Up to [gforth] / gforth

add kernel.TAGS dependency and target in the Makefile

    1: You need gcc version 2.0 or later to compile gforth.
    2: 
    3: First, type
    4: 
    5: ./configure
    6: 
    7: (see Section Configuration Options below for details).
    8: 
    9: After configuration, type
   10: 
   11: make
   12: 
   13: Now you can check whether your shiny new Forth system works. Say
   14: 
   15: make check
   16: 
   17: You can run some benchmarks with
   18: 
   19: make bench
   20: 
   21: and compare them with the results in Benchres and in the manual.
   22: 
   23: If everything is all right, you may want to install gforth. Type
   24: 
   25: make install
   26: 
   27: You have to make an entry in the info directory file manually (see
   28: Installing Info Files, below).
   29: 
   30: For paper documentation, print gforth.ps (a Postscript file (300dpi
   31: fonts, i.e., it works, but does not produce best quality on better
   32: printers)), or say
   33: 
   34: make gforth.dvi
   35: 
   36: and print the resulting file gforth.dvi. You can also get the
   37: documentation in HTML format by typing
   38: 
   39: make html
   40: 
   41: If you prefer plain ASCII documentation, you can 
   42: 
   43: make doc/gforth.txt
   44: 
   45: or just concatenate the files gforth.info-* ('cat gforth.info-*' under
   46: Unix); the result of the latter option is a little worse.
   47: 
   48: You can find binary distributions, documentation in HTML and plain
   49: text format and information on known installation problems at
   50: http://www.complang.tuwien.ac.at/forth/gforth/.
   51: 
   52: 
   53: 		Configuration Options
   54: 
   55: If you use GNU make, you can build in a directory different from the
   56: source directory by changing to the build directory and invoking
   57: configure thus:
   58: 
   59: $srcdir/configure
   60: 
   61: where $srcdir is the source directory. (Note that we tested this only
   62: for installation; i.e., if you want to hack the Gforth sources, you
   63: should probably build in the source directory).
   64: 
   65: configure has the following useful parameters:
   66:   --prefix=PREFIX         install architecture-independent files in PREFIX
   67:                           [default: /usr/local]
   68:   --exec-prefix=PREFIX    install architecture-dependent files in PREFIX
   69:                           [default: same as prefix]
   70:   --enable-force-reg      Use explicit register declarations if they appear in
   71:                           the machine.h file. This can cause a good speedup,
   72:                           but also incorrect code with some gcc versions on
   73:                           some processors (default disabled).
   74:   --enable-direct-threaded      Force direct threading. This may not work on
   75:                                 some machines and may cause slowdown on others.
   76:                                 (default processor-dependent)
   77:   --enable-indirect-threaded    Force indirect threading. This can cause a
   78:                                 slowdown on some machines.
   79:                                 (default processor-dependent)
   80:   --with-debug     specifies option -g to compile with debug info (default)
   81:   --without-debug  omits the -g switch and creates smaller images on
   82:                    machines where strip has problems with gcc style
   83:                    debugging informations.
   84:   --help: tells you about other parameters.
   85: 
   86: The file Benchres shows which combination of the -enable options we
   87: tried gave the best results for various machines.
   88: 
   89: If you don't like the defaults for the installation directories, you
   90: should override them already during configure.  E.g., if you want to
   91: install in the /gnu hierarchy instead of in the default /usr/local
   92: hierarchy, say
   93: 
   94: ./configure --prefix=/gnu
   95: 
   96: Moreover, if your GCC is not called gcc (but, e.g., gcc-2.7.1), you
   97: should say so during configuration. E.g.:
   98: 
   99: env CC=gcc-2.7.1 ./configure
  100: 
  101: You can also pass additional options to gcc in this way, e.g., if you
  102: want to generate an a.out executable under Linux with gcc-2.7.0:
  103: 
  104: env "CC=gcc -b i486-linuxaout -V 2.7.0" ./configure
  105: 
  106: You can change the sizes of the various areas used in the default
  107: image `gforth.fi' by passing the appropriate Gforth command line
  108: options in the FORTHSIZES environment variable:
  109: 
  110: env "FORTHSIZES=--dictionary-size=256k --data-stack-size=16k --fp-stack-size=15872b --return-stack-size=15k --locals-stack-size=14848b" ./configure
  111: 
  112: The line above reaffirms the default sizes. Note that the locals
  113: stack area is also used as input buffer stack.
  114: 
  115: If C's "long long" do not work properly on your machine (i.e., if the
  116: tests involving double-cell numbers fail), you can build Gforth such
  117: that it does not use "long long":
  118: 
  119: env ac_cv_sizeof_long_long=0 ./configure
  120: 
  121: 
  122: 			Cross-Configuration
  123: 
  124: A few tests made by the configure script do not work in a
  125: cross-compilation situation. You have to provide the results of these
  126: tests by hand. E.g., if you compile for a 386 architecture processor:
  127: 
  128: env ac_cv_sizeof_char_p=4 ac_cv_sizeof_short=2 ac_cv_sizeof_int=4 ac_cv_sizeof_long=4 ac_cv_sizeof_long_long=8 ac_cv_c_bigendian=no ./configure
  129: 
  130: The ac_cv_sizeof_... variables give the sizes of various C types;
  131: ac_cv_sizeof_char_p is the same as "sizeof(char*)" in C code. The
  132: ac_cv_c_bigendian variable gives the byte order.
  133: 
  134: 
  135: 		Preloading installation-specific code
  136: 
  137: If you want to have some installation-specific files loaded when
  138: Gforth starts (e.g., an assembler for your processor), put commands
  139: for loading them into /usr/local/share/gforth/site-forth/siteinit.fs
  140: (if the commands work for all architectures) or
  141: /usr/local/lib/gforth/site-forth/siteinit.fs (for
  142: architecture-specific commands);
  143: /usr/local/lib/gforth/site-forth/siteinit.fs takes precedence if both
  144: files are present (unless you change the search path). The file names
  145: given above are the defaults; if you have changed the prefix, you have
  146: to replace "/usr/local" in these names with your prefix.
  147: 
  148: By default, the installation procedure creates an empty
  149: /usr/local/share/gforth/site-forth/siteinit.fs if there is no such
  150: file.
  151: 
  152: If you change the siteinit.fs file, you should run "make install"
  153: again for the changes to take effect (Actually, the part of "make
  154: install" starting with "rm gforth.fi" is sufficient).
  155: 
  156: 
  157: 		Multiple Versions and Deinstallation
  158: 
  159: Several versions of Gforth can be installed and used at the same
  160: time. Version `foo' can be invoked with `gforth-foo'. We recommend to
  161: keep the old version for some time after a new one has been installed.
  162: 
  163: You can deinstall this version of Gforth with 'make uninstall' and
  164: version foo with 'make uninstall VERSION=foo'. 'make uninstall' also
  165: tells you how to uninstall Gforth completely.
  166: 
  167: 
  168: 		Installing Info Files
  169: 
  170: Info is the GNU project on-line documentation format. You can read
  171: info files either from within Emacs (Ctrl-h i) or using the
  172: stand-alone Info reader, 'info'.
  173: 
  174: If you use the default install root of '/usr/local' then the info
  175: files will be installed in '/usr/local/info'.
  176: 
  177: Many GNU/Linux distributions are set up to put all of their
  178: documentation in '/usr/info', in which case you might have to do a
  179: couple of things to get your environment set up to accommodate files
  180: in both areas:
  181: 
  182: 1. Add an INFOPATH environment variable. The easiest place to do
  183: this is '/etc/profile', right next to PATH and MANPATH:
  184: 
  185: INFOPATH=/usr/local/info:/usr/info
  186: 
  187: 2. Create a file called 'dir' in 'usr/local/info'. Use the file
  188: '/usr/info/dir' as a template. You can add the line for gforth
  189: manually, or use '/sbin/install-info' (man install-info for details).
