Hi All,

  I am trying to create a DLL for nstAgentPluginObject sample program 
given in
http://www.net-snmp.org/tutorial/tutorial-5/toolkit/dlmod/nstAgentPluginObject.c 
using
VC++ 2008 Express Edition.

======================================================================

The compilation and linker settings are as follows

Compiler -> All options

/O2 /Oi /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "_MBCS" /D "_USRDLL" /D 
"_WINDLL"
/D "_UNICODE" /D "UNICODE" /FD /EHsc /MD /Gy /Fo"Release\\" 
/Fd"Release\vc90.pdb" /W3 /nologo
/c /Zi /Gd /TC /errorReport:prompt

Compiler -> Additional options : None

Linker -> All Options

/OUT:"C:\afiles\vs2008\Projects\Project1\nstAgentPluginObject\Release\nstAgentPluginObject.dll" 

/INCREMENTAL:NO /NOLOGO /DLL /MANIFEST 
/MANIFESTFILE:"Release\nstAgentPluginObject.dll.intermediate.manifest"
/MANIFESTUAC:"level='asInvoker' uiAccess='false'" /SUBSYSTEM:WINDOWS 
/OPT:REF /OPT:ICF /LTCG /DYNAMICBASE
/NXCOMPAT /MACHINE:X86 /ERRORREPORT:PROMPT kernel32.lib user32.lib 
gdi32.lib winspool.lib comdlg32.lib
 advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib 
odbccp32.lib

Linker -> Additional options

/VERBOSE:LIB msvcrt.lib netsnmphelpers.lib netsnmp.lib netsnmpagent.lib
==================================================================================

The compilation goes through fine but, the linking failed with 
unresolved external symbol.
I have attached the output below.

Can any of you let me know what mistake am I doing here?
