.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.

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.
When set, it enforces these options:

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.
