This directory contains command scripts used for building Yale Haskell from the source distribution under Lispworks from Harlequin. We have been using version 3.1.1 on a Sparc. Developers need to source haskell-development instead of haskell-setup in the .cshrc file. Important: Make sure you load the stuff in the patches directory before trying to build the system (the command files do this for you). If you're building on some platform other than a sparc, you'll have to get equivalent patches from Harlequin before proceeding. To rebuild the system: * You need to define environment variables Y2 and LISPWORKS 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/lispworks. * 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 "lispworks" 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 build a new executable. * The new executable is initially called "bin/new-lispworks-haskell". Try it out. If it works, you should rename it to "bin/lispworks-haskell". Make sure that HASKELLPROG (in the haskell-setup script) is correct. * 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 may need to edit these scripts to load the CLX library explicitly if you are using a Lisp executable that doesn't have CLX pre-loaded. When you compile things with the Lispworks compiler, you'll see a bunch of messages complaining about forward references to things that haven't yet been defined. We haven't been able to figure out how to suppress these messages, so unless something else goes wrong you should just ignore them.
