Solaris/g++ linking problems

I am trying to write a C++ program that uses Entrust encryption.
Entrust supplies header files and *.so files that (apparently) are
created using Sun's C++ compiler. My office doesn't want to spend any
money on this, so I'm using g++.


The compile phase goes fine, but I wind up with "undefined symbol"
entries in the link step. Running the nm utility to see what the
symbols in the object module and the *.so files are, I come up with
things like this:


_Z14EntLogToStrings in the object and __1cOEntLogToString6Fh_pkc_ in
the *.so
_ZN7EntFile19GetConstructorErrorEv (object)
__1cHEntFileTGetConstructorError6M_h_ (*.so)


I suspect that g++ uses a different name mangling convention than the
Sun compiler that created the *.so files. Is this a reasonable
diagnosis? Is there anything that can convert the *.so files into
something that I can use?
