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 binutils220 132and 133.Dq binutils221 134(default). 135.It Va CFLAGS 136.Pq Vt str 137Controls the compiler setting when compiling C code. 138Optimization levels above 139.Fl O 140.Pq Fl O2 , No ... 141are not supported. 142.Va BDECFLAGS 143is provided as a set of 144.Xr gcc 1

152.It Va DEBUG_FLAGS 153.Pq Vt str 154Similar to 155.Va CFLAGS 156but it will cause 157.Va STRIP 158to be set to a blank value, if set. 159Typically, 160.Va DEBUG_FLAGS 161is set to 162.Fl g 163for compiling with debug symbols. 164.It Va NO_CPU_CFLAGS 165.Pq Vt str 166Setting this variable will prevent CPU specific compiler flags 167from being automatically added to 168.Va CFLAGS 169during compile time. 170.It Va CXXFLAGS 171.Pq Vt str 172Controls the compiler settings when compiling C++ code. 173.Va CXXFLAGS 174is initially set to the value of 175.Va CFLAGS . 176If you want to add to

194.It Va MAKE_SHELL 195.Pq Vt str 196Controls the shell used internally by 197.Xr make 1 198to process the command scripts in makefiles. 199.Xr sh 1 , 200.Xr ksh 1 , 201and 202.Xr csh 1 203all currently supported. 204.Bd -literal -offset indent 205MAKE_SHELL?=sh 206.Ed 207.It Va MODULES_OVERRIDE 208.Pq Vt str 209Set to a list of modules to build instead of all of them. 210.It Va MTREE_FOLLOWS_SYMLINKS 211.Pq Vt str 212Set this to 213.Dq Fl L 214to cause 215.Xr mtree 8 216to follow symlinks. 217.It Va STRIP 218.Pq Vt str 219Set this to the flag to pass to the 220.Xr strip 1 221command. 222If set to a blank value, debug symbols will not be removed. 223.Va STRIP 224is automatically set to a blank value if 225.Va DEBUG_FLAGS 226is set. 227.It Va WANT_HESIOD 228.Pq Vt bool 229Set this to build 230.Xr hesiod 3 231support into libc. 232.It Va NO_NS_CACHING 233.Pq Vt bool 234Set this to disable name caching in the nsswitch subsystem. 235The generic caching daemon, 236.Xr nscd 8 , 237will not be built either if this option is set. 238.It Va NO_WERROR 239Set this if you don't want 240.Fl Werror 241to be added to 242.Va CWARNFLAGS 243or used in the kernel build. 244.It Va STATIC_LOCALES 245.Pq Vt str 246Set to a list of locales to build into statically-linked binaries. 247Currently supported locales are: BIG5 EUC EUCTW ISO2022 MSKanji UTF8 248.El 249.Pp 250The following list provides a name and short description for variables 251that are only used doing a kernel build: 252.Bl -tag -width Ar 253.It Va BOOT_COMCONSOLE_PORT 254.Pq Vt str 255The port address to use for the console if the boot blocks have 256been configured to use a serial console instead of the keyboard/video card. 257.It Va BOOT_COMCONSOLE_SPEED 258.Pq Vt int 259The baud rate to use for the console if the boot blocks have 260been configured to use a serial console instead of the keyboard/video card. 261.It Va COPTFLAGS 262.Pq Vt str 263Controls the compiler settings when building the 264kernel. 265Optimization levels above 266.Fl O 267.Pq Fl O2 , No ... 268are not guaranteed to work. 269.It Va KERNCONF 270.Pq Vt str 271Controls which kernel configurations will be 272built by 273.Dq Li "${MAKE} buildkernel" 274and installed by 275.Dq Li "${MAKE} installkernel" . 276For example, 277.Bd -literal -offset indent 278KERNCONF=MINE DEBUG GENERIC OTHERMACHINE 279.Ed 280.Pp 281will build the kernels specified by the config files 282.Pa MINE , DEBUG , GENERIC , 283and 284.Pa OTHERMACHINE , 285and install the kernel specified by the config file 286.Pa MINE . 287It defaults to 288.Pa GENERIC . 289.It Va LOADER_TFTP_SUPPORT 290.Pq Vt bool 291While not a buildkernel-affected option, there is no better place for this. 292By default the 293.Xr pxeboot 8 294loader retrieves the kernel via NFS. 295Defining this and recompiling 296.Pa /usr/src/sys/boot 297will cause it to retrieve the kernel via TFTP. 298This allows pxeboot to load a custom BOOTP diskless kernel yet 299still mount the server's 300.Pa / 301rather than load the server's kernel. 302.It Va NO_CPU_COPTFLAGS 303.Pq Vt str 304Setting this variable will prevent CPU specific compiler flags 305from being automatically added to 306.Va COPTFLAGS 307during compile time. 308.It Va NO_KERNELCLEAN 309.Pq Vt bool 310Set this to skip the clean target when using 311.Dq Li "${MAKE} buildkernel" . 312.It Va

"${MAKE} depend" 322during 323.Dq Li "${MAKE} buildkernel" . 324.It Va NO_KERNEL_OLD_STRIP 325.Pq Vt bool 326Set this to skip stripping debugging symbols from old kernel and modules 327(kernel.old, modules.old) during 328.Dq Li "${MAKE} installkernel" . 329.It Va NO_MODULES 330.Pq Vt bool 331Set to not build modules with the kernel. 332.El 333.Pp 334The following list provides a name and short description for variables 335that are used during the world build: 336.Bl -tag -width Ar 337.It Va ENABLE_SUID_SSH 338.Pq Vt bool 339Set this to install 340.Xr ssh 1 341with the setuid bit turned on. 342.It Va MODULES_WITH_WORLD 343.Pq Vt bool 344Set to build modules with the system instead of the kernel. 345.It Va NO_CRYPT 346.Pq Vt bool 347Set to not build crypto code. 348.It Va NO_CVS 349.Pq Vt

to not build OpenSSL (implies 389.Va NO_OPENSSH ) . 390.It Va NO_SENDMAIL 391.Pq Vt bool 392Set to not build 393.Xr sendmail 8 394and related programs. 395.It Va NO_SHARE 396.Pq Vt bool 397Set to not enter the share subdirectory. 398.It Va NO_X 399.Pq Vt bool 400Set to not compile in X\-Windows support (e.g.\& 401.Xr doscmd 1 ) . 402.It Va NOCLEAN 403.Pq Vt bool 404Set this to disable cleaning

NOMANCOMPRESS 429.Pq Vt bool 430Set to not compress the manual pages. 431.It Va NOPROFILE 432.Pq Vt bool 433Set to avoid compiling profiled libraries. 434.It Va PPP_NOSUID 435.Pq Vt bool 436Set to disable the installation of 437.Xr ppp 8 438with the set-user-ID bit on. 439.It Va SENDMAIL_MC 440.Pq Vt str 441The default 442.Xr m4 1 443configuration file to use at install time. 444The value should include the full path to the 445.Pa .mc 446file, e.g., 447.Pa /etc/mail/myconfig.mc . 448Use with caution as a make install will overwrite any existing 449.Pa /etc/mail/sendmail.cf . 450Note
