[ndnSIM] About simulation outputs and logging info

[李怿曈 Yitong LI]

Hi,

I’ve tried it. And it gives me the same output. I can start and stop simulation. I wonder whether the result looks good ? Will it generate a report for the simulation or do I need to add sth to the source code?
Here’s the log.

Hi,
Your command needs to look like this
NS_LOG=ndn.Consumer ./waf --run ndn-first --visualize

Alternatively, you can set environment variable with commands such as export.

I’ve attached here, I’m currently using the simple scenario given in the documentation. After running “./waf” and “./waf —run ndn-simple”, I got the outputs below.

From the documentation, I also noticed that “logging” and “debug” mode can be set using “./waf configure —logging/—debug”. But it gave me error showing no such option.

Could you send us your source code? You should be able to see some output.

Hi,

I want to run my own simulation, after using ./waf —run xx command, I can’t see any outputs.

I’ve tried the solution in the template, which uses ./waf configure —debug/./waf configure —logging. But it’s not working, it shows “waf: error: no such option”. “NS_LOG=ndn.Consumer ./waf --run=ndn-simple” is not working as well. I wonder if I need to add some command in the source file to see the outputs?

Thanks,
Caster
