| # It is advisable to support a few --enable/--disable options to let the
 | |
| # user select which libraries s/he really wants.
 | |
| #
 | |
| # Subdirectories wishing to use multilib should put the following lines
 | |
| # in the "post-target" section of configure.ac.
 | |
| #
 | |
| # if [ "${srcdir}" = "." ] ; then

 | |
| #     . ${with_multisrctop}../../config-ml.in

 | |
| # Things are complicated because 6 separate cases must be handled:
 | |
| # 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
 | |
| #
 | |
| # srcdir=. is special.  It must handle make programs that don't handle VPATH.
 | |
| # To implement this, a symlink tree is built for each library and for each
 | |
| # multilib subdir.
 | |
| #
 | |
| # The build tree is layed out as
 | |
| #
 | |
| # ./
 | |
| #   newlib
 | |
| #   m68020/
 | |
| #          newlib
 | |
| #          m68881/
 | |
| #                 newlib
 | |
| #
 | |
| # The nice feature about this arrangement is that inter-library references
 | |
| # in the build tree work without having to care where you are.  Note that
 | |
| # inter-library references also work in the source tree because symlink trees
 | |
| # are built when srcdir=.
 | |
| #
 | |
| # Unfortunately, trying to access the libraries in the build tree requires
 | |
| # the user to manually choose which library to use as GCC won't be able to
 | |
| # find the right one.  This is viewed as the lesser of two evils.
 | |
| #
 | |
| # Configure variables:
 | |
| # ${with_target_subdir} = "." for native, or ${target_alias} for cross.
 | |
| # Set by top level Makefile.
 | |
| # ${with_multisrctop} = how many levels of multilibs there are in the source
 | |
| # tree.  It exists to handle the case of configuring in the source tree:
 | |
| # ${srcdir} is not constant.
 | |
| # ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
 | |
| #
 | |
| # Makefile variables:
 | |
| # MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
 | |
| # (FIXME: note that this is different than ${with_multisrctop}.  Check out.).
 | |
| # MULTIBUILDTOP = number of multilib levels in build tree
 | |
| # MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
 | |
| # (only defined in each library's main Makefile).
 | |
| # MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
 | |
| # (only defined in each multilib subdir).
 | |
| 
 | |
| # FIXME: Multilib is currently disabled by default for everything other than

 | |
| # libraries as desired.
