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 the top level of the source tree, or /etc/src.conf if no src.conf is found in the source tree itself, though an alternative location can be specified in the make(1) variable SRCCONF. Overriding the location of src.conf may be necessary if the system-wide settings are not suitable for a particular build. For instance, setting 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 examples that may only be set in this file are WITH_DIRDEPS_BUILD, and WITH_META_MODE, and MAKEOBJDIRPREFIX as they are environment-only variables.

The values of WITH_ and WITHOUT_ 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(4) related programs, libraries, and kernel modules.

WITHOUT_AUTO_OBJ
    Disable automatic creation of objdirs. This is enabled by default 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 environments. For details see https://www.BearSSL.org/

    This library is currently only used to perform signature verification and related operations for Verified Exec and loader(8).

    Due to size constraints in the BIOS environment on x86, one may need to set LOADERSIZE larger than the default 500000, although often loader is under the 500k limit even with this option. Setting LOADERSIZE larger than 500000 may cause pxeboot(8) to be too large to work. Careful testing of the loader in the target environment when built with a larger limit to establish safe limits is critical because different BIOS environments reserve differing amounts of the low 640k space, making a precise limit for everybody impossible.

    See also WITH_LOADER_PXEBOOT for other considerations. 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 explicitly)
    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 examples.

    This option only affects amd64/amd64 and arm64/aarch64.

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 processing 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
    This option has been renamed to WITHOUT_BLOCKLIST. When set, it enforces these options:

    WITHOUT_BLOCKLIST

    When set, these options are also in effect:

    WITHOUT_BLACKLIST_SUPPORT (unless WITH_BLACKLIST_SUPPORT is set explicitly)
    WITHOUT_BLOCKLIST_SUPPORT (unless WITH_BLOCKLIST_SUPPORT is set explicitly)

WITHOUT_BLACKLIST_SUPPORT
    This option has been renamed to WITHOUT_BLOCKLIST_SUPPORT. When set, it enforces these options:

    WITHOUT_BLOCKLIST_SUPPORT

WITHOUT_BLOCKLIST
    Set this if you do not want to build blocklistd(8) and blocklistctl(8). When set, it enforces these options:

    WITHOUT_BLACKLIST

    When set, these options are also in effect:

    WITHOUT_BLACKLIST_SUPPORT (unless WITH_BLACKLIST_SUPPORT is set explicitly)
    WITHOUT_BLOCKLIST_SUPPORT (unless WITH_BLOCKLIST_SUPPORT is set explicitly)

WITHOUT_BLOCKLIST_SUPPORT
    Build some programs without libblocklist(3) support, like fingerd(8) and sshd(8). When set, it enforces these options:

    WITHOUT_BLACKLIST_SUPPORT

WITHOUT_BLUETOOTH
    Do not build Bluetooth related kernel modules, programs and libraries.

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).

WITH_BRANCH_PROTECTION
    Build with branch protection enabled. On arm64 enable the use of pointer authentication and branch target identification instructions on arm64. These can be used to help mitigate some exploit techniques.

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 explicitly)

WITHOUT_BZIP2_SUPPORT
    Build some programs without optional bzip2 support.

WITHOUT_CALENDAR
    Do not build calendar(1).

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 except to install the devel/ccache or devel/sccache package. When using with distcc(1), set CCACHE_PREFIX=/usr/local/bin/distcc. When using with sccache set CCACHE_NAME=sccache in src.conf(5). The default 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 using 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 enforces these options:

    WITHOUT_CTF

    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 explicitly)
    WITHOUT_LLVM_TARGET_ARM (unless WITH_LLVM_TARGET_ARM is set explicitly)
    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 components of the Clang C/C++ compiler.

WITH_CLEAN
    Clean before building world and/or kernel. Note that recording a new epoch in .clean_build_epoch in the root of the source tree will also force a clean world build. When set, these options are also in effect:

    WITHOUT_DEPEND_CLEANUP (unless WITH_DEPEND_CLEANUP is set explicitly)

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 versions. 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 options:

    WITHOUT_DMAGENT
    WITHOUT_KERBEROS
    WITHOUT_LDNS
    WITHOUT_LDNS_UTILS
    WITHOUT_LOADER_ZFS
    WITHOUT_MITKRB5
    WITHOUT_OPENSSH
    WITHOUT_OPENSSL
    WITHOUT_OPENSSL_KTLS
    WITHOUT_PKGBOOTSTRAP
    WITHOUT_UNBOUND
    WITHOUT_ZFS
    WITHOUT_ZFS_TESTS

    When set, these options are also in effect:

    WITHOUT_KERBEROS_SUPPORT (unless WITH_KERBEROS_SUPPORT is set explicitly)

WITH_CTF
    Compile with CTF (Compact C Type Format) data. CTF data encapsulates 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 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.

WITHOUT_DEPEND_CLEANUP
    Do not attempt to detect if the object tree needs cleaning in part or in whole before building. This speeds up incremental builds, especially when experimenting with build options, but may cause the build to inexplicably fail or produce non-functioning binaries.

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

WITH_DIALOG
    Do build dialog(1), dialog(3), dpv(1), and dpv(3).

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 Makefile.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 directories. 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 enforces 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 explicitly)
    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 uncompressed 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), lockstat(1), plockstat(1)) with address and undefined behavior sanitizers. Requires that Clang be used as the base system compiler 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 running it may cause system instability.

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

WITHOUT_EFI

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.

WITH_IPFILTER_IPFS
    Enable building the ipfs(8) tool to save and restore IPFilter state tables.

WITHOUT_IPFW
    Do not build IPFW tools.

WITHOUT_JAIL
    Do not build tools for the support of jails; e.g., jail(8).

WITHOUT_JEMALLOC_LG_VADDR_WIDE
    Disallow programs to use more than 48 address bits on amd64. Incompatible with LA57 mode. Enabling this option might result in a slight reduction in memory consumption for jemalloc metadata, but also requires disabling LA57 (if hardware supports it).

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

WITHOUT_KERBEROS
    Set this to not build Kerberos. When set, these options are also in effect:

    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/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.

WITHOUT_LLDB
    Do not build the LLDB debugger.

WITH_LLVM_ASSERTIONS
    Enable debugging assertions in LLVM.

WITHOUT_LLVM_BINUTILS
    Install ELF Tool Chain's binary utilities instead of LLVM's. 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

WITH_LLVM_LINK_STATIC_LIBRARIES
    Link LLVM libraries (libllvm, libclang, liblldb) statically into each of the binaries that use them. This means that binaries linked against these libraries, such as clang, ld.lld and lldb will be much larger and position dependent, but will start more quickly.

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:

    Do not build pxeboot on i386/amd64. When the pxeboot is too large, or unneeded, it may be disabled with this option. See WITH_LOADER_PXEBOOT for how to adjust the defaults when you need both a larger /boot/loader and /boot/pxeboot

    This option only has an effect on x86.

WITHOUT_LOADER_UBOOT
    Disable building of ubldr.

    This is a default setting on amd64/amd64, arm64/aarch64, i386/i386, powerpc/powerpc64le and riscv/riscv64.

WITH_LOADER_UBOOT
    Build ubldr.

    This is a default setting on arm/armv7 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. May require a larger LOADERSIZE. 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 manifest 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 verifying 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_LOCATE
    Do not build locate(1) and related programs.

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 enforces 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 option should be paired with WITH_INSTALL_AS_USER if executed as an unprivileged user. See tests(7) for more details.

WITHOUT_MALLOC_PRODUCTION
    Enable assertions and statistics gathering in malloc(3). The run-time options opt.abort, opt.abort_conf, and opt.junk also default to true.

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.

WITH_MANSPLITPKG
    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 support 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 current 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 renamed to WITH_DIRDEPS_BUILD.

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

WITHOUT_MITKRB5
    Set this to build KTH Heimdal instead of MIT Kerberos 5.

WITHOUT_MLX5TOOL
    Do not build mlx5tool(8)

    This is a default setting on arm/armv7 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:

    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’ entries.

    Do not build NLS catalogs. When set, it enforces these options:

    WITHOUT_NLS_CATALOGS

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

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

WITHOUT_NUAGEINIT
    Do not install the limited cloud init support scripts.

WITHOUT_OFED
    Do not build the “OpenFabrics Enterprise Distribution” InfiniBand software stack, including kernel modules and userspace libraries.

    WITHOUT_KERBEROS
    WITHOUT_LDNS
    WITHOUT_LDNS_UTILS
    WITHOUT_LOADER_ZFS
    WITHOUT_MITKRB5
    WITHOUT_OPENSSH
    WITHOUT_OPENSSL_KTLS
    WITHOUT_PKGBOOTSTRAP
    WITHOUT_UNBOUND

WITHOUT_RADIUS_SUPPORT
    Do not build radius support into various applications, like pam_radius(8) and ppp(8).

WITH_RATELIMIT
    Build the system with rate limit support.

    This makes SO_MAX_PACING_RATE effective in getsockopt(2), and txrlimit support in ifconfig(8), by proxy.

WITHOUT_RBOOTD
    Do not build or install rbootd(8).

WITHOUT_RELRO
    Do not apply the Relocation Read-Only (RELRO) vulnerability mitigation. See also the BIND_NOW option.

    WITHOUT_KERNEL_SYMBOLS

WITHOUT_SSP
    Do not build world with stack smashing protection. See mitigations(7) for more information.

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 effect:

    WITH_STAGING_MAN (unless WITHOUT_STAGING_MAN is set explicitly)
    WITH_STAGING_PROG (unless WITHOUT_STAGING_PROG is set explicitly)

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 controls 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_DTRACE_TESTS
    WITHOUT_ZFS_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 explicitly)

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

    WITHOUT_CLANG_EXTRAS
    WITHOUT_CLANG_FORMAT
    WITHOUT_CLANG_FULL
    WITHOUT_LLD
    WITHOUT_LLDB
    WITHOUT_LLVM_COV

    When set, these options are also in effect:

    WITHOUT_LLVM_BINUTILS (unless WITH_LLVM_BINUTILS is set explicitly)

WITH_UBSAN
    Build the base system with Undefined Behavior Sanitizer (UBSan) to detect various kinds of undefined behavior at runtime. Requires 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.

WITH_UNDEFINED_VERSION
    Link libraries with --undefined-version which permits version maps to contain symbols that are not present in the library. If this is necessary to build a particular configuration, a bug is present and the configuration should be reported.

WITHOUT_UNIFIED_OBJDIR
    Use the historical object directory format for build(7) targets. For native-builds and builds done directly in sub-directories 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 verified 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; especially wpa_supplicant(8) and hostapd(8). When set, these options 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).

WITH_ZEROREGS
    Build the basesystem with code to zero caller-used register contents on function return. This prevents leaking temporary values for side channel attacks. Additionally this reduces the number of usable ROP gadgets for attackers.

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 implement ZFS-specific functionality. When set, it enforces these options:

    WITHOUT_ZFS_TESTS

WITHOUT_ZFS_TESTS
    Do not build and install the legacy ZFS test suite.

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. This option violates p1003.1 and all other applicable standards, and is known to cause unexpected issues with date/time handling in many applications and programming languages.

The following options accept a single value from a list of valid values.

INIT_ALL
    Control default initialization of stack variables in C and C++ code. Options other than none require the Clang compiler or GCC 12.0 or later. The default value is none. Valid values are:

    none
        Do not initialize stack variables (standard C/C++ behavior).

    pattern
        Build the base system or kernel with stack variables initialized to (compiler defined) debugging patterns on function entry.

    zero
        Build the base system or kernel with stack variables initialized to zero on function entry. This value is converted to none for amd64 kernel builds due to incompatibility with ifunc memset.

LIBC_MALLOC
    Specify the malloc(3) implementation used by libc. The default value is jemalloc. Valid values are:

    jemalloc

    Other implementations are expected in the future in both FreeBSD and downstream consumers.
