I am trying boost::mpi on a big code & getting the following error message from mac mpiC++ (same from an intel super-computer). Can anyone pick out something quickly from that to help please or do you need to see more? I'd like to figure out what I did to not do it! :)

Thanks!

It would be nice if you used nm -C to get namespace::class::method

instead of gcc's mangled mess.

How do you do this?

$nm -C prog_or_lib | grep $(nm prog_or_lib | grep _Z[gcc mangle] | cut

-d' ' -f1) in terminal.

All I can see is boost::mpi::detail::ignore_skeleton_oarchive followed

by template args and overloads,

boost::archive::detail::interface_oarchive followed by template args

and overloads, and boost::serialization followed by template args and

overloads.

Run nm -C to get human-useful symbol names in the backtrace.

c++filt is your friend.

Demangled backtrace:
