我正在尝试构建这个程序：
#include "stdafx.h"
#include <boost/interprocess/shared_memory_object.hpp>
#include <boost/interprocess/file_mapping.hpp>
#include <boost/interprocess/mapped_region.hpp>
using namespace std;
int main()
{
using boost::interprocess;
// Create the file mapping
file_mapping fm("input.dat", read_only);
// Map the file in memory
mapped_region region(fm, read_only);
// Get the address where the file has been mapped
float * addr = (float *)region.get_address();
std::size_t elements = region.get_size() / sizeof(float);
}
但是我遇到了两个问题，主要的问题是我得到了以下错误信息：

我正在使用Visual Studio Express 2013 for Windows Desktop和boost 1.55.0。
我尝试了其他的boost库，没有任何问题...此外，我正在使用x64版本的发布构建。
