Hello.

Finally I've understood what's wrong. Sorry for giving incomplete answer
yesterday.
In conclusion, you need to change -1.0 of this line:
producerHelper.SetAttribute("Freshness", TimeValue(Seconds(-1.0))); //
unlimited freshness
into 0:
producerHelper.SetAttribute("Freshness", TimeValue(Seconds(0))); //
unlimited freshness
or delete this line which means the same thing.

Actually there are two mistakes in the examples.
The first one is the consumer app OneInterestRequester but not
DumbRequester, which is used only in ndnSIM1.0.
Please do not insert NS_OBJECT_ENSURE_REGISTERED(DumbRequester);  into main
cpp file. It will record the log of main file but not the consumer.
The second one is the freshness time should be greater than zero. 0
(default value) stands for unlimited freshness period in ndn-cxx. -1 is
senceless.

If you fix the time and run it with:
NS_LOG=OneInterestRequester ./waf --run=ndn-simple-with-content-freshness

You are expected to get:
+1.000000000s 0 OneInterestRequester:SendInterest(): [DEBUG] Sending
Interest packet for /no-freshness
+1.000000000s 0 OneInterestRequester:SendInterest(): [DEBUG] >> I:
/no-freshness
+1.057727998s 0 OneInterestRequester:OnData(): [DEBUG] << D: /no-freshness
+2.000000000s 0 OneInterestRequester:SendInterest(): [DEBUG] Sending
Interest packet for /with-freshness
+2.000000000s 0 OneInterestRequester:SendInterest(): [DEBUG] >> I:
/with-freshness
+2.057855998s 0 OneInterestRequester:OnData(): [DEBUG] << D: /with-freshness
+10.000000000s 0 OneInterestRequester:SendInterest(): [DEBUG] Sending
Interest packet for /no-freshness
+10.000000000s 0 OneInterestRequester:SendInterest(): [DEBUG] >> I:
/no-freshness
+10.028863999s 0 OneInterestRequester:OnData(): [DEBUG] << D: /no-freshness
+12.000000000s 0 OneInterestRequester:SendInterest(): [DEBUG] Sending
Interest packet for /with-freshness
+12.000000000s 0 OneInterestRequester:SendInterest(): [DEBUG] >> I:
/with-freshness
+12.057855998s 0 OneInterestRequester:OnData(): [DEBUG] << D:
/with-freshness

The response time of the 2nd "no-freshness" should be about half of other
three interests, indicating the cache hits.
In my computer they are about 0.029s and 0.058s.
