Bazel-导入头文件时出现问题

Question

我正在尝试导入这些头文件：

AffdexException.h  Detector.h  FaceListener.h   Frame.h          
PhotoDetector.h          typedefs.h
CameraDetector.h   Face.h      FrameDetector.h  ImageListener.h  
ProcessStatusListener.h  VideoDetector.h

它们位于/root/affdex-sdk/include下。下面是我的基本工作区文件的样子：

new_local_repository(
  name = "Boost",
  path = "/usr/local/lib/",
  build_file = "/usr/local/lib/BUILD.boost",
)

new_local_repository(
  name = "OpenCV",
  path = "/usr/lib/x86_64-linux-gnu/",
  build_file = "/usr/lib/x86_64-linux-gnu/BUILD.opencv",
)

new_local_repository(
  name = "AffdexSDK",
  path = "/root/affdex-sdk/",
  build_file = "/root/affdex-sdk/BUILD.affectiva",
)

问题出在AffdexSDK头文件上。这是我的BUILD.affectiva：

package(default_visibility = ["//visibility:public"])

cc_library(
  name = "affdex-sdk",
  srcs = glob(["**/*.so"]),
  hdrs = glob(["**/*.h"]),
)

和带有我的主目标的构建文件，我希望将其转换为二进制文件：

cc_binary(
    name = "video-detector",
    srcs = ["vidDetector.cpp", "include/VideoDetector.h"],
    deps = ["@AffdexSDK//:affdex-sdk",
            "@Boost//:boost",
            "@OpenCV//:opencv",
    ],
    includes = [":affdex-sdk/include/"],
)

以及我需要编译的主要源代码文件的声明：

#include <iostream>
#include <memory>
#include <chrono>
#include <fstream>

#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <boost/filesystem.hpp>
#include <boost/timer/timer.hpp>
#include <boost/program_options.hpp>

#include </root/affdex-sdk/include/VideoDetector.h>
#include </root/affdex-sdk/include/PhotoDetector.h>
#include </root/affdex-sdk/include/AffdexException.h>

#include "/root/sdk-samples/common/PlottingImageListener.hpp"
#include "/root/sdk-samples/common/StatusListener.hpp"

当我运行bazel build //affdex-sdk:video-detector --verbose_failures命令时：

我得到了这个错误：

ERROR: /root/affdex-sdk/BUILD:1:1: undeclared inclusion(s) in rule '//affdex-sdk:video-detector':
this rule is missing dependency declarations for the following files included by 'affdex-sdk/vidDetector.cpp':
 
      '/root/affdex-sdk/include/VideoDetector.h'
      '/root/affdex-sdk/include/FrameDetector.h'
      '/root/affdex-sdk/include/Detector.h'
      '/root/affdex-sdk/include/typedefs.h'
      '/root/affdex-sdk/include/ImageListener.h'
      '/root/affdex-sdk/include/Face.h'
      '/root/affdex-sdk/include/Frame.h'
      '/root/affdex-sdk/include/FaceListener.h'
      '/root/affdex-sdk/include/ProcessStatusListener.h'
      '/root/affdex-sdk/include/AffdexException.h'
      '/root/affdex-sdk/include/PhotoDetector.h'
      '/root/sdk-samples/common/PlottingImageListener.hpp'
      '/root/sdk-samples/common/StatusListener.hpp'

所以我不确定为什么没有包含这些文件，因为我是通过BUILD.affectiva中的glob获得这些头文件的。我在vidDetector.cpp的声明中使用了绝对路径，因为它不会以其他方式获取它们。我不确定如何包含sdk-samples/common hpp文件，但我假设affdex-sdk中的其他头文件都是通过BUILD.affectiva中的glob包含的。请帮帮我。

通常，调试此类问题的好方法是查看复制到沙箱中的内容。有一个关于这个主题的blog post。

现在针对您的特定问题，我认为您应该将includes属性放到@AffdexSDK//:affdex-sdk规则中，并从:video-detector中删除它。然后，您应该能够引用与其包含目录相关的头文件，例如#include <Detector.h>。

您还可以使用strip_include_prefix和include_prefix属性将包含路径调整为您喜欢的路径。
