   2 # The build process allows for using a cross-compiler.  But the default
   3 # action is to target the same platform that we are running on.  The
   4 # configure script needs to discover the following properties of the

   6 #
   7 #    srcdir
   8 #
   9 #        The is the name of the directory that contains the
  10 #        "configure" shell script.  All source files are
  11 #        located relative to this directory.
  12 #
  13 #    bindir
  14 #
  15 #        The name of the directory where executables should be
  16 #        written by the "install" target of the makefile.
  17 #
  18 #    program_prefix
  19 #
  20 #        Add this prefix to the names of all executables that run
  21 #        on the target machine.  Default: ""
  22 #
  23 #    ENABLE_SHARED
  24 #
  25 #        True if shared libraries should be generated.
  26 #
  27 #    BUILD_CC
  28 #
  29 #        The name of a command that is used to convert C
  30 #        source files into executables that run on the build
  31 #        platform.

  51 #        if that script is available.  This values are used for
  52 #        constructing and installing the TCL extension.
  53 #
  54 #    TARGET_READLINE_LIBS
  55 #
  56 #        This is the library directives passed to the target linker
  57 #        that cause the executable to link against the readline library.
  58 #        This might be a switch like "-lreadline" or pathnames of library
  59 #        file like "../../src/libreadline.a".
  60 #
  61 #    TARGET_READLINE_INC
  62 #
  63 #        This variables define the directory that contain header
  64 #        files for the readline library.  If the compiler is able
