Question about Agent++ Dll

[lsq]

Hi All

With Puchtel's help, I build a agent_pp.dll by VC++6.0.
But when I try the atmmib example,the errors below come:

agent.obj : error LNK2001: unresolved external symbol "protected: static class AgentLog *  DefaultLog::instance" (?instance at DefaultLog@@1PAVAgentLog@@A)
agentpp_notifytest_mib.obj : error LNK2001: unresolved external symbol "protected: static class AgentLog *  DefaultLog::instance" (?instance at DefaultLog@@1PAVAgentLog@@A)
agent.obj : error LNK2001: unresolved external symbol "protected: static class LogEntry *  DefaultLog::entry" (?entry at DefaultLog@@1PAVLogEntry@@A)
agentpp_notifytest_mib.obj : error LNK2001: unresolved external symbol "protected: static class LogEntry *  DefaultLog::entry" (?entry at DefaultLog@@1PAVLogEntry@@A)
agentpp_notifytest_mib.obj : error LNK2001: unresolved external symbol "public: static class Mib *  Mib::instance" (?instance at Mib@@2PAV1 at A)

Do the errors tell me that my dll has some thing wrong? 
If so,how can I correct it? Or Agent++ can't be build to a dll by VC++6?

Any hint will be appreciated.

Regards
