Is there is any way to execution of Ns3 program from any location other than ns-3.29 folder

[Arun]

I want to execute NS3 from any location not only  ns-3.29 location

 /home/username/Downloads/ns-allinone-3.29/ns-3.29

I saw one method in internet for adding path to profile like editing ~./profile:

and add

 PATH="$HOME/bin:$PATH:/home/username/Downloads/ns-allinone-3.29/ns-3.29"

 I tried this but not working . Is it possible to execute Ns3 from anywhere ,

Keep in mind that you are executing a program linking to shared
libraries, so typically you will need to extend your LD_LIBRARY_PATH and
your PATH.

The above PATH that you suggest is typically not going to help.

Have a look inside the build/ directory; you will find your libraries
and executables there.

Notice that build/lib contains the libraries. On Linux, try this command:

cd <top-level-ns-3-directory>
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`/build/lib

Now, you need to extend your path to the executable location. These
will be in the 'build/scratch', 'build/examples', or 'build/src'
directory (mirroring the location where they are found in the source
repository).

For instance, let's say you want to run the tutorial program first.cc:

cd <top-level-ns-3-directory>
export PATH=$PATH:`pwd`/build/examples/tutorial

Now you can run the executable 'ns3-dev-first-optimized' from anywhere.
(Note: you may have a different prefix or suffix name on your
executable than I show above).

Hi Tom,

When I tried the command as follows to run NS3 from any location but still says that ./waf not found. My source file is in the scratch folder.

library

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/uname/Data/ns-allinone-3.29/ns-3.29/build/lib

source file

export PATH=$PATH:/home/uname/Data/ns-allinone-3.29/ns-3.29/build/scratch

Arun, see my other email; you do not use Waf if you try to run the
executable directly.
