.Os
.Sh NAME
.Nm src.conf
.Nd "source build options"
.Sh DESCRIPTION
The
.Nm
file contains variables that control what components will be generated during
the build process of 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
.Va WITH_
and
.Va WITHOUT_
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.
.Bl -tag -width indent
.It Va WITHOUT_ACCT
Do not build process accounting tools such as

Requires that Clang be used as the base system compiler
and that the runtime support library is available.
When set, it enforces these options:
.Pp
.Bl -item -compact
.It
.Va WITH_LLVM_BINUTILS
.It
.Va WITH_LLVM_CXXFILT
.El
.It Va WITHOUT_ASSERT_DEBUG
Compile programs and libraries without the

This is enabled by default if the wanted OBJDIR is writable by the current user.
.Pp
This must be set in the environment, make command line, or
.Pa /etc/src-env.conf ,
not
.Pa /etc/src.conf .
.It Va WITH_BEARSSL
Build the BearSSL library.
.Pp
BearSSL is a tiny SSL library suitable for embedded environments.
For details see
.Lk https://www.BearSSL.org/
.Pp

signature verification and related operations
for Verified Exec and
.Xr loader 8 .
When set, these options are also in effect:
.Pp
.Bl -inset -compact
.It Va WITH_LOADER_EFI_SECUREBOOT
(unless
.Va WITHOUT_LOADER_EFI_SECUREBOOT
is set explicitly)
.It Va WITH_LOADER_VERIEXEC
(unless
.Va WITHOUT_LOADER_VERIEXEC
is set explicitly)
.It Va WITH_LOADER_VERIEXEC_VECTX

and
.Xr bhyvectl 8 .
.Pp
This option only affects amd64/amd64.
.It Va WITH_BIND_NOW
Build all binaries with the
.Dv 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
.Va BIND_NOW
and
.Va 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.
.It Va WITHOUT_BLACKLIST
Set this if you do not want to build
.Xr blacklistd 8
and
.Xr blacklistctl 8 .
When set, these options are also in effect:
.Pp
.Bl -inset -compact

.Ef
When set, these options are also in effect:
.Pp
.Bl -inset -compact
.It Va WITHOUT_BZIP2_SUPPORT
(unless
.Va WITH_BZIP2_SUPPORT
is set explicitly)
.El
.It Va WITHOUT_BZIP2_SUPPORT
Build some programs without optional bzip2 support.
.It Va WITHOUT_CALENDAR
Do not build
.Xr calendar 1 .
.It Va WITHOUT_CAPSICUM
This option has no effect.
.It Va WITHOUT_CAROOT
Do not add the trusted certificates from the Mozilla NSS bundle to
base.
.It Va WITHOUT_CASPER
This option has no effect.
.It Va WITH_CCACHE_BUILD
Use
.Xr ccache 1
for the build.
No configuration is required except to install the
.Sy devel/ccache
package.
When using with
.Xr distcc 1 ,
set
.Sy CCACHE_PREFIX=/usr/local/bin/distcc .
The default cache directory of
.Pa $HOME/.ccache
will be used, which can be overridden by setting
.Sy CCACHE_DIR .
The
.Sy CCACHE_COMPILERCHECK
option defaults to
.Sy content
when using the in-tree bootstrap compiler,
and
.Sy mtime
when using an external compiler.
The
.Sy CCACHE_CPP2
option is used for Clang but not GCC.
.Pp
Sharing a cache between multiple work directories requires using a layout
similar to
.Pa /some/prefix/src
.Pa /some/prefix/obj
and an environment such as:
.Bd -literal -offset indent
CCACHE_BASEDIR='${SRCTOP:H}' MAKEOBJDIRPREFIX='${SRCTOP:H}/obj'

(unless
.Va WITH_LLVM_TARGET_RISCV
is set explicitly)
.El
.It Va WITHOUT_CLANG_BOOTSTRAP

Build additional clang and llvm tools, such as bugpoint and
clang-format.
.It Va WITH_CLANG_FORMAT
Build clang-format.

When compiling a different version of
.Fx
than what is installed on the system, provide an alternate
compiler with XCC to ensure success.
When compiling with an identical version of
.Fx
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:
.Pp
.Bl -item -compact
.It
.Va WITHOUT_CLANG_BOOTSTRAP
.It
.Va WITHOUT_ELFTOOLCHAIN_BOOTSTRAP
.It

.Bl -inset -compact
.It Va WITHOUT_GSSAPI
(unless
.Va WITH_GSSAPI
is set explicitly)
.El
.It Va 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.
.It Va WITHOUT_CUSE
Do not build CUSE-related programs and libraries.
.It Va WITHOUT_CXGBETOOL
Do not build
.Xr cxgbetool 8
.Pp
This is a default setting on

.It Va WITHOUT_DICT
Do not build the Webster dictionary files.
.It Va 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:
.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.
This build is designed for producing packages, that can then be installed
on a target system.
.Pp
The implementation in
.Fx
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:
.Pp
.Bl -item -compact
