frenetic not found

[bovenyan]

running
pyretic.py -m p0 pyretic.modules.mac_learner
in the tutorial gives the following errors
./frenetic: No such file or directory.
ERROR:pyretic.core.netkat.netkat:2015-12-07 10:32:03,111: Compiling with the netkat compilation server failed. ([Errno 97] Address family not supported by protocol)

Tried working cloning and running frenetic by
frenetic compile-server --verbosity=error
gives the following error when mininet boots up.

Same problem.
Install frenetic:
On ubuntu 14.04.4 LTS

• add this line to /etc/apt/sources.list
  deb https://dl.bintray.com/arjunguha/deb trusty main
• sudo apt-get update && sudo apt-get install frenetic

Patch for message KeyError: 'queries':
The error appears to be in the pyretic/core/netkat.py file
Replace the function json_to_classifier

def json_to_classifier(fname, qdict, multistage):
from pyretic.core.classifier import Rule, Classifier
data = json.loads(fname)
rules = []
for sw_tbl in data:
switch_id = sw_tbl['switch_id']
for rule in sw_tbl['tbl']:
prio = rule['priority']
m = create_match(rule['pattern'], switch_id)
action = create_action(rule['action'], multistage)
try:
queries = get_queries_from_names(rule['queries'], qdict)
except KeyError:
queries = set()
if rule.has_key('queries'):
pyrule = Rule(m, action | queries, [None], "netkat_query")
else:
pyrule = Rule(m, action | queries, [None], "netkat")
rules.append((prio, pyrule))
#rules.sort()
rules = [v for (k,v) in rules]
return Classifier(rules)

same problem in latest branch on 14.04.

@chelobarreto can you provide right indent format? Thanks~

Check that frenetic is intalled, run frenetic from command line. If it runs then check whereis installed in mi case in /usr/bin/frenetic:

user@localhost#whereis frenetic
/usr/bin/frenetic

Then update the path in /pyretic/start-frenetic.sh

I have the same issue with the provided VirtualBox VM.
Frenetic seems to be missing in the VM.

I'm following this wiki : https://github.com/Resonance-SDN/pyresonance/wiki/PyResonance-overhaul:-Running-example-applications
I solved the frenetic problem after going through the above discussion. But now I'm stuck here, please help...
