MAKE.CONF 5 29.Os 30.Sh NAME 31.Nm make.conf 32.Nd system build information 33.Sh DESCRIPTION 34The file 35.Nm 36contains settings that control the compilation of the 37.Fx 38sources 39and ported applications. 40The file 41.Nm 42is generally created by the system administrator when the values need 43to be changed from their defaults. 44.Pp 45The purpose of 46.Nm 47is not to run commands or perform compilation actions 48directly. 49Instead, it is included by the 50various makefiles in 51.Pa /usr/src , 52.Pa /usr/ports 53and 54.Pa /usr/doc 55which conditionalize their 56internal actions according to the settings found there. 57.Pp 58The 59.Pa /etc/make.conf 60file is included from the appropriate 61.Pa Makefile 62which specifies the default settings for all the available options. 63Options need only be specified in 64.Pa /etc/make.conf 65when the system administrator wishes to override these defaults. 66.Pp 67The build procedures occur in four broad areas: the world, the kernel, 68documentations and ports. 69Variables set in 70.Nm 71may be applicable during builds in one, two, or all four of these 72areas. 73They may be specified for a particular build via the 74.Fl D 75option of 76.Xr make 1 . 77.Pp 78The following lists provide a name and short description for each 79variable you can use during the indicated builds. 80The values of 81variables flagged as 82.Vt bool 83are ignored; the variable being 84set at all (even to 85.Dq Li FALSE 86or 87.Dq Li NO ) 88causes it to 89be treated as if it were set. 90.Pp 91The following list provides a name and short description for variables 92that are used for all builds, or are used by the 93.Pa makefiles 94for things other than builds. 95.Bl -tag -width Ar 96.It Va ALWAYS_CHECK_MAKE 97.Pq Vt bool 98Instructs the top-level makefile in the source tree (normally 99.Pa /usr/src ) 100to always check if 101.Xr make 1 102is up-to-date. 103Normally this is only done for the world and buildworld targets to handle 104upgrades from older versions of 105.Fx . 106.It Va CFLAGS 107.Pq Vt str 108Controls the compiler setting when compiling C code. 109Optimization levels other than 110.Fl O 111and 112.Fl O2 113are not supported. 114.Va BDECFLAGS 115is provided as a set of 116.Xr gcc 1 117settings suggested by 118.An "Bruce Evans" Aq bde@FreeBSD.org 119for developing and testing changes. 120They can be used, if set, by: 121.Pp 122.Bd -literal -offset indent 123CFLAGS+=${BDECFLAGS} 124.Ed 125.It Va CPUTYPE 126.Pq Vt str 127Controls which processor should be targeted for generated 128code. 129This controls processor-specific optimizations in 130certain code (currently only OpenSSL) as well as modifying 131the value of 132.Va CFLAGS 133and 134.Va COPTFLAGS 135to contain the appropriate optimization directive to 136.Xr gcc 1 . 137The automatic setting of 138.Va CFLAGS 139and 140.Va COPTFLAGS 141may be overridden using the 142.Va NO_CPU_CFLAGS 143and 144.Va NO_CPU_COPTFLAGS 145variables, respectively. 146Refer to 147.Pa /usr/share/examples/etc/make.conf 148for a list of recognized 149.Va CPUTYPE 150options. 151.It Va NO_CPU_CFLAGS 152.Pq Vt str 153Setting this variable will prevent CPU specific compiler flags 154from being automatically added to 155.Va CFLAGS 156during compile time. 157.It Va NO_CPU_COPTFLAGS 158.Pq Vt str 159Setting this variable will prevent CPU specific compiler flags 160from being automatically added to 161.Va COPTFLAGS 162during compile time. 163.It Va CVS_UPDATE 164.Pq Vt bool 165Set this to use 166.Xr cvs 1 167to update your ports with 168.Dq Li "make update" . 169.It Va CXXFLAGS 170.Pq Vt str 171Controls the compiler settings when compiling C++ code. 172.Va CXXFLAGS 173is initially set to the value of 174.Va CFLAGS . 175If you want to 176add to the 177.Va CXXFLAGS 178value, use 179.Dq Li += 180instead of 181.Dq Li = . 182.It Va INSTALL 183.Pq Vt str 184the default install command. 185To install only files for which the target differs or does not exist, use 186.Bd -literal -offset indent 187INSTALL="install -C" 188.Ed 189Note that some makefiles (including those in 190.Pa /usr/share/mk ) 191may hardcode options for the supplied install command. 192.It Va LOCAL_DIRS 193.Pq Vt str 194List any directories that should be entered when doing 195make's in 196.Pa /usr/src 197in this variable. 198.It Va MAKE_SHELL 199.Pq Vt str 200Controls the shell used internally by 201.Xr make 1 202to process the command scripts in makefiles. 203.Xr sh 1 , 204.Xr ksh 1 , 205and 206.Xr csh 1 207all currently supported. 208.Pp 209.Dl "MAKE_SHELL?=sh" 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 NO_DOCUPDATE 218.Pq Vt bool 219Set this to not update the doc tree during 220.Dq Li "make update" . 221.It Va NO_PORTSUPDATE 222.Pq Vt bool 223Set this to not update the ports tree during 224.Dq Li "make update" . 225.It Va SUP_UPDATE 226.Pq Vt bool 227Set this to use 228.Xr cvsup 1 229to update your ports with 230.Dq Li "make update" . 231.It Va SUP 232.Pq Vt str 233The location of the 234.Xr cvsup 1 235command for 236.Dq Li "make update" . 237.It Va SUPFLAGS 238.Pq Vt str 239The flag for the 240.Xr sup 1 241command when doing 242.Dq Li "make update" . 243This defaults to 244.Op Fl g L Ar 2 . 245.It Va SUPHOST 246.Pq Vt str 247The hostname of the sup server to use when doing 248.Dq Li "make update" . 249.It Va SUPFILE 250.Pq Vt str 251The first 252.Ar supfile 253to use when doing a 254.Dq Li "make update" . 255This defaults to 256.Pa /usr/share/examples/cvsup/standard\-supfile . 257.It Va SUPFILE1 258.Pq Vt str 259The second 260.Ar supfile 261to use when doing a 262.Dq Li "make update" . 263This defaults to 264.Pa /usr/share/examples/cvsup/secure\-supfile . 265.It Va SUPFILE2 266.Pq Vt str 267The third 268.Ar supfile 269to use when doing a 270.Dq Li "make update" . 271This defaults to 272.Pa /usr/share/examples/cvsup/secure\-supfile . 273.It Va PORTSSUPFILE 274.Pq Vt str 275The ports 276.Ar supfile 277to use when doing a 278.Dq Li "make update" . 279This defaults to 280.Pa /usr/share/examples/cvsup/ports\-supfile . 281.It Va DOCSUPFILE 282.Pq Vt str 283The documentation 284.Ar supfile 285to use when doing a 286.Dq Li "make update" . 287This defaults to 288.Pa /usr/share/examples/cvsup/doc\-supfile . 289.El 290.Pp 291The following list provides a name and short description for variables 292that are only used doing a kernel build: 293.Bl -tag -width Ar 294.It Va BOOT_COMCONSOLE_PORT 295.Pq Vt str 296The port address to use for the console if the boot blocks have 297been configured to use a serial console instead of the keyboard/video card. 298.It Va BOOT_COMCONSOLE_SPEED 299.Pq Vt int 300The baud rate to use for the console if the boot blocks have 301been configured to use a serial console instead of the keyboard/video card. 302.It Va BOOTWAIT 303.Pq Vt int 304Controls the amount of time the kernel waits for a console keypress 305before booting the default kernel. 306The value is approximately milliseconds. 307Keypresses are accepted by the BIOS before booting from disk, 308making it possible to give custom boot parameters even when this is 309set to 0. 310.It Va COPTFLAGS 311.Pq Vt str 312Controls the compiler settings when building the 313kernel. 314Optimization levels above 315.Oo Fl O ( O2 , No ...\& ) Oc 316are not guaranteed to work. 317.It Va KERNCONF 318.Pq Vt str 319Controls which kernel configurations will be 320built by 321.Dq Li "${MAKE} buildkernel" 322and installed by 323.Dq Li "${MAKE} installkernel" . 324For example, 325.Bd -literal -offset indent 326KERNCONF=MINE DEBUG GENERIC OTHERMACHINE 327.Ed 328.Pp 329will build the kernels specified by the config files 330.Pa MINE , DEBUG , GENERIC , 331and 332.Pa OTHERMACHINE , 333and install the kernel specified by the config file 334.Pa MINE . 335It defaults to 336.Pa GENERIC . 337.It Va LOADER_TFTP_SUPPORT 338.Pq Vt bool 339While not a buildkernel-affected option, there is no better place for this. 340By default the 341.Xr pxeboot 8 342loader retrieves the kernel via NFS. 343Defining this and recompiling 344.Pa /usr/src/sys/boot 345will cause it to retrieve the kernel via TFTP. 346This allows 347.Xr pxeboot 8 348to load a custom BOOTP diskless kernel yet 349still mount the server's 350.Pa / 351rather than load the server's kernel. 352.It Va MODULES_OVERRIDE 353.Pq Vt str 354Set to a list of modules to build instead of all of them. 355.It Va WITHOUT_MODULES 356.Pq Vt str 357Set to a list of modules to exclude from the build. 358This provides a 359somewhat easier way to exclude modules you are certain you will never 360need than specifying 361.Va MODULES_OVERRIDE . 362This is applied 363.Em after 364.Va MODULES_OVERRIDE . 365.It Va PORTS_MODULES 366Set this to the list of ports you wish to rebuild every time the kernel 367is built. 368.It Va NO_KERNELCONFIG 369.Pq Vt bool 370Set this to skip running 371.Xr config 8 372during 373.Dq Li "${MAKE} buildkernel" . 374.It Va NO_KERNELDEPEND 375.Pq Vt bool 376Set this to skip running 377.Dq Li "${MAKE} depend" 378during 379.Dq Li "${MAKE} buildkernel" . 380.It Va NO_MODULES 381.Pq Vt bool 382Set to not build modules with the kernel. 383.El 384.Pp 385The following list provides a
