Hi Arun,
I'm using a version from savannah mentioned in perftools:
http://download.savannah.nongnu.org/releases/libunwind/libunwind-snap-070410.tar.gz
but I can try downloading from git if it's likely to be more up-to-date.
Thanks very much for the linking suggestion. I couldn't find -lgcc_eh (maybe
because my gcc was compiled with "--enable-shared=libstdc++"?) but I was able
to compile using "libgcc.a libunwind.a libstdc++.a". Are there any drawbacks
to using this instead? Just for curiosity's sake, why does adding libgcc
resolve the multiple definition error?
I guess the warnings in perftools/INSTALL about static linkage apply to my case
(since I'm linking with the *.a files). I will add the --eh-frame-hdr linker
option as suggested. Do you know of any other caveats? I'd prefer to not have
to install these libraries everywhere if possible - do you think this setup
will work given that the app is compiled on a 32 bit machine and run on x86_64?
Thanks again,
--Adam.

Adam, which version of libunwind are you using? I'd suggest using the version
in git.
Can you try -lgcc_eh -lunwind -lstdc++ in that order?
Yes, this is the right mailing list.
