SRC.CONF(5)		      File Formats Manual		   SRC.CONF(5)

NAME
       src.conf	-- source build	options

DESCRIPTION
       The  src.conf file contains variables that control what components will
       be generated during the build process of	the FreeBSD source  tree;  see
       build(7).

       The src.conf file uses the standard makefile syntax.  However, src.conf
       should  not  specify any	dependencies to	make(1).  Instead, src.conf is
       to set make(1) variables	that control the aspects  of  how  the	system
       builds.

       The  default  location of src.conf is /etc/src.conf, though an alterna-
       tive location can be specified in the make(1) variable SRCCONF.	 Over-
       riding  the  location  of  src.conf may be necessary if the system-wide
       settings	are not	suitable for a particular build.  For  instance,  set-
       ting  SRCCONF  to  /dev/null  effectively  resets all build controls to
       their defaults.

       The only	purpose	of src.conf is	to  control  the  compilation  of  the
       FreeBSD	source code, which is usually located in /usr/src.  As a rule,
       the system administrator	creates	src.conf when the  values  of  certain
       control variables need to be changed from their defaults.

       In  addition, control variables can be specified	for a particular build
       via the -D option of make(1) or in its environment; see environ(7).

       The environment of make(1) for the build	 can  be  controlled  via  the
       SRC_ENV_CONF variable, which defaults to	/etc/src-env.conf.  Some exam-
       ples  that  may	only  be  set in this file are WITH_DIRDEPS_BUILD, and
       WITH_META_MODE, and MAKEOBJDIRPREFIX as they are	environment-only vari-
       ables.

       The values of variables are ignored regardless of their	setting;  even
       if  they	 would	be  set	to "FALSE" or "NO".  The presence of an	option
       causes it to be honored by make(1).

       This list provides a name and short description for variables that  can
       be used for source builds.

       WITHOUT_ACCT
	       Do  not	build  process	accounting tools such as accton(8) and
	       sa(8).

       WITHOUT_ACPI
	       Do not build acpiconf(8), acpidump(8) and related programs.

       WITHOUT_APM
	       Do not build apm(8), apmd(8) and	related	programs.

       WITH_ASAN
	       Build the base system with Address Sanitizer (ASan)  to	detect
	       memory  corruption  bugs	such as	buffer overflows or use-after-
	       free.  Requires that Clang be used as the base system  compiler
	       and  that  the runtime support library is available.  When set,
	       it enforces these options:

	       WITH_LLVM_BINUTILS
	       WITH_LLVM_CXXFILT

       WITHOUT_ASSERT_DEBUG
	       Compile programs	and libraries without the assert(3) checks.

       WITHOUT_AT
	       Do not build at(1) and related utilities.

       WITHOUT_AUDIT
	       Do not build audit support into system programs.

       WITHOUT_AUTHPF
	       Do not build authpf(8).

       WITHOUT_AUTOFS
	       Do not build autofs(5) related programs,	libraries, and	kernel
	       modules.

       WITHOUT_AUTO_OBJ
	       Disable	automatic creation of objdirs.	This is	enabled	by de-
	       fault if	the wanted OBJDIR is writable by the current user.

	       This must be set	in the	environment,  make  command  line,  or
	       /etc/src-env.conf, not /etc/src.conf.

       WITH_BEARSSL
	       Build the BearSSL library.

	       BearSSL	is  a  tiny SSL	library	suitable for embedded environ-
	       ments.  For details see https://www.BearSSL.org/

	       This library is currently only used to perform signature	 veri-
	       fication	  and	related	  operations  for  Verified  Exec  and
	       loader(8).  When	set, these options are also in effect:

	       WITH_LOADER_EFI_SECUREBOOT			       (unless
	       WITHOUT_LOADER_EFI_SECUREBOOT is	set explicitly)
	       WITH_LOADER_VERIEXEC (unless WITHOUT_LOADER_VERIEXEC is set ex-
	       plicitly)
	       WITH_LOADER_VERIEXEC_VECTX			       (unless
	       WITHOUT_LOADER_VERIEXEC_VECTX is	set explicitly)
	       WITH_VERIEXEC (unless WITHOUT_VERIEXEC is set explicitly)

       WITHOUT_BHYVE
	       Do not build or install bhyve(8), associated utilities, and ex-
	       amples.

	       This option only	affects	amd64/amd64.

       WITH_BHYVE_SNAPSHOT
	       Include support for save	and restore  (snapshots)  in  bhyve(8)
	       and bhyvectl(8).

	       This option only	affects	amd64/amd64.

       WITH_BIND_NOW
	       Build  all  binaries  with the DF_BIND_NOW flag set to indicate
	       that the	run-time loader	should perform all relocation process-
	       ing at process startup rather than on demand.  The  combination
	       of  the	BIND_NOW  and  RELRO options provide "full" Relocation
	       Read-Only (RELRO) support.  With	full RELRO the entire  GOT  is
	       made read-only after performing relocation at startup, avoiding
	       GOT overwrite attacks.

       WITHOUT_BLACKLIST
	       Set  this  if  you  do  not  want  to  build  blacklistd(8) and
	       blacklistctl(8).	 When set, these options are also in effect:

	       WITHOUT_BLACKLIST_SUPPORT (unless WITH_BLACKLIST_SUPPORT	is set
	       explicitly)

       WITHOUT_BLACKLIST_SUPPORT
	       Build  some  programs  without  libblacklist(3)	support,  like
	       fingerd(8), ftpd(8), and	sshd(8).

       WITHOUT_BLUETOOTH
	       Do not build Bluetooth related kernel modules, programs and li-
	       braries.

       WITHOUT_BOOT
	       Do not build the	boot blocks and	loader.

       WITHOUT_BOOTPARAMD
	       Do not build or install bootparamd(8).

       WITHOUT_BOOTPD
	       Do not build or install bootpd(8).

       WITHOUT_BSDINSTALL
	       Do not build bsdinstall(8), sade(8), and	related	programs.

       WITHOUT_BSD_CPIO
	       Do  not	build  the  BSD	 licensed  version  of	cpio  based on
	       libarchive(3).

       WITHOUT_BSNMP
	       Do not build or install bsnmpd(1)  and  related	libraries  and
	       data files.

       WITHOUT_BZIP2
	       Do  not	build contributed bzip2	software as a part of the base
	       system.	The option has no effect yet.  When set, these options
	       are also	in effect:

	       WITHOUT_BZIP2_SUPPORT (unless WITH_BZIP2_SUPPORT	is set explic-
	       itly)

       WITHOUT_BZIP2_SUPPORT
	       Build some programs without optional bzip2 support.

       WITHOUT_CALENDAR
	       Do not build calendar(1).

       WITHOUT_CAPSICUM
	       This option has no effect.

       WITHOUT_CAROOT
	       Do not add the trusted certificates from	the Mozilla NSS	bundle
	       to base.

       WITHOUT_CASPER
	       This option has no effect.

       WITH_CCACHE_BUILD
	       Use ccache(1) for the build.  No	configuration is required  ex-
	       cept  to	 install  the  devel/ccache  package.  When using with
	       distcc(1), set  CCACHE_PREFIX=/usr/local/bin/distcc.   The  de-
	       fault  cache directory of $HOME/.ccache will be used, which can
	       be overridden by	setting	CCACHE_DIR.  The  CCACHE_COMPILERCHECK
	       option  defaults	 to  content  when using the in-tree bootstrap
	       compiler, and mtime  when  using	 an  external  compiler.   The
	       CCACHE_CPP2 option is used for Clang but	not GCC.

	       Sharing	a cache	between	multiple work directories requires us-
	       ing a layout similar to /some/prefix/src	 /some/prefix/obj  and
	       an environment such as:

		     CCACHE_BASEDIR='${SRCTOP:H}' MAKEOBJDIRPREFIX='${SRCTOP:H}/obj'

	       See ccache(1) for more configuration options.

       WITHOUT_CCD
	       Do not build geom_ccd(4)	and related utilities.

       WITHOUT_CDDL
	       Do  not build code licensed under Sun's CDDL.  When set,	it en-
	       forces these options:

	       WITHOUT_CTF
	       WITHOUT_DTRACE
	       WITHOUT_LOADER_ZFS
	       WITHOUT_ZFS

       WITHOUT_CLANG
	       Do not build the	Clang C/C++ compiler during the	regular	 phase
	       of the build.  When set,	it enforces these options:

	       WITHOUT_CLANG_EXTRAS
	       WITHOUT_CLANG_FORMAT
	       WITHOUT_CLANG_FULL
	       WITHOUT_LLVM_COV

	       When set, these options are also	in effect:

	       WITHOUT_LLVM_TARGET_AARCH64 (unless WITH_LLVM_TARGET_AARCH64 is
	       set explicitly)
	       WITHOUT_LLVM_TARGET_ALL (unless WITH_LLVM_TARGET_ALL is set ex-
	       plicitly)
	       WITHOUT_LLVM_TARGET_ARM (unless WITH_LLVM_TARGET_ARM is set ex-
	       plicitly)
	       WITHOUT_LLVM_TARGET_POWERPC (unless WITH_LLVM_TARGET_POWERPC is
	       set explicitly)
	       WITHOUT_LLVM_TARGET_RISCV (unless WITH_LLVM_TARGET_RISCV	is set
	       explicitly)

       WITHOUT_CLANG_BOOTSTRAP
	       Do  not	build  the  Clang  C/C++ compiler during the bootstrap
	       phase of	the build.  To be able to build	the system, either gcc
	       or clang	bootstrap must be enabled unless an alternate compiler
	       is provided via XCC.

       WITH_CLANG_EXTRAS
	       Build additional	clang and llvm tools,  such  as	 bugpoint  and
	       clang-format.

       WITH_CLANG_FORMAT
	       Build clang-format.

       WITHOUT_CLANG_FULL
	       Avoid building the ARCMigrate, Rewriter and StaticAnalyzer com-
	       ponents of the Clang C/C++ compiler.

       WITHOUT_CLEAN
	       Do not clean before building world and/or kernel.

       WITHOUT_CPP
	       Do not build cpp(1).

       WITHOUT_CROSS_COMPILER
	       Do  not	build  any  cross compiler in the cross-tools stage of
	       buildworld.  When compiling a different version of FreeBSD than
	       what is installed on the	system,	provide	an alternate  compiler
	       with  XCC  to ensure success.  When compiling with an identical
	       version of FreeBSD to the host, this option may be safely used.
	       This option may also be safe when the host version  of  FreeBSD
	       is  close  to  the sources being	built, but all bets are	off if
	       there have been any changes to the toolchain between  the  ver-
	       sions.  When set, it enforces these options:

	       WITHOUT_CLANG_BOOTSTRAP
	       WITHOUT_ELFTOOLCHAIN_BOOTSTRAP
	       WITHOUT_LLD_BOOTSTRAP

       WITHOUT_CRYPT
	       Do  not build any crypto	code.  When set, it enforces these op-
	       tions:

	       WITHOUT_DMAGENT
	       WITHOUT_KERBEROS
	       WITHOUT_KERBEROS_SUPPORT
	       WITHOUT_LDNS
	       WITHOUT_LDNS_UTILS
	       WITHOUT_LOADER_ZFS
	       WITHOUT_OPENSSH
	       WITHOUT_OPENSSL
	       WITHOUT_OPENSSL_KTLS
	       WITHOUT_PKGBOOTSTRAP
	       WITHOUT_UNBOUND
	       WITHOUT_ZFS

	       When set, these options are also	in effect:

	       WITHOUT_GSSAPI (unless WITH_GSSAPI is set explicitly)

       WITH_CTF
	       Compile with CTF	(Compact C Type	Format)	data.  CTF data	encap-
	       sulates a reduced form  of  debugging  information  similar  to
	       DWARF and the venerable stabs and is required for DTrace.

       WITHOUT_CUSE
	       Do not build CUSE-related programs and libraries.

       WITHOUT_CXGBETOOL
	       Do not build cxgbetool(8)

	       This  is	 a  default  setting on	arm/armv7, powerpc/powerpc and
	       riscv/riscv64.

       WITH_CXGBETOOL
	       Build cxgbetool(8)

	       This  is	 a  default  setting  on  amd64/amd64,	arm64/aarch64,
	       i386/i386, powerpc/powerpc64 and	powerpc/powerpc64le.

       WITHOUT_DEBUG_FILES
	       Avoid  building	or  installing standalone debug	files for each
	       executable binary and shared library.

       WITH_DETECT_TZ_CHANGES
	       Make the	time handling code  detect  changes  to	 the  timezone
	       files.

       WITHOUT_DIALOG
	       Do  not	build  dialog(1), dialog(3), dpv(1), and dpv(3).  When
	       set, it enforces	these options:

	       WITHOUT_BSDINSTALL

       WITHOUT_DICT
	       Do not build the	Webster	dictionary files.

       WITH_DIRDEPS_BUILD
	       This  is	 an  alternate	build	system.	   For	 details   see
	       https://www.crufty.net/sjg/docs/freebsd-meta-mode.htm.	 Build
	       commands	can be seen from the top-level with:
		     make show-valid-targets
	       The build is driven by dirdeps.mk using DIRDEPS stored in Make-
	       file.depend files found in each directory.

	       The build can be	started	from anywhere, and behaves  the	 same.
	       The  initial instance of	make(1)	recursively reads DIRDEPS from
	       Makefile.depend,	computing a graph of  tree  dependencies  from
	       the  current  origin.  Setting NO_DIRDEPS skips checking	dirdep
	       dependencies and	will only build	in the current and  child  di-
	       rectories.   NO_DIRDEPS_BELOW  skips  building  any dirdeps and
	       only build the current directory.

	       This also utilizes the  WITH_META_MODE  logic  for  incremental
	       builds.

	       The build hides commands	executed unless	NO_SILENT is defined.

	       Note  that there	is currently no	mass install feature for this.
	       This build is designed for producing packages, that can then be
	       installed on a target system.

	       The implementation in FreeBSD is	incomplete.  Completion	 would
	       require	leaf  directories for building each kernel and package
	       so that their dependencies can be tracked.  When	 set,  it  en-
	       forces these options:

	       WITH_INSTALL_AS_USER

	       When set, these options are also	in effect:

	       WITH_META_ERROR_TARGET (unless WITHOUT_META_ERROR_TARGET	is set
	       explicitly)
	       WITH_META_MODE (unless WITHOUT_META_MODE	is set explicitly)
	       WITH_STAGING (unless WITHOUT_STAGING is set explicitly)
	       WITH_STAGING_MAN	(unless	WITHOUT_STAGING_MAN is set explicitly)
	       WITH_STAGING_PROG  (unless  WITHOUT_STAGING_PROG	is set explic-
	       itly)
	       WITH_SYSROOT (unless WITHOUT_SYSROOT is set explicitly)

	       This must be set	in the	environment,  make  command  line,  or
	       /etc/src-env.conf, not /etc/src.conf.

       WITH_DIRDEPS_CACHE
	       Cache  result of	dirdeps.mk which can save significant time for
	       subsequent builds.  Depends on WITH_DIRDEPS_BUILD.

	       This must be set	in the	environment,  make  command  line,  or
	       /etc/src-env.conf, not /etc/src.conf.

       WITH_DISK_IMAGE_TOOLS_BOOTSTRAP
	       Build etdump(1),	makefs(8) and mkimg(1) as bootstrap tools.

       WITHOUT_DMAGENT
	       Do not build dma	Mail Transport Agent.

       WITHOUT_DOCCOMPRESS
	       Do  not	install	compressed system documentation.  Only the un-
	       compressed version will be installed.

       WITHOUT_DTRACE
	       Do not build DTrace framework kernel  modules,  libraries,  and
	       user commands.  When set, it enforces these options:

	       WITHOUT_CTF

       WITH_DTRACE_ASAN
	       Compile	userspace  DTrace  code	 (libdtrace,  dtrace(1), lock-
	       stat(1),	plockstat(1)) with address and undefined behavior san-
	       itizers.	 Requires that Clang be	used as	the base  system  com-
	       piler and that the runtime support library is available.

       WITH_DTRACE_TESTS
	       Build	and    install	  the	 DTrace	   test	   suite    in
	       /usr/tests/cddl/usr.sbin/dtrace.	 This test suite is considered
	       experimental on architectures other than	amd64/amd64  and  run-
	       ning it may cause system	instability.

       WITHOUT_DYNAMICROOT
	       Set this	if you do not want to link /bin	and /sbin dynamically.

       WITHOUT_EE
	       Do not build and	install	edit(1), ee(1),	and related programs.

       WITHOUT_EFI
	       Set not to build	efivar(3) and efivar(8).

	       This  is	 a default setting on i386/i386, powerpc/powerpc, pow-
	       erpc/powerpc64, powerpc/powerpc64le and riscv/riscv64.

       WITH_EFI
	       Build efivar(3) and efivar(8).

	       This  is	 a  default  setting  on  amd64/amd64,	arm/armv7  and
	       arm64/aarch64.

       WITHOUT_ELFTOOLCHAIN_BOOTSTRAP
	       Do not build ELF	Tool Chain tools (addr2line, nm, size, strings
	       and  strip)  as	part  of  the bootstrap	process.  An alternate
	       bootstrap tool chain must be provided.

       WITHOUT_EXAMPLES
	       Avoid installing	examples to /usr/share/examples/.

       WITH_EXPERIMENTAL
	       Include experimental features in	the build.

       WITHOUT_FDT
	       Do not build Flattened Device Tree support as part of the  base
	       system.	 This  includes	 the  device  tree  compiler (dtc) and
	       libfdt support library.

	       This is a default setting on amd64/amd64	and i386/i386.

       WITH_FDT
	       Build Flattened Device Tree support as part of the base system.
	       This includes the device	tree compiler (dtc) and	libfdt support
	       library.

	       This is a default setting  on  arm/armv7,  arm64/aarch64,  pow-
	       erpc/powerpc,	powerpc/powerpc64,   powerpc/powerpc64le   and
	       riscv/riscv64.

       WITHOUT_FILE
	       Do not build file(1) and	related	programs.

       WITHOUT_FINGER
	       Do not build or install finger(1) and fingerd(8).

       WITHOUT_FLOPPY
	       Do not build or install programs	for operating floppy disk dri-
	       ver.

       WITHOUT_FORMAT_EXTENSIONS
	       Do not enable -fformat-extensions when  compiling  the  kernel.
	       Also disables all format	checking.

       WITHOUT_FORTH
	       Build bootloaders without Forth support.

	       Do  not	install	 header	files.	This option used to be spelled
	       NO_INCS.	 The option does not work for build targets.

       WITHOUT_INET
	       Do not build programs and libraries related to IPv4 networking.
	       When set, it enforces these options:

	       WITHOUT_INET_SUPPORT

       WITHOUT_INET6

	       Build the base system or	kernel with stack  variables  initial-
	       ized  to	 (compiler defined) debugging patterns on function en-
	       try.  This option requires the clang compiler.

       WITH_INIT_ALL_ZERO
	       Build the base system or	kernel with stack  variables  initial-
	       ized  to	zero on	function entry.	 This option requires that the
	       clang compiler be used.

       WITHOUT_INSTALLLIB
	       Set this	to not install optional	libraries.  For	example,  when
	       creating	 a  nanobsd(8)	image.	 The  option does not work for
	       build targets.

       WITH_INSTALL_AS_USER
	       Make install targets succeed for	non-root users	by  installing
	       files  with  owner and group attributes set to that of the user
	       running the make(1) command.   The  user	 still	must  set  the
	       DESTDIR	variable  to  point  to	a directory where the user has
	       write permissions.

       WITHOUT_IPFILTER
	       Do not build IP Filter package.

	       Do not build kdump(1) and truss(1).

       WITHOUT_KERBEROS
	       Set  this  to  not  build  Kerberos 5 (KTH Heimdal).  When set,
	       these options are also in effect:

	       WITHOUT_GSSAPI (unless WITH_GSSAPI is set explicitly)
	       WITHOUT_KERBEROS_SUPPORT	(unless	WITH_KERBEROS_SUPPORT  is  set
	       explicitly)

	       tion has	no effect at build time.

       WITHOUT_KVM
	       Do  not	build the libkvm library as a part of the base system.
	       The option has no effect	yet.  When set,	these options are also
	       in effect:

	       WITHOUT_KVM_SUPPORT (unless WITH_KVM_SUPPORT is set explicitly)

       WITHOUT_KVM_SUPPORT
	       Build some programs without optional libkvm support.

       WITHOUT_LDNS
	       Setting this variable will prevent the LDNS library from	 being
	       built.  When set, it enforces these options:

	       WITHOUT_LDNS_UTILS
	       WITHOUT_UNBOUND

       WITHOUT_LDNS_UTILS
	       Setting	this variable will prevent building the	LDNS utilities
	       drill(1)	and host(1).

       WITHOUT_LEGACY_CONSOLE
	       Do not build programs that support a legacy PC  console;	 e.g.,
	       kbdcontrol(1) and vidcontrol(1).

       WITHOUT_LIB32
	       On  64-bit  platforms,  do  not	build 32-bit library set and a
	       ld-elf32.so.1 runtime linker.

	       This is a default setting on arm/armv7, i386/i386, powerpc/pow-
	       erpc, powerpc/powerpc64le and riscv/riscv64.

       WITH_LIB32
	       On 64-bit  platforms,  build  the  32-bit  library  set	and  a
	       ld-elf32.so.1 runtime linker.

	       This  is	 a  default  setting on	amd64/amd64, arm64/aarch64 and
	       powerpc/powerpc64.

       WITHOUT_LLD
	       Do not build LLVM's lld linker.

	       This is a default setting on arm/armv7 and riscv/riscv64.

       WITH_LLDB
	       Build the LLDB debugger.

	       This  is	 a  default  setting  on  amd64/amd64,	arm64/aarch64,
	       i386/i386,  powerpc/powerpc, powerpc/powerpc64 and powerpc/pow-
	       erpc64le.

       WITHOUT_LLD_BOOTSTRAP
	       Do not build the	LLD linker during the bootstrap	phase  of  the
	       build.  To be able to build the system an alternate linker must
	       be provided via XLD.

       WITHOUT_LLD_IS_LD
	       Do  not	install	 a  /usr/bin/ld	symlink	to ld.lld.  The	system
	       will not	have a usable tool chain unless	a linker  is  provided
	       some other way.

       WITH_LLVM_ASSERTIONS
	       Enable debugging	assertions in LLVM.

       WITH_LLVM_BINUTILS
	       Install	LLVM's	binutils (without an llvm- prefix), instead of
	       ELF Tool	Chain's	tools.	 This  includes	 addr2line(1),	ar(1),
	       nm(1),	objcopy(1),   ranlib(1),   readelf(1),	 size(1),  and
	       strip(1).  Regardless of	this setting, LLVM tools are used  for
	       c++filt(1)  and	objdump(1).   strings(1) is always provided by
	       ELF Tool	Chain.

       WITHOUT_LLVM_COV
	       Do not build the	llvm-cov(1) tool.

       WITHOUT_LLVM_CXXFILT
	       Install ELF Tool	Chain's	cxxfilt	as c++filt, instead of	LLVM's
	       llvm-cxxfilt.

       WITH_LLVM_FULL_DEBUGINFO
	       Generate	 full  debug information for LLVM libraries and	tools,
	       which uses more disk space and build resources, but allows  for
	       easier debugging.

       WITHOUT_LLVM_TARGET_AARCH64
	       Do   not	  build	  LLVM	 target	  support  for	AArch64.   The
	       LLVM_TARGET_ALL option should be	used rather than this in  most
	       cases.

       WITHOUT_LLVM_TARGET_ALL
	       Only  build  the	 required LLVM target support.	This option is
	       preferred to specific target support options.  When set,	 these
	       options are also	in effect:

	       WITHOUT_LLVM_TARGET_AARCH64 (unless WITH_LLVM_TARGET_AARCH64 is
	       set explicitly)
	       WITHOUT_LLVM_TARGET_ARM (unless WITH_LLVM_TARGET_ARM is set ex-
	       plicitly)
	       WITHOUT_LLVM_TARGET_POWERPC (unless WITH_LLVM_TARGET_POWERPC is
	       set explicitly)
	       WITHOUT_LLVM_TARGET_RISCV (unless WITH_LLVM_TARGET_RISCV	is set
	       explicitly)

       WITHOUT_LLVM_TARGET_ARM
	       Do  not build LLVM target support for ARM.  The LLVM_TARGET_ALL
	       option should be	used rather than this in most cases.

       WITH_LLVM_TARGET_BPF
	       Build LLVM target support for BPF.  The LLVM_TARGET_ALL	option
	       should be used rather than this in most cases.

       WITH_LLVM_TARGET_MIPS
	       Build LLVM target support for MIPS.  The	LLVM_TARGET_ALL	option
	       should be used rather than this in most cases.

       WITHOUT_LLVM_TARGET_POWERPC
	       Do   not	  build	  LLVM	 target	  support  for	PowerPC.   The
	       LLVM_TARGET_ALL option should be	used rather than this in  most
	       cases.

       WITHOUT_LLVM_TARGET_RISCV
	       Do   not	  build	  LLVM	 target	  support   for	 RISC-V.   The
	       LLVM_TARGET_ALL option should be	used rather than this in  most
	       cases.

       WITHOUT_LLVM_TARGET_X86
	       Do  not build LLVM target support for X86.  The LLVM_TARGET_ALL
	       option should be	used rather than this in most cases.

       WITH_LOADER_BIOS_TEXTONLY
	       Use the old, FreeBSD 12 vidconsole.c.  This only	supports  text
	       mode  without  teken,  without any graphics, font or video mode
	       support.	 This setting only affects the	i386  and  amd64  BIOS
	       boot loader.

       WITH_LOADER_EFI_SECUREBOOT
	       Enable  building	 loader(8) with	support	for verification based
	       on certificates obtained	from UEFI.

       WITHOUT_LOADER_GELI
	       Disable inclusion of GELI crypto	support	in the boot chain  bi-

	       This is a default setting  on  arm/armv7,  powerpc/powerpc  and
	       powerpc/powerpc64.

       WITH_LOADER_VERBOSE
	       Build  with extra verbose debugging in the loader.  May explode
	       already nearly too large	loader over the	limit.	Use with care.

       WITH_LOADER_VERIEXEC
	       Enable building loader(8) with support for verification similar
	       to Verified Exec.

	       Depends on WITH_BEARSSL.	 When set, these options are  also  in
	       effect:

	       WITH_LOADER_EFI_SECUREBOOT			       (unless
	       WITHOUT_LOADER_EFI_SECUREBOOT is	set explicitly)
	       WITH_LOADER_VERIEXEC_VECTX			       (unless
	       WITHOUT_LOADER_VERIEXEC_VECTX is	set explicitly)

       WITH_LOADER_VERIEXEC_PASS_MANIFEST
	       Enable building loader(8) with support to pass a	verified mani-
	       fest  to	 the kernel.  The kernel has to	be built with a	module
	       to parse	the manifest.

	       Depends on WITH_LOADER_VERIEXEC.

       WITH_LOADER_VERIEXEC_VECTX
	       Enable building loader(8) with support for hashing and  verify-
	       ing kernel and modules as a side	effect of loading.

	       Depends on WITH_LOADER_VERIEXEC.

       WITHOUT_LOADER_ZFS
	       Do not build ZFS	file system boot loader	support.

       WITHOUT_LOCALES
	       Do not build localization files;	see locale(1).

       WITHOUT_LPR
	       Do not build lpr(1) and related programs.

       WITHOUT_LS_COLORS
	       Build  ls(1)  without  support  for  colors to distinguish file
	       types.

       WITHOUT_MACHDEP_OPTIMIZATIONS
	       Prefer machine-independent non-assembler	code in	libc and libm.

       WITHOUT_MAIL
	       Do not build any	mail support (MUA or MTA).  When set,  it  en-
	       forces these options:

	       WITHOUT_DMAGENT
	       WITHOUT_MAILWRAPPER
	       WITHOUT_SENDMAIL

       WITHOUT_MAILWRAPPER
	       Do not build the	mailwrapper(8) MTA selector.

       WITHOUT_MAKE
	       Do not install make(1) and related support files.

       WITHOUT_MAKE_CHECK_USE_SANDBOX
	       Do  not execute "make check" in limited sandbox mode.  This op-
	       tion should be paired with WITH_INSTALL_AS_USER if executed  as
	       an unprivileged user.  See tests(7) for more details.

       WITH_MALLOC_PRODUCTION
	       Disable	assertions  and	statistics gathering in	malloc(3).  It
	       also defaults the A and J runtime options to off.

       WITHOUT_MAN
	       Do not build manual pages.  When	set, these options are also in
	       effect:

	       WITHOUT_MAN_UTILS (unless WITH_MAN_UTILS	is set explicitly)

       WITHOUT_MANCOMPRESS
	       Do not install compressed man  pages.   Only  the  uncompressed
	       versions	will be	installed.

       WITHOUT_MANSPLITPKG
	       Do  not	split  man  pages  into	their own packages during make
	       package.

       WITHOUT_MAN_UTILS
	       Do  not	build  utilities   for	 manual	  pages,   apropos(1),
	       makewhatis(1),  man(1),	whatis(1), manctl(8), and related sup-
	       port files.

       WITH_META_ERROR_TARGET
	       Enable the META_MODE .ERROR target.

	       This target will	copy the meta  file  of	 a  failed  target  to
	       ERROR_LOGDIR  (default  is  `${SRCTOP:H}/error')	 to  help with
	       failure analysis.  Depends  on  WITH_META_MODE.	 This  default
	       when WITH_DIRDEPS_BUILD is set.

	       This  must  be  set  in	the environment, make command line, or
	       /etc/src-env.conf, not /etc/src.conf.

       WITH_META_MODE
	       Create make(1) meta files when building,	which  can  provide  a
	       reliable	 incremental  build  when  using filemon(4).  The meta
	       file is created in OBJDIR as  target.meta.   These  meta	 files
	       track  the  command that	was executed, its output, and the cur-
	       rent directory.	 The  filemon(4)  module  is  required	unless
	       NO_FILEMON  is  defined.	  When the module is loaded, any files
	       used by the commands executed are tracked as  dependencies  for
	       the  target in its meta file.  The target is considered out-of-
	       date and	rebuilt	if any of these	conditions are	true  compared
	       to the last build:
	          The command to execute changes.
	          The current working directory changes.
	          The target's	meta file is missing.
	          The target's	meta file is missing filemon data when filemon
		   is loaded and a previous run	did not	have it	loaded.
	          [requires filemon(4)] Files read, executed or linked	to are
		   newer than the target.
	          [requires  filemon(4)]  Files  read,	 written,  executed or
		   linked are missing.
	       The meta	files can also be useful for debugging.

	       The build hides commands	that are executed unless NO_SILENT  is
	       defined.	  Errors cause make(1) to show some of its environment
	       for further debugging.

	       The build operates as it	normally would otherwise.  This	option
	       originally invoked a different build system but	that  was  re-
	       named to	WITH_DIRDEPS_BUILD.

	       This  must  be  set  in	the environment, make command line, or
	       /etc/src-env.conf, not /etc/src.conf.

       WITHOUT_MLX5TOOL
	       Do not build mlx5tool(8)

	       This is a default setting  on  arm/armv7,  powerpc/powerpc  and
	       riscv/riscv64.

       WITH_MLX5TOOL
	       Build mlx5tool(8)

	       This  is	 a  default  setting  on  amd64/amd64,	arm64/aarch64,
	       i386/i386, powerpc/powerpc64 and	powerpc/powerpc64le.

       WITHOUT_NETCAT
	       Do not build nc(1) utility.

       WITHOUT_NETGRAPH
	       Do not build applications to support netgraph(4).  When set, it
	       enforces	these options:

	       WITHOUT_BLUETOOTH

	       When set, these options are also	in effect:

	       WITHOUT_NETGRAPH_SUPPORT	(unless	WITH_NETGRAPH_SUPPORT  is  set
	       explicitly)

       WITHOUT_NETGRAPH_SUPPORT
	       Build  libraries, programs, and kernel modules without netgraph
	       support.

       WITHOUT_NETLINK
	       Do not build genl(1) utility.

       WITHOUT_NETLINK_SUPPORT
	       Make libraries and programs use rtsock and sysctl(3) interfaces
	       instead of snl(3).

       WITHOUT_NIS
	       Do not build NIS(8) support and related programs.  If set,  you
	       might  need to adopt your nsswitch.conf(5) and remove `nis' en-
	       tries.

       WITHOUT_NLS
	       Do not build NLS	catalogs.  When	set,  it  enforces  these  op-
	       tions:

	       WITHOUT_NLS_CATALOGS

       WITHOUT_NLS_CATALOGS
	       Do not build NLS	catalog	support	for csh(1).

       WITHOUT_NS_CACHING
	       Disable	name  caching  in the nsswitch subsystem.  The generic
	       caching daemon, nscd(8),	will not be built either if  this  op-
	       tion is set.

       WITHOUT_NTP
	       Do not build ntpd(8) and	related	programs.

       WITHOUT_NUAGEINIT
	       Do not install the limited cloud	init support scripts.

       WITHOUT_NVME
	       Do not build nvme related tools and kernel modules.

	       This  is	 a  default  setting on	arm/armv7, powerpc/powerpc and
	       riscv/riscv64.

       WITH_NVME
	       Build nvme related tools	and kernel modules.

       WITHOUT_OFED
	       Do  not build the "OpenFabrics Enterprise Distribution" Infini-
	       Band software stack, including kernel modules and userspace li-
	       braries.

	       This is a default setting on arm/armv7.	When set, it  enforces
	       these options:

	       WITHOUT_OFED_EXTRA

       WITH_OFED
	       Build  the  "OpenFabrics	 Enterprise  Distribution"  InfiniBand
	       software	stack, including  kernel  modules  and	userspace  li-
	       braries.

	       This  is	 a  default  setting  on  amd64/amd64,	arm64/aarch64,
	       i386/i386,  powerpc/powerpc,  powerpc/powerpc64,	  powerpc/pow-
	       erpc64le	and riscv/riscv64.

       WITHOUT_SOURCELESS_UCODE
	       Do not build kernel modules that	include	sourceless microcode.

       WITHOUT_SPLIT_KERNEL_DEBUG
	       Do not build standalone kernel debug files.  Debug data (if en-
	       abled by	the kernel configuration file) will be included	in the
	       kernel and modules.  When set, it enforces these	options:

	       WITHOUT_KERNEL_SYMBOLS

       WITHOUT_SSP
	       Do not build world with stack smashing protection.

       WITH_STAGING
	       Enable staging of files to a stage  tree.   This	 can  be  best
	       thought of as auto-install to DESTDIR with some extra meta data
	       to   ensure   dependencies   can	  be   tracked.	   Depends  on
	       WITH_DIRDEPS_BUILD.  When set, these options are	 also  in  ef-
	       fect:

	       WITH_STAGING_MAN	(unless	WITHOUT_STAGING_MAN is set explicitly)
	       WITH_STAGING_PROG  (unless  WITHOUT_STAGING_PROG	is set explic-
	       itly)

	       This must be set	in the	environment,  make  command  line,  or
	       /etc/src-env.conf, not /etc/src.conf.

       WITH_STAGING_MAN
	       Enable staging of man pages to stage tree.

       WITH_STAGING_PROG
	       Enable staging of PROGs to stage	tree.

       WITH_STALE_STAGED
	       Check staged files are not stale.

       WITHOUT_STATS
	       Neither	build nor install library "libstats" and dependent bi-
	       naries.

       WITHOUT_SYSCONS
	       Do not build syscons(4) support files such  as  keyboard	 maps,
	       fonts, and screen output	maps.

       WITH_SYSROOT
	       Enable	 use	of   sysroot   during	build.	  Depends   on
	       WITH_DIRDEPS_BUILD.

	       This must be set	in the	environment,  make  command  line,  or
	       /etc/src-env.conf, not /etc/src.conf.

       WITHOUT_SYSTEM_COMPILER
	       Do  not opportunistically skip building a cross-compiler	during
	       the bootstrap phase of the build.  Normally, if	the  currently
	       installed  compiler matches the planned bootstrap compiler type
	       and revision, then it will not be built.	 This does not prevent
	       a compiler from being built for installation though,  only  for
	       building	 one  for  the build itself.  The WITHOUT_CLANG	option
	       controls	that.

       WITHOUT_SYSTEM_LINKER
	       Do not opportunistically	skip building  a  cross-linker	during
	       the  bootstrap  phase of	the build.  Normally, if the currently
	       installed linker	matches	the planned bootstrap linker type  and
	       revision,  then	it will	not be built.  This does not prevent a
	       linker from being  built	 for  installation  though,  only  for
	       building	one for	the build itself.  The WITHOUT_LLD option con-
	       trols that.

	       This option is only relevant when WITH_LLD_BOOTSTRAP is set.

       WITHOUT_TALK
	       Do not build or install talk(1) and talkd(8).

       WITHOUT_TCP_WRAPPERS
	       Do not build or install tcpd(8),	and related utilities.

       WITHOUT_TCSH
	       Do not build and	install	/bin/csh (which	is tcsh(1)).

       WITHOUT_TELNET
	       Do not build telnet(1) and related programs.

       WITHOUT_TESTS
	       Do not build nor	install	the FreeBSD Test Suite in /usr/tests/.
	       See tests(7) for	more details.  This also disables the build of
	       all test-related	dependencies, including	ATF.  When set,	it en-
	       forces these options:

	       WITHOUT_DTRACE_TESTS

	       When set, these options are also	in effect:

	       WITHOUT_GOOGLETEST (unless WITH_GOOGLETEST is set explicitly)
	       WITHOUT_TESTS_SUPPORT (unless WITH_TESTS_SUPPORT	is set explic-
	       itly)

       WITHOUT_TESTS_SUPPORT
	       Disable	the  build of all test-related dependencies, including
	       ATF.  When set, it enforces these options:

	       WITHOUT_GOOGLETEST

       WITHOUT_TEXTPROC
	       Do not build programs used for text processing.

       WITHOUT_TFTP
	       Do not build or install tftp(1) and tftpd(8).

       WITHOUT_TOOLCHAIN
	       Do not install programs used for	program	 development,  compil-
	       ers, debuggers etc.  When set, it enforces these	options:

	       WITHOUT_CLANG
	       WITHOUT_CLANG_EXTRAS
	       WITHOUT_CLANG_FORMAT
	       WITHOUT_CLANG_FULL
	       WITHOUT_LLD
	       WITHOUT_LLDB
	       WITHOUT_LLVM_COV

       WITH_UBSAN
	       Build the base system with Undefined Behavior Sanitizer (UBSan)
	       to  detect various kinds	of undefined behavior at runtime.  Re-
	       quires that Clang be used as the	base system compiler and  that
	       the runtime support library is available

       WITHOUT_UNBOUND
	       Do not build unbound(8) and related programs.

       WITHOUT_UNIFIED_OBJDIR
	       Use  the	 historical  object directory format for build(7) tar-
	       gets.  For native-builds	and builds done	directly in sub-direc-
	       tories the format of  ${MAKEOBJDIRPREFIX}/${.CURDIR}  is	 used,
	       while			  for			  cross-builds
	       ${MAKEOBJDIRPREFIX}/${TARGET}.${TARGET_ARCH}/${.CURDIR}	    is
	       used.

	       This  option  is	 transitional  and will	be removed in a	future
	       version of FreeBSD, at which time WITH_UNIFIED_OBJDIR  will  be
	       enabled permanently.

	       This  must  be  set  in	the environment, make command line, or
	       /etc/src-env.conf, not /etc/src.conf.

       WITHOUT_USB
	       Do not build USB-related	programs and libraries.

       WITHOUT_USB_GADGET_EXAMPLES
	       Do not build USB	gadget kernel modules.

       WITHOUT_UTMPX
	       Do not build user accounting tools such as  last(1),  users(1),
	       who(1), ac(8), lastlogin(8) and utx(8).

       WITH_VERIEXEC
	       Enable  building	 veriexec(8) which loads the contents of veri-
	       fied manifests into the kernel for use by mac_veriexec(4)

	       Depends on WITH_BEARSSL.

       WITHOUT_VI
	       Do not build and	install	vi, view, ex and related programs.

       WITHOUT_VT
	       Do not build vt(4) support files	(fonts and keymaps).

       WITHOUT_WARNS
	       Set this	to not add warning flags to the	compiler  invocations.
	       Useful  as  a  temporary	 workaround  when code enters the tree
	       which triggers warnings in environments that  differ  from  the
	       original	developer.

       WITHOUT_WERROR
	       Set this	to not treat compiler warnings as errors.  Useful as a
	       temporary  workaround when working on fixing compiler warnings.
	       When set, warnings are still printed in the build  log  but  do
	       not fail	the build.

       WITHOUT_WIRELESS
	       Do  not build programs used for 802.11 wireless networks; espe-
	       cially wpa_supplicant(8)	and hostapd(8).	 When set,  these  op-
	       tions are also in effect:

	       WITHOUT_WIRELESS_SUPPORT	 (unless  WITH_WIRELESS_SUPPORT	is set
	       explicitly)

       WITHOUT_WIRELESS_SUPPORT
	       Build libraries,	programs, and kernel  modules  without	802.11
	       wireless	support.

       WITHOUT_WPA_SUPPLICANT_EAPOL
	       Build  wpa_supplicant(8)	 without  support  for the IEEE	802.1X
	       protocol	and without support for	EAP-PEAP,  EAP-TLS,  EAP-LEAP,
	       and EAP-TTLS protocols (usable only via 802.1X).

       WITHOUT_ZFS
	       Do  not build the ZFS file system kernel	module,	libraries such
	       as libbe(3), and	user commands  such  as	 zpool(8)  or  zfs(8).
	       Also  disable  ZFS support in utilities and libraries which im-
	       plement ZFS-specific functionality.

       WITHOUT_ZONEINFO
	       Do not build the	timezone  database.   When  set,  it  enforces
	       these options:

	       WITHOUT_ZONEINFO_LEAPSECONDS_SUPPORT

       WITH_ZONEINFO_LEAPSECONDS_SUPPORT
	       Build leapsecond	information in to the timezone database.
