NetBSD System variables

NETBSDSRCDIR

The path to the top level of the NetBSD sources. If make(1) is run from within the NetBSD source tree, the default is the top level of that tree (as determined by the presence of build.sh and tools/), otherwise BSDSRCDIR will be used.

BSDOBJDIR

The real path to the ‘obj' tree for the NetBSD source tree.

Default: /usr/obj

BSDSRCDIR

The real path to the NetBSD source tree.

Default: /usr/src

BUILD

If defined, ‘make install' checks that the targets in the source directories are up-to-date and re-makes them if they are out of date, instead of blindly trying to install out of date or non-existent targets.

Default: Unset.

BUILDID

Identifier for the build. The identifier will be appended to object directory names, and can be consulted in the make(1) configuration file in order to set additional build parameters, such as compiler flags.

Default: Unset.

COPTS

Extra options for the C compiler. Should be appended to (e.g., COPTS+=-g), rather than explicitly set. Note that CPUFLAGS, not COPTS, should be used for compiler flags that select CPU-related options. Also note that CFLAGS should never be set in mk.conf.

CPUFLAGS

Additional flags passed to the compiler/assembler to select CPU instruction set options, CPU tuning options, etc. Such options should not be specified in COPTS, because some parts of the build process need to override CPU-related compiler options.

DESTDIR

Directory to contain the built NetBSD system. If set, special options are passed to the compilation tools to prevent their default use of the host system's /usr/include, /usr/lib, and so forth. This pathname should not end with a slash (/) character (for installation into the system's root directory, set DESTDIR to an empty string). The directory must reside on a file system which supports long file names and hard links.

Default: Empty string if USETOOLS is “yes”; unset otherwise.

Note: build.sh will provide a default of destdir.MACHINE (in the top-level .OBJDIR) unless run in ‘expert' mode

MAKEVERBOSE

Level of verbosity of status messages. Supported values:

0

No descriptive messages or commands executed by make(1) are shown.

1

Brief messages are shown describing what is being done, but the actual commands executed by make(1) are not displayed.

2

Descriptive messages are shown as above (prefixed with a ‘#'), and ordinary commands performed by make(1) are displayed.

3

In addition to the above, all commands performed by make(1) are displayed, even if they would ordinarily have been hidden through use of the “@” prefix in the relevant makefile.

4

In addition to the above, commands executed by make(1) are traced through use of the sh(1) “-x” flag.

Default: 2

MKATF

Can be set to “yes” or “no”. Indicates whether the Automated Testing Framework is built and installed.

Default: “yes”

The contents of METALOG is used during the generation of the distribution tar files to ensure that the appropriate file ownership is stored.

Default: “no”

MKUPDATE

Can be set to “yes” or “no”. Indicates whether all install operations intended to write to DESTDIR will compare file timestamps before installing, and skip the install phase if the destination files are up-to-date. This also has implications on full builds (see next subsection).

RELEASEDIR

If set, specifies the directory to which a release(7) layout will be written at the end of a “make release”.

Default: Unset.

Note: build.sh will provide a default of releasedir (in the top-level .OBJDIR) unless run in ‘expert' mode

TOOLDIR

Directory to hold the host tools, once built. This directory should be unique to a given host system and NetBSD source tree. (However, multiple targets may share the same TOOLDIR; the target-dependent files have unique names.) If unset, a default based on the uname(1) information of the host platform will be created in the .OBJDIR of src.

Default: Unset.

USE_FORT

Default: “yes”

USE_JEMALLOC

Can be set to “yes” or “no”. Indicates whether the jemalloc allocator (which is designed for improved performance with threaded applications) is used instead of the phkmalloc allocator (that was the default until NetBSD 5.0).

Default: “yes”

USE_KERBEROS

Can be set to “yes” or “no”. Indicates whether Kerberos v5 support is enabled in the various applications that support it. If MKKERBEROS=no, USE_KERBEROS will also be forced to “no”.

USE_SKEY

Can be set to “yes” or “no”. Indicates whether S/key support is enabled in the various applications that support it. If MKSKEY=no, USE_SKEY will also be forced to “no”.

Default: “yes”

This is mutually exclusive to USE_PAM!=no.

USE_SSP

Can be set to “yes” or “no”. Indicates whether GCC stack-smashing protection (SSP) support, which detects stack overflows and aborts the program, is enabled. This imposes some performance penalty.

Default: “no”

USE_YP

Can be set to “yes” or “no”. Indicates whether YP (NIS) support is enabled in the various applications that support it. If MKYP=no, USE_YP will also be forced to “no”.

Default: “yes”

USETOOLS

Indicates whether the tools specified by TOOLDIR should be used as part of a build in progress. Must be set to “yes” if cross-compiling.

yes

Use the tools from TOOLDIR.

no

Do not use the tools from TOOLDIR, but refuse to build native compilation tool components that are version-specific for that tool.

never

Do not use the tools from TOOLDIR, even when building native tool components. This is similar to the traditional NetBSD build method, but does not verify that the compilation tools in use are up-to-date enough in order to build the tree successfully. This may cause build or runtime problems when building the whole NetBSD source tree.

Default: “yes” if building all or part of a whole NetBSD source tree (detected automatically); “no” otherwise (to preserve traditional semantics of the <bsd.*.mk> make(1) include files).

X11FLAVOUR

Picks which X11 distribution to cross-build with NetBSD. Set to either “Xorg” or “XFree86”. Only relevant if MKX11!=no.

Default: “Xorg” on alpha, i386, macppc, shark and sparc64 platforms. “XFree86” on everything else.
