30 # It is advisable to support a few --enable/--disable options to let the | |
31 # user select which libraries s/he really wants. | |
32 # | |
33 # Subdirectories wishing to use multilib should put the following lines | |
111 | 34 # in the "post-target" section of configure.ac. |
0 | 35 # |
36 # if [ "${srcdir}" = "." ] ; then | |
37 # if [ "${with_target_subdir}" != "." ] ; then | |
38 # . ${with_multisrctop}../../config-ml.in | |
39 # else | |
40 # . ${with_multisrctop}../config-ml.in | |

46 # | |
47 # Things are complicated because 6 separate cases must be handled: | |
48 # 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6. | |
49 # | |
50 # srcdir=. is special. It must handle make programs that don't handle VPATH. | |
51 # To implement this, a symlink tree is built for each library and for each | |
52 # multilib subdir. | |
53 # | |
54 # The build tree is layed out as | |
55 # | |
56 # ./ | |
57 # newlib | |
58 # m68020/ | |
59 # newlib | |
60 # m68881/ | |
61 # newlib | |
62 # | |
63 # The nice feature about this arrangement is that inter-library references | |
64 # in the build tree work without having to care where you are. Note that | |
65 # inter-library references also work in the source tree because symlink trees | |
66 # are built when srcdir=. | |
67 # | |
68 # Unfortunately, trying to access the libraries in the build tree requires | |
69 # the user to manually choose which library to use as GCC won't be able to | |
70 # find the right one. This is viewed as the lesser of two evils. | |
71 # | |
72 # Configure variables: | |
73 # ${with_target_subdir} = "." for native, or ${target_alias} for cross. | |
74 # Set by top level Makefile. | |
75 # ${with_multisrctop} = how many levels of multilibs there are in the source | |
76 # tree. It exists to handle the case of configuring in the source tree: | |
77 # ${srcdir} is not constant. | |
78 # ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881). | |
79 # | |
80 # Makefile variables: | |
81 # MULTISRCTOP = number of multilib levels in source tree (+1 if cross) | |
82 # (FIXME: note that this is different than ${with_multisrctop}. Check out.). | |
83 # MULTIBUILDTOP = number of multilib levels in build tree | |
84 # MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...) | |
85 # (only defined in each library's main Makefile). | |
86 # MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000) | |
87 # (only defined in each multilib subdir). | |
88 | |
89 # FIXME: Multilib is currently disabled by default for everything other than | |
90 # newlib. It is up to each target to turn on multilib support for the other | |
91 # libraries as desired. | |
92 | |
93 # Autoconf incoming variables: | |
94 # srcdir, host, ac_configure_args | |
95 # | |
96 # We *could* figure srcdir and host out, but we'd have to do work that | |
97 # our caller has already done to figure them out and requiring these two | |
98 # seems reasonable. | |
