我已经设置了一个使用boost文件系统模块的简单C++程序。要构建程序,我使用Bazel0.25.0。我是在Windows 10 x64下工作的。我安装了VisualStudio2019社区编辑,并将BAZEL_VC设置为E:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC。我已经安装了MSYS2外壳。
以下是我的文件(也可以在GitHub上找到):

#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;
}构建
cc_binary(
name = "FilesystemTest",
srcs = ["main.cpp"],
deps = [
"@boost//:filesystem",
],
)当我试图构建时,我会收到以下错误消息(不幸的是,它混合了一些德语- Datei kann nicht gefunden werden意思是file not found)

FAILED: Build did NOT complete successfully有人想解决这个问题吗(用Bazel0.25.0或更高版本编译源代码,VisualStudio2019社区版,Windows10 x64,目标应该是x64)吗?使用Ubuntu18.04,一切都很好。
切换到另一个提供boost的git存储库对我来说也不错。
我还想使用boost库的其他部分,如boost signals2、boost日志、boost算法和boost compute。
