1: 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. 109# 110# AUTHOR: 111# Simon J.
