Announcing the beta release of Yale Haskell 2.0 The newest version of the Yale Haskell compiler is now available. This is the `beta' version of our system. A few minor Haskell features are not yet implemented and a number of performance issues have not yet been addressed. However, we hope that this is a very solid and user-friendly system. We are releasing two versions of the system: an executable compiled with the CMU Common Lisp system which runs on Sparc systems and a full source release which will build on both Lucid common lisp and the CMU system. The build process consumes a large amount of virtual memory - you may have some difficulty using the source release. If you cannot use either of these versions, please wait for the next release. It is possible to port the system to other Lisps but this should only be attempted by experienced lisp hackers. We will try to release an akcl version in another few weeks. We expect to have the `real' release of Yale Haskell ready in another month or two. This will correct any bugs in the beta release, fill in all missing Haskell features, be much more portable, have improved documentation, and much better performance. Our system is available for anonymous ftp at all three Haskell ftp sites: Site Host name Raw IP address Chalmers animal.cs.chalmers.se 129.16.225.66 Glasgow ftp.dcs.glasgow.ac.uk 130.209.240.50 Yale nebula.cs.yale.edu 128.36.13.1 The files are in the directory pub/haskell/yale. (They may be in pub/haskell/library/incoming instead) Two files are available: haskell-beta-1-source.tar.Z -- full sources haskell-beta-1-sparc.tar.Z -- sparc executable You should only need one of these files. The sources take a hour or two to build on lucid and about twice than on cmu. The executable is ready to run immediately. To obtain Yale Haskell via ftp: - Move to the directory where you intend to place Yale Haskell - Ftp to one of the sites and login anonymously - Get the tar file: get xxx.tar.Z where xxx is the distribution you want - cd to pub/haskell/yale - Uncompress and untar the file on your machine: uncompress haskell-*.tar.Z tar xf haskell-*.tar - Consult the documentation for further instructions. Either print out the reference manual in doc/manual/haskell.dvi or look at install.verb in the same directory. Send any comments or questions to [EMAIL PROTECTED]
