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
97.It Va WITHOUT_ACCT
98Do not build process accounting tools such as
99.Xr accton 8
100and
101.Xr sa 8 .
102.It Va WITHOUT_ACPI
103Do not build
104.Xr acpiconf 8 ,
105.Xr acpidump 8
106and related programs.
107.It Va WITHOUT_APM
108Do not build
109.Xr apm 8 ,
110.Xr apmd 8
111and related programs.
112.It Va WITH_ASAN
113Build the base system with Address Sanitizer (ASan) to detect
114memory corruption bugs such as buffer overflows or use-after-free.
115Requires that Clang be used as the base system compiler
116and that the runtime support library is available.
117When set, it enforces these options:
118.Pp
119.Bl -item -compact
120.It
121.Va WITH_LLVM_BINUTILS
122.It
123.Va WITH_LLVM_CXXFILT
124.El
125.It Va WITHOUT_ASSERT_DEBUG
126Compile programs and libraries without the
127.Xr assert 3
128checks.
129.It Va WITHOUT_AT
130Do not build
131.Xr at 1
132and related utilities.
133.It Va WITHOUT_AUDIT
134Do not build audit support into system programs.
135.It Va WITHOUT_AUTHPF
136Do not build
137.Xr authpf 8 .
138.It Va WITHOUT_AUTOFS
139Do not build
140.Xr autofs 4
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.
154For details see
155.Lk https://www.BearSSL.org/
156.Pp
157This library is currently only used to perform
158signature verification and related operations
159for Verified Exec and
160.Xr loader 8 .
161.Pp
162Due to size constraints in the BIOS environment on x86, one may need to set
163.Va LOADERSIZE
164larger than the
165default 500000, although often loader is under the 500k limit even with
166this option.
167Setting
168.Va LOADERSIZE
169larger than 500000 may cause
170.Xr pxeboot 8
171to be too large to work.
172Careful testing of the loader in the target environment when built with a larger
173limit to establish safe limits is critical because different BIOS environments
174reserve differing amounts of the low 640k space, making a precise limit for
175everybody impossible.
176.Pp
177See also
178.Va WITH_LOADER_PXEBOOT
179for other considerations.
180When set, these options are also in effect:
181.Pp
182.Bl -inset -compact
183.It Va WITH_LOADER_EFI_SECUREBOOT
184(unless
185.Va WITHOUT_LOADER_EFI_SECUREBOOT
186is set explicitly)

188(unless
189.Va WITHOUT_LOADER_VERIEXEC
190is set explicitly)
191.It Va WITH_LOADER_VERIEXEC_VECTX

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

393.El
394.It Va WITHOUT_CLANG_BOOTSTRAP
395Do not build the Clang C/C++ compiler during the bootstrap phase of
396the build.
397To be able to build the system, either gcc or clang bootstrap must be
398enabled unless an alternate compiler is provided via XCC.
399.It Va WITH_CLANG_EXTRAS
400Build additional clang and llvm tools, such as bugpoint and
401clang-format.
402.It Va WITH_CLANG_FORMAT
403Build clang-format.

408Clean before building world and/or kernel.
409.It Va WITHOUT_CPP
410Do not build
411.Xr cpp 1 .
412.It Va WITHOUT_CROSS_COMPILER
413Do not build any cross compiler in the cross-tools stage of buildworld.
414When compiling a different version of
415.Fx
416than what is installed on the system, provide an alternate
417compiler with XCC to ensure success.
418When compiling with an identical version of
419.Fx
420to the host, this option may be safely used.
421This option may also be safe when the host version of
422.Fx
423is close to the sources being built, but all bets are off if there have
424been any changes to the toolchain between the versions.
425When set, it enforces these options:

476.It Va WITH_CTF
477Compile with CTF (Compact C Type Format) data.
478CTF data encapsulates a reduced form of debugging information
479similar to DWARF and the venerable stabs and is required for DTrace.
480.It Va WITHOUT_CUSE

506.It Va WITHOUT_DICT
507Do not build the Webster dictionary files.
508.It Va WITH_DIRDEPS_BUILD
509This is an alternate build system.
510For details see
511https://www.crufty.net/sjg/docs/freebsd-meta-mode.htm.
512Build commands can be seen from the top-level with:
513.Dl make show-valid-targets
514The build is driven by dirdeps.mk using
515.Va DIRDEPS
516stored in
517Makefile.depend files found in each directory.
518.Pp
519The build can be started from anywhere, and behaves the same.
520The initial instance of
521.Xr make 1
522recursively reads
523.Va DIRDEPS
524from
525.Pa Makefile.depend ,
526computing a graph of tree dependencies from the current origin.
527Setting
528.Va NO_DIRDEPS
529skips checking dirdep dependencies and will only build in the current
530and child directories.
531.Va NO_DIRDEPS_BELOW
532skips building any dirdeps and only build the current directory.
533.Pp
534This also utilizes the
535.Va WITH_META_MODE
536logic for incremental builds.
537.Pp
538The build hides commands executed unless
539.Va NO_SILENT
540is defined.
541.Pp
542Note that there is currently no mass install feature for this.
543This build is designed for producing packages, that can then be installed
544on a target system.
545.Pp
546The implementation in
547.Fx
548is incomplete.
549Completion would require leaf directories for building each kernel
550and package so that their dependencies can be tracked.

1839Useful as a temporary workaround when code enters the tree
1840which triggers warnings in environments that differ from the
1841original developer.
1842.It Va WITHOUT_WERROR
1843Set this to not treat compiler warnings as errors.
1844Useful as a temporary workaround when working on fixing compiler warnings.
1845When set, warnings are still printed in the build log but do not fail the build.
1846.It Va WITHOUT_WIRELESS
1847Do not build programs used for 802.11 wireless networks; especially
1848.Xr wpa_supplicant 8
1849and
1850.Xr hostapd 8 .
1851When set, these options are also in effect:
1852.Pp
1853.Bl -inset -compact
1854.It Va WITHOUT_WIRELESS_SUPPORT
1855(unless
1856.Va WITH_WIRELESS_SUPPORT
1857is set explicitly)
1858.El
1859.It Va WITHOUT_WIRELESS_SUPPORT
1860Build libraries, programs, and kernel modules without
1861802.11 wireless support.
1862.It Va WITHOUT_WPA_SUPPLICANT_EAPOL
1863Build
1864.Xr wpa_supplicant 8
1865without support for the IEEE 802.1X protocol and without
1866support for EAP-PEAP, EAP-TLS, EAP-LEAP, and EAP-TTLS
1867protocols (usable only via 802.1X).
1868.It Va WITHOUT_ZFS
1869Do not build the ZFS file system kernel module, libraries such as
1870.Xr libbe 3 ,
1871and user commands such as
1872.Xr zpool 8
1873or
1874.Xr zfs 8 .
1875Also disable ZFS support in utilities and libraries which implement
1876ZFS-specific functionality.
1877When set, it enforces these options:
1878.Pp
1879.Bl -item -compact
1880.It
1881.Va WITHOUT_ZFS_TESTS
1882.El
1883.It Va WITHOUT_ZFS_TESTS
1884Do not build and install the legacy ZFS test suite.
1885.It Va WITHOUT_ZONEINFO
1886Do not build the timezone database.
1887When set, it enforces these options:
1888.Pp
1889.Bl -item -compact
1890.It
1891.Va WITHOUT_ZONEINFO_LEAPSECONDS_SUPPORT
1892.El
1893.It Va WITH_ZONEINFO_LEAPSECONDS_SUPPORT
1894Build leapsecond information in to the timezone database.
1895.El
1896.Pp
1897The following options accept a single value from a list of valid values.
1898.Bl -tag -width indent
1899.It Va INIT_ALL
1900Control default initialization of stack variables in C and C++ code.
1901Options other than
1902.Li none
1903require the Clang compiler or GCC 12.0 or later.
1904The default value is
1905.Li none .
1906Valid values are:
1907.Bl -tag -width indent
1908.It Li none
1909Do not initialize stack variables (standard C/C++ behavior).
1910.It Li pattern
1911Build the base system or kernel with stack variables initialized to
1912.Pq compiler defined
1913debugging patterns on function entry.
1914.It Li zero
1915Build the base system or kernel with stack variables initialized
1916to zero on function entry.
1917This value is converted to
1918.Li none
1919for amd64 kernel builds due to incompatability with ifunc memset.
1920.El
1921.It Va LIBC_MALLOC
1922Specify the
1923.Xr malloc 3
1924implementation used by libc.
1925The default value is
1926.Li jemalloc .
1927Valid values are:
1928.Bl -tag -width indent
1929.It Li jemalloc
1930.El
1931.Pp
1932Other implementations are expected in the future in both
1933.Fx
1934and downstream consumers.
