c++ - boost 序列化: Linking to libraries

Question

我想使用 Boost 库在我的程序中序列化对象。这是我第一次使用它，它给我带来了一些问题。

在我的程序中，我实现了“序列化”方法并包括以下内容:

#include <fstream>
#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>

现在，当我构建时，出现以下错误:

我不确定问题是因为链接还是与 64 位和 32 位架构有关。

我试过链接:

-L/opt/local/lib/ -lboost_iostreams -lboost_serialization

但是好像没有什么区别。

看起来你的 boost 库包只有 32 位；你必须重建它添加 64 位二进制文​​件，或者设置你的主项目以匹配 boost 库。尝试将您的项目设置为生成 32 位二进制文​​件而不是 64 位二进制文​​件。在 XCode 4.2 中，您将使用项目检查器中build设置的架构部分。
