| ALWAYS_CHECK_MAKE |
| | (Vt bool) Instructs the top-level makefile in the source tree (normally /usr/src) to always check if make(1) is up-to-date. Normally this is only done for the world and buildworld targets to handle upgrades from older versions of
.Fx . |
| CFLAGS |
| | (Vt str) Controls the compiler setting when compiling C code. Optimization levels other than -O and -O2 are not supported. BDECFLAGS is provided as a set of gcc(1) settings suggested by
.An "Bruce Evans" Aq bde@FreeBSD.org for developing and testing changes. They can be used, if set, by:
CFLAGS+=${BDECFLAGS}
|
| CPUTYPE |
| | (Vt str) Controls which processor should be targeted for generated code. This controls processor-specific optimizations in certain code (currently only OpenSSL) as well as modifying the value of CFLAGS and COPTFLAGS to contain the appropriate optimization directive to gcc(1). The automatic setting of CFLAGS and COPTFLAGS may be overridden using the NO_CPU_CFLAGS and NO_CPU_COPTFLAGS variables, respectively. Refer to /usr/share/examples/etc/make.conf for a list of recognized CPUTYPE options. |
| NO_CPU_CFLAGS |
| | (Vt str) Setting this variable will prevent CPU specific compiler flags from being automatically added to CFLAGS during compile time. |
| NO_CPU_COPTFLAGS |
| | (Vt str) Setting this variable will prevent CPU specific compiler flags from being automatically added to COPTFLAGS during compile time. |
| CVS_UPDATE |
| | (Vt bool) Set this to use cvs(1) to update your ports with ""make update"". |
| CXXFLAGS |
| | (Vt str) Controls the compiler settings when compiling C++ code. CXXFLAGS is initially set to the value of CFLAGS. If you want to add to the CXXFLAGS value, use "+=" instead of "=". |
| INSTALL |
| | (Vt str) the default install command. To install only files for which the target differs or does not exist, use
INSTALL="install -C"
Note that some makefiles (including those in /usr/share/mk) may hardcode options for the supplied install command. |
| LOCAL_DIRS |
| | (Vt str) List any directories that should be entered when doing make’s in /usr/src in this variable. |
| MAKE_SHELL |
| | (Vt str) Controls the shell used internally by make(1) to process the command scripts in makefiles. sh(1), ksh(1), and csh(1) all currently supported. "MAKE_SHELL?=sh" |
| MTREE_FOLLOWS_SYMLINKS |
| | (Vt str) Set this to "-L" to cause mtree(8) to follow symlinks. |
| NO_DOCUPDATE |
| | (Vt bool) Set this to not update the doc tree during ""make update"". |
| NO_PORTSUPDATE |
| | (Vt bool) Set this to not update the ports tree during ""make update"". |
| SUP_UPDATE |
| | (Vt bool) Set this to use cvsup(1) to update your ports with ""make update"". |
| SUP | (Vt str) The location of the cvsup(1) command for ""make update"". |
| SUPFLAGS |
| | (Vt str) The flag for the sup(1) command when doing ""make update"". This defaults to [-g-L 2]. |
| SUPHOST |
| | (Vt str) The hostname of the sup server to use when doing ""make update"". |
| SUPFILE |
| | (Vt str) The first supfile to use when doing a ""make update"". This defaults to /usr/share/examples/cvsup/standard-supfile. |
| SUPFILE1 |
| | (Vt str) The second supfile to use when doing a ""make update"". This defaults to /usr/share/examples/cvsup/secure-supfile. |
| SUPFILE2 |
| | (Vt str) The third supfile to use when doing a ""make update"". This defaults to /usr/share/examples/cvsup/secure-supfile. |
| PORTSSUPFILE |
| | (Vt str) The ports supfile to use when doing a ""make update"". This defaults to /usr/share/examples/cvsup/ports-supfile. |
| DOCSUPFILE |
| | (Vt str) The documentation supfile to use when doing a ""make update"". This defaults to /usr/share/examples/cvsup/doc-supfile. |

The following list provides a name and short description for variables that are only used doing a kernel build:
| BOOT_COMCONSOLE_PORT |
| | (Vt str) The port address to use for the console if the boot blocks have been configured to use a serial console instead of the keyboard/video card. |
| BOOT_COMCONSOLE_SPEED |
| | (Vt int) The baud rate to use for the console if the boot blocks have been configured to use a serial console instead of the keyboard/video card. |
| BOOTWAIT |
| | (Vt int) Controls the amount of time the kernel waits for a console keypress before booting the default kernel. The value is approximately milliseconds. Keypresses are accepted by the BIOS before booting from disk, making it possible to give custom boot parameters even when this is set to 0. |
| COPTFLAGS |
| | (Vt str) Controls the compiler settings when building the kernel. Optimization levels above [-O-( -O2 -, ...)] are not guaranteed to work. |
| KERNCONF |
| | (Vt str) Controls which kernel configurations will be built by ""${MAKE} buildkernel"" and installed by ""${MAKE} installkernel"". For example,
KERNCONF=MINE DEBUG GENERIC OTHERMACHINE
will build the kernels specified by the config files MINE, DEBUG, GENERIC, and OTHERMACHINE, and install the kernel specified by the config file MINE. It defaults to GENERIC. |
| LOADER_TFTP_SUPPORT |
| | (Vt bool) While not a buildkernel-affected option, there is no better place for this. By default the pxeboot(8) loader retrieves the kernel via NFS. Defining this and recompiling /usr/src/sys/boot will cause it to retrieve the kernel via TFTP. This allows pxeboot(8) to load a custom BOOTP diskless kernel yet still mount the server’s / rather than load the server’s kernel. |

| PORTS_MODULES |
| | Set this to the list of ports you wish to rebuild every time the kernel is built. |
| NO_KERNELCONFIG |
