This error message means you are building for x86_64, and the symbols were not found for that architecture. It does not make any statement as to whether the symbols would be found for any other architecture nor whether the software supports or does not support x86_64. It might mean you forgot to specify the name of the library in which the symbols are found, or it could indicate a libc++/libstdc++ incompatibility. Or it could mean there is an architecture mismatch between the program and the library it's using, but since Macs have been x86_64 for many years that's not the first place I'd look.
