我试图找到一个很好的例子来说明如何使用这些二进制宽字符版本的 boost 的序列化内容。我拼凑了一些代码来尝试让它工作，但不幸的是，在尝试编译它时，我被链接器错误轰炸了。
这是我的代码，以防我做任何明显错误的事情：
#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <boost/archive/binary_woarchive.hpp>
#include <boost/archive/binary_wiarchive.hpp>

public:
testClass()
{
}
testClass(const int intInput, const std::wstring stringInput, const float floatInput01, const float floatInput02)
{
ourString = stringInput;
testInt = intInput;
testFloat01 = floatInput01;
testFloat02 = floatInput02;
}
~testClass()
{}
int testInt;
std::wstring ourString;
float testFloat01;
float testFloat02;
int ReturnTestInt()
{
return testInt;
}
float RandomStuff()
{
float alpha01 = 26.9;
alpha01 /= 2;
return alpha01;
}

};

objectStorage.push_back(testClass(1, L"test\0", 9.14f, 6.662f));

以下是错误：
