dwarf 1, dwarf 1+
dwarf 2
stabs, stabs+
coff, xcoff, xcoff+
mdebug

Also, I'm not sure whether "hp" is an object code format or a debug
format.

HP32 uses SOM (object format). The Debug format used is then stabs.
HP64 uses ELF, in which case you have the choice between stabs or
dwarf2.

Thanks Michael,

open watcom does support dwarf1, and so I tried that, but still nothing.  GDB 
just keeps saying it can't find any debug information.  Shuold gdb 
automatically detect the debug type, or is there an option?

Thanks

Can you post the output produced by running 'objdump -h' on your
executable file?

Re: open watcom

[Michael Elizabeth Chastain]

Well, I think you are stuck:

  gdb doesn't support open watcom.
  open watcom has no documentation that I could find about gdb.
  google "open watcom gdb" did not find anybody talking about
    using open watcom and gdb.

You could ask on an open watcom list if open watcom interacts with gdb,
and if anyone has actually used that combination.

I suggest that you check out the debugger that comes with Open Watcom.

I will file an enhancement request against gdb to add support for
open watcom.  It is a lot of work to add support for a new compiler;
someone would have to volunteer to do this work.

Open Watcom is licensed under the Sybase Open Watcom Public License,
which is an OSI-approved open source license.  So I think it would be
reasonable to consider adding support for this compiler, if a volunteer
steps up.

Yep, I've rechecked my options, and in both the compile and link time, I have 
the debug swtich to use DWARF.

Check the switches for open watcom.  It's likely that you need to
specify debug switches both at compile time *and* link time when
building your program.

gdb automatically detects debug type.

I know that other people have used dwarf 1, and I ran the gdb test
suite on it earlier this year.  So I know that gdb does automatically
detect and use dwarf-1 debug information with gcc -gdwarf.

open watcom

[y2bismil]

Hey guys,

We're exploring a new development environment here, and as part of the 
migration process, I was wondering if its possible to debug code genered by the 
open watcom compiler using gdb.  I've tried unsuccessfully setting the 
debugging in watcom to:  watcom, codeview, and dwarf, but to no avail.

Does anyone know the location of a list of supported debug format by gdb?

thanks all,

Yamin
