[Mini-NDN] Mini-NDN dependency issue on Ubuntu 18.04

[Saurab Dulal (sdulal)]

Hi Junxiao,

Thank you for listing out these problems.

Taking into consideration the fact that Mini-NDN is based on mininet and Mini-NDN-Wifi is based on Mininet-Wifi, yes, I agree that Mininet-Wifi should be an optional dependency. We will have some discussion in the coming days and will work to make the necessary changes asap.

Please help us review this patch: https://gerrit.named-data.net/c/mini-ndn/+/6426, it is supposed to fix the last two issues you have noted (hopefully the first one as well) and some other issues too.

Additionally, you can try this box https://app.vagrantup.com/ashiq/boxes/minindn, it comes with Mini-NDN pre-installed.

Thank you

Saurab

Dear folks

I'm trying to setup Mini-NDN (revision 578f2ec695e6918f86f2837068c1f66d2ccf26c3) on Ubuntu 18.04 following the guide in docs/install.rst , and I noticed two dependency issues.
I'm using a Utah Emulab d710 PC with system image urn:publicid:IDN+emulab.net<http://emulab.net>+image+emulab-ops:UBUNTU18-64-STD.

ImportError: No module named mn_wifi.cli
The command given for "install without CCL" is: ./install.sh -mni
I added -q flag for automated installation, which completed without errors.
However, Mini-NDN installed with this command is unusable:
sjx at n:~/mini-ndn$ sudo python examples/mnndn.py
Traceback (most recent call last):
  File "examples/mnndn.py", line 27, in <module>
    from minindn.util import MiniNDNCLI
  File "/users/sjx/mini-ndn/minindn/util.py", line 30, in <module>
    from mn_wifi.cli import CLI as CLI_wifi
ImportError: No module named mn_wifi.cli

It seems that Mininet-WiFi is a required dependency of Mini-NDN, intentionally or not.
If it should have been an optional dependency, the runtime scripts should have necessary checks.
If it should have been a required dependency, the documentation and script should be revised.

/usr/bin/ld: cannot find -lnl-route-3
I also tried the quiet installation command: ./install.sh -qa
The installation completes, and basic verification passes.
However, there's an error in the console output:
/usr/bin/ld: cannot find -lnl-route-3
collect2: error: ld returned 1 exit status
Makefile:1882: recipe for target 'wpa_supplicant' failed
make: *** [wpa_supplicant] Error 1

If I install the libnl-route-3-dev package before installing Mini-NDN, the installation would succeed without the above error.
Please add it to the script.

cp: cannot stat 'topologies/minindn.testbed.conf': No such file or directory
Another error is:
cp: cannot stat 'topologies/minindn.testbed.conf': No such file or directory
cp: cannot stat 'topologies/current-testbed.conf': No such file or directory
These files no longer exist but are referenced in install.sh.

Yours, Junxiao
