2# NAME:
3# boot-strap
4#
5# SYNOPSIS:
6# boot-strap ["options"]
7# boot-strap --prefix=/opt --install
8# boot-strap --prefix=$HOME --install-host-target -DWITH_PROG_VERSION
9# boot-strap ["options"] op=build
10# boot-strap ["options"] op=install
11#
12# DESCRIPTION:
13# This script is used to configure/build bmake it builds for
14# each host-target in a different subdir to keep the src clean.
15# There is no requirement for an existing make(1).
16#
17# On successful completion if no '--install' flag is given,
18# it echos a command to do installation.
19#
20# The variable "op" defaults to 'all', and is affected by
21# '--install' flag as above.
22# Other values include:
23#
24# configure
25# Just run 'configure'
26#
27# build
28# If 'configure' has not been done, do it, then
29# run the build script, and finally 'test'.
30#
31# install
32# If 'build' has not been done, do it, 'test' then
33# install.
34#
35# clean
36# attempt to clean up
37#
38# test
39# run the unit-tests. Done automatically after 'build'
40# and before 'install'.
41#
42# The above are leveraged by a trivial makefile for the benefit
43# of those that have './configure; make; make install' baked
44# into them.
45#
46# Options:
47#
48# -c "rc"
49# Pick up settings from "rc".
50# We look for '.bmake-boot-strap.rc' before processing
51# options (unless SKIP_RC is set in environment).
52#
53# --share "share_dir"
54# Where to put man pages and mk files.
55# If $prefix ends in $HOST_TARGET, and $prefix/../share
56# exits, the default will be that rather than $prefix/share.
57#
58# --mksrc "mksrc"
59# Indicate where the mk files can be found.
60# Default is $Mydir/mk
61#
62# --install
63# If build and test work, run bmake install.
64# BINDIR=$prefix/bin
65# SHAREDIR=$prefix/share
66#
67# --install-host-target
68# As for '--install' but BINDIR=$prefix/$HOST_TARGET/bin
69# This is useful when $prefix/ is shared by multiple
70# machines.
71#
72# Flags relevant when installing:
73#
74# -DWITHOUT_INSTALL_MK
75# Skip installing mk files.
76# By default they will be installed to $prefix/share/mk
77#
78# -DWITH_PROG_VERSION
79# Install 'bmake' as 'bmake-$MAKE_VERSION'
80# A symlink will be made as 'bmake' unless
81# -DWITHOUT_PROG_LINK is set.
82#
83# Possibly useful configure_args:
84#
85# --without-meta
86# disable use of meta mode.
87#
88# --without-filemon
89# disable use of filemon(9) which is currently only
90# available for NetBSD and FreeBSD.
91#
92# --with-filemon="path/to/filemon.h"
93# enables use of filemon(9) by meta mode.
94#
95# --with-machine="machine"
96# set "machine" to override that determined by
97# machine.sh
98#
99# --with-force-machine="machine"
100# force "machine" even if uname(3) provides a value.
101#
102# --with-machine_arch="machine_arch"
103# set "machine_arch" to override that determined by
104# machine.sh
105#
106# --with-default-sys-path="syspath"
107# set an explicit default "syspath" which is where bmake
108# will look for sys.mk and friends.
