3.Dt SRC.CONF 5
4.Os
5.Sh NAME
6.Nm src.conf
7.Nd "source build options"
8.Sh DESCRIPTION
9The
10.Nm
11file contains variables that control what components will be generated during
12the build process of the
13.Fx
14source tree; see
15.Xr build 7 .
16.Pp
17The
18.Nm
19file uses the standard makefile syntax.
20However,
21.Nm
22should not specify any dependencies to
23.Xr make 1 .
24Instead,
25.Nm
26is to set
27.Xr make 1
28variables that control the aspects of how the system builds.
29.Pp
30The default location of
31.Nm
32is
33.Pa /etc/src.conf ,
34though an alternative location can be specified in the
35.Xr make 1
36variable
37.Va SRCCONF .
38Overriding the location of
39.Nm
40may be necessary if the system-wide settings are not suitable
41for a particular build.
42For instance, setting
43.Va SRCCONF
44to
45.Pa /dev/null
46effectively resets all build controls to their defaults.
47.Pp
48The only purpose of
49.Nm
50is to control the compilation of the
51.Fx
52source code, which is usually located in
53.Pa /usr/src .
54As a rule, the system administrator creates
55.Nm
56when the values of certain control variables need to be changed
57from their defaults.
58.Pp
59In addition, control variables can be specified
60for a particular build via the
61.Fl D
62option of
63.Xr make 1
64or in its environment; see
65.Xr environ 7 .
66.Pp
67The environment of
68.Xr make 1
69for the build can be controlled via the
70.Va SRC_ENV_CONF
71variable, which defaults to
72.Pa /etc/src-env.conf .
73Some examples that may only be set in this file are
74.Va WITH_DIRDEPS_BUILD ,
75and
76.Va WITH_META_MODE ,
77and
78.Va MAKEOBJDIRPREFIX
79as they are environment-only variables.
80.Pp
81The values of
82.Va WITH_
83and
84.Va WITHOUT_
85variables are ignored regardless of their setting;
86even if they would be set to
87.Dq Li FALSE
88or
89.Dq Li NO .
90The presence of an option causes
91it to be honored by
92.Xr make 1 .
93.Pp
94This list provides a name and short description for variables
95that can be used for source builds.
96.Bl -tag -width indent

139Do not build
140.Xr autofs 5
141related programs, libraries, and kernel modules.
142.It Va WITHOUT_AUTO_OBJ
143Disable automatic creation of objdirs.
144This is enabled by default if the wanted OBJDIR is writable by the current user.
145.Pp
146This must be set in the environment, make command line, or
147.Pa /etc/src-env.conf ,
148not
149.Pa /etc/src.conf .
150.It Va WITH_BEARSSL
151Build the BearSSL library.
152.Pp
153BearSSL is a tiny SSL library suitable for embedded environments.

156.Pp
157This library is currently only used to perform
158signature verification and related operations
159for Verified Exec and
160.Xr loader 8 .
161When set, these options are also in effect:
162.Pp
163.Bl -inset -compact
164.It Va WITH_LOADER_EFI_SECUREBOOT

193This option only affects amd64/amd64.
194.It Va WITH_BIND_NOW
195Build all binaries with the
196.Dv DF_BIND_NOW
197flag set to indicate that the run-time loader should perform all relocation
198processing at process startup rather than on demand.
199The combination of the
200.Va BIND_NOW
201and
202.Va RELRO
203options provide "full" Relocation Read-Only (RELRO) support.
204With full RELRO the entire GOT is made read-only after performing relocation at
205startup, avoiding GOT overwrite attacks.
206.It Va WITHOUT_BLACKLIST
207Set this if you do not want to build
208.Xr blacklistd 8
209and
210.Xr blacklistctl 8 .
211When set, these options are also in effect:
212.Pp

246Do not build or install
247.Xr bsnmpd 1
248and related libraries and data files.
249.It Va WITHOUT_BZIP2
250Do not build contributed bzip2 software as a part of the base system.
251.Bf -symbolic
252The option has no effect yet.
253.Ef
254When set, these options are also in effect:
255.Pp
256.Bl -inset -compact
257.It Va WITHOUT_BZIP2_SUPPORT

271base.
272.It Va WITHOUT_CASPER
273This option has no effect.
274.It Va WITH_CCACHE_BUILD
275Use
276.Xr ccache 1
277for the build.
278No configuration is required except to install the
279.Sy devel/ccache
280package.
281When using with
282.Xr distcc 1 ,
283set
284.Sy CCACHE_PREFIX=/usr/local/bin/distcc .
285The default cache directory of
286.Pa $HOME/.ccache
287will be used, which can be overridden by setting
288.Sy CCACHE_DIR .
289The
290.Sy CCACHE_COMPILERCHECK
291option defaults to
292.Sy content
293when using the in-tree bootstrap compiler,
294and
295.Sy mtime
296when using an external compiler.
297The
298.Sy CCACHE_CPP2
299option is used for Clang but not GCC.
300.Pp
301Sharing a cache between multiple work directories requires using a layout
302similar to
303.Pa /some/prefix/src
304.Pa /some/prefix/obj
305and an environment such as:
306.Bd -literal -offset indent

369.El
370.It Va WITHOUT_CLANG_BOOTSTRAP
371Do not build the Clang C/C++ compiler during the bootstrap phase of
372the build.
373To be able to build the system, either gcc or clang bootstrap must be
374enabled unless an alternate compiler is provided via XCC.
375.It Va WITH_CLANG_EXTRAS
376Build additional clang and llvm tools, such as bugpoint and
377clang-format.
378.It Va WITH_CLANG_FORMAT

392than what is installed on the system, provide an alternate
393compiler with XCC to ensure success.
394When compiling with an identical version of
395.Fx
396to the host, this option may be safely used.
397This option may also be safe when the host version of
398.Fx
399is close to the sources being built, but all bets are off if there have
400been any changes to the toolchain between the versions.
401When set, it enforces these options:

450.It Va WITH_CTF
451Compile with CTF (Compact C Type Format) data.
452CTF data encapsulates a reduced form of debugging information
453similar to DWARF and the venerable stabs and is required for DTrace.
454.It Va WITHOUT_CUSE
455Do not build CUSE-related programs and libraries.

483This is an alternate build system.
484For details see
485https://www.crufty.net/sjg/docs/freebsd-meta-mode.htm.
486Build commands can be seen from the top-level with:
487.Dl make show-valid-targets
488The build is driven by dirdeps.mk using
489.Va DIRDEPS
490stored in
491Makefile.depend files found in each directory.
492.Pp
493The build can be started from anywhere, and behaves the same.
494The initial instance of
495.Xr make 1
496recursively reads
497.Va DIRDEPS
498from
499.Pa Makefile.depend ,
500computing a graph of tree dependencies from the current origin.
501Setting
502.Va NO_DIRDEPS
503skips checking dirdep dependencies and will only build in the current
504and child directories.
505.Va NO_DIRDEPS_BELOW
506skips building any dirdeps and only build the current directory.
507.Pp
508This also utilizes the
509.Va WITH_META_MODE
510logic for incremental builds.
511.Pp
512The build hides commands executed unless
513.Va NO_SILENT
514is defined.
515.Pp
516Note that there is currently no mass install feature for this.
517This build is designed for producing packages, that can then be installed
518on a target system.
519.Pp
520The implementation in
521.Fx
522is incomplete.
523Completion would require leaf directories for building each kernel
524and package so that their dependencies can be tracked.
525When set, it enforces these options:
