我正在尝试使用Bazel来编译和分发基于OpenCV的C++代码,而我正面临着一个我无法解决的问题.

我在源代码上,在Ubuntu 16.04 LTS上构建并安装OpenCV 3.3,并支持CUDA(CUDA 8).我将它安装在标准目录/ usr/local中.

鉴于此,我使用此WORKSPACE文件创建了我的项目:

new_local_repository(
    name = "opencv",
    path = "/usr/local",
    build_file = "opencv.BUILD",
)

opencv.BUILD包含:

cc_library(
    name = "opencv",
    srcs = glob(["lib/*.so*"]),
    hdrs = glob(["include/**/*.hpp"]),
    includes = ["include"],
    visibility = ["//visibility:public"], 
    linkstatic = 1,
)

我可以在我自己的代码中使用它:

cc_binary(
    name = "main",
    srcs = ["main.cc"],
    deps = [
        "@opencv//:opencv"
    ],
)

但是OpenCV中的一些源文件如下:

/usr/local/include/opencv2/flann/flann_base.hpp

包括来自同一目录的头文件,例如:

#include "general.h"

当我使用Bazel构建时,我收到此错误:

ERROR: /home/damien/main/BUILD:1:1: C++ compilation of rule '//main:main' failed (Exit 1)
In file included from external/opencv/include/opencv2/flann.hpp:48:0,
                 from external/opencv/include/opencv2/opencv.hpp:62,
                 from main/main.cc:1:
external/opencv/include/opencv2/flann/flann_base.hpp:38:21: …

我使用 Spring Cloud Data Flow 设置一个读取 CSV 文件的流，使用自定义处理器对其进行转换并记录它：

stream create --name testsourcecsv --definition "file --mode=lines --directory=D:/toto/ --file.filename-pattern=adresses-28.csv --maxMessages=1000 | csvToMap --spring.cloud.stream.bindings.output.content-type=application/json | log --spring.cloud.stream.bindings.input.content-type=application/json" --deploy

文件和 csvToMap 应用程序工作正常，但在日志应用程序中，对于每条记录，我都看到这种异常：

2019-12-03 11:32:46.500 ERROR 1328 --- [container-0-C-1] o.s.c.s.b.k.KafkaMessageChannelBinder$5  : Could not decode json type: adresses-28.csv for key: file_name
