    1: #
    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 
    5: # build and target systems:
    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.
   32: #
   33: #    BUILD_CFLAGS
   34: #
   35: #        Switches that the build compiler needs in order to construct
   36: #        command-line programs.
   37: #
   38: #    BUILD_LIBS
   39: #
   40: #        Libraries that the build compiler needs in order to construct
   41: #        command-line programs.
   42: #
   43: #    BUILD_EXEEXT
   44: #
   45: #        The filename extension for executables on the build
   46: #        platform.  "" for Unix and ".exe" for Windows.
   47: #
   48: #    TCL_*
   49: #
   50: #        Lots of values are read in from the tclConfig.sh script,
   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 
   65: #        to find <readline.h> on its own, then this can be blank.
   66: #
   67: #    TARGET_EXEEXT
   68: #
   69: #        The filename extension for executables on the
   70: #        target platform.  "" for Unix and ".exe" for windows.
   71: #
   72: # The generated configure script will make an attempt to guess
   73: # at all of the above parameters.  You can override any of
   74: # the guesses by setting the environment variable named
   75: # "config_AAAA" where "AAAA" is the name of the parameter
   76: # described above.  (Exception: srcdir cannot be set this way.)
   77: # If you have a file that sets one or more of these environment
   78: # variables, you can invoke configure as follows:
   79: #
   80: #           configure --with-hints=FILE
   81: #
   82: # where FILE is the name of the file that sets the environment
   83: # variables.  FILE should be an absolute pathname.
   84: #
   85: # This configure.in file is easy to reuse on other projects.  Just
   86: # change the argument to AC_INIT().  And disable any features that
   87: # you don't need (for example BLT) by erasing or commenting out
   88: # the corresponding code.
