bmake
*****
This directory contains a port of the BSD make tool (from NetBSD).
Since 1993 I have run it on AIX, BSDi, Darwin, FreeBSD, HP-UX, IRIX,
Linux, Minix, OSF, Solaris, SunOS and even UTS.
Others have run it on many more systems.
Currently each release is tested on NetBSD, FreeBSD, Solaris and Linux.
Since 2003 bmake switched to a date based version (first was 20030714)
which generally represents the date it was last merged with NetBSD's
make. Since then, NetBSD's make is imported within a week of any
interesting changes, so that bmake tracks it very closely.
Building
========
The preferred way to bootstrap bmake is::
./bmake/boot-strap
there are a number of args - most of which get passed to configure,
eg.
::
./bmake/boot-strap --prefix=/opt
see the boot-strap script for details.
For folk that hate to read anything, since 20121212 you can also use
the GNU standard process of::
./configure; make; make install
To make much use of bmake you will need the bsd.*.mk macros or my
portable *.mk macros which are included with bmake since 20121212
and separately available from
http://www.crufty.net/ftp/pub/sjg/mk.tar.gz
which will be links to the latest versions.
Porting
=======
If you encounter a system that bmake does not build or work on *out of
the box*, I welcome patches.
If you can provide access to a suitable machine - even better.
More info can be found at http://www.crufty.net/help/sjg/bmake.htm

# NAME:
# boot-strap
#
# SYNOPSIS:
# boot-strap ["options"]
# boot-strap --prefix=/opt --install
# boot-strap --prefix=$HOME --install-host-target -DWITH_PROG_VERSION
# boot-strap ["options"] op=build
# boot-strap ["options"] op=install
#
# DESCRIPTION:
# This script is used to configure/build bmake it builds for
# each host-target in a different subdir to keep the src clean.
# There is no requirement for an existing make(1).
#
# On successful completion if no '--install' flag is given,
# it echos a command to do installation.
#
# The variable "op" defaults to 'all', and is affected by
# '--install' flag as above.
# Other values include:
#
# configure
# Just run 'configure'
#
# build
# If 'configure' has not been done, do it, then
# run the build script, and finally 'test'.
#
# install
# If 'build' has not been done, do it, 'test' then
# install.
#
# clean
# attempt to clean up
#
# test
# run the unit-tests. Done automatically after 'build'
# and before 'install'.
#
# The above are leveraged by a trivial makefile for the benefit
# of those that have './configure; make; make install' baked
# into them.
#
# Options:
#
# -c "rc"
# Pick up settings from "rc".
# We look for '.bmake-boot-strap.rc' before processing
# options (unless SKIP_RC is set in environment).
#
# --share "share_dir"
# Where to put man pages and mk files.
# If $prefix ends in $HOST_TARGET, and $prefix/../share
# exits, the default will be that rather than $prefix/share.
#
# --mksrc "mksrc"
# Indicate where the mk files can be found.
# Default is $Mydir/mk
#
# --install
# If build and test work, run bmake install.
# BINDIR=$prefix/bin
# SHAREDIR=$prefix/share
#
# --install-host-target
# As for '--install' but BINDIR=$prefix/$HOST_TARGET/bin
# This is useful when $prefix/ is shared by multiple
# machines.
#
# Flags relevant when installing:
#
# -DWITHOUT_INSTALL_MK
# Skip installing mk files.
# By default they will be installed to $prefix/share/mk
#
# -DWITH_PROG_VERSION
# Install 'bmake' as 'bmake-$MAKE_VERSION'
# A symlink will be made as 'bmake' unless
# -DWITHOUT_PROG_LINK is set.
#
# Possibly useful configure_args:
#
# --without-meta
# disable use of meta mode.
#
# --without-filemon
# disable use of filemon(9) which is currently only
# available for NetBSD and FreeBSD.
#
# --with-filemon=ktrace
# on NetBSD or others with fktrace(2), use ktrace
# version of filemon.
#
# --with-filemon="path/to/filemon.h"
# enables use of filemon(9) by meta mode.
#
# --with-machine="machine"
# set "machine" to override that determined by
# machine.sh
#
# --with-force-machine="machine"
# force "machine" even if uname(3) provides a value.
#
# --with-machine_arch="machine_arch"
# set "machine_arch" to override that determined by
# machine.sh
#
# --with-default-sys-path="syspath"
# set an explicit default "syspath" which is where bmake
# will look for sys.mk and friends.

# NAME:
# install.sh - portable version of install(1)
#
# SYNOPSIS:
# install [-CNcs] [-f flags] [-i errs] [-o owner] [-g group] [-m mode] file1 file2 ...
# install -d [-i errs] [-o owner] [-g group] [-m mode] directory ...
#
# DESCRIPTION:
# Compatible with BSD install(1). Except that '-c' is always
# true and we always move an already installed target aside as
# this is important on many systems. Recent BSD install(1)
# versions have a '-b' option for this.
#
#
# OPTIONS:
# -b move previous target file aside (always true).
#
# -B "suffix"
# use "suffix" instead of .old for saving existing target.
#
# -c copy rather than move the file into place (always true).
#
# -C compare. Only install if target is missing or
# different.
#
# -N newer. Only install if target is missing or older.
#
# -s strip target
#
# -o "owner"
# make target owned by "owner"
#
# -g "group"
# make target group owned by "group"
#
# -m "mode"
# set permissions to "mode"
#
# -f "flags"
# Pass "flags" onto chflags(1)
#
# -i "errs"
# Ignore errors from steps indicated by "errs" (``s,o,g,m'').
#
# BUGS:
# The '-i' option is to save your sanity when 'bsd.prog.mk'
# insists on haveing a '-o' "owner" option which is doomed to
# fail on many systems. We ignore '-b', '-B' and '-c' options.

* should echoing be on and ignErr becomes another printf template for
* executing the command while ignoring the return status. Finally errOut
* is a printf template for running the command and causing the shell to
* exit on error. If any of these strings are empty when hasErrCtl is FALSE,
* the command will be executed anyway as is and if it causes an error, so be
* it. Any templates setup to echo the command will escape any '$ ` \ "'i
* characters in the command string to avoid common problems with

# $Id: README,v 1.2 2020/08/19 17:51:53 sjg Exp $
This directory contains some macro's derrived from the NetBSD bsd.*.mk
macros. They have the same names but without the bsd., separate macro
files are needed to ensure we can make them do what we want for
builing things outside of /usr/src. Nearly all the comments below
apply.
# $NetBSD: bsd.README,v 1.18 1997/01/13 00:54:23 mark Exp $
# @(#)bsd.README 5.1 (Berkeley) 5/11/90
This is the README file for the new make "include" files for the BSD
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 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 switch 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.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
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.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
The include file <bsd.man.mk> handles installing manual pages and their
links.
It has a single target:
maninstall:
Install the manual pages 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 files are soft-linked.
The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
it exists.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
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):
BSDSRCDIR The real path to the system sources, so that 'make obj'
will work correctly. [/usr/src]
BSDOBJDIR The real path to the system 'obj' tree, so that 'make obj'
will work correctly. [/usr/obj]
BINGRP Binary group. [bin]
BINOWN Binary owner. [bin]
BINMODE Binary mode. [555]
NONBINMODE Mode for non-executable files. [444]
MANDIR Base path for manual installation. [/usr/share/man/cat]
MANGRP Manual group. [bin]
MANOWN Manual owner. [bin]
MANMODE Manual mode. [${NONBINMODE}]
LIBDIR Base path for library installation. [/usr/lib]
LINTLIBDIR Base path for lint(1) library installation. [/usr/libdata/lint]
LIBGRP Library group. [${BINGRP}]
LIBOWN Library owner. [${BINOWN}]
LIBMODE Library mode. [${NONBINMODE}]
DOCDIR Base path for system documentation (e.g. PSD, USD, etc.)
installation. [/usr/share/doc]
DOCGRP Documentation group. [bin]
DOCOWN Documentation owner. [bin]
DOCMODE Documentation mode. [${NONBINMODE}]
NLSDIR Base path for National Language Support files installation.
[/usr/share/nls]
NLSGRP National Language Support files group. [bin]
NLSOWN National Language Support files owner. [bin]
NLSMODE National Language Support files mode. [${NONBINMODE}]
STRIP The flag passed to the install program to cause the binary
to be stripped. This is to be used when building your
own install script so that the entire system can be made
stripped/not-stripped using a single knob. [-s]
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]
Additionally, the following variables may be set by bsd.own.mk or in a
make configuration file to modify the behaviour of the system build
process (default values are in brackets along with comments, if set by
bsd.own.mk):
EXPORTABLE_SYSTEM
Do not build /usr/src/domestic, even if it is present.
SKEY Compile in support for S/key authentication. [yes, set
unconditionally]
KERBEROS Compile in support for Kerberos 4 authentication.
KERBEROS5 Compile in support for Kerberos 5 authentication.
MANZ Compress manual pages at installation time.
SYS_INCLUDE Copy or symlink kernel include files into /usr/include.
Possible values are "symlinks" or "copies" (which is
the same as the variable being unset).
NOPROFILE Do not build profiled versions of system libraries
NOPIC Do not build PIC versions of system libraries, and
do not build shared libraries. [set if ${MACHINE_ARCH}
is "mips", "vax", "alpha" or "arm32", unset otherwise.]
NOLINT Do not build lint libraries. [set, set unconditionally]
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.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
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.
It has eight targets:
all:
build the program and its manual page
clean:
remove the program, any object files and the files a.out,
Errs, errs, mklog, and core.
cleandir:
remove all of the files removed by the target clean, as
well as .depend, tags, and any manual pages.
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.
CLEANFILES Additional files to remove for the clean and cleandir targets.
COPTS Additional flags to the compiler when creating C objects.
HIDEGAME If HIDEGAME is defined, the binary is installed in
/usr/games/hide, and a symbolic link is created to
/usr/games/dm.
LDADD Additional loader objects. Usually used for libraries.
For example, to load with the compatibility and utility
libraries, use:
LDADD+=-lutil -lcompat
LDFLAGS Additional loader flags.
LINKS The list of binary links; should be full pathnames, the
linked-to file coming first, followed by the linked
file. The files are hard-linked. For example, to link
/bin/test and /bin/[, use:
LINKS= ${DESTDIR}/bin/test ${DESTDIR}/bin/[
MAN Manual pages (should end in .1 - .9). If no MAN variable is
defined, "MAN=${PROG}.1" is assumed.
PROG The name of the program to build. If not supplied, nothing
is built.
SRCS List of source files to build the program. If PROG is not
defined, it's assumed to be ${PROG}.c.
DPADD Additional dependencies for the program. Usually used for
libraries. For example, to depend on the compatibility and
utility libraries use:
DPADD+=${LIBCOMPAT} ${LIBUTIL}
The following libraries are predefined for DPADD:
LIBC /lib/libc.a
LIBCOMPAT /usr/lib/libcompat.a
LIBCRYPT /usr/lib/libcrypt.a
LIBCURSES /usr/lib/libcurses.a
LIBDBM /usr/lib/libdbm.a
LIBDES /usr/lib/libdes.a
LIBL /usr/lib/libl.a
LIBKDB /usr/lib/libkdb.a
LIBKRB /usr/lib/libkrb.a
LIBKVM /usr/lib/libkvm.a
LIBM /usr/lib/libm.a
LIBMP /usr/lib/libmp.a
LIBPC /usr/lib/libpc.a
LIBPLOT /usr/lib/libplot.a
LIBRPC /usr/lib/sunrpc.a
LIBTERM /usr/lib/libterm.a
LIBUTIL /usr/lib/libutil.a
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.
STRIP 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.
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:
NOMAN= noman
If foo has multiple source files, add the line:
SRCS= a.c b.c c.c d.c
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
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. For all of
the directories listed in the variable SUBDIRS, the specified directory
will be visited and the target made. There is also a default target which
allows the command "make subdir" where subdir is any directory listed in
the variable SUBDIRS.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
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. For instance, if "PARALLEL" is defined by
the program/library Makefile, it includes a set of rules for lex and
yacc that allow multiple lex and yacc targets to be built in parallel.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
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. It has a limited number of suffixes,
consistent with the current needs of the BSD tree.
It sets/uses the following variables:
LIB The name of the library to build.
LIBDIR Target directory for libraries.
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).
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.)
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.

#
# This makefile deals with the updating of STATIC_DIRDEPS_CACHE.
# Some targets are so huge that computing dirdeps takes a significant
# amount of time. For such targets a STATIC_DIRDEPS_CACHE can make
# sense.
#
# If the target is represented by targets/pseudo/production
# it's normal DIRDEPS would be in
# targets/pseudo/production/Makefile.depend
# and STATIC_DIRDEPS_CACHE would be
# targets/pseudo/production/Makefile.dirdeps.cache
# which is simply initialized by copying dirdeps.cache.production
# from $OBJTOP
#
# When dirdeps-targets.mk is initializing DIRDEPS it will look for
# Makefile.dirdeps.cache and unless told not to
# (MK_STATIC_DIRDEPS_CACHE=no) will use it as DIRDEPS_CACHE.
#
# If MK_STATIC_DIRDEPS_CACHE_UPDATE is "yes", then this makefile
# comes into play.
#
# We usually get included from local.dirdeps.mk
# as well as Makefile.depend of RELDIR with a static Makefile.dirdeps.cache
#
# If we see that STATIC_DIRDEPS_CACHE is in use, we need to hook a
# cache-update target into the build to regenerate dirdeps.cache
# in parallel with the rest of the build.
# If MK_STATIC_DIRDEPS_CACHE_UPDATE_IMMEDIATE is "yes" we update
# STATIC_DIRDEPS_CACHE as soon as the update is ready,
# otherwise it will be done at the end of the build.
#
# If STATIC_DIRDEPS_CACHE is not in use, but a DIRDEPS_CACHE is,
# then we need do nothing except export STATIC_DIRDEPS_CACHE and
# DYNAMIC_DIRDEPS_CACHE for use when we are include during the visit
# to the ultimate target (targets/pseudo/production).
#
# Regardless of which happens, when included at .MAKE.LEVEL > 0
# for a target other than cache-update we simply copy
# DYNAMIC_DIRDEPS_CACHE to STATIC_DIRDEPS_CACHE with some optional

# The basic idea is that we have a list of directories in

# When asked to make 'foo' we look for any directory named 'foo'
# under DIRDEPS_TARGETS_DIRS.
# We then search those dirs for any Makefile.depend*
# Finally we select any that match conditions like REQUESTED_MACHINE
# or TARGET_SPEC and initialize DIRDEPS accordingly.
#
# We will check each of the initial DIRDEPS for Makefile.dirdeps.options
# and include any found.
# This makes it feasible to tweak options like MK_DIRDEPS_CACHE
# for a specific target.
#
# If MK_STATIC_DIRDEPS_CACHE is defined we will check if the
# initial DIRDEPS has a static cache (Makefile.dirdeps.cache).

# Much of the complexity here is for supporting cross-building.
# If a tree does not support that, simply using plain Makefile.depend
# should provide sufficient clue.
# Otherwise the recommendation is to use Makefile.depend.${MACHINE}
# as expected below.
# Note: this file gets multiply included.
# This is what we do with DIRDEPS
# DIRDEPS:
# This is a list of directories - relative to SRCTOP, it is
# normally only of interest to .MAKE.LEVEL 0.
# In some cases the entry may be qualified with a .<machine>
# or .<target_spec> suffix (see TARGET_SPEC_VARS below),
# for example to force building something for the pseudo
# machines "host" or "common" regardless of current ${MACHINE}.
#
# All unqualified entries end up being qualified with .${TARGET_SPEC}
# and partially qualified (if TARGET_SPEC_VARS has multiple
# entries) are also expanded to a full .<target_spec>.
# The _DIRDEP_USE target uses the suffix to set TARGET_SPEC
# correctly when visiting each entry.
#
# The fully qualified directory entries are used to construct a
# dependency graph that will drive the build later.
#
# Also, for each fully qualified directory target, we will search
# using ${.MAKE.DEPENDFILE_PREFERENCE} to find additional
# dependencies. We use Makefile.depend (default value for
# .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to
# distinguish them from others.
#
# Before each Makefile.depend file is read, we set
# DEP_RELDIR to be the RELDIR (path relative to SRCTOP) for
# its directory, and DEP_MACHINE etc according to the .<target_spec>
# represented by the suffix of the corresponding target.
#
# Since each Makefile.depend file includes dirdeps.mk, this
# processing is recursive and results in .MAKE.LEVEL 0 learning the
# dependencies of the tree wrt the initial directory (_DEP_RELDIR).
#
# TARGET_SPEC_VARS
# The default value is just MACHINE, and for most environments
# this is sufficient. The _DIRDEP_USE target actually sets
# both MACHINE and TARGET_SPEC to the suffix of the current
# target so that in the general case TARGET_SPEC can be ignored.
#
# If more than MACHINE is needed then sys.mk needs to decompose
# TARGET_SPEC and set the relevant variables accordingly.
# It is important that MACHINE be included in and actually be
# the first member of TARGET_SPEC_VARS. This allows other
# variables to be considered optional, and some of the treatment
# below relies on MACHINE being the first entry.
# Note: TARGET_SPEC cannot contain any '.'s so the target
# triple used by compiler folk won't work (directly anyway).
#
# For example:
#
# # Always list MACHINE first,
# # other variables might be optional.

# .if ${TARGET_SPEC:Uno:M*,*} != ""
# _tspec := ${TARGET_SPEC:S/,/ /g}

# DESCRIPTION:
# This makefile manages a number of variables that simplify
# dealing with libs in a build.
#
# Primary inputs are DPLIBS, DPADD and SRC_LIBS:
#
# DPLIBS
# List of LIB* that we will actually link with
# should be in correct link order.
# DPLIBS is a short-cut to ensure that DPADD and LDADD are
# kept in sync.
#
# DPADD List of LIB* that should already be built.
#
# SRC_LIBS
# List of LIB* that we want headers from, we do *not*
# require that such libs have been built.
#
# The above all get added to DPMAGIC_LIBS which is what we
# process.
#
# We expect LIB* to be set to absolute path of a library -
# suitable for putting in DPADD.
# eg.
#
# LIBC ?= ${OBJTOP}/lib/libc/libc.a
#
# From such a path we can derrive a number of other variables
# for which we can supply sensible default values.
# We name all these variables for the basename of the library
# (libc in our example above -- ${__lib:T:R} in below):
#
# LDADD_${__lib:T:R}:
# What should be added to LDADD (eg -lc)
#
# OBJ_${__lib:T:R}:
# This is trivial - just the dirname of the built library.
#
# SRC_${__lib:T:R}:
# Where the src for ${__lib} is, if LIB* is set as above
# we can simply substitute ${SRCTOP} for ${OBJTOP} in
# the dirname.
#
# INCLUDES_${__lib:T:R}:
# What should be added to CFLAGS
#
# If the directory ${SRC_${__lib:T:R}}/h exists we will
# only add -I${SRC_${__lib:T:R}}/h on the basis that
# this is where the public api is kept.
#
# Otherwise default will be -I${OBJ_${__lib:T:R}}
# -I${SRC_${__lib:T:R}}
#
# Note much of the above is skipped for staged libs
# eg.
# LIBC ?= ${STAGE_OBJTOP}/usr/lib/libc.a
#
# Since we can safely assume that -I${STAGE_OBJTOP}/usr/include
# and -L${STAGE_OBJTOP}/usr/lib are sufficient, and we should
# have no need of anything else.

# NAME:
# install-mk - install mk files
#
# SYNOPSIS:
# install-mk [options] [var=val] [dest]
#
# DESCRIPTION:
# This tool installs mk files in a semi-intelligent manner into
# "dest".
#
# Options:
#
# -n just say what we want to do, but don't touch anything.
#
# -f use -f when copying sys,mk.
#
# -v be verbose
#
# -q be quiet
#
# -m "mode"
# Use "mode" for installed files (444).
#
# -o "owner"
# Use "owner" for installed files.
#
# -g "group"
# Use "group" for installed files.
#
# var=val
# Set "var" to "val". See below.
#
# All our *.mk files are copied to "dest" with appropriate
# ownership and permissions.
#
# By default if a sys.mk can be found in a standard location
# (that bmake will find) then no sys.mk will be put in "dest".
#
# SKIP_SYS_MK:
# If set, we will avoid installing our 'sys.mk'
# This is probably a bad idea.
#
# SKIP_BSD_MK:
# If set, we will skip making bsd.*.mk links to *.mk
#
# sys.mk:
#
# By default (and provided we are not installing to the system
# mk dir - '/usr/share/mk') we install our own 'sys.mk' which
# includes a sys specific file, or a generic one.

"""
This script parses each "meta" file and extracts the
information needed to deduce build and src dependencies.
It works much the same as the original shell script, but is
*much* more efficient.
The parsing work is handled by the class MetaFile.
We only pay attention to a subset of the information in the
"meta" files. Specifically:
'CWD' to initialize our notion.
'C' to track chdir(2) on a per process basis
'R' files read are what we really care about.
directories read, provide a clue to resolving
subsequent relative paths. That is if we cannot find
them relative to 'cwd', we check relative to the last
dir read.
'W' files opened for write or read-write,
for filemon V3 and earlier.
'E' files executed.
'L' files linked
'V' the filemon version, this record is used as a clue
that we have reached the interesting bit.

# NAME:
# meta2deps.sh - extract useful info from .meta files
#
# SYNOPSIS:
# meta2deps.sh SB="SB" "meta" ...
#
# DESCRIPTION:
# This script looks each "meta" file and extracts the
# information needed to deduce build and src dependencies.
#
# To do this, we extract the 'CWD' record as well as all the
# syscall traces which describe 'R'ead, 'C'hdir and 'E'xec
# syscalls.
#
# The typical meta file looks like::
#.nf
#
# # Meta data file "path"
# CMD "command-line"
# CWD "cwd"
# TARGET "target"
# -- command output --
# -- filemon acquired metadata --
# # buildmon version 2
# V 2
# E "pid" "path"
# R "pid" "path"
# C "pid" "cwd"
# R "pid" "path"
# X "pid" "status"
#.fi
#
# The fact that all the syscall entry lines start with a single
# character make these files quite easy to process using sed(1).
#
# To simplify the logic the 'CWD' line is made to look like a
# normal 'C'hdir entry, and "cwd" is remembered so that it can
# be prefixed to any "path" which is not absolute.
#
# If the "path" being read ends in '.srcrel' it is the content
# of (actually the first line of) that file that we are
# interested in.
#
# Any "path" which lies outside of the sandbox "SB" is generally
# not of interest and is ignored.
#
# The output, is a set of absolute paths with "SB" like:
#.nf
#
# $SB/obj-i386/bsd/gnu/lib/csu
# $SB/obj-i386/bsd/gnu/lib/libgcc
# $SB/obj-i386/bsd/include
# $SB/obj-i386/bsd/lib/csu/i386-elf
# $SB/obj-i386/bsd/lib/libc
# $SB/src/bsd/include
# $SB/src/bsd/sys/i386/include
# $SB/src/bsd/sys/sys
# $SB/src/pan-release/rtsock
# $SB/src/pfe-shared/include/jnx
#.fi
#
# Which can then be further processed by 'gendirdeps.mk'
#
# If we are passed 'DPDEPS='"dpdeps", then for each src file
# outside of "CURDIR" we read, we output a line like:
#.nf
#
# DPDEPS_$path += $RELDIR
#.fi
#
# with "$path" geting turned into reldir's, so that we can end
# up with a list of all the directories which depend on each src
# file in another directory. This can allow for efficient yet
# complete testing of changes.

mk-files
********
The term ``mk-files`` refers to a collection of ``*.mk`` files.
You need bmake_ or a *recent* NetBSD_ make.
If in doubt use bmake_.
Introduction
============
Many years ago, when building large software projects, I used GNU make
(or my own patched version of it), and had developed a set of macros
to simplify developing complex build trees.
Since the early 90's my main development machines, run BSD
(NetBSD_ to be precise, and more recently FreeBSD), and the BSD source
tree is good example of a large software project.
It quickly became clear that ``/usr/share/mk/*.mk`` were a great
model, but at the time were quite tightly linked to building the BSD tree.
Much as I liked using NetBSD, my customers were more likely to be
using SunOS, HP-UX etc, so I started on bmake_ and a portable collection
of mk-files (mk.tar.gz_). NetBSD provided much of the original structure.
Since then I've added a lot of features to NetBSD's make and hence to
bmake which is kept closely in sync. The mk-files however have
diverged quite a bit, though ideas are still picked up from NetBSD
and FreeBSD.
Basics
------
The BSD build model is very simple. A directory produces one
component, which is generally either a library or a program.
Library makefiles include ``lib.mk`` and programs include ``prog.mk``
and they *do the right thing*.
A simple library makefile might look like::
LIB = sig
SRCS = \
sigaction.c \
sigcompat.c \
sighdl.c
.include <lib.mk>
a simple program makefile::
PROG = cat
SRCS = cat.c
.include <prog.mk>
in such cases even the ``SRCS`` line is unnecessary as ``prog.mk``
will default it to ``${PROG}.c``.
It is the sensible use of defaults and the plethora of macro modifiers
provided by bmake_ that allow simple makefiles such as the above to
*just work* on many different systems.
mk-files
========
This section provides a brief description of some of the ``*.mk``
files.
sys.mk
------
When bmake starts, it looks for ``sys.mk`` and reads it before doing
anything else. Thus, this is the place to setup the environment for
everyone else.
In this distribution, ``sys.mk`` avoids doing anything platform dependent.
It is quite short, and includes a number of other files (which may or
may not exists)
sys.env.mk
If it exists, is expected to do things like conditioning the
environment. Since it will only be included by the initial
instance of bmake, it should ``.export`` anything that
sub-makes might need.
examples/sys.clean-env.mk
An example of how to clean the environment.
See the file for all the details::
.if ${MAKE_VERSION} >= 20100606 && ${.MAKE.LEVEL} == 0
# we save any env var that starts with these
MAKE_SAVE_ENV_PREFIX += SB MK MAKE MACHINE NEED_ CCACHE DISTCC USE_ SSH
MAKE_SAVE_ENV_VARS += \
PATH HOME USER LOGNAME \
SRCTOP OBJTOP OBJROOT \
${_env_vars}
_env_vars != env | egrep '^(${MAKE_SAVE_ENV_PREFIX:ts|})' | sed 's,=.*,,'; echo
_export_list =
.for v in ${MAKE_SAVE_ENV_VARS:O:u}
.if !empty($v)
_export_list += $v
$v := ${$v}
.endif
.endfor
# now clobber the environment
.unexport-env
# list of vars that we handle specially below
_tricky_env_vars = MAKEOBJDIR
# export our selection - sans tricky ones
.export ${_export_list:${_tricky_env_vars:${M_ListToSkip}}}
# this next bit may need tweaking
.if defined(MAKEOBJDIR)
srctop := ${SRCTOP:U${SB_SRC:U${SB}/src}}
objroot := ${OBJROOT:U${SB_OBJROOT:U${SB}/${SB_OBJPREFIX}}}
# we'll take care of MACHINE below
objtop := ${OBJTOP:U${objroot}${MACHINE}}
.if !empty(objtop)
# we would normally want something like (/bin/sh):
# MAKEOBJDIR="\${.CURDIR:S,${SRCTOP},${OBJROOT}\${MACHINE},}"
# the $$ below is how we achieve the same result here.
# since everything saved from the environment above
# has run through := we need to compensate for ${MACHINE}
MAKEOBJDIR = $${.CURDIR:S,${srctop},${objtop:S,${MACHINE},\${MACHINE},},}
# export these as-is, and do not track...
.export-env ${_tricky_env_vars}
# now evaluate for ourselves
.for v in ${_tricky_env_vars}
$v := ${$v}
.endfor
.endif
.endif
.endif
host-target.mk
Is used to set macros like ``HOST_TARGET``, ``HOST_OS`` and
``host_os`` which are used to find the next step.
sys/\*.mk
Platform specific additions, such as ``Darwin.mk`` or ``SunOS.mk``
set things like ``HOST_LIBEXT = .dylib`` for Darwin or
``SHLIB_FULLVERSION = ${SHLIB_MAJOR}`` for SunOS 5.
If there is no OS specific file, ``sys/Generic.mk`` is used.
local.sys.mk
Any ``local.*.mk`` file is not part of the distribution.
This provides a hook for sites to do extra setup without
having to edit the distributed files.
The above arrangement makes it easy for the mk files to be part of a
src tree on an NFS volume and to allow building on multiple platforms.
lib.mk
------
This file is used to build a number of different libraries from the
same SRCS.
lib${LIB}.a
An archive lib of ``.o`` files, this is the default
lib${LIB}_p.a
A profiled lib of ``.po`` files.
Still an archive lib, but all the objects are built with
profiling in mind - hence the different extension.
It is skipped if ``MKPROFILE`` is "no".
lib${LIB}_pic.a
An archive of ``.so`` objects compiled for relocation.
On NetBSD this is the input to ``lib${LIB}.${LD_so}``, it is
skipped if ``MKPICLIB`` is "no".
lib${LIB}.${LD_so}
A shared library. The value of ``LD_so`` is very platform
specific. For example::
# SunOS 5 and most other ELF systems
libsslfd.so.1
# Darwin
libsslfd.1.dylib
This library will only be built if ``SHLIB_MAJOR`` has
a value, and ``MKPIC`` is not set to "no".
There is a lot of platform specific tweaking in ``lib.mk``, largely the
result of the original distributions trying to avoid interfering with
the system's ``sys.mk``.
libnames.mk
-----------
This is included by both ``prog.mk`` and ``lib.mk`` and tries to
include ``*.libnames.mk`` of which:
local.libnames.mk
does not exist unless you create it. It is a handy way for you
to customize without touching the distributed files.
For example, on a test machine I needed to build openssl but
not install it, so put the following in ``local.libnames.mk``::
.if ${host_os} == "sunos"
LIBCRYPTO = ${OBJTOP}/openssl/lib/crypto/libcrypto${DLIBEXT}
LIBSSL = ${OBJTOP}/openssl/lib/ssl/libssl${DLIBEXT}
INCLUDES_libcrypto = -I${OBJ_libcrypto}
.endif
The makefile created an openssl dir in ``${OBJ_libcrypto}`` to
gather all the headers. dpadd.mk_ did the rest.
host.libnames.mk
contains logic to find any libs named in ``HOST_LIBS`` in
``HOST_LIBDIRS``.
Each file above gets an opportunity to define things like::
LIBSSLFD ?= ${OBJTOP}/ssl/lib/sslfd/libsslfd${DLIBEXT}
INCLUDES_libsslfd = -I${SRC_libsslfd}/h -I${OBJ_libslfd}
these are used by dpadd.mk_ and will be explained below.
dpadd.mk
--------
This file looks like line noise, and is best considered read-only.
However it provides some very useful functionality, which simplifies the build.
Makefiles can use the LIB* macros defined via libnames.mk_ or anywhere
else in various ways::
# indicate that we need to include headers from LIBCRYPTO
# this would result in ${INCLUDES_libcrypto} being added to CFLAGS.
SRC_LIBS += ${LIBCRYPTO}
# indicate that libsslfd must be built already.
# it also has the same effect as SRC_LIBS
DPADD += ${LIBSSLFD}
# indicate that not only must libsslfd be built,
# but that we need to link with it.
# this is almost exactly equivalent to
# DPADD += ${LIBSSLFD}
# LDADD += -L${LIBSSLFD:H} -lsslfd
# and mostly serves to ensure that DPADD and LDADD are in sync.
DPLIBS += ${LIBSSLFD}
Any library (referenced by its full path) in any of the above, is
added to ``DPMAGIC_LIBS`` with the following results, for each lib *foo*.
SRC_libfoo
Is set to indicate where the src for libfoo is.
By default it is derived from ``LIBFOO`` by replacing
``${OBJTOP}`` with ``${SRCTOP}``.
OBJ_libfoo
Not very exciting, is just the dir where libfoo lives.
INCLUDES_libfoo
What to add to ``CFLAGS`` to find the public headers.
The default varies. If ``${SRC_libfoo}/h`` exists, it is assumed
to be the home of all public headers and thus the default is
``-I${SRC_libfoo}/h``
Otherwise we make no assumptions and the default is
``-I${SRC_libfoo} -I${OBJ_libfoo}``
LDADD_libfoo
This only applies to libs reference via ``DPLIBS``.
The default is ``-lfoo``, ``LDADD_*`` provides a hook to
instantiate other linker flags at the appropriate point
without losing the benfits of ``DPLIBS``.
prog.mk
-------
Compiles the specified SRCS and links them and the nominated libraries
into a program. Prog makefiles usually need to list the libraries
that need to be linked. We prefer use of ``DPLIBS`` but the more
traditional ``DPADD`` and ``LDADD`` work just as well.
That is::
DPLIBS += ${LIBCRYPTO}
is equivalent to::
DPADD += ${LIBCRYPTO}
LDADD += -lcrypto
obj.mk
------
One of the cool aspects of BSD make, is its support for separating
object files from the src tree. This is also the source of much
confusion to some.
Traditionally one had to do a separate ``make obj`` pass through the
tree. If ``MKOBJDIRS`` is "auto", we include auto.obj.mk_.
auto.obj.mk
-----------
This leverages the ``.OBJDIR`` target introduced some years ago to
NetBSD make, to automatically create the desired object dir.
subdir.mk
---------
This is the traditional means of walking the tree. A makefile sets
``SUBDIR`` to the list of sub-dirs to visit.
If ``SUBDIR_MUST_EXIST`` is set, missing directories cause an error,
otherwise a warning is issued. If you don't even want the warning,
set ``MISSING_DIR=continue``.
Traditionally, ``subdir.mk`` prints clues as it visits each subdir::
===> ssl
===> ssl/lib
===> ssl/lib/sslfd
you can suppress that - or enhance it by setting ``ECHO_DIR``::
# suppress subdir noise
ECHO_DIR=:
# print time stamps
ECHO_DIR=echo @ `date "+%s [%Y-%m-%d %T] "`
links.mk
--------
Provides rules for processing lists of ``LINKS`` and ``SYMLINKS``.
Each is expected to be a list of ``link`` and ``target`` pairs
(``link`` -> ``target``).
The logic is generally in a ``_*_SCRIPT`` which is referenced in a
``_*_USE`` (``.USE``) target.
The ``_BUILD_*`` forms are identical, but do not use ``${DESTDIR}``
and so are useful for creating symlinks during the build phase.
For example::
SYMLINKS += ${.CURDIR}/${MACHINE_ARCH}/include machine
header_links: _BUILD_SYMLINKS_USE
md.o: header_links
would create a symlink called ``machine`` in ``${.OBJDIR}`` pointing to
``${.CURDIR}/${MACHINE_ARCH}/include`` before compiling ``md.o``
autoconf.mk
-----------
Deals with running (or generating) GNU autoconf ``configure`` scripts.
dep.mk
------
Deals with collecting dependencies. Another useful feature of BSD
make is the separation of this sort of information into a ``.depend``
file. ``MKDEP`` needs to point to a suitable tool (like mkdeps.sh_)
If ``USE_AUTODEP_MK`` is "yes" includes autodep.mk_
autodep.mk
----------
Leverages the ``-MD`` feature of recent GCC to collect dependency
information as a side effect of compilation. With this GCC puts
dependency info into a ``.d`` file.
Unfortunately GCC bases the name of the ``.d`` file on the name of the
input rather than the output file, which causes problems when the same
source is compiled different ways. The latest GCC supports ``-MF`` to
name the ``.d`` file and ``-MT`` to control the name to put as the
dependent.
Recent bmake allows dependencies for the ``.END`` target (run at the
end if everything was successful), and ``autodep.mk`` uses this to
post process the ``.d`` files into ``.depend``.
auto.dep.mk
-----------
A much simpler implementation than autodep.mk_ it uses
``-MF ${.TARGET:T}.d``
to avoid possible conflicts during parallel builds.
This precludes the use of suffix rules to drive ``make depend``, so
dep.mk_ handles that if specifically requested.
options.mk
----------
Inspired by FreeBSD's ``bsd.own.mk`` more flexible.
FreeBSD now have similar functionality in ``bsd.mkopt.mk``.
It allows users to express their intent with respect to options
``MK_*`` by setting ``WITH_*`` or ``WITHOUT_*``.
Note: ``WITHOUT_*`` wins if both are set, and makefiles can set
``NO_*`` to say they cannot handle that option, or even ``MK_*`` if
they really need to.
own.mk
------
Normally included by ``init.mk`` (included by ``lib.mk`` and
``prog.mk`` etc), sets macros for default ownership etc.
It includes ``${MAKECONF}`` if it is defined and exists.
ldorder.mk
----------
Leverages ``bmake`` to compute optimal link order for libraries.
This works nicely and makes refactoring a breeze - so long as you
have not (or few) cicular dependencies between libraries.
man.mk
------
Deals with man pages.
warnings.mk
-----------
This provides a means of fine grained control over warnings on a per
``${MACHINE}`` or even file basis.
A makefile sets ``WARNINGS_SET`` to name a list of warnings
and individual ``W_*`` macros can be used to tweak them.
For example::
WARNINGS_SET = HIGH
W_unused_sparc = -Wno-unused
would add all the warnings in ``${HIGH_WARNINGS}`` to CFLAGS, but
on sparc, ``-Wno-unused`` would replace ``-Wunused``.
You should never need to edit ``warnings.mk``, it will include
``warnings-sets.mk`` if it exists and you use that to make any local
customizations.
rst2htm.mk
----------
Logic to simplify generating HTML (and PDF) documents from ReStructuredText.
cython.mk
---------
Logic to build Python C interface modules using Cython_
.. _Cython: http://www.cython.org/
Meta mode
=========
The 20110505 and later versions of ``mk-files`` include a number of
makefiles contributed by Juniper Networks, Inc.
These allow the latest version of bmake_ to run in `meta mode`_
see `dirdeps.mk`_
.. _`dirdeps.mk`: /help/sjg/dirdeps.htm
.. _`meta mode`: bmake-meta-mode.htm
Install
=======
You can use the content of mk.tar.gz_ without installing at all.
The script ``install-mk`` takes care of copying ``*.mk`` into a
destination directory, and unless told not to, create ``bsd.*.mk`` links
for ``lib.mk`` etc.
If you just want to create the ``bsd.*.mk`` links in the directory
where you unpacked the tar file, you can::
./mk/install-mk ./mk
