Yes, that's the crux of it.

As of late yesterday evening, we've been able to get this to work by 
linking the .obj (PE/COFF) files with ld emitting a PE executable, and 
then using objcopy to convert to the final ELF executable.

Binutils 2.16.1 compiled with "--enable-targets=i386-pe" on a Linux box.


What we had been doing prior was attempting to bypass the objcopy step
and have ld perform the conversion from PE/COFF to ELF directly (with
the appropriate switches, of course).  It's at this point that the reloc
issue popped up.

So, is it safe to assume that attempting the conversion using ld alone 
will not produce a working ELF file in our case?  That instead we should 
use objcopy to produce the final file?

Thanks for your time and patience,
