Lionel Sambuc 84d9c625bf Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)
- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

# @(#)bsd.README 8.2 (Berkeley) 4/2/94
This is the README file for the make "include" files for the NetBSD
source tree. The files are installed in /usr/share/mk, and are,
by convention, named with the suffix ".mk".
Note, this file is not intended to replace reading through the .mk
files for anything tricky.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
RANDOM THINGS WORTH KNOWING:
The files are simply C-style #include files, and pretty much behave like
you'd expect. The syntax is slightly different in that a single '.' is
used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
One difference that will save you lots of debugging time is that inclusion
of the file is normally done at the *end* of the Makefile. The reason for
this is because .mk files often modify variables and behavior based on the
values of variables set in the Makefile. To make this work, remember that
the FIRST target found is the target that is used, i.e. if the Makefile has:
a:
echo a
a:
echo a number two
the command "make a" will echo "a". To make things confusing, the SECOND
variable assignment is the overriding one, i.e. if the Makefile has:
a= foo
a= bar
b:
echo ${a}
the command "make b" will echo "bar". This is for compatibility with the
way the V7 make behaved.
It's fairly difficult to make the BSD .mk files work when you're building
multiple programs in a single directory. It's a lot easier to split up the
programs than to deal with the problem. Most of the agony comes from making
the "obj" directory stuff work right, not because we switched to a new version
of make. So, don't get mad at us, figure out a better way to handle multiple
architectures so we can quit using the symbolic link stuff. (Imake doesn't
count.)
The file .depend in the source directory is expected to contain dependencies
for the source files. This file is read automatically by make after reading
the Makefile.
The variable DESTDIR works as before. It's not set anywhere but will change
the tree where the file gets installed.
The profiled libraries are no longer built in a different directory than
the regular libraries. A new suffix, ".po", is used to denote a profiled
object, and ".pico" denotes a shared (position-independent) object.
There are various make variables used during the build.
Many variables support a (case sensitive) value of "no" or "yes",
and are tested with ${VAR} == "no" and ${VAR} != "no" .
The basic rule for the variable naming scheme is as follows:
HOST_xxx A command that runs on the host machine regardless of
whether or not the system is being cross compiled, or
flags for such a command.
MKxxx Can be set to "no" to disable functionality, or
"yes" to enable it.
Usually defaults to "yes", although some variables
default to "no".
Due to make(1) implementation issues, if a temporary
command-line override of a mk.conf(5) or <bsd.own.mk>
setting is required whilst still honoring a particular
Makefile's setting of MKxxx, use
env MKxxx=value make
instead of
make MKxxx=value
NOxxx If defined, disables a feature.
Not intended for users.
This is to allow Makefiles to disable functionality
that they don't support (such as missing man pages).
NOxxx variables must be defined before <bsd.own.mk>
is included.
TOOL_xxx A tool that is provided as part of the USETOOLS
framework. When not using the USETOOLS framework,
TOOL_xxx variables should refer to tools that are
already installed on the host system.
The following variables that control how things are made/installed that
are not set by default. These should not be set by Makefiles; they're for
the user to define in MAKECONF (see <bsd.own.mk>, below, or mk.conf(5))
or on the make(1) command line:
BUILD If defined, 'make install' checks that the targets in the
source directories are up-to-date and remakes them if they
are out of date, instead of blindly trying to install
out of date or non-existent targets.
MAKEVERBOSE Control how "verbose" the standard make(1) rules are.
Default: 2
Supported values:
0 Minimal output ("quiet")
1 Describe what is occurring
2 Describe what is occurring and echo the actual command
3 Ignore the effect of the "@" prefix in make commands

the libraries is disabled, don't build the NetBSD test suite
either.

more recently modified in the source directories that their
installed counterparts.
Default: no
MKX11 If not "no", depending on the value of ${X11FLAVOUR},

detects stack overflows and aborts the program. The
stack protection code imposes a performance penalty
of about 5%.
Default: "no", unless "USE_FORT" is set to "yes"
USE_FORT If "yes" turns on substitute wrappers for commonly used
functions that do not do bounds checking regularly, but
they could in some cases by using the gcc

"XFree86" on everything else.
COPTS.lib<lib>
OBJCOPTS.lib<lib>
LDADD.lib<lib>
CPPFLAGS.lib<lib>
CXXFLAGS.lib<lib>
COPTS.<prog>
OBJCCOPTS.<prog>
LDADD.<prog>
CPPFLAGS.<prog>
CXXFLAGS.<prog> These provide a way to specify additions to the associated
variables in a way that applies only to a particular library
or program. <lib> corresponds to the LIB variable set in
the library's makefile. <prog> corresponds to either PROG
or PROG_CXX (if set). For example, if COPTS.libcrypto is
set to "-g", "-g" will be added to COPTS only when compiling
the crypto library.
The active compiler is selected using the following variables:
AVAILABLE_COMPILER
List of available compiler suites. Processed in order
for selecting the active compiler for each frontend.
HAVE_PCC If defined, PCC is present and enabled.
HAVE_LLVM If defined, LLVM/Clang is present and enabled.
UNSUPPORTED_COMPILER.xxx
If defined, the support for compiler "xxx" is disabled.
For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist:
ACTIVE_CC Active compile suite for the CC frontend.
SUPPORTED_CC Compile suite with support for the CC frontend.
TOOL_CC.xxx Path to the CC frontend for compiler "xxx"
=-=-=-=-= sys.mk =-=-=-=-=
The include file <sys.mk> has the default rules for all makes, in the BSD
environment or otherwise. You probably don't want to touch this file.
=-=-=-=-= bsd.own.mk =-=-=-=-=
The include file <bsd.own.mk> contains source tree configuration parameters,
such as the owners, groups, etc. for both manual pages and binaries, and
a few global "feature configuration" parameters.
It has no targets.
To get system-specific configuration parameters, <bsd.own.mk> will try to
include the file specified by the "MAKECONF" variable. If MAKECONF is not
set, or no such file exists, the system make configuration file, /etc/mk.conf
is included. These files may define any of the variables described below.
<bsd.own.mk> sets the following variables, if they are not already defined
(defaults are in brackets):
NETBSDSRCDIR Top of the NetBSD source tree.
If _SRC_TOP_ != "", that will be used as the default,
otherwise BSDSRCDIR will be used as the default.
Various makefiles within the NetBSD source tree will
use this to reference the top level of the source tree.
_SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk>
based on the presence of tools/ and build.sh. This variable
is "internal" to <bsd.own.mk>, although its value is only
determined once and then propagated to all sub-makes.
_NETBSD_VERSION_DEPENDS
A list of files which contain information about
the version of the NetBSD being built. This is
defined only if the current directory appears
to be inside a NetBSD source tree. The list of
files includes ${NETBSDSRCDIR}/sys/sys/param.h
(which contains the kernel version number),
${NETBSDSRCDIR}/sys/conf/newvers.sh and
${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
interpret the information in sys/sys/param.h), and
${_SRC_TOP_OBJ_}/params (which is an optional file,
created by "make build" in ${_SRC_TOP_}/Makefile,
containing all the variables that may influence the
build).
Targets that depend on the NetBSD version, or on
variables defined at build time, can declare a
dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
version.c: ${_NETBSD_VERSION_DEPENDS}
commands to create version.c
BSDSRCDIR The real path to the system sources, so that 'make obj'

own install script so that the entire system can be made
stripped/not-stripped using a single knob. []
COPY The flag passed to the install program to cause the binary
to be copied rather than moved. This is to be used when
building our own install script so that the entire system
can either be installed with copies, or with moves using
a single knob. [-c]
MAKEDIRTARGETENV
Environment variables passed to the child make process
invoked by MAKEDIRTARGET.
MAKEDIRTARGET dir target [params]
Runs "cd $${dir} && ${MAKE} [params] $${target}",
displaying a "pretty" message whilst doing so.

RELEASEMACHINE Subdirectory or path component used for the following
paths:
distrib/${RELEASEMACHINE}

etc/etc.${RELEASEMACHINE}
Used when building a release. [${MACHINE}]
Additionally, the following variables may be set by <bsd.own.mk> or in a
make configuration file to modify the behavior of the system build
process (default values are in brackets along with comments, if set by
<bsd.own.mk>):
USETOOLS Indicates whether the tools specified by ${TOOLDIR} should
be used as part of a build in progress.
Supported values:
yes Use the tools from TOOLDIR.
Must be set to this if cross-compiling.
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).
OBJECT_FMT Object file format. [set to "ELF" on architectures that
use ELF -- currently all architectures].
TOOLCHAIN_MISSING
If not "no", this indicates that the platform being built
does not have a working in-tree toolchain. If the
${MACHINE_ARCH} in question falls into this category,
TOOLCHAIN_MISSING is conditionally assigned the value "yes".
Otherwise, the variable is unconditionally assigned the
value "no".
If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are
unconditionally assigned the value "no".
EXTERNAL_TOOLCHAIN
This variable is not directly set by <bsd.own.mk>, but
including <bsd.own.mk> is the canonical way to gain
access to this variable. The variable should be defined
either in the user's environment or in the user's mk.conf
file. If defined, this variable indicates the root of
an external toolchain which will be used to build the
tree. For example, if a platform is a ${TOOLCHAIN_MISSING}
platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
cross-compile framework.
If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
assigned the value "no", since the external version of the
compiler may not be able to build the library components of
the in-tree compiler.
NOTE: This variable is not yet used in as many places as
it should be. Expect the exact semantics of this variable
to change in the short term as parts of the cross-compile
framework continue to be cleaned up.
The following variables are defined to commands to perform the
appropriate operation, with the default in [brackets]. Note that
the defaults change if USETOOLS == "yes":
TOOL_AMIGAAOUT2BB aout to Amiga bootblock converter. [amiga-aout2bb]
TOOL_AMIGAELF2BB ELF to Amiga bootblock converter. [amiga-elf2bb]
TOOL_AMIGATXLT Amige assembly language format translator. [amiga-txlt]
TOOL_ASN1_COMPILE ASN1 compiler. [asn1_compile]
TOOL_AWK Pattern-directed scanning/processing language. [awk]
TOOL_CAP_MKDB Create capability database. [cap_mkdb]
TOOL_CAT Concatenate and print files. [cat]
TOOL_CKSUM Display file checksums. [cksum]
TOOL_COMPILE_ET Error table compiler. [compile_et]
TOOL_CONFIG Build kernel compilation directories. [config]
TOOL_CRUNCHGEN Generate crunched binary build environment. [crunchgen]
TOOL_CTAGS Create a tags file. [ctags]
TOOL_DB Manipulate db(3) databases. [db]
TOOL_DISKLABEL Read and write disk pack label. [disklabel]

<bsd.own.mk> is generally useful when building your own Makefiles so that
they use the same default owners etc. as the rest of the tree.
=-=-=-=-= bsd.clean.mk =-=-=-=-=
The include file <bsd.clean.mk> defines the clean and cleandir
targets. It uses the following variables:
CLEANFILES Files to remove for both the clean and cleandir targets.
CLEANDIRFILES Files to remove for the cleandir target, but not for
the clean target.
MKCLEANSRC Controls whether or not the clean and cleandir targets
will delete files from both the object directory,
${.OBJDIR}, and the source directory, ${.CURDIR}.
If MKCLEANSRC is set to "no", then the file names in
CLEANFILES or CLEANDIRFILES are interpreted relative
to the object directory, ${.OBJDIR}. This is the
traditional behaviour.
If MKCLEANSRC is set to "yes", then the file deletion
is performed relative to both the object directory,
${.OBJDIR}, and the source directory, ${.CURDIR}. (This
has no effect if ${.OBJDIR} is the same as ${.CURDIR}.)
Deleting files from ${.CURDIR} is intended to remove
stray output files that had been left in the source
directory by an earlier build that did not use object
directories.
The default is MKCLEANSRC=yes. If you always build with
separate object directories, and you are sure that there
are no stray files in the source directories, then you
may set MKCLEANSRC=no to save some time.
MKCLEANVERIFY Controls whether or not the clean and cleandir targets
will verify that files have been deleted.
If MKCLEANVERIFY is set to "no", then the files will
be deleted using a "rm -f" command, and its success or
failure will be ignored.
If MKCLEANVERIFY is set to "yes", then the success of
the "rm -f" command will be verified using an "ls"
command.
The default is MKCLEANVERIFY=yes. If you are sure that
there will be no problems caused by file permissions,
read-only file systems, or the like, then you may set
MKCLEANVERIFY=no to save some time.
To use the clean and cleandir targets defined in <bsd.clean.mk>, other
Makefiles or bsd.*.mk files should append file names to the CLEANFILES
or CLEANDIRFILES variables. For example:
CLEANFILES+= a.out
CLEANDIRFILES+= .depend
.include <bsd.clean.mk>
The files listed in CLEANFILES and CLEANDIRFILES must not be
directories, because the potential risk from running "rm -rf" commands
in bsd.clean.mk is considered too great. If you want to recursively
delete a directory as part of "make clean" or "make cleandir" then you
need to provide your own target.
=-=-=-=-= bsd.dep.mk =-=-=-=-=
The include file <bsd.dep.mk> contains the default targets for building
.depend files. It creates .d files from entries in SRCS and DPSRCS
that are C, C++, or Objective C source files, and builds .depend from the
.d files. All other files in SRCS and all of DPSRCS will be used as
dependencies for the .d files. In order for this to function correctly,
it should be .included after all other .mk files and directives that may
modify SRCS or DPSRCS. It uses the following variables:
SRCS List of source files to build the program.
DPSRCS List of source files which are needed for generating
dependencies, but are not needed in ${SRCS}.
=-=-=-=-= bsd.files.mk =-=-=-=-=
The include file <bsd.files.mk> handles the FILES variables and is included
from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
FILES The list of files to install.
CONFIGFILES Similar semantics to FILES, except that the files
are installed by the `configinstall' target,
not the `install' target.
The FILES* variables documented below also apply.
FILESOWN File owner. [${BINOWN}]
FILESGRP File group. [${BINGRP}]
FILESMODE File mode. [${NONBINMODE}]
FILESDIR The location to install the files.
FILESNAME Optional name to install each file as.
FILESOWN_<fn> File owner of the specific file <fn>.
FILESGRP_<fn> File group of the specific file <fn>.
FILESMODE_<fn> File mode of the specific file <fn>.
FILESDIR_<fn> The location to install the specific file <fn>.
FILESNAME_<fn> Optional name to install <fn> as.
FILESBUILD If this variable is defined, then its value will be
used as the default for all FILESBUILD_<fn> variables.
Otherwise, the default will be "no".
FILESBUILD_<fn> A value different from "no" will add the file to the list of
targets to be built by `realall'. Users of that variable
should provide a target to build the file.
BUILDSYMLINKS List of two word items:
lnsrc lntgt
For each lnsrc item, create a symlink named lntgt.
The lntgt symlinks are removed by the cleandir target.
UUDECODE_FILES List of files which are stored as <file>.uue in the source
tree. Each one will be decoded with ${TOOL_UUDECODE}.
The source files have a `.uue' suffix, the generated files do
not.
UUDECODE_FILES_RENAME_<fn>
Rename the output from the decode to the provided name.
*NOTE: These files are simply decoded, with no install or other
rule applying implicitly except being added to the clean
target.
=-=-=-=-= bsd.gcc.mk =-=-=-=-=
The include file <bsd.gcc.mk> computes various parameters related to GCC
support libraries. It defines no targets. <bsd.own.mk> MUST be included
before <bsd.gcc.mk>.
The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each
of which need to know where to find certain GCC support libraries.
The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable,
which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then
the compiler is asked where to find the support libraries, otherwise the
support libraries are found in ${DESTDIR}/usr/lib.
<bsd.gcc.mk> sets the following variables:
_GCC_CRTBEGIN The full path name to crtbegin.o.
_GCC_CRTBEGINS The full path name to crtbeginS.o.
_GCC_CRTEND The full path name to crtend.o.
_GCC_CRTENDS The full path name to crtendS.o.
_GCC_LIBGCCDIR The directory where libgcc.a is located.
=-=-=-=-= bsd.inc.mk =-=-=-=-=
The include file <bsd.inc.mk> defines the includes target and uses the
variables:
INCS The list of include files.
INCSDIR The location to install the include files.
INCSNAME Target name of the include file, if only one; same as
FILESNAME, but for include files.
INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these
are installed in the 'includes' target and not the
(much later) 'install' target.
INCSNAME_<file> The name file <file> should be installed as, if not <file>,
same as FILESNAME_<file>, but for include files.
=-=-=-=-= bsd.info.mk =-=-=-=-=
The include file <bsd.info.mk> is used to generate and install GNU Info
documentation from respective Texinfo source files. It defines three
implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the
following variables:
TEXINFO List of Texinfo source files. Info documentation will
consist of single files with the extension replaced by
.info.
INFOFLAGS Flags to pass to makeinfo. []
=-=-=-=-= bsd.kernobj.mk =-=-=-=-=
The include file <bsd.kernobj.mk> defines variables related to the
location of kernel sources and object directories.
KERNSRCDIR Is the location of the top of the kernel src.
[${_SRC_TOP_}/sys]
KERNARCHDIR Is the location of the machine dependent kernel sources.
[arch/${MACHINE}]
KERNCONFDIR Is where the configuration files for kernels are found.
[${KERNSRCDIR}/${KERNARCHDIR}/conf]
KERNOBJDIR Is the kernel build directory. The kernel GENERIC for
instance will be compiled in ${KERNOBJDIR}/GENERIC.
The default value is
${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile
if it exists or the target 'obj' is being made.
Otherwise the default is
${KERNSRCDIR}/${KERNARCHDIR}/compile.
It is important that Makefiles (such as those under src/distrib) that
wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR}
rather than make assumptions about the location of the compiled kernel.
=-=-=-=-= bsd.kinc.mk =-=-=-=-=
The include file <bsd.kinc.mk> defines the many targets (includes,
subdirectories, etc.), and is used by kernel makefiles to handle
include file installation. It is intended to be included alone, by
kernel Makefiles. It uses similar variables to <bsd.inc.mk>.
Please see <bsd.kinc.mk> for more details, and keep the documentation
in that file up to date.
=-=-=-=-= bsd.lib.mk =-=-=-=-=
The include file <bsd.lib.mk> has support for building libraries. It has
the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
includes, install, lint, and tags. Additionally, it has a checkver target
which checks for installed shared object libraries whose version is greater
that the version of the source. It has a limited number of suffixes,
consistent with the current needs of the BSD tree. <bsd.lib.mk> includes
<bsd.shlib.mk> to get shared library parameters.
It sets/uses the following variables:
LIB The name of the library to build.
LIBDIR Target directory for libraries.
MKARZERO Normally, ar(1) sets the timestamps, uid, gid and
permissions in files inside its archives to those of
the file it was fed. This leads to non-reproduceable
builds. If MKARZERO is set to "yes" (default is "no")
then the "D" flag is passed to ar, causing the
timestamp, uid and gid to be zeroed and the file
permissions to be set to 644. This allows .a files
from different builds to be bit identical.
SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR}
is not "no".
SHLIB_MAJOR
SHLIB_MINOR
SHLIB_TEENY Major, minor, and teeny version numbers of shared library
USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR}
as the path to install shared libraries to.
USE_SHLIBDIR must be defined before <bsd.own.mk> is included.
Default: no
LIBISMODULE If not "no", install as ${LIB}.so (without the "lib" prefix),
and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no
MKPROFILE=no MKSTATICLIB=no".
Default: no
LIBISPRIVATE If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no
MKPROFILE=no", and don't install the (.a) library.
This is useful for "build only" helper libraries.
Default: no
LIBISCXX If not "no", Use ${CXX} instead of ${CC} to link
shared libraries.
This is useful for C++ libraries.
Default: no
LINTLIBDIR Target directory for lint libraries.
LIBGRP Library group.
LIBOWN Library owner.
LIBMODE Library mode.
LDADD Additional loader objects.
MAN The manual pages to be installed (use a .1 - .9 suffix).
NOCHECKVER_<library>
NOCHECKVER If set, disables checking for installed shared object
libraries with versions greater than the source. A
particular library name, without the "lib" prefix, may
be appended to the variable name to disable the check for
only that library.
SRCS List of source files to build the library. Suffix types
.s, .c, and .f are supported. Note, .s files are preferred
to .c files of the same name. (This is not the default for
versions of make.)
LIBDPLIBS A list of the tuples:
libname path-to-srcdir-of-libname
For each tuple;
* LIBDO.libname contains the .OBJDIR of the library
`libname', and if it is not set it is determined
from the srcdir and added to MAKEOVERRIDES (the
latter is to allow for build time optimization).
* LDADD gets -L${LIBDO.libname} -llibname added.
* DPADD gets ${LIBDO.libname}/liblibname.so or
${LIBDO.libname}/liblibname.a added.
The special value "_external" for LIBDO.lib makes the
build system to assume the library comes from outside
of the NetBSD source tree and only causes -llibname
to be added to LDADD.
This variable may be used for individual libraries, as
well as in parent directories to cache common libraries
as a build-time optimization.
The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
if it exists, as well as the include file <bsd.man.mk>.
It has rules for building profiled objects; profiled libraries are
built by default.
Libraries are ranlib'd when made.
=-=-=-=-= bsd.links.mk =-=-=-=-=
The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables
and is included from from <bsd.lib.mk> and <bsd.prog.mk>.
LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log
is used. The defaults may be modified by other bsd.*.mk files which
include bsd.links.mk. In the future, these variables may be replaced
by a method for explicitly recording hard links in a metadata log.
LINKS The list of hard links, consisting of pairs of paths:
source-file target-file
${DESTDIR} is prepended to both paths before linking.
For example, to link /bin/test and /bin/[, use:
LINKS=/bin/test /bin/[
CONFIGLINKS Similar semantics to LINKS, except that the links
are installed by the `configinstall' target,
not the `install' target.
SYMLINKS The list of symbolic links, consisting of pairs of paths:
source-file target-file
${DESTDIR} is only prepended to target-file before linking.
For example, to symlink /usr/bin/tar to /bin/tar resulting
in ${DESTDIR}/usr/bin/tar -> /bin/tar:
SYMLINKS=/bin/tar /usr/bin/tar
CONFIGSYMLINKS Similar semantics to SYMLINKS, except that the symbolic links
are installed by the `configinstall' target,
not the `install' target.
LINKSOWN Link owner. [${BINOWN}]
LINKSGRP Link group. [${BINGRP}]
LINKSMODE Link mode. [${NONBINMODE}]
LINKSOWN_<fn> Link owner of the specific file <fn>.
LINKSGRP_<fn> Link group of the specific file <fn>.
LINKSMODE_<fn> Link mode of the specific file <fn>.
=-=-=-=-= bsd.man.mk =-=-=-=-=
The include file <bsd.man.mk> handles installing manual pages and their
links.
It has a three targets:
catinstall:
Install the preformatted manual pages and their links.
htmlinstall:
Install the HTML manual pages and their links.
maninstall:
Install the manual page sources and their links.
It sets/uses the following variables:
MANDIR Base path for manual installation.
MANGRP Manual group.
MANOWN Manual owner.
MANMODE Manual mode.
MANSUBDIR Subdirectory under the manual page section, i.e. "/vax"
or "/tahoe" for machine specific manual pages.
MAN The manual pages to be installed (use a .1 - .9 suffix).
MLINKS List of manual page links (using a .1 - .9 suffix). The
linked-to file must come first, the linked file second,
and there may be multiple pairs.
The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
it exists.
=-=-=-=-= bsd.obj.mk =-=-=-=-=
The include file <bsd.obj.mk> defines targets related to the creation
and use of separated object and source directories.
If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses
${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if
it exists. Otherwise make(1) looks for the existence of a
subdirectory (or a symlink to a directory) of the source directory
into which built targets should be placed. If an environment variable
named MAKEOBJDIR is set, make(1) uses its value as the name of the
object directory; failing that, make first looks for a subdirectory
named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj".
Object directories are not created automatically by make(1) if they
don't exist; you need to run a separate "make obj". (This will happen
during a top-level build if "MKOBJDIRS" is set to a value other than
"no"). When the source directory is a subdirectory of ${BSDSRCDIR} --
and this is determined by a simple string prefix comparison -- object
directories are created in a separate object directory tree, and a
symlink to the object directory in that tree is created in the source
directory; otherwise, "make obj" assumes that you're not in the main
source tree and that it's not safe to use a separate object tree.
Several variables used by <bsd.obj.mk> control exactly what
directories and links get created during a "make obj":
MAKEOBJDIR If set, this is the component name of the object
directory.
OBJMACHINE If this is set but MAKEOBJDIR is not set, creates
object directories or links named "obj.${MACHINE}";
otherwise, just creates ones named "obj".
USR_OBJMACHINE If set, and the current directory is a subdirectory of
${BSDSRCDIR}, create object directory in the
corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
otherwise, create it in the corresponding subdirectory
of ${BSDOBJDIR}
BUILDID If set, the contents of this variable are appended
to the object directory name. If OBJMACHINE is also
set, ".${BUILDID}" is added after ".${MACHINE}".
=-=-=-=-= bsd.prog.mk =-=-=-=-=
The include file <bsd.prog.mk> handles building programs from one or
more source files, along with their manual pages. It has a limited number
of suffixes, consistent with the current needs of the BSD tree.
<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters.
It has eight targets:
all:
build the program and its manual page. This also
creates a GDB initialization file (.gdbinit) in
the objdir. The .gdbinit file sets the shared library
prefix to ${DESTDIR} to facilitate cross-debugging.
clean:
remove the program, any object files and the files a.out,
Errs, errs, mklog, and ${PROG}.core.
cleandir:
remove all of the files removed by the target clean, as
well as .depend, tags, and any manual pages.
`distclean' is a synonym for `cleandir'.
depend:
make the dependencies for the source files, and store
them in the file .depend.
includes:
install any header files.
install:
install the program and its manual pages; if the Makefile
does not itself define the target install, the targets
beforeinstall and afterinstall may also be used to cause
actions immediately before and after the install target
is executed.
lint:
run lint on the source files
tags:
create a tags file for the source files.
It sets/uses the following variables:
BINGRP Binary group.
BINOWN Binary owner.
BINMODE Binary mode.
CLEANDIRFILES Additional files to remove for the cleandir target.
CLEANFILES Additional files to remove for the clean and cleandir targets.
COPTS Additional flags to the compiler when creating C objects.
COPTS.<fn> Additional flags to the compiler when creating the
C objects for <fn>.
For <fn>.[ly], "<fn>.c" must be used.
CPUFLAGS Additional flags to the compiler/assembler to select
CPU instruction set options, CPU tuning options, etc.
CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>.
For <fn>.[ly], "<fn>.c" must be used.
CPPFLAGS Additional flags to the C pre-processor.
CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>.
For <fn>.[ly], "<fn>.c" must be used.
GDBINIT List of GDB initialization files to add to "source"
directives in the .gdbinit file that is created in the
objdir.
LDADD Additional loader objects. Usually used for libraries.
For example, to load with the compatibility and utility
libraries, use:
LDADD+=-lutil -lcompat
LDFLAGS Additional linker flags (passed to ${CC} during link).
LINKS See <bsd.links.mk>
OBJCOPTS Additional flags to the compiler when creating ObjC objects.
OBJCOPTS.<fn> Additional flags to the compiler when creating the
ObjC objects for <fn>.
For <fn>.[ly], "<fn>.c" must be used.
SYMLINKS See <bsd.links.mk>
MAN Manual pages (should end in .1 - .9). If no MAN variable is
defined, "MAN=${PROG}.1" is assumed.
PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link
time, with the value of this variable as args to paxctl(1).
PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
PROG The name of the program to build. If not supplied, nothing
is built.
PROG_CXX If defined, the name of the program to build. Also
causes <bsd.prog.mk> to link the program with the C++
compiler rather than the C compiler. PROG_CXX overrides
the value of PROG if PROG is also set.
PROGNAME The name that the above program will be installed as, if
different from ${PROG}.
SRCS List of source files to build the program. If SRCS is not
defined, it's assumed to be ${PROG}.c.
DPSRCS List of source files which are needed for generating
dependencies, but are not needed in ${SRCS}.
DPADD Additional dependencies for the program. Usually used for
libraries. For example, to depend on the compatibility and
utility libraries use:
DPADD+=${LIBCOMPAT} ${LIBUTIL}

SHAREDSTRINGS If defined, a new .c.o rule is used that results in shared
strings, using xstr(1). Note that this will not work with
parallel makes.
STRIPFLAG The flag passed to the install program to cause the binary
to be stripped.
SUBDIR A list of subdirectories that should be built as well.
Each of the targets will execute the same target in the
subdirectories.
SCRIPTS A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
These are installed exactly like programs.
SCRIPTSDIR The location to install the scripts. Each script can be
installed to a separate path by setting SCRIPTSDIR_<script>.
SCRIPTSNAME The name that the above program will be installed as, if
different from ${SCRIPTS}. These can be further specialized
by setting SCRIPTSNAME_<script>.
FILES See description of <bsd.files.mk>.
SHLINKDIR Target directory for shared linker. See description of
<bsd.own.mk> for additional information about this variable.
The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
if it exists, as well as the include file <bsd.man.mk>.
Some simple examples:
To build foo from foo.c with a manual page foo.1, use:
PROG= foo
.include <bsd.prog.mk>
To build foo from foo.c with a manual page foo.2, add the line:
MAN= foo.2
If foo does not have a manual page at all, add the line:
MKMAN= no
If foo has multiple source files, add the line:
SRCS= a.c b.c c.c d.c
=-=-=-=-= bsd.rpc.mk =-=-=-=-=
The include file <bsd.rpc.mk> contains a makefile fragment used to
construct source files built by rpcgen.
The following macros may be defined in makefiles which include
<bsd.rpc.mk> in order to control which files get built and how they
are to be built:
RPC_INCS: construct .h file from .x file
RPC_XDRFILES: construct _xdr.c from .x file
(for marshalling/unmarshalling data types)
RPC_SVCFILES: construct _svc.c from .x file
(server-side stubs)
RPC_SVCFLAGS: Additional flags passed to builds of RPC_SVCFILES.
RPC_XDIR: Directory containing .x/.h files
=-=-=-=-= bsd.shlib.mk =-=-=-=-=
The include file <bsd.shlib.mk> computes parameters for shared library
installation and use. It defines no targets. <bsd.own.mk> MUST be
included before <bsd.shlib.mk>.
<bsd.own.mk> sets the following variables, if they are not already defined
(defaults are in brackets):
SHLIBINSTALLDIR If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
instead of ${LIBDIR} as the base path for shared library
installation. [/lib]
SHLIBDIR The path to USE_SHLIBDIR shared libraries to use when building
a program. [/lib for programs in /bin and /sbin, /usr/lib
for all others.]
_LIBSODIR Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
otherwise set to ${LIBDIR}
SHLINKINSTALLDIR Base path for shared linker. [/libexec]
SHLINKDIR Path to use for shared linker when building a program.
[/libexec for programs in /bin and /sbin, /usr/libexec for
all others.]
=-=-=-=-= bsd.subdir.mk =-=-=-=-=
The include file <bsd.subdir.mk> contains the default targets for building
subdirectories. It has the same eight targets as <bsd.prog.mk>: all,
clean, cleandir, depend, includes, install, lint, and tags. It uses the
following variables:
NOSUBDIR If this variable is defined, then the SUBDIR variable
will be ignored and subdirectories will not be processed.
SUBDIR For all of the directories listed in ${SUBDIR}, the
specified directory will be visited and the target made.
As a special case, the use of a token .WAIT as an
entry in SUBDIR acts as a synchronization barrier
when multiple make jobs are run; subdirs before the
.WAIT must complete before any subdirs after .WAIT are
started. See make(1) for some caveats on use of .WAIT
and other special sources.
=-=-=-=-= bsd.sys.mk =-=-=-=-=
The include file <bsd.sys.mk> is used by <bsd.prog.mk> and
<bsd.lib.mk>. It contains overrides that are used when building
the NetBSD source tree.
The following variables control how various files are compiled/built.
(Note that these may be overridden in <bsd.own.mk> if USETOOLS == "yes"):
AR Create, modify, and extract from archives. [ar]
ARFLAGS Options to ${AR}. [rl]
AS Assembler. [as]
AFLAGS Options to ${CC} when compiling or linking .s or .S
assembly source files. []
BUILDSEED GCC uses random numbers when compiling C++ code.
If this option is present, seed the random number
generator based on the value, source file names and
the output file name to make builds more deterministic.
Additional information is available in the GCC
documentation of -frandom-seed.
CC C compiler. [cc]
CFLAGS Options to ${CC}. [Usually -O or -O2]
CPP C Pre-Processor. [cpp]
CPPFLAGS Options to ${CPP}. []
CPUFLAGS Optimization flags for ${CC}. []
CXX C++ compiler. [c++]
CXXFLAGS Options to ${CXX}. [${CFLAGS}]
ELF2ECOFF Convert ELF-format executable to ECOFF. [elf2ecoff]
FC Fortran compiler. [f77]
FFLAGS Options to {$FC}. [-O]
HOST_SH Shell. This must be an absolute path, because it may be
substituted into "#!" lines in scripts. [/bin/sh]
INSTALL install(1) command. [install]
LEX Lexical analyzer. [lex]
LFLAGS Options to ${LEX}. []
LPREFIX Symbol prefix for ${LEX} (see -P option in lex(1)) [yy]
LD Linker. [ld]
LDFLAGS Options to ${CC} during the link process. []
LINT C program verifier. [lint]
LINTFLAGS Options to ${LINT}. [-chapbxzFS]
LORDER List dependencies for object files. [lorder]

OBJC Objective C compiler. [${CC}]
OBJCFLAGS Options to ${OBJC}. [${CFLAGS}]
OBJCOPY Copy and translate object files. [objcopy]
OBJCOPYLIBFLAGS Flags to pass to objcopy when library objects are
being built. [${.TARGET} =~ "*.po" ? -X : -x]
OBJDUMP Display information from object files. [objdump]
RANLIB Generate index to archive. [ranlib]
SIZE List section sizes and total size. [size]
STRIP Discard symbols from object files. [strip]
TSORT Topological sort of a directed graph. [tsort -q]
YACC LALR(1) parser generator. [yacc]
YFLAGS Options to ${YACC}. []
YHEADER If defined, add "-d" to YFLAGS, and add dependencies
from <file>.y to <file>.h and <file>.c, and add
<foo>.h to CLEANFILES.
YPREFIX If defined, add "-p ${YPREFIX}" to YFLAGS.
Other variables of note (incomplete list):
NOGCCERROR If defined, prevents passing certain ${CFLAGS} to GCC
that cause warnings to be fatal, such as:
-Werror -Wa,--fatal-warnings
(The latter being for as(1).)
NOCLANGERROR If defined and clang is used as C compiler, -Werror is not
passed to it.
WARNS Crank up compiler warning options; the distinct levels are:
WARNS=1
WARNS=2
WARNS=3
WARNS=4
WARNS=5
=-=-=-=-= bsd.x11.mk =-=-=-=-=
The include file <bsd.x11.mk> contains parameters and targets for
cross-building X11 from ${X11SRCDIR.xc} / ${X11MITSRCDIR.*}.
It should be included after the general Makefile contents but before
the include files such as <bsd.prog.mk> and <bsd.lib.mk>.
It provides the following targets:
.man.1 .man.3 .man.4 .man.5 .man.7:
If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
these rules convert from X11's manual page source
into an mdoc.old source file.
It sets the following variables:
BINDIR Set to ${X11BINDIR}.
To override, define after including <bsd.x11.mk>
LIBDIR Set to ${X11USRLIBDIR}.
To override, define after including <bsd.x11.mk>
