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
