[Winpcap-users] LNK2019: Unresolved external symbol _pcap_close

[Gianluca Varenni]

Just a detail on this: adding wpcap.lib in the linker options for VC++ is 
*not* a workaround. This is how you link a WinPcap-based application. And 
this is how you link whatever application compiled with VC++ with an 
external DLL (if you use DLLs and early binding): you must include the .lib 
corresponding to your DLL in the linker options of your project. The .lib 
file must be provided by whomever gives you the DLL itself.

Just my two cents
