6.Sh NAME
7.Nm src.conf
8.Nd "source build options"
9.Sh DESCRIPTION
10The
11.Nm
12file contains settings that will apply to every build involving 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 variables are ignored regardless of their setting;
82even if they would be set to
83.Dq Li FALSE
84or
85.Dq Li NO .
86The presence of an option causes
87it to be honored by
88.Xr make 1 .
89.Pp
90This list provides a name and short description for variables
91that can be used for source builds.

153of the normal system build.
154The resulting system cannot build programs from source.

428to the host, this option may be safely used.
429This option may also be safe when the host version of

535This is an experimental build system.
536For details see
537http://www.crufty.net/sjg/docs/freebsd-meta-mode.htm.
538Build commands can be seen from the top-level with:
539.Dl make show-valid-targets
540The build is driven by dirdeps.mk using
541.Va DIRDEPS
542stored in
543Makefile.depend files found in each directory.
544.Pp
545The build can be started from anywhere, and behaves the same.
546The initial instance of
547.Xr make 1
548recursively reads
549.Va DIRDEPS
550from
551.Pa Makefile.depend ,
552computing a graph of tree dependencies from the current origin.
553Setting
554.Va NO_DIRDEPS
555skips checking dirdep dependencies and will only build in the current
556and child directories.
557.Va NO_DIRDEPS_BELOW
558skips building any dirdeps and only build the current directory.
559.Pp
560This also utilizes the
561.Va WITH_META_MODE
562logic for incremental builds.
563.Pp
564The build hides commands executed unless
565.Va NO_SILENT
566is defined.
