可携式归档在GCC下无法编译

Question

我需要在Windows和Linux上序列化/反序列化数据（并在两者之间传输文件）。我想使用Boost序列化库中的可移植二进制存档，可以在示例中找到，例如请参考http://boost-doc-zh.googlecode.com/svn-history/r380/trunk/libs/serialization/example/。这在Windows（VS 2008）上运行良好，但在GCC 4.3.2下编译失败，出现以下错误。请问有人能提供解决方案吗？非常感谢！

虽然这不是直接回答你的问题，但我在使用Google的Protocol Buffers时取得了很大的成功。他们在内部使用并开源了它们：http://code.google.com/p/protobuf/

谢谢，但我知道protobuf，它不适合我的架构。因此，我正在寻找一种Boost序列化的方法来完成它。 - Philipp

Answer 2

#define private public

应该摆脱有关访问私有成员的第一个错误。这有点儿狡猾！但它可以作为一种临时修复，直到您更好地理解整个程序。

我认为这样做是安全的。除了测试它是否有效外，我从未自己尝试过。另一种方法是将其直接传递到编译命令行中 g++ -Dprivate=public prog.cpp -o prog。当然，你有责任确保正确处理私有数据。但如果你正确理解该类的内部结构，应该能够以明智的方式与之交互。 - Aaron McDaid

Answer 3

我使用 g++ 4.1.2 构建，它运行良好。我讨厌 bjam，它很难看到正在发生的事情，而且速度非常慢。 有一个关于弃用头文件的警告，由于这具有弃用友元声明的特征，我希望看到一些旧的东西，但我没有看到。

你是用 bjam 构建的还是尝试将序列化提取到自己的目录中并自己完成构建？因为你的目录结构不完全像包中的结构。
