boost binary_oarchive对于不同的编译器工作不同 [英] boost binary_oarchive works differently for different compilers

问题描述

我需要在客户端和服务器之间传输数据。当我把服务器从Windows（msvc140）移动到Debian（gcc 64位）我有一个问题，我的字节流类基于 boost 。他们的档案不同。

I need to transfer data between client and server. When I moved server from Windows (msvc140) to Debian (gcc 64-bit) I've got a problem with my byte stream class based on boost. Their archives are different.

#include <string>    
#include <boost/archive/binary_oarchive.hpp>
#include <boost/iostreams/device/back_inserter.hpp>
#include <boost/iostreams/stream.hpp>

int main()
{
    std::string s;
    typedef boost::iostreams::back_insert_device<std::string> BackInsertDevice;
    typedef boost::iostreams::stream<BackInsertDevice> Stream;
    typedef boost::archive::binary_oarchive BinaryOArchive;

    Stream stream(s);
    BinaryOArchive ar(stream);

    ar << "qwer" << 10;
    stream.flush();

    int sz = s.size();
    // Windows (msvc140):    49
    // Debian  (gcc 64-bit): 57 
}

boost 的两个版本都是1.61.0

Both versions of boost are 1.61.0

推荐答案

这是文件。 http://www.boost.org/doc /libs/1_49_0/libs/serialization/doc/todo.html#portablebinaryarchives

Boost本身没有可移动存档。

There is no portable archive in Boost itself.

您要查看EOS便携式档案馆： https://epa.codeplex.com/

You want to look at EOS Portable Archives: https://epa.codeplex.com/

他们很容易放在你的代码库中，而不是 boost :: archive :: binary_ [io] archive

They're very easy to drop in your code base and use instead of boost::archive::binary_[io]archive
