Are there any free software or public domain occam compilers?
[This has come up a few times before. Nobody's ever reported anything other
than the Inmos compilers. -John]

I found the following while looking for a logo interpreter for suns: This is just a lex and yacc front end (since we had such a wonderful discussion about whether it was possible to do this or not a while back!) written by > Peter Polkinghorne ( pjmp@uk.co.gec-rl-hrc or ...!mcvax!ukc!hrc63!pjmp ) > GEC Hirst Research Centre, East Lane, Wembley, Middlesex, UK who is not intending to maintain the grammar, it is just offered as an example of using lex and yacc on occam. But he hopes someone out there will produce a back-end someday soon! I found it on the following machine wuarchive.wustl.edu (128.252.135.4) under mirrors/unix-c/languages I just tried to check the connection though, and it said that the disk that holds the archive had just died. -- Debora Weber-Wulff snail: FU Berlin, ZI Fachdidaktiken, Habelschwerdter Allee 45, W-1000 Berlin 33 email: weberwu@inf.fu-berlin.de, dww@math.fu-berlin.de [Despite a note when you connect that the disk for /mirrors has died, the file /mirrors/unix-c/languages.occam/occam.tar-z is in fact there and contains two yacc occam parsers. -John] -- Send compilers articles to compilers@iecc.cambridge.ma.us or {ima | spdcc | world}!iecc!compilers.

This may not quite be what the original poster asked for (I lost the original posting), but a search via archie lists the following sites with a full OCCAM system. From the README: > OCCAM system for UNIX 4.2bsd > ---------------------------- > >Description: >------------ > >This directory contains a beta site version of an OCCAM system. >It includes a compiler for standard Occam with a few extensions (specified >in the user manual). The compiler produces Vax/Tahoe assembler code. >Also included is a library of runtime routines acting as the parallel >machine simulator. Strong tracing options on the simulator's activities >are provided. Two things to note though: 1) This package is rather old. 2) I remember picking this package up a couple of years ago, and it churns out (to my knowledge) ONLY Vax/Tahoe assembler code (as stated above). If you're willing to try porting it to another architecture, more power to you. 8-) The sites are: Host cs.utah.edu (128.110.4.21) Last updated 12:04 26 Mar 1991 Location: /pub FILE rw-r--r-- 101131 Nov 9 10:18 occam.tar.Z Host apple.com (130.43.2.2) Last updated 05:05 22 Mar 1991 Location: /pub/ArchiveVol1/unix_lang FILE rw-r--r-- 101131 Jan 6 09:25 occam.tar.Z Host hpserv1.cs.uit.no (128.39.70.50) Last updated 18:22 8 Mar 1991 Location: /pub/languages FILE rw-r--r-- 101131 Feb 2 1989 occam.tar.Z Host jyu.fi (128.214.7.5) Last updated 22:22 7 Mar 1991 Location: /pub/misc/occam FILE rwxr-xr-x 101131 Aug 12 1988 occam.tar.Z Host walhalla.informatik.uni-dortmund.de (129.217.64.63) Last updated 23:14 6 Mar 1991 Location: /pub/programming/languages FILE rw-rw-r-- 101131 Feb 28 1989 occam.tar.Z Host watserv1.waterloo.edu (129.97.129.140) Last updated 23:10 6 Mar 1991 Location: /languages FILE rw-r--r-- 101131 Nov 1 1988 occam.tar.Z Good luck! ----------------------------------------------------------------------------- Adrian Ho, EECS (pronounced "eeks!")
