[Mono-osx] Debugging

[Seth A. Roby]

I'm trying to get a real debugging environment set up. Right now, I'm  
working in gdb, but the backtraces need the custom mono_backtrace  
macro, variable values are annoying to find, and other such nuisances.  
This would be better if I could hand gdb a dwarf file and have it read  
in my symbols. Looking around, I came across:

 From <http://www.go-mono.com/docs/index.aspx?tlink=8@man%3aoldmono(1)>
> DEBUGGING FORMATS
> The following debugging formats are currently supported:
> stabs
> Writes out stabs debug information.
> dwarf
> Writes out dwarf debug information.
> mono
> Use a symbol file which has been created by MCS. It can be used to  
> get source lines in stack traces.
> The "stabs" and "dwarf" formats support the following options:
>
> filename=FILENAME
> Write debugging information into FILENAME. This file must be run  
> through the assembler to create an object file.
> objfile=FILENAME
> When automatically assembling the symbol file, write the resulting  
> object file into FILENAME.

But this doesn't seem to work with my mono (which makes sense; I'm  
referencing the 'oldmono' man page, here). But I can't find out a way  
to make the "new" mono dump out dwarf data (which would be very handy  
for getting information via gdb, Shark, Instruments, etc).

Does such an option exist?

I also see (sparse) documentation online for the mdb debugger, but  
it's not included on my build and I can't seem to find where to  
download it online.

What are other people using for debugging purposes?
