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 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 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.

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.

WITHOUT_BINUTILS

Do not build or install GNU as(1), ld.bfd(1), and objdump(1) as part of the normal system build.

This is a default setting on arm64/aarch64, riscv/riscv64 and riscv/riscv64sf. When set, it enforces these options:

WITHOUT_GDB

WITH_BINUTILS

Set to build and install GNU as(1), objdump(1), and for some CPU architectures ld.bfd(1) as part of the normal system build.

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_CROSS_COMPILER

Set to 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_BINUTILS_BOOTSTRAP

WITH_DIRDEPS_BUILD

This is an experimental build system. For details see http://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.

When set, it enforces these options:

WITH_INSTALL_AS_USER

When set, these options are also in effect:

WITH_META_MODE: (unless WITHOUT_META_MODE is set explicitly)

Set to not build the mailwrapper(8) MTA selector.

WITHOUT_MAKE

Set to not install make(1) and related support files.

WITHOUT_MAKE_CHECK_USE_SANDBOX

Set to 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.

Set to enable assertions and statistics gathering in malloc(3). It also defaults the A and J runtime options to on.

WITHOUT_MAN

Set to not build utilities for manual pages, apropos(1), makewhatis(1), man(1), whatis(1), manctl(8), and related support files.

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.

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 and WITHOUT_GCC options control those.

WITHOUT_SYSTEM_LINKER

Set to not build unbound(8) and related programs.

WITHOUT_UNIFIED_OBJDIR

Set to 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 will be enabled permanently.

Set to not build and install vi, view, ex and related programs.

WITHOUT_VT

Set to not build vt(4) support files (fonts and keymaps).

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_WIRELESS

Set to 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)

Set to build libraries, programs, and kernel modules without 802.11 wireless support.

WITHOUT_WPA_SUPPLICANT_EAPOL
