Refer to 106.Pa /usr/share/examples/etc/defaults/make.conf 107for a list of recognized 108.Va CPUTYPE 109options. 110.It Va CCVER 111.Pq Vt str 112Controls which GCC version to use by default. 113It should be set as 114.Li CCVER?= 115so as not to interfere with overrides from userland. 116We currently recommend that an override NOT be set in 117.Pa /etc/make.conf . 118Currently accepted values for compilers which are part of 119.Dx 120are 121.Dq gcc41 122and 123.Dq gcc44 124(default). 125All other values will handled according to the settings in 126.Xr compilers.conf 5 . 127.It Va BINUTILSVER 128.Pq Vt str 129Controls which binutils to use by default. 130Currently accepted values are 131.Dq binutils221 132(default). 133.It Va CFLAGS 134.Pq Vt str 135Controls the compiler setting when compiling C code. 136Optimization levels above 137.Fl O 138.Pq Fl O2 , No ... 139are not supported. 140.Va BDECFLAGS 141is provided as a set of 142.Xr gcc 1 143settings suggested by

151.Pq Vt str 152Similar to 153.Va CFLAGS 154but it will cause 155.Va STRIP 156to be set to a blank value, if set. 157Typically, 158.Va DEBUG_FLAGS 159is set to 160.Fl g 161for compiling with debug symbols. 162.It Va NO_CPU_CFLAGS 163.Pq Vt str 164Setting this variable will prevent CPU specific compiler flags 165from being automatically added to 166.Va CFLAGS 167during compile time. 168.It Va CXXFLAGS 169.Pq Vt str 170Controls the compiler settings when compiling C++ code. 171.Va CXXFLAGS 172is initially set to the value of 173.Va CFLAGS . 174If you want to add to the 175.Va CXXFLAGS 176value, use 177.Dq Li += 178instead of 179.Dq Li = . 180.It Va INSTALL 181.Pq Vt str 182the default install command. 183To have components compared before doing the install, use 184.Bd -literal

MAKE_SHELL 193.Pq Vt str 194Controls the shell used internally by 195.Xr make 1 196to process the command scripts in makefiles. 197.Xr sh 1 , 198.Xr ksh 1 , 199and 200.Xr csh 1 201all currently supported. 202.Bd -literal -offset indent 203MAKE_SHELL?=sh 204.Ed 205.It Va MODULES_OVERRIDE 206.Pq Vt str 207Set to a list of modules to build instead of all of them. 208.It Va MTREE_FOLLOWS_SYMLINKS 209.Pq Vt str 210Set this to 211.Dq Fl L 212to cause 213.Xr mtree 8 214to follow symlinks. 215.It Va STRIP 216.Pq Vt str 217Set this to the flag to pass to the 218.Xr strip 1 219command. 220If set to a blank value, debug symbols will not be removed. 221.Va STRIP 222is automatically set to a blank value if 223.Va DEBUG_FLAGS 224is set. 225.It Va WANT_HESIOD 226.Pq Vt bool 227Set this to build 228.Xr hesiod 3 229support into libc. 230.It Va NO_NS_CACHING 231.Pq Vt bool 232Set this to disable name caching in the nsswitch subsystem. 233The generic caching daemon, 234.Xr nscd 8 , 235will not be built either if this option is set. 236.It Va NO_WERROR 237Set this if you don't want 238.Fl Werror 239to be added to 240.Va CWARNFLAGS 241or used in the kernel build. 242.It Va STATIC_LOCALES 243.Pq Vt str 244Set to a list of locales to build into statically-linked binaries. 245Currently supported locales are: BIG5 EUC EUCTW ISO2022 MSKanji UTF8 246.El 247.Pp 248The following list provides a name and short description for variables 249that are only used doing a kernel build: 250.Bl -tag -width Ar 251.It Va BOOT_COMCONSOLE_PORT 252.Pq Vt str 253The port address to use for the console if the boot blocks have 254been configured to use a serial console instead of the keyboard/video card. 255.It Va BOOT_COMCONSOLE_SPEED 256.Pq Vt int 257The baud rate to use for the console if the boot blocks have 258been configured to use a serial console instead of the keyboard/video card. 259.It Va COPTFLAGS 260.Pq Vt str 261Controls the compiler settings when building the 262kernel. 263Optimization levels above 264.Fl O 265.Pq Fl O2 , No ... 266are not guaranteed to work. 267.It Va KERNCONF 268.Pq Vt str 269Controls which kernel configurations will be 270built by 271.Dq Li "${MAKE} buildkernel" 272and installed by 273.Dq Li "${MAKE} installkernel" . 274For example, 275.Bd -literal -offset indent 276KERNCONF=MINE DEBUG GENERIC OTHERMACHINE 277.Ed 278.Pp 279will build the kernels specified by the config files 280.Pa MINE , DEBUG , GENERIC , 281and 282.Pa OTHERMACHINE , 283and install the kernel specified by the config file 284.Pa MINE . 285It defaults to 286.Pa GENERIC . 287.It Va LOADER_TFTP_SUPPORT 288.Pq Vt bool 289While not a buildkernel-affected option, there is no better place for this. 290By default the 291.Xr pxeboot 8 292loader retrieves the kernel via NFS. 293Defining this and recompiling 294.Pa /usr/src/sys/boot 295will cause it to retrieve the kernel via TFTP. 296This allows pxeboot to load a custom BOOTP diskless kernel yet 297still mount the server's 298.Pa / 299rather than load the server's kernel. 300.It Va NO_CPU_COPTFLAGS 301.Pq Vt str 302Setting this variable will prevent CPU specific compiler flags 303from being automatically added to 304.Va COPTFLAGS 305during compile time. 306.It Va NO_KERNELCLEAN 307.Pq Vt bool 308Set this to skip the clean target when using 309.Dq Li "${MAKE} buildkernel" . 310.It Va

"${MAKE} depend" 320during 321.Dq Li "${MAKE} buildkernel" . 322.It Va NO_KERNEL_OLD_STRIP 323.Pq Vt bool 324Set this to skip stripping debugging symbols from old kernel and modules 325(kernel.old, modules.old) during 326.Dq Li "${MAKE} installkernel" . 327.It Va NO_MODULES 328.Pq Vt bool 329Set to not build modules with the kernel. 330.El 331.Pp 332The following list provides a name and short description for variables 333that are used during the world build: 334.Bl -tag -width Ar 335.It Va ENABLE_SUID_SSH 336.Pq Vt bool 337Set this to install 338.Xr ssh 1 339with the setuid bit turned on. 340.It Va MODULES_WITH_WORLD 341.Pq Vt bool 342Set to build modules with the system instead of the kernel. 343.It Va NO_CRYPT 344.Pq Vt bool 345Set to not build crypto code. 346.It Va NO_CVS 347.Pq Vt

to not build OpenSSL (implies 387.Va NO_OPENSSH ) . 388.It Va NO_SENDMAIL 389.Pq Vt bool 390Set to not build 391.Xr sendmail 8 392and related programs. 393.It Va NO_SHARE 394.Pq Vt bool 395Set to not enter the share subdirectory. 396.It Va NO_X 397.Pq Vt bool 398Set to not compile in X\-Windows support (e.g.\& 399.Xr doscmd 1 ) . 400.It Va NOCLEAN 401.Pq Vt bool 402Set this to disable cleaning

Li "${MAKE} cleandir" . 411.It Va NOFSCHG 412.Pq Vt bool 413Set to not install certain components with flag schg. 414This is useful in a jailed environment. 415.It Va NOINFO 416.Pq Vt bool 417Set to not make or install 418.Xr info 5 419files. 420.It Va NOINFOCOMPRESS 421.Pq Vt bool 422Set to not compress the info pages. 423.It Va NOMAN 424.Pq Vt bool 425Set to not build manual pages 426.It Va NOMANCOMPRESS 427.Pq Vt bool 428Set to not compress the manual pages. 429.It Va NOPROFILE 430.Pq Vt bool 431Set to avoid compiling profiled libraries. 432.It Va PPP_NOSUID 433.Pq Vt bool 434Set to disable the installation of 435.Xr ppp 8 436with the set-user-ID bit on. 437.It Va SENDMAIL_MC 438.Pq Vt str 439The default 440.Xr m4 1 441configuration file to use at install time. 442The value should include the full path to the 443.Pa .mc 444file, e.g., 445.Pa /etc/mail/myconfig.mc . 446Use with caution as a make install will overwrite any existing 447.Pa /etc/mail/sendmail.cf . 448Note
