developed an add on to dsr and this is the run time error. kindly  explain to me the reason why i experience this and how to fix it

Comment 2 Tommaso Pecorella 2014-04-24 09:19:19 UTC

In src/dsr/model/dsr-rreq-table.cc there's the following line:
  NS_LOG_COMPONENT_DEFINE ("RreqTable");

Is it present more than ONCE in your sources ?

Can't reproduce the bug.
Not enough info to exclude an error in the user's developed code.
Can't find any duplicate "RreqTable" log component.

23:45:01:~/Development/workspace/ns-3-dev pecos$ grep -r \"RreqTable src/
src//dsr/examples/dsr.cc:  LogComponentEnable ("RreqTable", LOG_LEVEL_ALL);
src//dsr/model/dsr-routing.cc:    .AddAttribute ("RreqTable", "The request table to manage route requests.",
src//dsr/model/dsr-rreq-table.cc:NS_LOG_COMPONENT_DEFINE ("RreqTable");
