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-dection 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 overriden 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.
