1 | # Configure fragment invoked in the post-target section for subdirs |
2 | # wanting multilib support. | |
3 | # | |
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. | |
9 | # | |
10 | # if [ "${srcdir}" = "." ] ; then | |
11 | # if [ "${with_target_subdir}" != "." ] ; then | |

21 | # Things are complicated because 6 separate cases must be handled: | |
22 | # 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6. | |
23 | # | |
24 | # srcdir=. is special. It must handle make programs that don't handle VPATH. | |
25 | # To implement this, a symlink tree is built for each library and for each | |
26 | # multilib subdir. | |
27 | # | |
28 | # The build tree is layed out as | |
29 | # | |
30 | # ./ | |
6599da04 JM |
31 | # newlib |
32 | # m68020/ | |

37 | # The nice feature about this arrangement is that inter-library references | |
38 | # in the build tree work without having to care where you are. Note that | |
39 | # inter-library references also work in the source tree because symlink trees | |
40 | # are built when srcdir=. | |
41 | # | |
42 | # Unfortunately, trying to access the libraries in the build tree requires | |
43 | # the user to manually choose which library to use as GCC won't be able to | |
44 | # find the right one. This is viewed as the lesser of two evils. | |
45 | # | |
46 | # Configure variables: | |
47 | # ${with_target_subdir} = "." for native, or ${target_alias} for cross. | |
48 | # Set by top level Makefile. | |
49 | # ${with_multisrctop} = how many levels of multilibs there are in the source | |
50 | # tree. It exists to handle the case of configuring in the source tree: | |
51 | # ${srcdir} is not constant. | |
52 | # ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881). | |
53 | # | |
54 | # Makefile variables: | |
55 | # MULTISRCTOP = number of multilib levels in source tree (+1 if cross) | |
56 | # (FIXME: note that this is different than ${with_multisrctop}. Check out.). | |
57 | # MULTIBUILDTOP = number of multilib levels in build tree | |
58 | # MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...) | |
59 | # (only defined in each library's main Makefile). | |
60 | # MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000) | |
61 | # (only defined in each multilib subdir). | |
62 | ||
63 | # FIXME: Multilib is currently disabled by default for everything other than | |
64 | # newlib. It is up to each target to turn on multilib support for the other | |
65 | # libraries as desired. | |
