Refer to 107.Pa /usr/share/examples/etc/defaults/make.conf 108for a list of recognized 109.Va CPUTYPE 110options. 111.It Va CCVER 112.Pq Vt str 113Controls which GCC version to use by default. 114It should be set as 115.Li CCVER?= 116so as not to interfere with overrides from userland. 117We currently recommend that an override NOT be set in 118.Pa /etc/make.conf . 119Currently accepted values are 120.Dq gcc41 121(default). 122.It Va CFLAGS 123.Pq Vt str 124Controls the compiler setting when compiling C code. 125Optimization levels above 126.Fl O 127.Pq Fl O2 , No ... 128are not supported. 129.Va BDECFLAGS 130is provided as a set of 131.Xr gcc 1 132settings suggested by 133.An "Bruce Evans" Aq bde@FreeBSD.org 134for developing and testing changes. 135They can be used, if set, by: 136.Bd

151If you want to add to the 152.Va CXXFLAGS 153value, use 154.Dq Li += 155instead of 156.Dq Li = . 157.It Va INSTALL 158.Pq Vt str 159the default install command. 160To have components compared before doing the install, use 161.Bd -literal -offset indent 162INSTALL="install -C" 163.Ed 164.It Va LOCAL_DIRS 165.Pq Vt str 166List any directories that should be entered when running make 167.Pa

204when WARNS is in effect. 205.It Va WANT_HESIOD 206.Pq Vt bool 207Set this to build 208.Xr hesiod 3 209support into libc. 210.It Va NO_NS_CACHING 211.Pq Vt bool 212Set this to disable name caching in the nsswitch subsystem. 213The generic caching daemon, 214.Xr nscd 8 , 215will not be built either if this option is set. 216.El 217.Pp 218The following list provides a name and short description for variables 219that are only used doing a kernel build: 220.Bl -tag -width Ar 221.It Va BOOT_COMCONSOLE_PORT 222.Pq Vt str 223The port address to use for the console if the boot blocks have 224been

258.Pq Vt bool 259While not a buildkernel-affected option, there is no better place for this. 260By default the 261.Xr pxeboot 8 262loader retrieves the kernel via NFS. 263Defining this and recompiling 264.Pa /usr/src/sys/boot 265will cause it to retrieve the kernel via TFTP. 266This allows pxeboot to load a custom BOOTP diskless kernel yet 267still mount the server's 268.Pa / 269rather than load the server's kernel. 270.It Va NO_CPU_COPTFLAGS 271.Pq Vt str 272Setting this variable will prevent CPU specific compiler flags 273from being automatically added to 274.Va COPTFLAGS
