Addr2Line doesn't work

I remember that with an old SDK I could get Addr2Line to work, but since some SDK (or OS4?) update I've never had any success. All it outputs is:

??
??:0

I am compiling my C++ program with the -ggdb option. When it crashes, I am taking the offset from the Grim Reaper, and passing it to Addr2Line along the lines of:
ppc-amigaos-addr2line -e program_name -f offset2

Or just:
addr2line -e program_name -f offset2

For example:
addr2line -e FooBar -f 0xc9b70r

Does anyone have any suggestions?

And i always use "-g" , not "-ggdb". Maybe addr2line support -ggdb, but its different in compare with plain -g , and in my case i always use -g + add --section=.text to addr2line itself, and all is works.

@ChrisH
An article at HDR Lab recommends a different debug option but I think -g works as kas1e has stated.

@kas1e
Thanks you! Adding "--section=.text" got it working

It's changes in elf.library that have made the difference.

I use the alias "whereis", as in:

"whereis 5689" (you don't need the "0x" prefix)

The alias is "Alias whereis addr2line -j.text -sfe currimage []",

...which gives the name/line number of the source module and the name of the function.

ISTR -gstabs is the recommended debug option to use.
