It's likely that the name mangling used by the C++ compiler that built
that library is different from the name mangling used by the version of
G++ you're using, so the function names that the linker sees are
different. Name mangling is just one of many differences between
the object code generated by different C++ compilers. You can't link
together C++ object files (including libraries) unless they were built
by the same compiler or by compilers that follow the same application
binary interface (ABI) for C++.
for some general information about issues that affect interoperability
of C++ compilers.
