| | 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 |
| | 34 | # in the "post-target" section of configure.ac. |
| | 35 | # |
| | 36 | # if [ "${srcdir}" = "." ] ; 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 | # ./ |
| | 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 |

| | 97 | # our caller has already done to figure them out and requiring these two |
