在Windows 10和Visual Studio Community 2019下的Bazel中使用boost

Question

我已经建立了一个简单的C ++程序，该程序利用了boost文件系统模块。要构建程序，我使用Bazel 0.25.0。我正在Windows 10 x64下工作。我安装了Visual Studio 2019社区版本并将其设置BAZEL_VC为E:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC。我已经安装了MSYS2 shell。

这是我的文件（也可以在GitHub上找到）：

工作空间

workspace(name = "BoostFilesystemDemo")

load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

# Boost
git_repository(
    name = "com_github_nelhage_rules_boost",
    commit = "6681419da0163d097d4e09c0756c0d8b785d2aa8",
    remote = "https://github.com/nelhage/rules_boost",
    shallow_since = "1556401984 -0700"
)

load("@com_github_nelhage_rules_boost//:boost/boost.bzl", "boost_deps")
boost_deps()

main.cpp

#include <iostream>
#include <boost/filesystem.hpp>

using namespace boost::filesystem;

int main(int argc, char* argv[])
{
    if (argc < 2)
    {
        std::cout << "Usage: tut1 path\n";
        return 1;
    }
    std::cout << argv[1] << " " << file_size(argv[1]) << '\n';
    return 0;
}

建立

cc_binary(
    name = "FilesystemTest",
    srcs = ["main.cpp"],
    deps = [
            "@boost//:filesystem",
    ],
)

当我尝试构建时，我收到以下错误消息（不幸的是与某些德语混合- Datei kann nicht gefunden werden意味着file not found）

PS E:\dev\BazelDemos\BoostFilesystemDemo> bazel build //...
INFO: Analyzed target //:FilesystemTest (0 packages loaded, 0 targets configured).
INFO: Found 1 target...

有谁有想法解决此问题（使用Bazel 0.25.0或更高版本，Visual Studio 2019 Community Edition，Windows 10 x64，目标应为x64编译源代码）？使用Ubuntu 18.04，一切正常。

切换到另一个提供增强功能的git存储库对我来说也很好。

我还想使用Boost库的其他部分，例如boost signal2，boost log，boost算法和boost计算。

修改BUILD.boost如下：

我克隆了 Rules_boost 存储库并应用了上述更改 - 克隆的存储库可以在 WORKSPACE 文件中直接使用：

workspace(name = "BoostFilesystemDemo")

load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

# Boost
git_repository(
    name = "com_github_nelhage_rules_boost",
    commit = "f0d2a15d6dd5f0667cdaa6da9565ccf87b84c468",
    remote = "https://github.com/Vertexwahn/rules_boost",
    shallow_since = "1557766870 +0200"
)

load("@com_github_nelhage_rules_boost//:boost/boost.bzl", "boost_deps")
boost_deps()

目前，正在运行拉取请求以将这些更改合并到原始存储库中：https://github.com/nelhage/rules_boost/pull/123
