Hi -
  Are there any other alternatives for unwinding the stack on Linux-ia64
other than the libunwind API ?

thanks,
Umut

Exactly what are you looking for?  Or put differently, what's wrong with
libunwind?

I need to put stack tracing into my program. To use the libunwinding , i
need to link with the library which will cause problems for the customers
who do not have the libunwind library.

thanks,
Umut

ksymoops has the same problem, it needs libbfd and libiberty which are
not always installed.  Link libunwind statically with your program and
use dynamic linking for everything else.

 ld ... -Wl,-Bstatic -lunwind -Wl,-Bdynamic -o ...

People who install the binary have no problems, only people who want to
compile the program themselves need to install libunwind.

Why not link it in statically?  The current libunwind is distributed
under the MIT license, so even if your application is proprietary,
there is no problem with linking it in statically.
