Hello, I've got the following class definition: template< class T > class ProxyClass { boost::ptr_vector<T> &e_; ProxyClass( boost::ptr_vector<T> &f ) : e_(f) {;}; template<class Archive> void save(Archive & ar, const unsigned int version) const { size_t o=0; boost::ptr_vector< T >::iterator it = e_.begin(); /*for ( ; it != e_.end(); ++it, ++o ) { const T &t = *( it ); ar & t; }*/ } }; Where it says "boost::ptr_vector< T >::iterator it", the gcc compiler on Linux complains "error: expected ';' before 'it'", while Visual Studio 2005 compiles it fine without any errors. What can I do here? Thanks in advance for your help! S. Lorentz __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
