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 the top level of the source tree, or
33.Pa /etc/src.conf
34if no
35.Nm
36is found in the source tree itself,
37though an alternative location can be specified in the
38.Xr make 1
39variable
40.Va SRCCONF .
41Overriding the location of
42.Nm
43may be necessary if the system-wide settings are not suitable
44for a particular build.
45For instance, setting
46.Va SRCCONF
47to
48.Pa /dev/null
49effectively resets all build controls to their defaults.
50.Pp
51The only purpose of
52.Nm
53is to control the compilation of the
54.Fx
55source code, which is usually located in
56.Pa /usr/src .
57As a rule, the system administrator creates
58.Nm
59when the values of certain control variables need to be changed
60from their defaults.
61.Pp
62In addition, control variables can be specified
63for a particular build via the
64.Fl D
65option of
66.Xr make 1
67or in its environment; see
68.Xr environ 7 .
69.Pp
70The environment of
71.Xr make 1
72for the build can be controlled via the
73.Va SRC_ENV_CONF
74variable, which defaults to
75.Pa /etc/src-env.conf .
76Some examples that may only be set in this file are
77.Va WITH_DIRDEPS_BUILD ,
78and
79.Va WITH_META_MODE ,
80and
81.Va MAKEOBJDIRPREFIX
82as they are environment-only variables.
83.Pp
84The values of
85.Va WITH_
86and
87.Va WITHOUT_
88variables are ignored regardless of their setting;
89even if they would be set to
90.Dq Li FALSE
91or
92.Dq Li NO .
93The presence of an option causes
94it to be honored by
95.Xr make 1 .
96.Pp
97This list provides a name and short description for variables
98that can be used for source builds.
99.Bl -tag -width indent
100.It Va WITHOUT_ACCT
101Do not build process accounting tools such as
102.Xr accton 8
103and
104.Xr sa 8 .
105.It Va WITHOUT_ACPI
106Do not build
107.Xr acpiconf 8 ,
108.Xr acpidump 8
109and related programs.
110.It Va WITHOUT_APM
111Do not build
112.Xr apm 8 ,
113.Xr apmd 8
114and related programs.
115.It Va WITH_ASAN
116Build the base system with Address Sanitizer (ASan) to detect
117memory corruption bugs such as buffer overflows or use-after-free.
118Requires that Clang be used as the base system compiler
119and that the runtime support library is available.
120When set, it enforces these options:
121.Pp
122.Bl -item -compact
123.It
124.Va WITH_LLVM_BINUTILS
125.It
126.Va WITH_LLVM_CXXFILT
127.El
128.It Va WITHOUT_ASSERT_DEBUG
129Compile programs and libraries without the
130.Xr assert 3
131checks.
132.It Va WITHOUT_AT
133Do not build
134.Xr at 1
135and related utilities.
136.It Va WITHOUT_AUDIT
137Do not build audit support into system programs.
138.It Va WITHOUT_AUTHPF
139Do not build
140.Xr authpf 8 .
141.It Va WITHOUT_AUTOFS
142Do not build
143.Xr autofs 4
144related programs, libraries, and kernel modules.
145.It Va WITHOUT_AUTO_OBJ
146Disable automatic creation of objdirs.
147This is enabled by default if the wanted OBJDIR is writable by the current user.
148.Pp
149This must be set in the environment, make command line, or
150.Pa /etc/src-env.conf ,
151not
152.Pa /etc/src.conf .
153.It Va WITH_BEARSSL
154Build the BearSSL library.
155.Pp
156BearSSL is a tiny SSL library suitable for embedded environments.
157For details see
158.Lk https://www.BearSSL.org/
159.Pp
160This library is currently only used to perform
161signature verification and related operations
162for Verified Exec and
163.Xr loader 8 .
164.Pp
165Due to size constraints in the BIOS environment on x86, one may need to set
166.Va LOADERSIZE
167larger than the
168default 500000, although often loader is under the 500k limit even with
169this option.
170Setting
171.Va LOADERSIZE
172larger than 500000 may cause
173.Xr pxeboot 8
174to be too large to work.
175Careful testing of the loader in the target environment when built with a larger
176limit to establish safe limits is critical because different BIOS environments
177reserve differing amounts of the low 640k space, making a precise limit for
178everybody impossible.
179.Pp
180See also
181.Va WITH_LOADER_PXEBOOT
182for other considerations.
183When set, these options are also in effect:
184.Pp
185.Bl -inset -compact
186.It Va WITH_LOADER_EFI_SECUREBOOT
187(unless
188.Va WITHOUT_LOADER_EFI_SECUREBOOT
189is set explicitly)

191(unless
192.Va WITHOUT_LOADER_VERIEXEC
193is set explicitly)
194.It Va WITH_LOADER_VERIEXEC_VECTX
195(unless
196.Va WITHOUT_LOADER_VERIEXEC_VECTX
197is set explicitly)
198.It Va WITH_VERIEXEC
199(unless
200.Va WITHOUT_VERIEXEC
201is set explicitly)
202.El
203.It Va WITHOUT_BHYVE
204Do not build or install
205.Xr bhyve 8 ,
206associated utilities, and examples.
207.Pp
208This option only affects amd64/amd64 and arm64/aarch64.
209.It Va WITH_BHYVE_SNAPSHOT
210Include support for save and restore (snapshots) in
211.Xr bhyve 8
212and
213.Xr bhyvectl 8 .
214.Pp
215This option only affects amd64/amd64.
216.It Va WITH_BIND_NOW
217Build all binaries with the
218.Dv DF_BIND_NOW
219flag set to indicate that the run-time loader should perform all relocation
220processing at process startup rather than on demand.
221The combination of the
222.Va BIND_NOW
223and
224.Va RELRO
225options provide "full" Relocation Read-Only (RELRO) support.
226With full RELRO the entire GOT is made read-only after performing relocation at
227startup, avoiding GOT overwrite attacks.
228.It Va WITHOUT_BLACKLIST
229Set this if you do not want to build
230.Xr blacklistd 8
231and
232.Xr blacklistctl 8 .
233When set, these options are also in effect:
234.Pp
235.Bl -inset -compact
236.It Va WITHOUT_BLACKLIST_SUPPORT
237(unless
238.Va WITH_BLACKLIST_SUPPORT
239is set explicitly)
240.El
241.It Va WITHOUT_BLACKLIST_SUPPORT
242Build some programs without
243.Xr libblacklist 3
244support, like
245.Xr fingerd 8
246and
247.Xr sshd 8 .
248.It Va WITHOUT_BLUETOOTH
249Do not build Bluetooth related kernel modules, programs and libraries.
250.It Va WITHOUT_BOOT
251Do not build the boot blocks and loader.
252.It Va WITHOUT_BOOTPARAMD
253Do not build or install
254.Xr bootparamd 8 .
255.It Va WITHOUT_BOOTPD
256Do not build or install
257.Xr bootpd 8 .
258.It Va WITH_BRANCH_PROTECTION
259Build with branch protection enabled.
260On arm64 enable the use of pointer authentication and
261branch target identification instructions on arm64.
262These can be used to help mitigate some exploit techniques.
263.It Va WITHOUT_BSDINSTALL
264Do not build
265.Xr bsdinstall 8 ,
266.Xr sade 8 ,
267and related programs.
268.It Va WITHOUT_BSD_CPIO
269Do not build the BSD licensed version of cpio based on
270.Xr libarchive 3 .
271.It Va WITHOUT_BSNMP
272Do not build or install
273.Xr bsnmpd 1
274and related libraries and data files.
275.It Va WITHOUT_BZIP2
276Do not build contributed bzip2 software as a part of the base system.
277.Bf -symbolic
278The option has no effect yet.
279.Ef
280When set, these options are also in effect:
281.Pp
282.Bl -inset -compact
283.It Va WITHOUT_BZIP2_SUPPORT
284(unless
285.Va WITH_BZIP2_SUPPORT
286is set explicitly)
287.El
288.It Va WITHOUT_BZIP2_SUPPORT
289Build some programs without optional bzip2 support.
290.It Va WITHOUT_CALENDAR
291Do not build
292.Xr calendar 1 .
293.It Va WITHOUT_CAROOT
294Do not add the trusted certificates from the Mozilla NSS bundle to
295base.
296.It Va WITHOUT_CASPER
297This option has no effect.
298.It Va WITH_CCACHE_BUILD
299Use
300.Xr ccache 1
301for the build.
302No configuration is required except to install the
303.Sy devel/ccache
304or
305.Sy devel/sccache
306package.
307When using with
308.Xr distcc 1 ,
309set
310.Sy CCACHE_PREFIX=/usr/local/bin/distcc .
311When using with sccache
312set
313.Sy CCACHE_NAME=sccache
314in
315.Xr src.conf 5 .
316The default cache directory of
317.Pa $HOME/.ccache
318will be used, which can be overridden by setting
319.Sy CCACHE_DIR .
320The
321.Sy CCACHE_COMPILERCHECK
322option defaults to
323.Sy content
324when using the in-tree bootstrap compiler,
325and
326.Sy mtime
327when using an external compiler.
328The
329.Sy CCACHE_CPP2
330option is used for Clang but not GCC.
331.Pp
332Sharing a cache between multiple work directories requires using a layout
333similar to
334.Pa /some/prefix/src
335.Pa /some/prefix/obj
336and an environment such as:
337.Bd -literal -offset indent
338CCACHE_BASEDIR='${SRCTOP:H}' MAKEOBJDIRPREFIX='${SRCTOP:H}/obj'
339.Ed
340.Pp
341See

345Do not build
346.Xr geom_ccd 4
347and related utilities.
348.It Va WITHOUT_CDDL
349Do not build code licensed under Sun's CDDL.

402.El
403.It Va WITHOUT_CLANG_BOOTSTRAP
404Do not build the Clang C/C++ compiler during the bootstrap phase of
405the build.
406To be able to build the system, either gcc or clang bootstrap must be
407enabled unless an alternate compiler is provided via XCC.
408.It Va WITH_CLANG_EXTRAS
409Build additional clang and llvm tools, such as bugpoint and
410clang-format.
411.It Va WITH_CLANG_FORMAT
412Build clang-format.
413.It Va WITHOUT_CLANG_FULL
414Avoid building the ARCMigrate, Rewriter and StaticAnalyzer components of
415the Clang C/C++ compiler.
416.It Va WITH_CLEAN
417Clean before building world and/or kernel.
418Note that recording a new epoch in
419.Pa .clean_build_epoch
420in the root of the source tree will also force a clean world build.
421.It Va WITHOUT_CPP
422Do not build
423.Xr cpp 1 .
424.It Va WITHOUT_CROSS_COMPILER
425Do not build any cross compiler in the cross-tools stage of buildworld.
426When compiling a different version of
427.Fx
428than what is installed on the system, provide an alternate
429compiler with XCC to ensure success.
430When compiling with an identical version of
431.Fx
432to the host, this option may be safely used.
433This option may also be safe when the host version of
434.Fx
435is close to the sources being built, but all bets are off if there have
436been any changes to the toolchain between the versions.
437When set, it enforces these options:

488.It Va WITH_CTF
489Compile with CTF (Compact C Type Format) data.
490CTF data encapsulates a reduced form of debugging information
491similar to DWARF and the venerable stabs and is required for DTrace.
492.It Va WITHOUT_CUSE
493Do not build CUSE-related programs and libraries.
494.It Va WITHOUT_CXGBETOOL

518.It Va WITHOUT_DICT
519Do not build the Webster dictionary files.
520.It Va WITH_DIRDEPS_BUILD
521This is an alternate build system.
522For details see
523https://www.crufty.net/sjg/docs/freebsd-meta-mode.htm.
524Build commands can be seen from the top-level with:
525.Dl make show-valid-targets
526The build is driven by dirdeps.mk using
527.Va DIRDEPS
528stored in
529Makefile.depend files found in each directory.
530.Pp
531The build can be started from anywhere, and behaves the same.
532The initial instance of
533.Xr make 1
534recursively reads
535.Va DIRDEPS
536from
537.Pa Makefile.depend ,
538computing a graph of tree dependencies from the current origin.
539Setting
540.Va NO_DIRDEPS
541skips checking dirdep dependencies and will only build in the current
542and child directories.
543.Va NO_DIRDEPS_BELOW
544skips building any dirdeps and only build the current directory.
545.Pp
546This also utilizes the
547.Va WITH_META_MODE
548logic for incremental builds.
549.Pp
550The build hides commands executed unless
551.Va NO_SILENT
552is defined.
553.Pp
554Note that there is currently no mass install feature for this.
555This build is designed for producing packages, that can then be installed
556on a target system.
557.Pp
558The implementation in
559.Fx
560is incomplete.
561Completion would require leaf directories for building each kernel
562and package so that their dependencies can be tracked.

635with address and undefined behavior sanitizers.
636Requires that Clang be used as the base system compiler
637and that the runtime support library is available.
638.It Va WITH_DTRACE_TESTS
639Build and install the DTrace test suite in
640.Pa /usr/tests/cddl/usr.sbin/dtrace .
641This test suite is considered experimental on architectures other than

1851which triggers warnings in environments that differ from the
1852original developer.
1853.It Va WITHOUT_WERROR
1854Set this to not treat compiler warnings as errors.
1855Useful as a temporary workaround when working on fixing compiler warnings.
1856When set, warnings are still printed in the build log but do not fail the build.
1857.It Va WITHOUT_WIRELESS
1858Do not build programs used for 802.11 wireless networks; especially
1859.Xr wpa_supplicant 8
1860and
1861.Xr hostapd 8 .
1862When set, these options are also in effect:
1863.Pp
1864.Bl -inset -compact
1865.It Va WITHOUT_WIRELESS_SUPPORT
1866(unless
1867.Va WITH_WIRELESS_SUPPORT
1868is set explicitly)
1869.El
1870.It Va WITHOUT_WIRELESS_SUPPORT
1871Build libraries, programs, and kernel modules without
1872802.11 wireless support.
1873.It Va WITHOUT_WPA_SUPPLICANT_EAPOL
1874Build
1875.Xr wpa_supplicant 8
1876without support for the IEEE 802.1X protocol and without
1877support for EAP-PEAP, EAP-TLS, EAP-LEAP, and EAP-TTLS
1878protocols (usable only via 802.1X).
1879.It Va WITH_ZEROREGS
1880Build the basesystem with code to zero caller-used register contents
1881on function return.
1882This prevents leaking temporary values for side channel attacks.
1883Additionally this reduces the number of usable ROP gadgets for attackers.
1884.It Va WITHOUT_ZFS
1885Do not build the ZFS file system kernel module, libraries such as
1886.Xr libbe 3 ,
1887and user commands such as
1888.Xr zpool 8
1889or
1890.Xr zfs 8 .
1891Also disable ZFS support in utilities and libraries which implement
1892ZFS-specific functionality.
1893When set, it enforces these options:
1894.Pp
1895.Bl -item -compact
1896.It
1897.Va WITHOUT_ZFS_TESTS
1898.El
1899.It Va WITHOUT_ZFS_TESTS
1900Do not build and install the legacy ZFS test suite.
1901.It Va WITHOUT_ZONEINFO
1902Do not build the timezone database.
1903When set, it enforces these options:
1904.Pp
1905.Bl -item -compact
1906.It
1907.Va WITHOUT_ZONEINFO_LEAPSECONDS_SUPPORT
1908.El
1909.It Va WITH_ZONEINFO_LEAPSECONDS_SUPPORT
1910Build leapsecond information in to the timezone database.
1911This option violates
1912.St -p1003.1
1913and all other applicable standards, and is known to cause unexpected
1914issues with date/time handling in many applications and programming
1915languages.

1918The following options accept a single value from a list of valid values.
1919.Bl -tag -width indent
1920.It Va INIT_ALL
1921Control default initialization of stack variables in C and C++ code.
1922Options other than
1923.Li none
1924require the Clang compiler or GCC 12.0 or later.
1925The default value is
1926.Li none .
1927Valid values are:
1928.Bl -tag -width indent
1929.It Li none
1930Do not initialize stack variables (standard C/C++ behavior).
1931.It Li pattern
1932Build the base system or kernel with stack variables initialized to
1933.Pq compiler defined
1934debugging patterns on function entry.
1935.It Li zero
1936Build the base system or kernel with stack variables initialized
1937to zero on function entry.
1938This value is converted to
1939.Li none
1940for amd64 kernel builds due to incompatability with ifunc memset.
1941.El
1942.It Va LIBC_MALLOC
1943Specify the
1944.Xr malloc 3
1945implementation used by libc.
1946The default value is
1947.Li jemalloc .
1948Valid values are:
1949.Bl -tag -width indent
1950.It Li jemalloc
1951.El
1952.Pp
1953Other implementations are expected in the future in both
1954.Fx
1955and downstream consumers.
