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

标签: c++ windows boost bazel visual-studio-2019

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BAZEL_VC设置为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;
}

已构建

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

当我尝试构建时,会收到以下错误消息(不幸的是,它与某些德语混合-Datei kann nicht gefunden werden的意思是file not found

PS E:\dev\BazelDemos\BoostFilesystemDemo> bazel build //...

有人有解决此问题的想法吗(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库中的其他部分,例如boost signal2,boost log,boost算法和boost计算。

以这种方式修改BUILD.boost

我克隆了rules_boost存储库并应用了以上更改-可以在WORKSPACE文件中直接使用克隆的存储库:

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()

当前,正在运行一个拉取请求,以将这些更改合并到原始存储库中:https://github.com/nelhage/rules_boost/pull/123
