# 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, host, arguments |
|||
# |
|||
# Autoconf incoming variables: |
|||
# srcdir, host, ac_configure_args |
|||
# |
|||
# We *could* figure srcdir and host out, but we'd have to do work that |
|||
# our caller has already done to figure them out and requiring these two |
|||
# seems reasonable. |
|||
# Note that `host' in this case is GCC's `target'. Target libraries are |
|||
# configured for a particular host. |
