Hi,
BOOST: 1.37
Linux version 2.6.9-efsm (root_at_vizzini) (gcc version 3.4.6 20060404 (Red Hat
3.4.6-3)) #3 SMP Mon Dec 4 13:14:15 CST 2006

I recieve the following link error:
*undefined reference to `void
CommandRequest::serialize<boost::archive::xml_iarchive>(boost::archive::xml_iarchive&,
unsigned int)'*

while compiling the following class:

======H======
#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/shared_ptr.hpp>

class CommandRequest
{
public:
    CommandRequest();
    CommandRequest(int requestID, int commandType);
    ~CommandRequest();
    int requestID() const;
    int commandType() const;

protected:
    int requestIDM;
    int commandTypeM;
    friend class boost::serialization::access;
    template<class A>
    void serialize(A& archive, const unsigned int);
};

BOOST_SERIALIZATION_SHARED_PTR(CommunicationObjects::CommandRequest)

======CPP======
CommandRequest::CommandRequest()
    : requestIDM(0),
      commandTypeM(0)
{
}

CommandRequest::CommandRequest(int requestID, int commandType)
    : requestIDM(requestID),
      commandTypeM(commandType)
{
}

CommandRequest::~CommandRequest()
{
}

int CommandRequest::requestID() const
{
    return requestIDM;
}

int CommandRequest::commandType() const
{
    return commandTypeM;
}

template<class A>
void CommandRequest::serialize(A & archive, const unsigned int /* version
*/)
{
    archive & requestIDM;
    archive & commandTypeM;
}
template void
CommandRequest::serialize<boost::archive::text_oarchive>(boost::archive::text_oarchive&
archive, const unsigned int version);
template void
CommandRequest::serialize<boost::archive::text_iarchive>(boost::archive::text_iarchive&
archive, const unsigned int version);

Please let me know if you can help me out.
