Question

我想在tensorflow中添加第三方C库，以便我可以在其中一个示例中使用它。似乎没有任何例子可以遵循，所以任何帮助都将受到赞赏。

这是我使用event2作为第三方C库的工作。

我创造了一个＆＃39; ln -s＆＃39;在tensorflow / third_party中提供event2 / headers：

=> e

THIRD_PARTY /事件2 / BUILD：

ls -al ~/code/tensorflow/third_party/event2
lrwxr-xr-x  1 XXXX  staff  25 May 17 16:03 ~/code/tensorflow/third_party/event2 -> /usr/local/include/event2

/usr/local/include> ls event2
BUILD                bufferevent_struct.h event_compat.h       listener.h           thread.h
buffer.h             dns.h                event_struct.h       rpc.h                util.h
buffer_compat.h      dns_compat.h         http.h               rpc_compat.h         visibility.h
bufferevent.h        dns_struct.h         http_compat.h        rpc_struct.h
bufferevent_compat.h event-config.h       http_struct.h        tag.h
bufferevent_ssl.h    event.h              keyvalq_struct.h     tag_compat.h

在tensorflow / examples / label_image / BUILD中，我添加了对libevent的引用以及使用events2库的测试文件：

licenses(["notice"])

cc_library(
    name = "event2",
    srcs = glob( [ "*.h" ] ),
    visibility = [ "//visibility:public" ],
)

它编译得很好，但是当我运行二进制文件时，我得到以下错误：

cc_binary(
    name = "label_image",
    srcs = [
        "main.cc",
        "my_new_file_using_events.c",
        "my_new_file_using_events.h",
    ],
    linkopts = ["-lm", ],
    copts = [ "-Ithird_party", ],
    deps = [
        "//tensorflow/cc:cc_ops",
        "//tensorflow/core:framework_internal",
        "//tensorflow/core:tensorflow",
        "//third_party/event2:event2",
    ],
)

libevent.a，libevent.dylib和其他libevent * libs位于/ usr / local / lib中。根据nm，event_base undefined。

dyld: lazy symbol binding failed: Symbol not found: _event_base_new

如何解决此链接错误？感谢。

我们不是缺少event2来源吗？另外，我想你想把.h放到cc_library( name = "event2", hdrs = glob( [ "*.h" ] ), srcs = glob( [ "*.cpp" ] ), visibility = [ "//visibility:public" ], )属性中。

这有帮助吗？
