Announcing the beta 2 release of Yale Haskell 2.0 The updated version of the Yale Haskell compiler beta release is now available. We have fixed many of the problems in the original beta release and significantly improved performance. We also have ported the system to akcl. The documentation and tutorial have also been improved. Except for a few I/O requests not applicable to our interactive environment, we now implement the full Haskell as defined in the 1.2 report. 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 Lucid common lisp, CMU common lisp, and akcl. 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. 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. Two files are available: haskell-beta-2-source.tar.Z -- full sources haskell-beta-2-sparc.tar.Z -- sparc executable (Note: if anyone wants to contribute a pre-compiled system using the cmu compiler for non-sparc machines please let us know. We are not authorized distribute precompiled akcl versions of our compiler.) You should only need one of these files. The sources take a few hours to build. 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]
