 .Os
 .Sh NAME
 .Nm src.conf
 .Nd "source build options"
 .Sh DESCRIPTION
 The
 .Nm
 file contains settings that will apply to every build involving the
 .Fx
 source tree; see
 .Xr build 7 .
 .Pp
 The
 .Nm
 file uses the standard makefile syntax.
 However,
 .Nm
 should not specify any dependencies to
 .Xr make 1 .
 Instead,
 .Nm
 is to set
 .Xr make 1
 variables that control the aspects of how the system builds.
 .Pp
 The default location of
 .Nm
 is
 .Pa /etc/src.conf ,
 though an alternative location can be specified in the
 .Xr make 1
 variable
 .Va SRCCONF .
 Overriding the location of
 .Nm
 may be necessary if the system-wide settings are not suitable
 for a particular build.
 For instance, setting
 .Va SRCCONF
 to
 .Pa /dev/null
 effectively resets all build controls to their defaults.
 .Pp
 The only purpose of
 .Nm
 is to control the compilation of the
 .Fx
 source code, which is usually located in
 .Pa /usr/src .
 As a rule, the system administrator creates
 .Nm
 when the values of certain control variables need to be changed
 from their defaults.
 .Pp
 In addition, control variables can be specified
 for a particular build via the
 .Fl D
 option of
 .Xr make 1
 or in its environment; see
 .Xr environ 7 .
 .Pp
 The environment of
 .Xr make 1
 for the build can be controlled via the
 .Va SRC_ENV_CONF
 variable, which defaults to
 .Pa /etc/src-env.conf .
 Some examples that may only be set in this file are
 .Va WITH_DIRDEPS_BUILD ,
 and
 .Va WITH_META_MODE ,
 and
 .Va MAKEOBJDIRPREFIX
 as they are environment-only variables.
 .Pp
 The values of variables are ignored regardless of their setting;
 even if they would be set to
 .Dq Li FALSE
 or
 .Dq Li NO .
 The presence of an option causes
 it to be honored by
 .Xr make 1 .
 .Pp
 This list provides a name and short description for variables
 that can be used for source builds.

 The

 Set to 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.
 .Pp
 This is a default setting on
 mips/mipsel, mips/mips, mips/mips64el, mips/mips64, mips/mipsn32, mips/mipselhf, mips/mipshf, mips/mips64elhf, mips/mips64hf, powerpc/powerpc, powerpc/powerpc64, powerpc/powerpcspe, riscv/riscv64, riscv/riscv64sf and sparc64/sparc64.

 compiler with XCC to ensure success.
 When compiling with an identical version of

 to the host, this option may be safely used.
 This option may also be safe when the host version of
 .Fx
 is close to the sources being built, but all bets are off if there have
 been any changes to the toolchain between the versions.

 .El
 .It Va WITHOUT_DICT
 Set to not build the Webster dictionary files.
 .It Va 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:
 .Dl make show-valid-targets
 The build is driven by dirdeps.mk using
 .Va DIRDEPS
 stored in
 Makefile.depend files found in each directory.
 .Pp
 The build can be started from anywhere, and behaves the same.
 The initial instance of
 .Xr make 1
 recursively reads
 .Va DIRDEPS
 from
 .Pa Makefile.depend ,
 computing a graph of tree dependencies from the current origin.
 Setting
 .Va NO_DIRDEPS
 skips checking dirdep dependencies and will only build in the current
 and child directories.
 .Va NO_DIRDEPS_BELOW
 skips building any dirdeps and only build the current directory.
 .Pp
 This also utilizes the
 .Va WITH_META_MODE
 logic for incremental builds.
 .Pp
 The build hides commands executed unless
 .Va NO_SILENT
 is defined.
 .Pp
 Note that there is currently no mass install feature for this.
 .Pp
 When set, it enforces these options:
