   1 # Configure fragment invoked in the common section for subdirs
   2 # wanting multilib support.
   3 #
   4 # The common section was chosen because xiberty clobbers $srcdir in the
   5 # common section of its configure.in.
   6 #
   7 # The intent is to keep as much of this in one place as possible (and out
   8 # of each subdirectory, eg: newlib, libio, etc.) until the right way to do
   9 # this (ha ha) is decided upon.
  10 #
  11 # This is where a target selects what multilib directories to build.
  12 # It is advisable to support a few --enable/--disable options to let the
  13 # user select which libraries s/he really wants.
  14 #
  15 # Subdirectories wishing to use multilib should put the following lines
  16 # in the initial ("common") section of configure.in:
  17 #
  18 #if [ -n "${with_multilib_top}" ]; then
  19 #       . ${with_multilib_top}/../cfg-ml-com.in
  20 #else
  21 #       . ${srcdir}/../cfg-ml-com.in
  22 #fi
  23 #
  24 # `with_multilib_top' exists to handle the case of configuring in the source
  25 # tree: ${srcdir} is not constant.
  26 #
  27 # The following should be added to the "post-target" section of configure.in:
  28 #
  29 #if [ -n "${with_multilib_top}" ]; then
  30 #       . ${with_multilib_top}/../cfg-ml-pos.in
  31 #else
  32 #       . ${srcdir}/../cfg-ml-pos.in
  33 #fi
  34
  35 # FIXME: Multilib is currently disabled by default for everything other than
  36 # newlib.  It is up to each target to turn on multilib support for the other
  37 # libraries as desired.
  38 #
  39 # FIXME: It would be better if we could use the --print-multi-lib switch to
  40 # gcc to get the list of directories to build, but at this point the compiler
  41 # has not been built.
  42
  43 # Only do this if --enable-multilib.
  44 # And only if at the top level, not a multilib subdirectory.
  45
  46 if [ "${enable_multilib}" = yes -a -z "${with_multisubdir}" ]; then
  47
  48 # Doing this in the common section means ${target} isn't set yet, so compute
  49 # a copy here.  This is a bit kludgey, but again the current (short term) goal
  50 # is to be as unobtrusive (sp?) to the rest of the sources as possible.
