Since the function is inline, every program calling this function must also link with -lflac, but this is missing in flac++.pc. There are two ways to fix this: implement Chain::Status::as_cstring in such a way that the caller does not need to link with -lflac or add -lflac to the pkg-config file. Regards -- Sebastian Ramacher
