Compiling error with OFSwitch13 in ns-3.30.1

[Sayed Mahdi Faghih Imani]

Hi Dear Luciano,

I have tested OFSwitch13 release 4.0.0 in ns-3.30.1 on ubuntu 18.04.3 and get these errors:

../src/ofswitch13/model/ofswitch13-queue.cc: In member function ‘virtual bool ns3::OFSwitch13Queue::Enqueue(ns3::Ptr<ns3::Packet>)’:

../src/ofswitch13/model/ofswitch13-queue.cc:90:18: error: ‘Tail’ was not declared in this scope

       DoEnqueue (Tail (), packet);

                  ^~~~

../src/ofswitch13/model/ofswitch13-queue.cc:90:18: note: suggested alternative: ‘Tag’

       DoEnqueue (Tail (), packet);

                  ^~~~

                  Tag

../src/ofswitch13/model/ofswitch13-queue.cc: In member function ‘void ns3::OFSwitch13Queue::NotifyDequeue(ns3::Ptr<ns3::Packet>)’:

../src/ofswitch13/model/ofswitch13-queue.cc:213:18: error: ‘Head’ was not declared in this scope

   for (auto it = Head (); it != Tail (); it++)

                  ^~~~

../src/ofswitch13/model/ofswitch13-queue.cc:213:18: note: suggested alternative: ‘read’

   for (auto it = Head (); it != Tail (); it++)

                  ^~~~

                  read

How can I fix the problems?

Thanks a lot.

Hi,

I didn’t have time to prepare a new module version that is compatible with ns-3.30.1 yet. But, from what I see, i believe that these errors are related to some changes in the queue API, specifically this one: https://gitlab.com/nsnam/ns-3-dev/commit/dc074293d53d9542919bc53cffbe978a8f5bf2ed. Maybe you can edit your /src/ofswitch13/model/ofswitch13-queue.cc file, replacing Head() and Tail() by begin() and end (), respectively. I hope it will work.

Hi,

Thank you for your guidance. You are right. I replaced the Head() and Tail() by begin() and end () respectively and the compile is done complete.
