agent.cpp

MibTableRow* row = snmpCommunityEntry::instance->
	    add_row(Oidx::from_string(co, FALSE));

snmpCommunityEntry::instance is a NULL ptr.

Alona

Hi Jochen,

First, regarding the unresolved symbols. This is a VC++ compiler issue and those static classes required instantiation. The following code did the trick:

LockQueue * Request::lockQueue = NULL;
LogEntry * DefaultLog::entry = NULL;
Mib * Mib::instance = NULL;
snmpCommunityEntry * snmpCommunityEntry::instance = NULL;

When I try to run the application without arguments, I receive the following errors:

20120224.11:01:57: 7420: (1)DEBUG  : Initialized request_id to 1041.

Oidx Oidx::from_string(const OctetStr& str, boolean withLength) returns NULL pointer and then the application quietly exits. 

Please kindly explain what is going wrong.

Thank you,

Hi,

only some generic advice: Check that the settings of all projects are
the same and do a complete cleanup and rebuild of everything.

Regards,
  Jochen
