Building OpenCV with rules_foreign_cc

问题

我想用Bazel在C++中开始一个新项目。为了构建OpenCV，我想使用foreign_rules_cc。

我已经按照一些教程进行了操作，但是我无法成功构建OpenCV。

这是我的WORKSPACE文件：

workspace(name = "rules_foreign_cc_usage_example")

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

# Rule repository, note that it's recommended to use a pinned commit to a released version of the rules
http_archive(
   name = "rules_foreign_cc",
    sha256 = "2a4d07cd64b0719b39a7c12218a3e507672b82a97b98c6a89d38565894cf7c51",
   strip_prefix = "rules_foreign_cc-0.9.0",
   url = "https://github.com/bazelbuild/rules_foreign_cc/archive/refs/tags/0.9.0.tar.gz",
)

load("@rules_foreign_cc//foreign_cc:repositories.bzl", "rules_foreign_cc_dependencies")

# This sets up some common toolchains for building targets. For more details, please see
# https://github.com/bazelbuild/rules_foreign_cc/tree/main/docs#rules_foreign_cc_dependencies
rules_foreign_cc_dependencies()

_OPENCV_CONTENT = """
filegroup(
    name = "all_srcs",
    srcs = glob(["**"]),
    visibility = ["//visibility:public"],
)
"""

http_archive(
    name = "opencv",
    build_file_content = _OPENCV_CONTENT,
    url = "https://github.com/opencv/opencv/archive/refs/tags/4.8.0.tar.gz",
    strip_prefix = "opencv-4.8.0",
)

这是我在thirdparty目录下的BUILD.bazel文件：

load("@rules_foreign_cc//foreign_cc:defs.bzl", "cmake")
cmake(
    name = "libopencv",
    generate_args = [
        "-DBUILD_LIST=core,highgui,imgcodecs,imgproc",
        "-DBUILD_ZLIB=OFF",
    ],
    lib_source = "@opencv//:all_srcs",
)

filegroup(
    name = "opencv",
    srcs = [":libopencv"],
    visibility = ["//visibility:public"],
)

我得到的错误是：

bazel build --explain=opencv.log --verbose_explanations //thirdparty:opencv
INFO: Analyzed target //thirdparty:opencv (49 packages loaded, 15164 targets configured).
INFO: Found 1 target...
INFO: Writing explanation of rebuilds to 'opencv.log'

INFO: Elapsed time: 292.206s, Critical Path: 290.73s

如果我克隆OpenCV，运行以下命令：

cmake -DBUILD_ZLIB=OFF -DBUILD_LIST=core,highgui,imgcodecs,imgproc ..
make

它可以顺利编译。

I want to start a new project in C++ with Bazel. To build OpenCV I want to use foreign_rules_cc.

I have followed some tutorials, but I have not been able to build opencv successfully.

This is my WORKSPACE:

workspace(name = "rules_foreign_cc_usage_example")
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
# Rule repository, note that it's recommended to use a pinned commit to a released version of the rules

build_file_content = _OPENCV_CONTENT,
url = "https://github.com/opencv/opencv/archive/refs/tags/4.8.0.tar.gz",
strip_prefix = "opencv-4.8.0",
)

This is my BUILD.bazel in the directory thirdparty:

load("@rules_foreign_cc//foreign_cc:defs.bzl", "cmake")
cmake(
name = "libopencv",
generate_args = [
"-DBUILD_LIST=core,highgui,imgcodecs,imgproc",

],
lib_source = "@opencv//:all_srcs",
)
filegroup(
name = "opencv",
srcs = [":libopencv"],
visibility = ["//visibility:public"],
)

The error I get is

bazel build --explain=opencv.log --verbose_explanations //thirdparty:opencv
INFO: Analyzed target //thirdparty:opencv (49 packages loaded, 15164 targets configured).
INFO: Found 1 target...

If I clone OpenCV, run

 cmake -DBUILD_ZLIB=OFF -DBUILD_LIST=core,highgui,imgcodecs,imgproc ..
make

it compiles without any problems.

另一种方法是不使用rules_foreign_cc。这在我以前使用Windows上的Visual Studio时对我有效：
