Hello,

I am trying to find out how to use
the addr2line command with shared 
librairies.

I have non-symbolic output but can't 
get a complete symbolic output. I stop
having source information as soon as the
code enters the shared library.

Thsnks, 

S�bastien.

It looks like you have compiled your shared libraries without dbugging
symbols.

If you use shared libraries straight from your distribution, chances
are they've been stripped of their debugging symbols; this is the
policy on Debian, for example.  On Debian, as a matter of policy, the
-dev package for each library provides a static library with debugging
symbols.  If you link against it, addr2line should work.  I can't
speak for other distros; you may have to recompile the library.
