Hi, Sorry, I do not know how to control Bazel's linker command line order. Maybe it would help to define three separate cc_library rules for the three libraries, with the dependencies between them specified -- maybe Bazel will then recognize the dependency relationship and do the ordering correctly. But I don't know.
