Re: DWARF output from Gnat on a Windows platform.

[Marin David Condic <nobody@noplace.com>]

I'll try the switch & see what happens. I had not seen the web page, but 
it looks like there may at least be some information to be gleaned from 
there. Basically, we have something (written in Ada) that is utilizing 
DWARF as its input. We'd like to see if we could use it in the PC world 
under Windows. I don't know if that's possible - hence the fishing 
expedition.

AFAIK, DWARF is something that is connected to ELF with ELF being an 
object file format and DWARF being the debugging data. Gnat may be able 
to generate it, but since Gnat uses native host linkers, is it likely 
that it is going to make ELF/DWARF for a PC? AFAIK, the PC linker isn't 
going to suck up ELF object files so the data (if it could be produced) 
wouldn't do much good. It might work if there was a whole PC based 
ELF/DWARF linking kit that could be used instead of the native PC 
linker, but that's kind of going about it the hard way.

But you don't know until you investigate. Thanks for the info & we'll 
see if anything comes out of this thread.
