Hello, Does anyone know of a good PD/Shareware 68000 cross assembler? - Tony Leneis aleneis@hmcvax.bitnet aleneis@jarthur.UUCP

I've done all development for versions up to 2.42 on MS-DOS machines using an old version of Lattice C. Those #ifdef MSDOS lines let me work around the more brain-dead aspects of that operating system without contaminating the Amiga. Once I get a working version, I ship it off to Jeff Lydiatt (who has done lots of work on both PDC and Sozobon-C to make them useful development tools for the needy). He compiles the source code on his Amiga using Aztec C, and doesn't have to change a single line of code. I guess that makes it sort of transportable, although I can't see what an MS-DOS victim :-) could do with an AmigaDOS object file. You can always use the -s switch to produce Motorola S-records, though. If anyone has ported A68k to any other systems, please e-mail me with the gory details. I'm trying to keep it as portable as possible. I've tried to avoid any dependence on byte ordering (if it runs on an Intel chip I can't be doing too badly :-) but if there are any problems I'd like to hear about them so I can fix them in future versions. (Coming in version 2.6 (Real Soon Now): forward branch optimization and an ARexx interface for error handling!) Charlie_Gibbs@mindlink.UUCP "I'm cursed with hair from HELL!" -- Night Court

Well, I've compiled & run A68K on a VAX, and it does seem to run and
produce .o files. It also has #ifdef MSDOS tests in it, which would
seem to imply that it would run under MSDOS, which would imply some
relatively general portability. (After all, if it will run under
MSDOS, it can't do anything fancy, can it?) It required a few minor
changes to get it to compile--email me for details.
I only just recently compiled it, and I haven't actually downloaded &
linked any of the files that it produced, so take this posting for
what it's worth. Since it just calls open(), write(), &c, the only
problem I could think of that it might have would be byte ordering....
Writing this has prompted me to go off & look at the source just now,
and I believe that I will have to fix byte ordering before it will
work. Luckily, it all the writes seems to go through one routine, so
I only have to make one fix.
