Thanks to all those who repsonded to my request for opnions on which OS I should use to develop a real-time OS, for a 80386. I want to produce 32bit code for the 386 (from C/C++) I suggested in my original posting that debugging would be easier from DOS (thinking of the Turbo Debugger's 386 debugger). Anyway I received 8 replies, 3 in favour of DOS -1 using Watcom C -1 'cos of the Turbo debugger -1 using Lattice C 5 in favour of UNIX -3 'cos of the software tools -3 'cos of core dump in aiding debugging -1 suggesting gcc / g++ In my opinion the arguments for Unix were stronger than those Dos. The dos people tend to recomend specific products, whereas the Unix people praise the development environment of the OS. ------ Further comments would be appreciated, I'll probable opt for UNIX, so other than Zortech C++ for SCO sysV/386, are there any other '386 compilers out there ? ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: Robert Hartill, Dept Of Computing Mathematics, UWCC, Cardiff, UK. :: :: e-mail : rhl@cm.cf.ac.uk Fax : 0222 371921 :: ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Boys will be boys -And even that .. wouldn't matter if we could only prevent girls from being girls. - Anthony Hope. -------------------------------------------------------------------------------

Up to System V R3.2, there are still some difference between different 386 unices. So be careful! If you buy R4, I would say you will be in very good shape. R4 is bascially the same thing as SUN OS 4.1 (90+% compatible?) and as it is from AT&T is a fairly complete package so different UNIX vendors won't be (except SCO) contaminate it very much. I would like to say that depending how much time you can afford, nowadys with these very stable software developement packages gcc/gdb/g++/bison/perl ...., you never need to pay anything other than your time. You get src too! Regards, Chin Fang Mechanical Engineering Department Stanford University fangchin@portia.stanford.edu
