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 CFLAGS 97.Pq Vt str 98Controls the compiler setting when compiling C code. 99Optimization levels above 100.Fl O 101.Pq Fl O2 , No ... 102are not supported. 103.Va BDECFLAGS 104is provided as a set of 105.Xr gcc 1 106settings suggested by 107.An

Vt str 116Controls which processor should be targeted for generated 117code. 118This controls processor-specific optimizations in 119certain code (currently only OpenSSL) as well as modifying 120the value of 121.Va CFLAGS 122and 123.Va COPTFLAGS 124to contain the appropriate optimization directive to 125.Xr gcc 1 . 126The automatic setting of 127.Va CFLAGS 128and 129.Va COPTFLAGS 130may be overridden using the 131.Va NO_CPU_CFLAGS 132and 133.Va NO_CPU_COPTFLAGS 134variables, respectively. 135Refer to 136.Pa /usr/share/examples/etc/make.conf 137for a list of recognized 138.Va CPUTYPE 139options. 140.It Va NO_CPU_CFLAGS 141.Pq Vt str 142Setting this variable will prevent CPU specific compiler flags 143from being automatically added to 144.Va CFLAGS 145during compile time. 146.It Va NO_CPU_COPTFLAGS 147.Pq Vt str 148Setting this variable will prevent CPU specific compiler flags 149from being automatically added to 150.Va COPTFLAGS 151during compile time. 152.It Va CVS_UPDATE 153.Pq Vt bool 154Set this to use 155.Xr cvs 1 156to update your ports with 157.Dq Li "make update" . 158.It Va CXXFLAGS 159.Pq Vt str 160Controls the compiler settings when compiling C++ code. 161.Va CXXFLAGS 162is initially set to the value of 163.Va CFLAGS . 164If you want to 165add to the 166.Va CXXFLAGS 167value, use 168.Dq Li += 169instead of 170.Dq Li = . 171.It Va INSTALL 172.Pq Vt str 173the default install command. 174To have commands compared before doing 175the install, use 176.Bd -literal -offset indent 177INSTALL="install -C" 178.Ed 179.It Va LOCAL_DIRS 180.Pq Vt str 181List any directories that should be entered when doing 182make's in 183.Pa /usr/src 184in this variable. 185.It Va MAKE_SHELL 186.Pq Vt str 187Controls the shell used internally by 188.Xr make 1 189to process the command scripts in makefiles. 190.Xr sh 1 , 191.Xr ksh 1 , 192and 193.Xr csh 1 194all currently supported. 195.Pp 196.Dl "MAKE_SHELL?=sh" 197.It Va MTREE_FOLLOWS_SYMLINKS 198.Pq Vt str 199Set this to 200.Dq Fl L 201to cause 202.Xr mtree 8 203to follow symlinks. 204.It Va NO_DOCUPDATE 205.Pq Vt bool 206Set this to not update the doc tree during 207.Dq Li "make update" . 208.It Va NO_PORTSUPDATE 209.Pq Vt bool 210Set this to not update the ports tree during 211.Dq Li "make update" . 212.It Va SUP_UPDATE 213.Pq Vt bool 214Set this to use 215.Xr cvsup 1 216to update your ports with 217.Dq Li "make update" . 218.It Va SUP 219.Pq Vt str 220The location of the 221.Xr cvsup 1 222command for 223.Dq Li "make update" . 224.It Va SUPFLAGS 225.Pq Vt str 226The flag for the 227.Xr sup 1 228command when doing 229.Dq Li "make update" . 230This defaults to 231.Op Fl g L Ar 2 . 232.It Va SUPHOST 233.Pq Vt str 234The hostname of the sup server to use when doing 235.Dq Li "make

Va SUPFILE1 245.Pq Vt str 246The second 247.Ar supfile 248to use when doing a 249.Dq Li "make update" . 250This defaults to 251.Pa /usr/share/examples/cvsup/secure\-supfile . 252.It Va SUPFILE2 253.Pq Vt str 254The third 255.Ar supfile 256to use when doing a 257.Dq Li "make update" . 258This defaults to 259.Pa /usr/share/examples/cvsup/secure\-supfile . 260.It Va PORTSSUPFILE 261.Pq Vt str 262The ports 263.Ar supfile 264to use when doing a 265.Dq Li "make update" . 266This defaults to 267.Pa /usr/share/examples/cvsup/ports\-supfile . 268.It Va DOCSUPFILE 269.Pq Vt str 270The documentation 271.Ar supfile 272to use when doing a 273.Dq Li "make update" . 274This defaults to 275.Pa /usr/share/examples/cvsup/doc\-supfile . 276.El 277.Pp 278The following list provides a name and short description for variables 279that are only used doing a kernel build: 280.Bl -tag -width Ar 281.It Va BOOT_COMCONSOLE_PORT 282.Pq Vt str 283The port address to use for the console if the boot blocks have 284been configured to use a serial console instead of the keyboard/video card. 285.It Va BOOT_COMCONSOLE_SPEED 286.Pq Vt int 287The baud rate to use for the console if the boot blocks have 288been configured to use a serial console instead of the keyboard/video card. 289.It Va BOOTWAIT 290.Pq Vt int 291Controls the amount of time the kernel waits for a console keypress 292before booting the default kernel. 293The value is approximately milliseconds. 294Keypresses are accepted by the BIOS before booting from disk, 295making it possible to give custom boot parameters even when this is 296set to 0. 297.It Va COPTFLAGS 298.Pq Vt str 299Controls the compiler settings when building the 300kernel. 301Optimization levels above 302.Oo Fl O ( O2 , No ...\& ) Oc 303are not guaranteed to

option, there is no better place for this. 327By default the 328.Xr pxeboot 8 329loader retrieves the kernel via NFS. 330Defining this and recompiling 331.Pa /usr/src/sys/boot 332will cause it to retrieve the kernel via TFTP. 333This allows 334.Xr pxeboot 8 335to load a custom BOOTP diskless kernel yet 336still mount the server's 337.Pa / 338rather than load the server's kernel. 339.It Va

European countries. 409It is 410.Em "YOUR RESPONSIBILITY" 411to determine if you can legally use IDEA. 412.It Va MAKE_KERBEROS5 413.Pq Vt bool 414Set this to build Kerberos5 (KTH Heimdal). 415.Em

422Otherwise, it will be 423installed without the set-user-ID bit set. 424.It Va ENABLE_SUID_NEWGRP 425.Pq Vt bool 426Set this to install 427.Xr newgrp 1 428with the set-user-ID bit set. 429Otherwise, 430.Xr newgrp 1 431will not be able to change users' groups. 432.It Va ENABLE_SUID_SSH 433.Pq Vt bool 434Set this to install 435.Xr ssh 1 436with the set-user-ID bit turned on. 437.It Va MODULES_WITH_WORLD 438.Pq Vt bool 439Set to build modules with the system instead of the kernel. 440.It Va NO_CVS 441.Pq Vt bool 442Set to not build CVS. 443.It Va NO_CXX 444.Pq Vt bool 445Set to not
