28e9041c | 30 | # It is advisable to support a few --enable/--disable options to let the |

33 | # Subdirectories wishing to use multilib should put the following lines | |
34 | # in the "post-target" section of configure.in. | |
35 | # | |
36 | # if [ "${srcdir}" = "." ] ; then | |
37 | # if [ "${with_target_subdir}" != "." ] ; then | |

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 | # ./ | |
28e9041c | 57 | # newlib |
58 | # m68020/ | |
28e9041c | 59 | # newlib |
60 | # m68881/ | |
28e9041c | 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). | |
