| 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 |
| 12 | # . ${with_multisrctop}../../config-ml.in |
| 13 | # else |
| 14 | # . ${with_multisrctop}../config-ml.in |

| 20 | # See librx/configure.in in the libg++ distribution for an example of how |
| 21 | # to handle autoconf'd libraries. |
| 22 | # |
| 23 | # Things are complicated because 6 separate cases must be handled: |
| 24 | # 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6. |
| 25 | # |
| 26 | # srcdir=. is special. It must handle make programs that don't handle VPATH. |
| 27 | # To implement this, a symlink tree is built for each library and for each |
| 28 | # multilib subdir. |
| 29 | # |
| 30 | # The build tree is layed out as |
| 31 | # |
| 32 | # ./ |
| 33 | # libg++ |
| 34 | # newlib |
| 35 | # m68020/ |
| 36 | # libg++ |
| 37 | # newlib |
| 38 | # m68881/ |
| 39 | # libg++ |
| 40 | # newlib |
| 41 | # |
| 42 | # The nice feature about this arrangement is that inter-library references |
| 43 | # in the build tree work without having to care where you are. Note that |
| 44 | # inter-library references also work in the source tree because symlink trees |
| 45 | # are built when srcdir=. |
| 46 | # |
| 47 | # Unfortunately, trying to access the libraries in the build tree requires |
| 48 | # the user to manually choose which library to use as GCC won't be able to |
| 49 | # find the right one. This is viewed as the lesser of two evils. |
| 50 | # |
| 51 | # Configure variables: |
| 52 | # ${with_target_subdir} = "." for native, or ${target_alias} for cross. |
| 53 | # Set by top level Makefile. |
| 54 | # ${with_multisrctop} = how many levels of multilibs there are in the source |
| 55 | # tree. It exists to handle the case of configuring in the source tree: |
| 56 | # ${srcdir} is not constant. |
| 57 | # ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881). |
| 58 | # |
| 59 | # Makefile variables: |
| 60 | # MULTISRCTOP = number of multilib levels in source tree (+1 if cross) |
| 61 | # (FIXME: note that this is different than ${with_multisrctop}. Check out.). |
| 62 | # MULTIBUILDTOP = number of multilib levels in build tree |
| 63 | # MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...) |
| 64 | # (only defined in each library's main Makefile). |
| 65 | # MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000) |
| 66 | # (only defined in each multilib subdir). |
| 67 | |
| 68 | # FIXME: Multilib is currently disabled by default for everything other than |
| 69 | # newlib. It is up to each target to turn on multilib support for the other |
| 70 | # libraries as desired. |
| 71 | |
| 72 | # We have to handle being invoked by both Cygnus configure and Autoconf. |
| 73 | # |

| 76 | # |
