Error loading shared libraries when running the example #79

Open aleksaa13 opened 1 year ago

aleksaa13 commented 1 year ago

Hello everyone,

I am trying to connect aqua-sim-ng and ns3-ai in order to run ML driven UWAN simulations. Thus (in order for aqua-sim-ng to work properly) I am using ns3.27. I was able to run ns3-ai on latest ns3 versions without any problems.

However, when I try to run a+b example I get the following error.

Capture

I can find the library existing and I tried quite a few ways of solving this (updating paths, ldconfig) but nothing seems to work so far.

I feel like I'm missing something quite simple but important, anyone may know why this error keeps popping out?

Hi aleksaa13,

what is the version of ubuntu? (looks like you are using ubuntu linux) I tried ns3.27 on ubuntu 22.04 but even the 'waf' script cannot run. The initial command is ./waf configure --build-profile=debug --enable-examples --enable-tests, and many errors. 

root@94e13f878a72:/home/ns-allinone-3.27/ns-3.27# ./waf configure --build-profile=debug --enable-examples --enable-tests

The above exception was the direct cause of the following exception:
