Error while excuting first.py

[Mohamed Bouti]

Hello everyone,

HELP !!!!

This is my first time using Ns3 and i'm kind of struggling to execute first.py i wrote this command :

./ns3 run scratch/first.py

and the message is :

[0/2] Re-checking globbed directories...
ninja: no work to do.

I didn't understand the error...if someone can help me solve this error  or guide me to understand it or what I should  do to solve it !

My seconde remarque when i execute: 

./ns3 run scratch/first

I have this message [0/2] Re-checking globbed directories...
ninja: no work to do.
At time +2s client sent 1024 bytes to 10.1.1.2 port 9

At time +2.00737s client received 1024 bytes from 10.1.1.2 port 9

why it is mentioned in ninja no work to do

I'm really struggling to understand where is the problem

If you can help me please !

best regards

First error is cppyy==3.0 issue. Use cppyy==2.4.2.

Second question : ns3 run ensures the modules are built before running.

 If it says there's no work to do, is because they are built already.

Thank you very much for your response !

when I changed the cppyy version from version 3.0 to cppyy ==2.4.2 it worked !

and this was the result of  ./ns3 run scratch/first.py:

[0/2] Re-checking globbed directories...
ninja: no work to do.

Thank you again !!
