This actually might be a bug on gBuilder.

goto the gini/data directory. You should see a Switch_# directory. There
should be one directory

for each switch in your topology. Remove these directories and the files
inside them. Restart

gBuilder and read the topology file and recompile and proceed.

 

I guess you can do the cleanup using a menu option under the "File" menu
too. I did

not try it. 

 

Please let me know how it goes.
