bmake
This directory contains a port of the BSD make tool (from NetBSD)
I have run it on SunOS,Solaris,HP-UX,AIX,IRIX,FreeBSD and Linux.
Version 3 was re-worked from scratch to better facilitate
importing newer make(1) versions from NetBSD. The original code base
was NetBSD-1.0, so version 3 was built by doing a fresh import of the
NetBSD-1.0 usr.bin/make, adding the autoconf and other portability
patches to sync it with bmake v2, and then NetBSD's make
of Feb 20, 2000 was imported and conflicts dealt with.
NetBSD's make was again imported on June 6 and December 15, 2000.
In 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 prefered 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.
To make much use of bmake you will need the bsd.*.mk macros or my
portable *.mk macros. See
http://www.crufty.net/ftp/pub/sjg/mk.tar.gz
which will be links to the latest versions.
On a non-BSD system, you would want to unpack mk[-YYYYmmdd].tar.gz in
the same directory as bmake (so ./mk and ./bmake exist), and
./bmake/boot-strap will do the rest.
If you want to do it all by hand then read boot-strap first to get the
idea.
Even if you have an earlier version of bmake installed, use boot-strap
to ensure that all goes well.

# NAME:
# boot-strap
#
# SYNOPSIS:
# boot-strap [--"configure_arg" ... ][-s "srcdir"][-m "mksrc"]\\
# ["prefix" ["bmakesrc" ["mksrc"]]]
#
# DESCRIPTION:
# This script is used to configure/build bmake it builds for
# each OS in a subdir to keep the src clean.
# On successful completion it echos commands to put the new
# bmake binary into the /configs tree (if it exists)
# (http://www.crufty.net/FreeWare/configs.html), $prefix/bin
# and a suitable ~/*bin directory.
#
# Options:
#
# -c "rc"
# Pick up settings from "rc".
# We look for '.bmake-boot-strap.rc' before processing
# options.
#
# --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 $prefix/share.
#
# --mksrc "mksrc"
# Indicate where the mk files can be found.
# Default is ./mk or ../mk, set to 'none' to force
# building without "mksrc" but in that case a sys.mk
# needs to exist in the default syspath ($share_dir/mk)
#
# 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="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.

* wins.
* 2) A command to issue to turn off echoing of command lines

* command. This line will not be printed when received from the shell
* 5) A boolean to tell if the shell has the ability to control
* error checking for individual commands.
* 6) The string to turn this checking on.
* 7) The string to turn it off.
* 8) The command-flag to give to cause the shell to start echoing
* commands right away.
* 9) The command-flag to cause the shell to Lib_Exit when an error is
* detected in one of the commands.
*
* Some special stuff goes on if a shell doesn't have error control. In such
* a case, errCheck becomes a printf template for echoing the command,
* 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
* echo "%s\n" as a template.

# NAME:
# mkdeps - generate dependencies
#
# SYNOPSIS:
# mkdeps [options] file ...
#
# DESCRIPTION:
# This script updates "makefile" with dependencies for
# "file"(s). It borrows ideas from various makedepend scripts
# and should be compatible with most.
#
# By default we use grep to extract include file names from
# source files. We source an "rc" file '$Mydir/.${Myname}rc' which
# can contain variable assignments such as:
#.nf
#
# cpp_c=/usr/lib/cpp
# cpp_cc=g++ -E
# ...
#
#.fi
# If the variable 'cpp_$suffix' is set, we use it as our cpp in
# place of grep. The program referenced by these variables are
# expected to produce output like:
#.nf
#
# # 10 \"/usr/include/stdio.h\" 1
#
#.fi
# This allows us to skip most of our processing. For lex,yacc
# and other source files, grep is probably just as quick and
# certainly more portable.
#
# If the "rc" file does not exist, we create it and attempt to
# find cpp or an equivalent cc invocation to assign to 'cpp_c'.

* DESCRIPTION:

*
* Note that signal() is identical to my Signal() routine except
* for checking for recursion. Within libsig, signal() just
* calls Signal().
*
* BUGS:
* This package assumes POSIX signal handling is available and
* NOT implemeneted using these routines. To be safe, we check
* for recursion and abort(3) if detected.
*
* Sadly, on some systems, sigset_t is an array, and we cannot
* test for this via #if sizeof(sigset_t) ..., so unless
* 'SIGSET_T_INT' is defined, we have to assume the worst and use
* memcpy(3) to handle args and return values.
*
* HISTORY:
* These routines originate from BSD, and are derrived from the
* NetBSD 1.1 implementation. They have been seriously hacked to
* make them portable to other systems.
