Contents of README:Description of GCL (GNU Common Lisp) system. OVERVIEW: The GCL system contains C and Lisp source files to build a Common Lisp sytem. The original KCL system was written by Taiichi Yuasa and Masami Hagiya in 1984. The AKCL system work was begun in 1987 by William Schelter and continued through 1994. A number of people have contributed ports and pieces. The file doc/contributors lists some of these. In 1994 AKCL was released as GCL (GNU Common Lisp) under the GNU public library license. Version akcl-1-624 was the last version made under the old license and using the old file change mechanism. This readme only applies to versions gcl.1.0 and later. The GNU library license does allow redistribution of executables containing GCL as well as proprietary code, but such redistribution must be accompanied by sufficient material (eg .o files) to allow recipients to rebuild an executable, after possibly modifying GCL. See the GNU file COPYING.LIB-2.0 for a full description of your right to copy this software. Releases of GCL after 2.0 contain a GCL connection with the windowing tools TCL/TK. If 'configure' is able to find the relevant libraries on your system, then a gcl-tk server will be compiled as well by the main make. It is based on TK 8.0 and TCL 8.0 and available from ftp.cs.berkeley.edu and many mirrors. OBTAINING SOURCES: ----------------- * There are source files on ftp.ma.utexas.edu:pub/gcl/gcl.x.x.tgz You probably want the highest XX version number. For example gcl-1.0.tgz would allow you to build the version 1.0 of GCL. In the following this compressed tar file is simply referred to as gcl.tgz. If you do not have gzip it is available in the directory /anyonymous@prep.ai.mit.edu:/u2/emacs . Hopefully sometime, GCL will also be available on prep.ai.mit.edu. MAKING THE SYSTEM: ================== To make the whole system, if you have obtained gcl.tgz. UNCOMPRESS and UNTAR the SOURCES: -------------------------------- Change to a directory in which you wish to put gcl, eg /usr/local, which we shall call PREFIX-DIR. Copy the file gcl.tgz to the PREFIX-DIR. % gzip -dc gcl.tgz | tar xvf - This will create the directory ${PREFIX-DIR}/gcl-1.xxx with all the sources in it ADD MACHINE DEFINITIONS TO MAKEFILES: ------------------------------------ Determine the NAME of your machine by looking in the MACHINES file (e.g. sun3-os4). % cd gcl-2.xxx % ./configure You should finally be ready to go! Note that if you have tcl/tk (version 4.2 tk or 7.6 tcl or later), then a file tclConfig.sh and tkConfig.sh should exist in some place such as /usr/local/lib. RUNNING MAKE: ------------ % make The make should continue without error. There may be occasional warnings from the C compiler, but all files should compile successfully producing .o files. At the end you should see a message at the end "Make of GCL xxx completed", where xxx stands for the version number. TRY IT OUT: ---------- When it has finally finished you may invoke GCL by using % xbin/gcl GCL (GNU Common Lisp) Version(1.0) Apr 21 00:52:31 CDT 1994 Contains Enhancements by W. Schelter >(+ 2 3) >5 If you had TCL/TK, then you should be able to do >(si::tkconnect) >(load "gcl-tk/demos/widget.lisp") Note there are currently problems with the demos, since they were based on an older version of tcl/tk. (setq si::*tk-library* "/usr/lib/tk") [where /usr/lib/tk/tk.tcl is] INSTALLING: ---------- To install under /usr/local do make install To specify an alternative directory such as /lusr do make install PREFIX_DIR=/lusr The default installation puts a full executable in /usr/local/lib/gcl-version/unixport/saved_gcl and some documentation in /usr/local/lib/gcl-x.x/info/ and some autoloading files in /usr/local/lib/gcl-x.x/lsp and a shell script in /usr/local/lib/gcl-x.x/xbin/gcl This script is also copied to /usr/local/bin On a successful make, the xbin/notify script sends a note to maintainers, so that they can know which newer software platforms, need attention and which do not. To disable this you may remove this file and replace it with a dummy one (see makefile). FUTURE DIRECTIONS ================= (and how you may be able to help) Volunteers should contact William Schelter (wfs@math.utexas.edu) a) Upgrading to comply with the forthcoming ANSI standard. Work needs to be done. b) Need work on providing a high level window interface. One possible way would be a good connection with TCL/TK. Another would be to go in the direction of CLIM. A new compiler has been written, which is closer to the ANSI standard and provides some other benefits. It will be in a future release. We will need people willing to beta test and isolate any bugs. Additonal work planned or desired: * Clean up distribution and installation. Make it easier to link in C code such as Novak's window stuff. Faslink is not portable (since many systems don't support ld -A). * Introduce COMMON-LISP and COMMON-LISP-USER packages as per ANSI standard, change the package functions to behave as in the ANSI standard. Any other changes which people can identify which would make life easier, and are compatible with ANSI. * Introduce C level and Lisp level way of signalling errors of the types specified by the ANSI standard. Make it so that when the CLOS is present these become error objects. * Fix the run-process stuff to properly deallocate processes and have listen do the right thing, by using select, which is POSIX. Try to make it compatible with the one in Allegro or Lucid. Done * Turn ANSI documentation into the new Lisp's on-line documentation. This will be useful for development and for users. No sense in basing our work on the CLTL 2. Must go to the ANSI document itself. * Make an appropriate Unix man page. * Add my allocation files and other changes necessary to make INTERRUPTS safe. This probably means adding in all the C files which I have already written. * Change function calls to all refer to C stack and pass return values in a uniform way, the way the new compiler does it. This will greatly improve funcalling, since right now there are generally two types of functions which can be expected, and they expect their arguments in different places. * Change to the new compiler which does things better from the ANSI point of view, and is smaller, and makes all function calls go via the C stack. * Include CLOS support. Possibly take this from PCL or from Attardi, who has written some. Done * Include a windowing interface with TCL/TK which is capable of producing TK (similar to Motif but public) style windows and scrollable menus, etc. This implementation must be done in such a way that it works in at least one additional Lisp, such as Allegro or Lucid. * Loop package: either make sloop satisfy the standard or include another implementation. * Changes to READ for ANSI, (including case sensitivity, etc.). * Byte compiler based on first pass of the new compiler. Ideally provides very small code and extremely rapid compiling for general platform. Notes: I have put the interrupt and run-process stuff early on since it is necessary for window development. * Construct a Common Lisp test suite to help debug new releases. DOCUMENTATION: ============== If you use GNU emacs, a convenient method for viewing documentation of Common Lisp functions (or functions in an extended system), is provided by the doc/find-doc.el file. This will be installed when you do make in the doc directory. Adding the following to your .emacs file will allow you to use C-h d to find documentation. (autoload 'find-doc "find-doc" nil t) (global-set-key "d" 'find-doc) (visit-doc-file "/usr/local/lib/gcl/doc/DOC") See the file find-doc.el for more information. Otherwise you may use the describe command inside Lisp. For example (describe 'print) will print out information about print. It will access the gcl-si.info, gcl-tk.info, and gcl.info if these exist. gcl.info (containing the ansi proposed definitions) is on ftp.ma.utexas.edu:pub/gcl/gcl.info.tgz TROUBLE SHOOTING (some common problems reported): ---------------- 1) Did you extract the files with the original write dates--make depends heavily on this? 2) Did you use -O on a compiler which puts out bad code? Any time you change the settings or use a new c compiler this is a tricky point. 3) If you can't save an image, try doing so on the file server rather than a client. 4) Doing the make on a client with the main files on a server, has sometimes caused random breakage. The large temp files used by the C compiler seem to sometimes get transferred incorrectly. Solution: use the server for the compile. 5) Did you make changes in the .defs or .h files, other than just commenting out a CC=gcc line? 6) Did you read the recommendations in the XXXX.defs file on what C compiler versions work? 7) (si::tkconnect) fails: a) Make sure DISPLAY variable set before starting gcl. b) gcltkaux (subsidiary process) uses shared libraries and you would need LD_LIBRARY_PATH set on say suns, to say where those are if they are not in default places. [make sure "wish" would work] CHANGING THINGS: MAYBE EDIT THREE FILES: -------------------- Normally you should not need to edit ANY files. There may be some parameter sizes you wish to change or if you don't have gcc where we have made that the default, then see CC below. EDIT the ./add-defs script If when you do `add-defs machine` the add-defs script is not able to find directories where things like tk.h, libX11.a etc are, then it will print out a message. You can to have it look in some extra places on your machine, or in a different order. Note that if it fails to find these things the tcl/tk support will not be built, but you will have an ordinary common lisp. EDIT the appropriate h/NAME.defs file. These are definitions to be included in the various makefiles. For example if the `NAME' of your machine is sun3-os4. % emacs h/sun3-os4.defs * CC: set C compiler options. For example, if you are using the GNU C compiler: CC = gcc -msoft-float -DVOL=volatile -I$(GCLDIR)/o Or, if you are using the conventional UNIX C compiler: CC = cc -DVOL= -I. -I$(GCLDIR)/o * ODIR_DEBUG: ODIR_DEBUG= -g If you want files in the main c source compiled with debugging information. Note this is incompatible with OFLAGS= -O on some compilers. Size will be smaller without -g, but you are then helpless in the face of problems. * INITFORM: The normal thing is to just have the one form required for fast loading. INITFORM=(si::build-symbol-table) ----------- EDIT the file h/NAME.h (eg h/sun3-os4.h) (Actually you probably don't need to change it) This file will be included by virtually every compilation of C files, except the translated C produced by kcl. % emacs h/sun3-os4.h if you wish to change a parameter such as MAXPAGE 16384 established in bsd.h (ie. number of 2000 byte pages you want as your absolute max swap space). MAXPAGE must be a power of 2. #undef MAXPAGE #define MAXPAGE (2 * 16384) You may similarly redefine VSSIZE the maximum size for the value stack (running very deep recursion interpreted may well require this).
