A year ago, I created

https://github.com/ratboy666/mtrel

This was a source level as to mac conversion to allow hi-tech c to be linked
with L80 (or PLINK-II, or whatever).

This is not satisfactory because the assembler production from C source
is not always good. And you lose the benefits of ZAS.

So, I have added objtomac.c which converts OBJ to MAC files which can
be assembled.

Consider this "alpha" level -- it works for me, but required reversing of
the OBJ files. I would really like to go directly to REL, but this appears
a bit more flexible. Pull requests on github welcome!

You can use github for any bug reports, or this forum.

Thanks, and have fun
FredW

The structure of the object file of the HI-TECH C compilers is structured in a certain way.
Your program is a bit like HI-TECH's DUMP utility. Unfortunately, it is only available in the MS-DOS version of the compilers. It's called DUMP.COM. Its task is to display on the screen the contents of an object file created by the HI-TECH assembler. As far as I understand, it is more universal and allows you to view the contents of object files created for several types of processors. In particular, for the object file of your OBJTOMAC.OBJ program, it shows the following information (I removed some of the output):

bash-3.2 $ emu2 DUMP.COM objtomac.obj
objtomac.obj
1 IDENT 10
Machine = Z80
32 bit order = 0 1 2 3
16 bit order = 0 1
2 TEXT 509
data 0 500
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

.... ... ...

7 TEXT 441
text 0 432
CD 00 00 E5 DD 6E 06 DD 66 07 E5 21 02 00 E5 21 01 00 E5 21 00
00 E5 CD 00 00 C1 C1 C1 C1 DD 75 FE DD 74 FF 11 02 00 B7 ED 52
28 06 21 00 00 C3 00 00 2A 00 00 CB 7C 20 0A EB 21 06 04 CD 00
00 F2 4D 00 21 09 08 E5 CD 00 00 C1 18 DF DD 6E 06 DD 66 07 E5

.... ... ...

20 END 2

The object file contains 20 records.
The first record defines the car type - Z80 and the byte ordering of int and long types. The rest contains information about program segments, names of variables and functions.

If you figured out the structure of the object file, then you need to make a little more effort and make an analogue of the DUMP.COM program for CP / M. This will be a useful action.

Andrey Nikitin

I can do that -- there are still "guesses" in the definition of "bss" psect (how much data is in it?).
and some other places (are negative relocation additions allowed? are relocations allows
to arbitrary offsets, not just the last data section?) But, I can do a data dumper... email me the
full results of dumping objtomac.obj (fred_weigel@hotmail.com will do). I have only ever used
the Z80 3.09 hitech compiler, so don't really know the msdos variant...
Looking forward to receiving the output that I will match...

1. A cross compiler for DOS can be downloaded from the Tony Nicholson GitHub page
https://github.com/agn453/HI-TECH-Z80-C-Cross-Compiler
2. To run it, I use the DOS emulator - emu2
https://github.com/dmsc/emu2

It compiled fine for me on mac osx. It allows you to run DOS programs from a linux or mac osx environment.
I will send the full output of the object file to e-mail.

I wish you success.

Thanks! I got the email. Yes, that is the data I see in the OBJ file. And it confirms that the objtomac.c
should do its intended job just fine!
