Hi All,

Finally DJGPP 2.0 is out, so I have decided once again to dredge up all my
DJPP stuff and try to get our products ported across to DJGPP V2. However
the catch is that we have *lots* of assembler code in our products (ove
40,000 lines in the MGL for DOS graphics library) and all this assembler is
written with TASM. Since we have no intention of porting all this assembler
code to GAS, the only option is a conversion tool that will convert between
TASM's .OBJ format and the GNU .o COFF format.

One such tool that I have used with moderate success is the EMXAOUT program
developed by Eberhard Mattes (of EMX for OS/2 and DOS fame), but this has
problems with fixups for private global variables that are declared in the
assembler module, but not made publicly available (actually any global
declared in the assembler module). If the globals are declared in the C
code, and referenced as external's in the assembler code then everything
works fine.

So my quesiton is, has anyone had any experience with converting .OBJ files
to .O files (I know there is another program developed by a demo coder, but
it has similar problems and also has some funky licensing restrictions)? I
would like to try and get EMXAOUT fixed if possible, since it would make an
excellent addition to the DJGPP suite of tools (and the sources are GPL'ed
from memory).

If we can get this working, then we will be able to port all our companies
development tools across to DJGPP (PM/Pro library, Zen Timer, SuperVGA Kit,
MGL graphics library etc).

Please post followups to this group.
