Question

我创建了一个文件组规则，在一个标签中包含库的所有.proto文件。

filegroup(
    name = "protos_all_src",
    srcs = glob(
        ["**/*.proto"],
        exclude = [
            "protobuf/worker.proto",
            "protobuf/worker_service.proto",
            "protobuf/master.proto",
            "protobuf/master_service.proto",
        ],
    )  
)

tf_proto_library(
    name = "protos_all",
    srcs = ":protos_all_src",
    ),
...
)

但奇怪的是这种格式的另一条规则失败了：

cc_library(
    name = "lib_internal",
    srcs = glob(
        [
            "lib/**/*.h",
            "lib/**/*.cc",
            "platform/*.h",
            "platform/*.cc",
        ] + tf_additional_lib_srcs(),
        exclude = [
            "**/*test*",
            "platform/**/cuda.h",
            "platform/**/stream_executor.h",
        ],
    ),
    hdrs = [
        "lib/core/blocking_counter.h",
        "lib/core/refcount.h",
        "lib/gtl/edit_distance.h",
        "lib/gtl/int_type.h",
        "lib/gtl/iterator_range.h",
        "lib/gtl/manual_constructor.h",
        "lib/gtl/top_n.h",
        "lib/io/iterator.h",
        "lib/io/match.h",
        "lib/jpeg/jpeg_handle.h",
        "lib/png/png_io.h",
        "lib/random/random.h",
        "lib/random/random_distributions.h",
        "lib/random/weighted_picker.h",
        "lib/strings/ordered_code.h",
        "lib/strings/proto_text_util.h",
        "lib/strings/regexp.h",
        "lib/strings/scanner.h",
        "lib/wav/wav_io.h",
        "platform/demangle.h",
        "platform/denormal.h",
        "platform/platform.h",
        "platform/tensor_coding.h",
        "platform/tracing.h",
    ],
    copts = tf_copts(),
    linkopts = ["-ldl"],
    deps = [
        ":protos_all_cc",
        "//tensorflow/core/platform/default/build_config:platformlib",
        "//third_party/eigen3",
    ],
)

请注意protos_all_cc规则为dep。

如果我回到

tf_proto_library(
    name = "protos_all",
    srcs = glob(
        ["**/*.proto"],
        exclude = [
            "protobuf/worker.proto",
            "protobuf/worker_service.proto",
            "protobuf/master.proto",
            "protobuf/master_service.proto",
        ],
    ),

一切正常。

我希望第一种和第二种格式完全相同。我缺少什么？

编辑：此处定义tf_proto_library：

https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/platform/default/build_config.bzl#L26

并且此处定义了cc_proto_library：

https://github.com/google/protobuf/blob/master/protobuf.bzl#L109

Answer 1

您可以粘贴实际代码和您收到的错误消息吗？看起来有几个问题，我不确定哪些是复制粘贴错误，哪些是代码。

我猜你遇到的问题是你不能在cc_library规则中将文件（也不是文件组）列为deps，而":protos_all_cc"是一个文件组。 deps必须是其他cc_libraries（它是“此规则应链接在一起的内容”）。但是很难说出错误信息和protos_all_cc的定义。

Answer 2

srcs属性应该是一个列表，因此您对protos_all的定义应为

tf_proto_library(
    name = "protos_all",
    srcs = [":protos_all_src"], # note the list here
    ...
)

也许这只是问题中的一个错字，真正的问题是别的吗？当我尝试Permission denied方法时，我会遇到奇怪的filegroup问题。

Bazel规则和文件组不一致
