29 .Dt MAKE.CONF 5
30 .Os
31 .Sh NAME
32 .Nm make.conf
33 .Nd system build information
34 .Sh DESCRIPTION
35 The file
36 .Nm
37 contains settings that control the compilation of the
38 .Dx
39 sources.
40 The file
41 .Nm
42 is generally created by the system administrator when the values need
43 to be changed from their defaults.
44 .Pp
45 The purpose of
46 .Nm
47 is not to run commands or perform compilation actions
48 directly.
49 Instead, it is included by the various makefiles in
50 .Pa /usr/src
51 which conditionalize their internal actions according to the settings
52 found there.
53 .Pp
54 The
55 .Pa /etc/make.conf
56 file is included from the appropriate
57 .Pa Makefile
58 which specifies the default settings for all the available options.
59 Options need only be specified in
60 .Pa /etc/make.conf
61 when the system administrator wishes to override these defaults.
62 .Pp
63 The build procedures occur in three areas: world, kernel, and
64 documentation.
65 Variables set in
66 .Nm
67 may be applicable during builds in one, two, or all of these areas.
68 They may be specified for a particular build via the
69 .Fl D
70 option of
71 .Xr make 1 .
72 .Pp
73 The following lists provide a name and short description for each
74 variable you can use during the indicated builds.
75 The values of variables flagged as
76 .Vt bool
77 are ignored; the variable being set at all (even to
78 .Dq Li FALSE
79 or
80 .Dq Li NO )
81 causes it to be treated as if it were set.
82 .Pp
83 The following list provides a name and short description for variables
84 that are used for all builds, or are used by the
85 .Pa makefiles
86 for things other than builds.
87 .Bl -tag -width Ar
88 .It Va CPUTYPE
89 .Pq Vt str
90 Controls which processor should be targeted for generated code.
91 This controls processor-specific optimizations in certain code
92 (currently only OpenSSL) as well as modifying the value of
93 .Va CFLAGS
94 and
95 .Va COPTFLAGS
96 to contain the appropriate optimization directive to
97 .Xr gcc 1 .
98 The automatic setting of
99 .Va CFLAGS
100 and
101 .Va COPTFLAGS
102 may be overridden using the
103 .Va NO_CPU_CFLAGS
104 and
105 .Va NO_CPU_COPTFLAGS
106 variables, respectively. Refer to
107 .Pa /usr/share/examples/etc/defaults/make.conf
108 for a list of recognized
109 .Va CPUTYPE
110 options.
111 .It Va CCVER
112 .Pq Vt str
113 Controls which GCC version to use by default. It should be set as
114 CCVER?= so as not to interfere with overrides from userland. We
115 currently recommend that an override NOT be set in
116 .Pa /etc/make.conf .
117 Currently accepted values are
118 .Dq gcc34
119 and
120 .Dq gcc41
121 (experimental).
122 .It Va CFLAGS
123 .Pq Vt str
124 Controls the compiler setting when compiling C code.
125 Optimization levels above
126 .Fl O
127 .Pq Fl O2 , No ...
128 are not supported.
129 .Va BDECFLAGS
130 is provided as a set of
131 .Xr gcc 1
132 settings suggested by
133 .An "Bruce Evans" Aq bde@FreeBSD.org
134 for developing and testing changes.
135 They can be used, if set, by:
136 .Pp
137 .Bd -literal -offset indent
138 CFLAGS+=${BDECFLAGS}
139 .Ed
140 .It Va NO_CPU_CFLAGS
141 .Pq Vt str
142 Setting this variable will prevent CPU specific compiler flags
143 from being automatically added to
144 .Va CFLAGS
145 during compile time.
146 .It Va CXXFLAGS
147 .Pq Vt str
148 Controls the compiler settings when compiling C++ code.
149 .Va CXXFLAGS
150 is initially set to the value of
151 .Va CFLAGS .
152 If you want to add to the
153 .Va CXXFLAGS
154 value, use
155 .Dq Li +=
156 instead of
157 .Dq Li = .
158 .It Va INSTALL
159 .Pq Vt str
160 the default install command.
161 To have components compared before doing the install, use
162 .Bd -literal -offset indent
163 INSTALL="install -C"
164 .Ed
165 .It Va LOCAL_DIRS
166 .Pq Vt str
167 List any directories that should be entered when running make

173 .Xr make 1
174 to process the command scripts in makefiles.
175 .Xr sh 1 ,
176 .Xr ksh 1 ,
177 and
178 .Xr csh 1
179 all currently supported.
180 .Bd -literal -offset indent
181 MAKE_SHELL?=sh
182 .Ed
183 .It Va MODULES_OVERRIDE
184 .Pq Vt str
185 Set to a list of modules to build instead of all of them.
186 .It Va MTREE_FOLLOWS_SYMLINKS
187 .Pq Vt str
188 Set this to
189 .Dq Fl L
190 to cause
191 .Xr mtree 8
192 to follow symlinks.
193 .It Va NO_DOCUPDATE
194 .Pq Vt bool
195 Set this to not update the doc tree during
196 .Dq Li "make update" .
197 .It Va STRIP
198 .Pq Vt str
199 Set this to the flag to pass the
200 .Xr strip 1
201 command.
202 If set to a blank value, components will be installed with debugging
203 symbols.
204 .It Va SUP_UPDATE
205 .Pq Vt bool
206 Set this to use
207 .Xr cvsup 1
208 to update your ports with
209 .Dq Li "make update" .
210 .It Va SUP

213 .Xr cvsup 1
214 command for
215 .Dq Li "make update" .

217 .Pq Vt str
218 The flag for the
219 .Xr sup 1
220 command when doing
221 .Dq Li "make update" .
222 This defaults to
223 .Dq Fl g L Ar 2 .
224 .It Va SUPHOST
225 .Pq Vt str
226 The hostname of the sup server to use when doing
227 .Dq Li "make update" .
228 .It Va SUPFILE
229 .Pq Vt str
230 The first
231 .Ar supfile
232 to use when doing a
233 .Dq Li "make update" .
234 This defaults to
235 .Pa /usr/share/examples/cvsup/standard\-supfile .
236 .It Va SUPFILE1
237 .Pq Vt str
238 The second
239 .Ar supfile
240 to use when doing a
241 .Dq Li "make update" .
242 This defaults to
243 .Pa /usr/share/examples/cvsup/secure\-supfile .
244 .It Va SUPFILE2
245 .Pq Vt str
246 The third
247 .Ar supfile
248 to use when doing a
249 .Dq Li "make update" .
250 This defaults to
251 .Pa /usr/share/examples/cvsup/secure\-supfile .
252 .It Va DOCSUPFILE
253 .Pq Vt str
254 The documentation
255 .Ar supfile

260 .It Va WARNS_WERROR
261 Causes
262 .Fl Werror
263 to be added to
264 .Va CFLAGS
265 when WARNS is in effect.
266 .El
267 .Pp
268 The following list provides a name and short description for variables
269 that are only used doing a kernel build:
270 .Bl -tag -width Ar
271 .It Va BOOT_COMCONSOLE_PORT
272 .Pq Vt str
273 The port address to use for the console if the boot blocks have
274 been configured to use a serial console instead of the keyboard/video card.
275 .It Va BOOT_COMCONSOLE_SPEED
276 .Pq Vt int
277 The baud rate to use for the console if the boot blocks have
278 been configured to use a serial console instead of the keyboard/video card.
279 .It Va COPTFLAGS
280 .Pq Vt str
281 Controls the compiler settings when building the
282 kernel.
283 Optimization levels above

285 .Pq Fl O2 , No ...
286 are not guaranteed to work.
287 .It Va KERNCONF
288 .Pq Vt str
289 Controls which kernel configurations will be
290 built by
291 .Dq Li "${MAKE} buildkernel"
292 and installed by

294 For example,
295 .Bd -literal -offset indent
296 KERNCONF=MINE DEBUG GENERIC OTHERMACHINE
297 .Ed
298 .Pp
299 will build the kernels specified by the config files
300 .Pa MINE , DEBUG , GENERIC ,
301 and
302 .Pa OTHERMACHINE ,
303 and install the kernel specified by the config file
304 .Pa MINE .
305 It defaults to
306 .Pa GENERIC .
307 .It Va LOADER_TFTP_SUPPORT
308 .Pq Vt bool
309 While not a buildkernel-affected option, there is no better place for this.
310 By default the
311 .Xr pxeboot 8
312 loader retrieves the kernel via NFS.
313 Defining this and recompiling
314 .Pa /usr/src/sys/boot
315 will cause it to retrieve the kernel via TFTP.
316 This allows pxeboot to load a custom BOOTP diskless kernel yet
317 still mount the server's
318 .Pa /
319 rather than load the server's kernel.
320 .It Va NO_CPU_COPTFLAGS
321 .Pq Vt str
322 Setting this variable will prevent CPU specific compiler flags
323 from being automatically added to
324 .Va COPTFLAGS
325 during compile time.

327 .Pq Vt bool
328 Set this to skip the clean target when using

331 .Pq Vt bool
332 Set this to skip running
333 .Xr config 8
334 during
335 .Dq Li "${MAKE} buildkernel" .
336 .It Va NO_KERNELDEPEND
337 .Pq Vt bool
338 Set this to skip running
339 .Dq Li "${MAKE} depend"
340 during
341 .Dq Li "${MAKE} buildkernel" .
342 .It Va NO_MODULES
343 .Pq Vt bool
344 Set to not build modules with the kernel.
345 .El
346 .Pp
347 The following list provides a name and short description for variables
348 that are used during the world build:
349 .Bl -tag -width Ar
350 .It Va ENABLE_SUID_K5SU
351 .Pq Vt bool
352 Set this if you wish to use the k5su utility.
353 Otherwise, it will be installed without the set-user-ID bit set.
354 This is only relevant if
355 .Va WANT_KERBEROS
356 is defined.
357 .It Va ENABLE_SUID_SSH
358 .Pq Vt bool
359 Set this to install
360 .Xr ssh 1

419 .Pq Vt bool
420 Set to not build OpenSSH.
421 .It Va NO_OPENSSL
422 .Pq Vt bool

474 .It Va SENDMAIL_MC
475 .Pq Vt str
476 The default

479 The value should include the full path to the
480 .Pa .mc
481 file, e.g.,
482 .Pa /etc/mail/myconfig.mc .
483 Use with caution as a make install will overwrite any existing

487 is now deprecated.
488 .It Va SENDMAIL_SUBMIT_MC
