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 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 in- stance, setting SRCCONF to /dev/null effectively resets all build con- trols 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 WITH_ and WITHOUT_ variables are ignored regardless of their setting; even if they would be set to "FALSE" or "NO". The pres- ence 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 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). 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 re- serve 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 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 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 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 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, these options are also in effect: 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). 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). WITH_BRANCH_PROTECTION Build with branch protection enabled. On arm64 enable the use of pointer authentication and branch target identification in- structions 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 explic- itly) 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 ex- cept 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 di- rectory of $HOME/.ccache will be used, which can be overridden by setting CCACHE_DIR. The CCACHE_COMPILERCHECK option de- faults to content when using the in-tree bootstrap compiler, and mtime when using an external compiler. The CCACHE_CPP2 op- tion is used for Clang but not GCC. Sharing a cache between multiple work directories requires us- ing a layout similar to /some/prefix/src /some/prefix/obj and an environment such as: CCACHE_BASEDIR='${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_ZFS_TESTS 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. 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. 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_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 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 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. 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 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/powerpc64 and powerpc/powerpc64le. WITH_EFI Build efivar(3) and efivar(8). This is a default setting on amd64/amd64, arm/armv7, arm64/aarch64 and riscv/riscv64. 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/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_INCLUDES 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 Do not build programs and libraries related to IPv6 networking. When set, it enforces these options: WITHOUT_INET6_SUPPORT WITHOUT_INET6_SUPPORT Build libraries, programs, and kernel modules without IPv6 sup- port. WITHOUT_INETD Do not build inetd(8). WITHOUT_INET_SUPPORT Build libraries, programs, and kernel modules without IPv4 sup- port. 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. WITHOUT_IPFW Do not build IPFW tools. WITHOUT_IPSEC_SUPPORT Do not build the kernel with ipsec(4) support. This option is needed for ipsec(4) and tcpmd5(4). WITHOUT_ISCSI Do not build iscsid(8) and related utilities. 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 meta- data, 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_KERBEROS_SUPPORT (unless WITH_KERBEROS_SUPPORT is set explicitly) WITHOUT_KERBEROS_SUPPORT Build some programs without Kerberos support, like ssh(1), telnet(1), and sshd(8). WITH_KERNEL_BIN Generate and install kernel.bin from kernel as part of the nor- mal build and install processes for the kernel. Available only on arm and arm64. Usually this will be added to the kernel config file with: makeoptions WITH_KERNEL_BIN=1 though it can also be used on the command line. WITH_KERNEL_RETPOLINE Enable the "retpoline" mitigation for CVE-2017-5715 in the ker- nel build. WITHOUT_KERNEL_SYMBOLS Do not install standalone kernel debug symbol files. This op- 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- erpc64le 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. 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/powerpc64 and powerpc/powerpc64le. 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. 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 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. 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. WITHOUT_LOADER_BIOS_TEXTONLY Include graphics, font and video mode support in 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- naries. This is a default setting on powerpc/powerpc64 and powerpc/pow- erpc64le. WITH_LOADER_GELI Build GELI bootloader support. This is a default setting on amd64/amd64, arm/armv7, arm64/aarch64, i386/i386 and riscv/riscv64. WITHOUT_LOADER_IA32 Do not build the 32-bit UEFI loader. This is a default setting on arm/armv7, arm64/aarch64, i386/i386, powerpc/powerpc64, powerpc/powerpc64le and riscv/riscv64. WITH_LOADER_IA32 Build the 32-bit UEFI loader. This is a default setting on amd64/amd64.

WITHOUT_LOADER_LUA Do not build LUA bindings for the boot loader. This is a default setting on powerpc/powerpc64 and powerpc/pow- erpc64le. WITH_LOADER_LUA Build LUA bindings for the boot loader. This is a default setting on amd64/amd64, arm/armv7, arm64/aarch64, i386/i386 and riscv/riscv64. WITHOUT_LOADER_OFW Disable building of openfirmware bootloader components. This is a default setting on amd64/amd64, arm/armv7, arm64/aarch64, i386/i386 and riscv/riscv64. WITH_LOADER_OFW Build openfirmware bootloader components. This is a default setting on powerpc/powerpc64 and powerpc/pow- erpc64le. WITHOUT_LOADER_PXEBOOT 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 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_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 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. 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 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_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.

WITHOUT_QUOTAS Do not build quota(1) and related programs. 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_REPRODUCIBLE_BUILD Include build metadata (such as the build time, user, and host) in the kernel, boot loaders, and uname output. Successive builds will not be bit-for-bit identical. WITHOUT_RESCUE Do not build rescue(8). WITH_RETPOLINE Build the base system with the retpoline speculative execution vulnerability mitigation for CVE-2017-5715.

WITHOUT_SOURCELESS Do not build kernel modules that include sourceless code (ei- ther microcode or native code for host CPU). When set, it en- forces these options: WITHOUT_SOURCELESS_HOST WITHOUT_SOURCELESS_UCODE WITHOUT_SOURCELESS_HOST Do not build kernel modules that include sourceless native code for host CPU. 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. 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 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 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 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 When set, these options are also in effect: WITHOUT_LLVM_BINUTILS (unless WITH_LLVM_BINUTILS is set explic- itly) 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. 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) 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). 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 im- plement 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 IEEE Std 1003.1 ("POSIX.1") and all other ap- plicable 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 val- ues. 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++ be- havior). 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 incom- patability 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.
