This directory contains command scripts used for building Yale Haskell
from the source distribution under CMU Common Lisp on the sparc.

We have been using version 16f of CMU Common Lisp to build Haskell.
You can ftp this from lisp-rt1.slisp.cs.cmu.edu (128.2.217.9).
There is a known problem with this version of CMU CL: core files built
under SunOS 4.1.2 won't work under 4.1.3, and vice versa.  There are
also apparently compatibility problems with 4.1.3 between sun4c and
sun4m architectures.  Anyway, we have built under 4.1.2 on a sun4c
and 4.1.3 on a sun4m.

Developers need to source haskell-development instead of haskell-setup
in the .cshrc file.

To rebuild the system:

* You need to define environment variables Y2, CMUCL, and CMUCLLIB to 
  point to the appropriate pathnames.  See the haskell-development 
  script for details.

* Make sure that the environment variable PRELUDEBIN (in the 
  haskell-setup script) points to $PRELUDE/cmu.

* Execute the "compile" script.  This will recompile all of the Lisp 
  source files that make up the Yale Haskell system.  Compiled files
  are put in the "cmu" subdirectory of each source directory.

* Execute the "build-prelude" script to compile the standard prelude.  
  Note that this process tends to use up a huge amount of memory!

* Execute the "savesys" script to save a core file.

* The new core file is initially called "bin/new-cmu-haskell.core".
  Use the -core command line argument to cmucl to test it.  If it
  works, you should rename it to "bin/sun4c-haskell.core" (or
  "bin/sun4m-haskell.core") and use the "bin/cmu-haskell" script 
  to execute it.  Make sure HASKELLPROG (in the haskell-setup script) 
  is correct.  Depending on where you have cmucl this script may need 
  editing.

* If you want to build an executable with the X support, you'll also
  need to run the "build-xlib" and "savesys-xlib" scripts.  You
  need to edit these scripts to change the pathname of the file 
  containing the CLX library (or suppress the load entirely if you
  are using a Lisp executable with CLX pre-loaded.).
