# =========================================================================== # https://www.gnu.org/software/autoconf-archive/ax_enable_builddir.html # =========================================================================== # # SYNOPSIS # # AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])] # # DESCRIPTION # # If the current configure was run within the srcdir then we move all # configure-files into a subdir and let the configure steps continue # there. We provide an option --disable-builddir to suppress the move into # a separate builddir. # # Defaults: # # $1 = $host (overridden with $HOST) # $2 = Makefile.mk # $3 = -all # # This macro must be called before AM_INIT_AUTOMAKE. It creates a default # toplevel srcdir Makefile from the information found in the created # toplevel builddir Makefile. It just copies the variables and # rule-targets, each extended with a default rule-execution that recurses # into the build directory of the current "HOST". You can override the # auto-detection through `config.guess` and build-time of course, as in # # make HOST=i386-mingw-cross # # which can of course set at configure time as well using # # configure --host=i386-mingw-cross # # After the default has been created, additional rules can be appended # that will not just recurse into the subdirectories and only ever exist # in the srcdir toplevel makefile - these parts are read from the $2 = # Makefile.mk file # # The automatic rules are usually scanning the toplevel Makefile for lines # like '#### $host |$builddir' to recognize the place where to recurse # into. Usually, the last one is the only one used. However, almost all # targets have an additional "*-all" rule which makes the script to # recurse into _all_ variants of the current HOST (!!) setting. The "-all" # suffix can be overridden for the macro as well. # # a special rule is only given for things like "dist" that will copy the # tarball from the builddir to the sourcedir (or $(PUB)) for reason of # convenience. # # LICENSE # # Copyright (c) 2009 Guido U.
