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

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