Question

我是使用Boost序列化的新手。我正在使用xml序列化和非侵入式版本。我一步一步地按照教程（来自Boost网站），我的代码工作正常。

当我把我的类（代码分为.h和.cpp加上main.cpp文件）放在命名空间（ns_mytests）中时会出现问题。在这种情况下，编译器（g ++）抱怨并且我有以下错误：

g++ -c -g test.o.d -o build/Debug/GNU-Linux-x86/sources/test.o sources/test.cpp
/opt/local/include/boost/serialization/split_free.hpp: In static member function 'static void boost::serialization::free_saver<Archive, T>::invoke(Archive&, const T&, unsigned int) [with Archive = boost::archive::xml_oarchive, T = ns_mytests::Test]':

make[2]: *** [build/Debug/GNU-Linux-x86/sources/test.o] Error 1
make[1]: *** [.build-conf] Error 2
make: *** [.build-impl] Error 2

我肯定我做错了什么，但我找不到我的错误。

感谢任何帮助。

谢谢， westfork

在命名空间中定义非侵入式save，其中定义了要序列化的类型。

提升序列化和命名空间
