 Funktion : Installation notes for CLiCC

 $Revision: 1.6 $

 This  file describes  the  system requirements  and  the installation
 procedure for the CLiCC Common Lisp to C compiler.
 
 See the files README and COPYRIGHT for further information.  See also 
 the files src/compiler/README and lib/README to get information about 
 how to use CLiCC.  After installation you should apply  CLiCC  to our 
 test suite in src/test. Look at src/test/README for details.
 
 ---------------------------------------------------------------------
 
 0. Requirements
    ~~~~~~~~~~~~
 First of all note that you need a  Common Lisp  system to boot CLiCC.
 You also need a C compiler available on your target system,  i.e. the
 machine on which you want to run the executables.  This machine might
 be but of course needs not to be the same as your development system,
 i.e. the machine on which you want to run CLiCC.
 
 At present  we  recommend to use  CLiCC  within a Common Lisp system, 
 although  you might compile CLiCC to C as well, and then use it as an 
 application  program  with command line arguments.  It is a known bug 
 that this procedure will not work with Release 0.6.1. We refer to one 
 of the next releases for further information and a fix.
 
 The following is a list of Common Lisp systems we tested to be usable
 for CLiCC to run: 
 
   - Allegro Common Lisp 4.1 (Franz Inc.)
   - Sun (Lucid) Common Lisp 4.0 (Sun Microsystems Inc., Lucid Inc.)
   - CMU Common Lisp 16f (Carnegie Mellon University)
   - CLISP (Bruno Haible & Michael Stoll)
 
 You need an ANSI-C  or K&R-C compiler to generate  the CLiCC runtime-
 system library and executables. On PC compatible machines you have to 
 use a 32-bit C compiler, preferably the GNU-C port of DJ Delorie.
 
 If you want to use  the makefiles contained in our distribution,  you 
 will  need the  GNU Make Utility  "gmake".  GNU  Make is available on 
 ftp.informatik.uni-kiel.de (134.245.15.113) as:
 
   /pub/systems/gnu/make-3.68.tar.gz
 
 ---------------------------------------------------------------------
 
 1. Installation
    ~~~~~~~~~~~~
 You may leave out steps f) and g), if you want to use the precompiled
 lisp files of the runtime system. They are part of this distribution,
 and you will save a lot of time.
 
 a) Decide where to  locate the CLiCC root directory, further referred 
    to as $CLICCROOT.  You need approx.  9 MByte  of free  disk  space 
    available.
 
 b) Set the environment variable CLICCROOT to point to this directory.
 
 c) Locate your Common Lisp system, further referred to as "lisp".
 
 d) Locate your C compiler,  further referred to as "yourcc". Edit the
    files
 
      $CLICCROOT/bin/rt   and    $CLICCROOT/bin/cl .
 
    and change the parameters "CC=acc" into "CC=yourcc".
 
 e) If you want to use a K&R-C compiler, edit the file
 
      $CLICCROOT/src/compiler/config.lisp 
   
    and change the line
 
        (defvar *ANSI-C* T)
 
    into
 
        (defvar *ANSI-C* NIL)
 
 f) Change to the directory $CLICCROOT/src/compiler.
 
 g) Start Common Lisp. Load the file "clcload.lisp". 
    Run (compile-clicc) first and then (ask-runtime). 
    Answer "A" and take a cup of tea.
 
         ------------------------------------------------------------
         At this point you can  decide to generate separate files for 
         each runtime system function, which will take quite a lot of
         installation  time,  but helps to generate much smaller exe-
         cutables.  If you want  to  split the runtimesystem,  toggle 
         "S)plit" to be "on" before answering "A".
         ------------------------------------------------------------
 
 h) Run  $CLICCROOT/bin/rt  to generate the  CLiCC runtime  libraries
    $CLICCROOT/lib/rtc.a  and  $CLICCROOT/lib/rtl.a.  Those libraries
    will be linked with application programs compiled by CLiCC.

 2. Example Dialogue
    ~~~~~~~~~~~~~~~~
 The following  shows an example  dialogue to install CLiCC,  using a
 shell prompting with "% ", and a  Common Lisp system  prompting with
 "cl>":
 
   -------------------------------------------------------------------
   % mkdir ~/CLiCC
   % cd ~/CLiCC
   % setenv CLICCROOT /home/karlo/wg/CLiCC
   % cd src/compiler
   % lisp

   ...

   cl> (load "clcload.lisp")
   ; Loading ...

   ...

   cl> (compile-clicc)
   ;;; CLiCC, the Common Lisp to C Compiler --- Version 0.6.1
   ;;; Copyright (C) 1993 Christian-Albrechts-Universitaet zu Kiel
   
   ...

   cl> (ask-runtime)
   A)ll L)isp-module I)nline-module 
   P)rint messages is on  S)plit is off  O)nly Pass1 is off  K)ill C-Files

   ;;; Initialize Special Forms
   ;;; Initialize System Macros
   ;;; Initialize System Functions
   ;;; Initialize Evaluator
   ;;; Syntactic and semantic analysis
   ;;; File "inline.lisp"

   ...

   cl> (exit)
  
   % $CLICCROOT/bin/rt
   acc -I/home/karlo/wg/CLiCC/lib -O -c values.c unix.c
