify system upgrade and rollback procedures by keeping the kernel and its associated modules together in one place. If ``no'', the kernel file will be stored in /netbsd and the modules will be stored within the /stand/${ARCH}/ directory hierarchy. The KERNEL_DIR option is a work-in-progress, and is highly experimental. It is also subject to change without notice. Default: ``no''. KERNOBJDIR Directory for kernel builds. For example, the kernel GENERIC will be compiled in KERNOBJDIR/GENERIC. Default: ``MAKEOBJDIRPREFIX/KERNSRCDIR/KERNARCHDIR/compile'' if it exists or the make(1) ``obj'' target is being made; otherwise ``KERNSRCDIR/KERNARCHDIR/compile''. KERNSRCDIR Directory at the top of the kernel source. Default: ``NETBSDSRCDIR/sys''. LOCALTIME The name of the tzfile(5) timezone file in the directory /usr/share/zoneinfo to symbolically link DESTDIR/etc/localtime to. Default: ``UTC''. MAKEVERBOSE Level of verbosity of status messages. Supported values: 0 No descriptive messages or commands executed by make(1) are shown. 1 Brief messages are shown describing what is being done, but the actual commands executed by make(1) are not shown. 2 Descriptive messages are shown as above (prefixed with a `#'), and ordinary commands performed by make(1) are shown. 3 In addition to the above, all commands performed by make(1) are shown, even if they would ordinarily have been hidden through use of the ``@'' prefix in the relevant makefile. 4 In addition to the above, commands executed by make(1) are traced through use of the sh(1) ``-x'' flag. Default: 2. MKAMDGPUFIRMWARE Can be set to ``yes'' or ``no''. Indicates whether to install the /libdata/firmware/amdgpu directory, which is necessary for the amdgpu(4) AMD RADEON GPU video driver.

Indicates whether the normal static libraries (lib*_g.a) will be built and installed. Forced to ``no'' if NOSTATICLIB is defined, usually in the Makefile before any make(1) .include directives. Default: ``yes''. MKSTATICPIE Can be set to ``yes'' or ``no''. Indicates whether support for static PIE binaries will be built and installed. These binaries use a special support in crt0.o for resolving relative relocations and require linker support. Default: ``yes'' on i386 and x86_64; ``no'' on other platforms. MKSTRIPIDENT Can be set to ``yes'' or ``no''. Indicates whether RCS IDs, for use with ident(1), should be stripped from program binaries and shared libraries. Default: ``no''. MKSTRIPSYM Can be set to ``yes'' or ``no''. Indicates whether all local symbols should be stripped from shared libraries. If ``yes'', strip all local symbols from shared libraries; the effect is equivalent to the -x option of ld(1). If ``no'', strip only temporary local symbols; the effect is equivalent to the -X option of ld(1). Keeping non-temporary local symbols such as static function names is useful on using DTrace for userland libraries and getting a backtrace from a rumpkernel(7) kernel loading shared libraries. Forced to ``no'' if MKDEBUG=yes. Default: ``yes''. MKTEGRAFIRMWARE Can be set to ``yes'' or ``no''. Indicates whether to install the /libdata/firmware/nvidia directory, which is necessary for the NVIDIA Tegra XHCI driver. Default: ``yes'' on evbarm; ``no'' on other platforms. MKTPM Can be set to ``yes'' or ``no''. Indicates whether to install the Trusted Platform Module (TPM) infrastructure. Default: ``no''. MKUNBOUND Can be set to ``yes'' or ``no''. Indicates whether the unbound(8) DNS resolver will be built and installed. Default: ``yes''. MKUNPRIVED Can be set to ``yes'' or ``no''. Indicates whether an unprivileged install will occur. The user, group, permissions, and file flags, will not be set on the installed items; instead the information will be appended to a file called METALOG in DESTDIR. The METALOG contents are used during the generation of the distribution tar files to ensure that the appropriate file ownership is stored. This allows a non-root `make install'. Default: ``no''. MKUPDATE Can be set to ``yes'' or ``no''. 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. For top-level builds this this implies the effects of NOCLEANDIR (i.e., ``make cleandir'' is avoided). Note: This may be set to ``yes'' by giving build.sh the -u option. Default: ``no''. MKX11 Can be set to ``yes'' or ``no''. Indicates whether X11 will be built and installed from X11SRCDIR, and whether the X sets will be created. Note: If ``yes'', requires MKINET6=yes. Default: ``no''. MKX11FONTS Can be set to ``yes'' or ``no''. If ``no'', do not build and install the X fonts. The xfont set is still created but will be empty. Only used if MKX11=yes. Default: ``yes''. MKX11MOTIF Can be set to ``yes'' or ``no''. If ``yes'', build the native Xorg libGLw with Motif stubs. Requires that Motif can be found via X11MOTIFPATH. Default: ``no''. MKXORG_SERVER Can be set to ``yes'' or ``no''. Indicates whether the Xorg(7) X server and drivers will be built and installed. Default: ``yes'' on alpha, amd64, amiga, bebox, cats, dreamcast, ews4800mips, evbarm, evbmips, evbppc, hp300, hpcarm, hpcmips, hpcsh, hppa, i386, ibmnws, iyonix, luna68k, mac68k, macppc, netwinder, newsmips, pmax, prep, ofppc, sgimips, shark, sparc, sparc64, vax, and zaurus; ``no'' on other platforms. MKYP Can be set to ``yes'' or ``no''. Indicates whether the YP (NIS) infrastructure (libraries and support programs) will be built and installed. Default: ``yes''. MKZFS Can be set to ``yes'' or ``no''. Indicates whether the ZFS kernel module and the utilities and libraries used to manage the ZFS system are to be built and installed. Note: ZFS requires 64-bit atomic operations. Default: ``yes'' on aarch64, amd64, and sparc64; ``no'' on other platforms. NETBSDSRCDIR The path to the top level of the NetBSD sources. Default: Top level of the NetBSD source tree (as determined by the presence of build.sh and tools/) if make(1) is run from within that tree; otherwise BSDSRCDIR will be used. NETBSD_OFFICIAL_RELEASE Can be set to ``yes'' or ``no''. Indicates whether the build creates an official NetBSD release which is going to be available from ftp.NetBSD.org and/or cdn.NetBSD.org locations. This variable modifies a few default paths in the installer and also creates different links in the install documentation. The auto-build cluster uses this variable to distinguish `daily' builds from real releases. Default: Unset. (I.e., ``no''). NETBSD_REVISIONID Tree-wide revision identifier, such as a Mercurial or Git commit hash or similar. If set, will be included in program notes where __RCSID(3) and __KERNEL_RCSID(3) are used, and will be reported by ident(1). Default: Unset. NOCLEANDIR If set, avoids the ``make cleandir'' phase of a full build. This has the effect of allowing only changed files in a source tree to be recompiled. This can speed up builds when updating only a few files in the tree. See also MKUPDATE. Default: Unset. NODISTRIBDIRS If set, avoids the ``make distrib-dirs'' phase of a full build. This skips running mtree(8) on DESTDIR, useful on systems where building as an unprivileged user, or where it is known that the system-wide mtree(8) files have not changed. Default: Unset. NOINCLUDES If set, avoids the ``make includes'' phase of a full build. This has the effect of preventing make(1) from thinking that some programs are out-of-date simply because the system include files have changed. However, this option should not be used when updating the entire NetBSD source tree arbitrarily; it is suggested to use MKUPDATE=yes instead in that case. Default: Unset. OBJMACHINE If defined, creates objdirs of the form obj.MACHINE, where MACHINE is the current architecture (as per `uname -m'). Default: Unset. RELEASEDIR If set, specifies the directory to which a release(7) layout will be written at the end of a ``make release''. If specified, must be an absolute path. Note: build.sh will provide a default of ``releasedir'' (in the top-level .OBJDIR) unless run in `expert' mode with the -E option. Default: Unset. RUMPUSER_THREADS Defines the threading implementation used by the rumpuser(3) hypercall implementation. Supported values: fiber Use a fiber interface, with cooperatively scheduled contexts. none Do not support kernel threads. pthread Use pthread(3) to implement threads. Default: ``pthread''. RUMP_CURLWP Defines how curlwp is obtained in the rumpkernel(7) kernel. curlwp is a very frequently accessed thread- local variable, and optimizing access has a significant performance impact. Note that all options are not available on hosts/machine architectures. Supported values: hypercall Use a hypercall to fetch the value. register Use a dedicated register. (Implies compiling with -ffixed-reg). __thread Use the __thread feature to fetch value via thread local storage (TLS). Default: ``hypercall''. RUMP_DEBUG If defined, indicates whether rumpkernel(7) kernels are built with -DDEBUG. Default: Unset. RUMP_DIAGNOSTIC Can be set to ``yes'' or ``no''. Indicates whether rumpkernel(7) kernels are built with -DDIAGNOSTIC. Default: ``yes''. RUMP_KTRACE Can be set to ``yes'' or ``no''. Indicates whether rumpkernel(7) kernels are built with -DKTRACE. Default: ``yes''. RUMP_LOCKDEBUG If defined, indicates whether rumpkernel(7) kernels are built with -DLOCKDEBUG. Default: Unset. RUMP_LOCKS_UP Can be set to ``yes'' or ``no''. Indicates whether rumpkernel(7) kernels are built with uniprocess-optimized locking or not. If ``yes'', build with uniprocess-optimized locking, which requires RUMP_NCPU=1 in the environment at runtime. If ``no'', build with multiprocessor-capable locking. Default: ``no''. RUMP_NBCOMPAT Selects which NetBSD userland binary compatibility COMPAT_ver kernel options are enabled in the rumpkernel(7) kernels. This option is useful only when building rumpkernel(7) kernels for NetBSD userspace, and an empty value may be supplied elsewhere. Supported (one or more, comma-separated) values: all All supported release versions. Equivalent to ``50,60,70,80,90''. default Default value. Equivalent to ``all'', although this default may change in the future. none No compatibility options are enabled. 50 NetBSD 5.x compatibility, via COMPAT_50 kernel option. 60 NetBSD 6.x compatibility, via COMPAT_60 kernel option. 70 NetBSD 7.x compatibility, via COMPAT_70 kernel option. 80 NetBSD 8.x compatibility, via COMPAT_80 kernel option. 90 NetBSD 9.x compatibility, via COMPAT_90 kernel option. Default: ``all''. RUMP_VIRTIF Can be set to ``yes'' or ``no''. Indicates whether rumpkernel(7) kernels are built with support for the virt(4) network interface. If ``no'', don't build with virt(4) support, which may be necessary on systems that lack the necessary headers, such as musl libc based Linux. Default: ``yes''. RUMP_VNODE_LOCKDEBUG If defined, indicates whether rumpkernel(7) kernels are built with -DVNODE_LOCKDEBUG. Default: Unset. TOOLCHAIN_MISSING Can be set to ``yes'' or ``no''. If not ``no'', this indicates that the platform ``MACHINE_ARCH'' being built does not have a working in-tree toolchain. If not ``no'', acts as MKBINUTILS=no MKGCC=no MKGDB=no. Default: ``no''. TOOLDIR Directory to hold the host tools, once built. If specified, must be an absolute path. This directory should be unique to a given host system and NetBSD source tree. (However, multiple target architectures may share the same TOOLDIR; the target-architecture-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. Default: Unset. USETOOLS Can be set to ``yes'' or ``no''. 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. Supported values: 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. Default: ``no'' when using <bsd.*.mk> outside the NetBSD source tree (detected automatically) or if TOOLCHAIN_MISSING=yes; otherwise ``yes''. USE_FORT Can be set to ``yes'' or ``no''. Indicates whether the so-called ``FORTIFY_SOURCE'' security(7) extensions are enabled; see ssp(3) for details. This imposes some performance penalty. Forced to ``no'' if NOFORT is defined, usually in the Makefile before any make(1) .include directives. Default: ``no''. USE_HESIOD Can be set to ``yes'' or ``no''. Indicates whether Hesiod support is enabled in the various applications that support it. Forced to ``no'' if MKHESIOD=no. Default: ``yes''. USE_INET6 Can be set to ``yes'' or ``no''. Indicates whether INET6 (IPv6) support is enabled in the various applications that support it. Forced to ``no'' if MKINET6=no. Default: ``yes''. USE_JEMALLOC Can be set to ``yes'' or ``no''. Indicates whether the jemalloc allocator (which is designed for improved performance with threaded applications) is used instead of the phkmalloc allocator (that was the default until NetBSD 5.0). Default: ``yes''. USE_KERBEROS Can be set to ``yes'' or ``no''. Indicates whether Kerberos v5 support is enabled in the various applications that support it. Forced to ``no'' if MKKERBEROS=no. Default: ``yes''. USE_LDAP Can be set to ``yes'' or ``no''. Indicates whether LDAP support is enabled in the various applications that support it. Forced to ``no'' if MKLDAP=no. Default: ``yes''. USE_LIBCSANITIZER Selects the sanitizer in libc to compile userland programs and libraries. Supported values: undefined Enables the micro-UBSan in the user mode (uUBSan) undefined behaviour sanitizer. The code is shared with the kernel mode variation (kUBSan). The runtime runtime differs from the UBSan available in MKSANITIZER. The runtime is stripped down from C++ features, and is invoked with -fsanitize=no-vptr as that sanitizer is not supported. The runtime configuration is restricted to the LIBC_UBSAN environment variable, that is designed to be safe for hardening. The value of USE_LIBCSANITIZER is passed to the C and C++ compilers as the argument to -fsanitize=. Additional sanitizer arguments can be passed through LIBCSANITIZERFLAGS. Disabled if MKLIBCSANITIZER=no. Default: ``undefined''. USE_PAM Can be set to ``yes'' or ``no''. Indicates whether pam(8) support is enabled in the various applications that support it. Forced to ``no'' if MKPAM=no. Default: ``yes''. USE_PIGZGZIP Can be set to ``yes'' or ``no''. Indicates whether pigz(1) is used instead of gzip(1) for multi-threaded gzip compression of the distribution tar sets. Default: ``no''. USE_SANITIZER Selects the sanitizer to compile userland programs and libraries. Supported (one or more, comma-separated) values: address A memory error detector. cfi A control flow detector. dataflow A general data flow analysis. leak A memory leak detector. memory An uninitialized memory read detector. safe-stack Protect against stack-based corruption. scudo The Scudo Hardened Allocator. thread A data race detector. undefined An undefined behavior detector. The value of USE_SANITIZER is passed to the C and C++ compilers as the argument to -fsanitize=. Additional sanitizer arguments can be passed through SANITIZERFLAGS. The list of supported features and their valid combinations depends on the compiler version and target CPU architecture. Disabled if MKSANITIZER=no. Default: ``address''. USE_SKEY Can be set to ``yes'' or ``no''. Indicates whether S/key support is enabled in the various applications that support it. Forced to ``no'' if MKSKEY=no. Note: This is mutually exclusive to USE_PAM!=no. Default: ``no''. USE_SSP Can be set to ``yes'' or ``no''. Indicates whether GCC stack-smashing protection (SSP) support, which detects stack overflows and aborts the program, is enabled. This imposes some performance penalty (approximately 5%). This is disabled internally for standalone programs in /usr/mdec. Forced to ``no'' if NOSSP is defined, usually in the Makefile before any make(1) .include directives. Forced to ``no'' if COVERITY_TOP_CONFIG is defined. Default: ``no'' on alpha, hppa, ia64, and mips; ``yes'' on other platforms if USE_FORT=yes; otherwise ``no''. USE_XZ_SETS Can be set to ``yes'' or ``no''. Indicates whether the distribution tar files are to be compressed with xz(1) instead of gzip(1) or pigz(1). Forced to ``no'' if USE_PIGZGZIP=yes. Default: ``yes'' on aarch64, amd64, and sparc64, ``no'' on other platforms. USE_YP Can be set to ``yes'' or ``no''. Indicates whether YP (NIS) support is enabled in the various applications that support it. Forced to ``no'' if MKYP=no. Default: ``yes''. X11MOTIFPATH Path of the Motif installation to use if MKX11MOTIF=yes. Default: ``/usr/pkg''. X11SRCDIR Directory containing the modular Xorg source. If specified, must be an absolute path. The main modular Xorg source is found in X11SRCDIR/external/mit. Default: NETBSDSRCDIR/../xsrc, if that exists; otherwise ``/usr/xsrc''.
