[AGENT++] linking error, msec.cpp:277: undefined reference to `Snmp_pp::msec::m_localtime_mutex'

[Gens]

Hello,

I wrote a short program to get some (switch) information only. But I get 
the linking errors


...
Building target: snmp++get

... and I do not understand why there are no compiler errors and I have 
no clue what to do and how to avoid the linker errors.

Can anybody help?

If you need more detailed information please ask.


Thank you very much in advance.
