Our addr2line will depend on libdwarf, while our libdwarf is still on
planning stage, so...

Hi,

There was some bugs on nm/dwarf_line_number.c, and fixed now.

Would you test that ?

FYI, you need to compile test target with debug option, -g in GCC.


There is some limit on dwarf_line_number.c,

it does not print path if there is not 'include directory' information.

But GNU nm shows compiled path.

What is the status of nm/dwarf_line_number.c, it seems to have
everything that addr2line would need :) Does it work?, nm -l does not
show any line info.. /me investigates.

I'm not sure about nm/dwarf_line_number.c, just did a little test and
nm -l doesn't work for me either.

This needs more investigation. By the way nm/dwarf_line_number.c should
be integrated into libdwarf later.
