We provide an option --disable-builddir to suppress the move into 14# a separate builddir. 15# 16# Defaults: 17# 18# $1 = $host (overridden with $HOST) 19# $2 = Makefile.mk 20# $3 = -all 21# 22# This macro must be called before AM_INIT_AUTOMAKE. It creates a default 23# toplevel srcdir Makefile from the information found in the created 24# toplevel builddir Makefile. It just copies the variables and 25# rule-targets, each extended with a default rule-execution that recurses 26# into the build directory of the current "HOST". You can override the 27# auto-detection through `config.guess` and build-time of course, as in 28# 29# make HOST=i386-mingw-cross 30# 31# which can of course set at configure time as well using 32# 33# configure --host=i386-mingw-cross 34# 35# After the default has been created, additional rules can be appended 36# that will not just recurse into the subdirectories and only ever exist 37# in the srcdir toplevel makefile - these parts are read from the $2 = 38# Makefile.mk file 39# 40# The automatic rules are usually scanning the toplevel Makefile for lines 41# like '#### $host |$builddir' to recognize the place where to recurse 42# into. Usually, the last one is the only one used. However, almost all 43# targets have an additional "*-all" rule which makes the script to 44# recurse into _all_ variants of the current HOST (!!) setting. The "-all" 45# suffix can be overridden for the macro as well. 46# 47# a special rule is only given for things like "dist" that will copy the 48# tarball from the builddir to the sourcedir (or $(PUB)) for reason of 49# convenience. 50# 51# LICENSE 52# 53# Copyright (c) 2009 Guido U.
