Hello Team,
First off I would like to appreciate Alfonso for his help on my last thread with 6LoWPAN.
Now I need to integrate an SDN controller into my network so it can handle the routing of packets hence improving network quality.
I ask
1) Is it possible to pull this off using the Openflow framework in omnet++

2)I am trying to build the openflow framework which is meant to work with omnet 6 and INET 4.3, the one posted in this link 


but I am getting the errors

make[1]: Entering directory '/home/mininet/omnetpp-6.0pre14/samples/openflow/src'
MSGC: openflow/messages/HF_ChangeNotification.msg
openflow/messages/HF_ChangeNotification.msg:8: Error: Type declarations are not needed with imports, try invoking the message compiler in legacy (4.x) mode using the --msg4 option

make: *** [Makefile:2: all] Error 2
"make MODE=debug -j1 all" terminated with exit code 2. Build might be incomplete.

I already tried with both latest version of omnet6 and omnet6 rebuild 14.
what could be the problem here.
Thanks in advance.

I was able to get it working by using the latest omnet6 and setting INETMANET 4.x as the project reference.
Now to the first question, any hints about how I can do that will be much appreciated.
Also, is there documentation for the Open flow framework and what version is it?

Also, any time I try running any of the ini files in the openflow framework I keep getting this error.

Hello all,
I am having an issue while running simulations with the openflow framework stated above.
The simulation stops running and I get the error below.

I tried debugging then I get the following error.

<!> Error: Cannot load library '../../src//libopenflow6_dbg.so': ../../src//libopenflow6_dbg.so: undefined symbol:  _ZNK4inet16OperationalMixinIN7omnetpp13cSimpleModuleEE14refreshDisplayEv

To fix this I ran the following commands:
make cleanall
make 
Then I rebuilt the framework, however I still get the same errors.

Kindly guide me on how to fix this error.

Thanks.

I cannot reproduce the problem, apparently, the class OperationalMixin has not implemented the method refreshDisplay, but this method is implemented. I try to run one of the scenarios, and it loads the libraries correctly.

You can try also to build using inet-framework, the master branch

Okay.
If I may ask, what combination do you use for yours?
I mean what version of Omnet and INET are you using to build the Openflow framework?

Latest version of inetmanet, and latest version of omnet, I periodocally actualize both
