bazel cc_binary() 创建没有任何符号的 .so 文件？

Question

这是 ubuntu 16.04 中的边框 2.2.0 运行。我已经为 "build" 一个 C++ 库实现了一个宏，并生成了 .a 和 .so 文件。

def add_cc_lib(lib, SRCS, HDRS, lib_defines, lib_includes, lib_copts, lib_linkopts, archive_libs_deps, additional_deps):
    # Define target to create .a for this library
    native.cc_library(
        name = lib,
        srcs = SRCS,
        hdrs = HDRS,
        deps = archive_libs_deps + additional_deps,
        defines = lib_defines,
        includes = lib_includes,
        copts = lib_copts,
        linkopts = lib_linkopts,
        linkstatic = 1,
        visibility = ["//visibility:public"]
    )

    # Define target to also create .so for this library
    native.cc_binary(
        name = "lib" + lib + ".so",
        srcs = [":" + lib] + archive_libs_deps,
        deps = additional_deps,
        defines = lib_defines,
        includes = lib_includes,
        copts = lib_copts,
        linkopts = lib_linkopts,
        linkshared = 1,
        linkstatic = 1,
        visibility = ["//visibility:public"],
    )

其中 archive_libs_deps 和 additional_deps 是当此 add_cc_lib() 宏用于在我的存储库中添加 C++ 库时提供的目标列表。

问题是，虽然这会产生 libfoo.so，但它没有来自 foo.a:

的任何符号

# nm bazel-bin/<path>/libfoo.so
0000000000002008 A __bss_start

我在 Internet 上进行了大量搜索，并尝试了一些没有成功的方法。我在这里错过了什么吗？非常感谢任何帮助。
