# Configure fragment invoked in the post-target section for subdirs
# wanting multilib support.
#
# 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.in.
#
# if [ "${srcdir}" = "." ] ; then
#   if [ "${with_target_subdir}" != "." ] ; then
#     . ${with_multisrctop}../../config-ml.in
#   else
#     . ${with_multisrctop}../config-ml.in
#   fi
# else
#   . ${srcdir}/../config-ml.in
# fi
#
# See librx/configure.in in the libg++ distribution for an example of how
# to handle autoconf'd libraries.
#
# 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
#
# ./
#   libg++
#   newlib
#   m68020/
#          libg++
#          newlib
#          m68881/
#                 libg++
#                 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
# newlib.  It is up to each target to turn on multilib support for the other
# libraries as desired.
 
# We have to handle being invoked by both Cygnus configure and Autoconf.
#
# Cygnus configure incoming variables:
# srcdir, subdir, target, arguments
#
# Autoconf incoming variables:
# srcdir, target, ac_configure_args
#
# We *could* figure srcdir and target out, but we'd have to do work that
# our caller has already done to figure them out and requiring these two
# seems reasonable.

2			`# wanting multilib support.`

4			`# It is advisable to support a few --enable/--disable options to let the`
5			`# user select which libraries s/he really wants.`
6			`#`
7			`# Subdirectories wishing to use multilib should put the following lines`
8			`# in the "post-target" section of configure.in.`

20			`# See librx/configure.in in the libg++ distribution for an example of how`
21			`# to handle autoconf'd libraries.`
22			`#`
23			`# Things are complicated because 6 separate cases must be handled:`
24			`# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.`
25			`#`
26			`# srcdir=. is special. It must handle make programs that don't handle VPATH.`
27			`# To implement this, a symlink tree is built for each library and for each`
28			`# multilib subdir.`
29			`#`
30			`# The build tree is layed out as`
31			`#`
32			`# ./`
33			`# libg++`
34			`# newlib`
35			`# m68020/`
36			`# libg++`
37			`# newlib`
38			`# m68881/`
39			`# libg++`
40			`# newlib`
41			`#`
42			`# The nice feature about this arrangement is that inter-library references`
43			`# in the build tree work without having to care where you are. Note that`
44			`# inter-library references also work in the source tree because symlink trees`
45			`# are built when srcdir=.`
46			`#`
47			`# Unfortunately, trying to access the libraries in the build tree requires`
48			`# the user to manually choose which library to use as GCC won't be able to`
49			`# find the right one. This is viewed as the lesser of two evils.`
50			`#`
51			`# Configure variables:`
52			`# ${with_target_subdir} = "." for native, or ${target_alias} for cross.`
53			`# Set by top level Makefile.`
54			`# ${with_multisrctop} = how many levels of multilibs there are in the source`
55			`# tree. It exists to handle the case of configuring in the source tree:`
56			`# ${srcdir} is not constant.`
57			`# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).`
58			`#`
59			`# Makefile variables:`
60			`# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)`
61			`# (FIXME: note that this is different than ${with_multisrctop}. Check out.).`
62			`# MULTIBUILDTOP = number of multilib levels in build tree`
63			`# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)`
64			`# (only defined in each library's main Makefile).`
65			`# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)`
66			`# (only defined in each multilib subdir).`
67
68			`# FIXME: Multilib is currently disabled by default for everything other than`
69			`# newlib. It is up to each target to turn on multilib support for the other`
70			`# libraries as desired.`
