Hi, I am running third.cc in the examples of ns3. But every time I run using the usual commands, it gives ->

┌─[user@parrot]─[~/Desktop/ns-allinone-3.42/ns-3.42]

└──╼ $./ns3 run scratch/third

You need to configure ns-3 first: try ./ns3 configure Can someone please help me fix the issue? Thanks

There is something unusual in your directory setup, perhaps confusing
the build system.

It is saying that it is using an 'ns-3-dev' directory that is within
ns-3.42 directory:

/home/isfcr/Desktop/ns-allinone-3.42/ns-3.42/ns-3-dev/build

Usually, we would expect to see (for an ns-3 release):

/home/isfcr/Desktop/ns-allinone-3.42/ns-3.42/build

If you want to use ns-3-dev, do not put it within ns-3.42. You can try
to remove this ns-3-dev directory (or move it out of the way) and type:

./ns3 clean
./ns3 configure
./ns3 build
./ns3 run scratch/third

and it should work.
