How to run ns3 files out side the scratch or in sub-folder in side the scratch

[Walid Ibrahim]

Hi all 

I want to reorganize the code I am writing so when I created a folder in the scratch so I collect the related scripts I wrote. But when I build the project these error appears.

is there a way to create a sub-folder in the scratch, or run scripts outside the scratch folder?

It's pretty easy.

If you want to have more modularized code, just create a new Module;). To do so, run "create-module.py <YOUR_PROJECT_NAME>" in the src-folder.

After the next configure/build, the files included in the Examples-folder are exetuable and the classes will be compiled.

I would recommend you to read http://www.nsnam.org/docs/release/3.13/manual/html/new-modules.html . That was the best introduction i found.

Thanks for your reply, 

I already create a new Module, and It is working fine, my question how can I run script in the module. 

I mean I created "myModule" in src which contain many files with helper files, then I created a testMyModule.cc in scratch folder to run myModule. 

then I run the testfile.cc using this command ./waf --run scratch/testMyModule

My question can I run the test module like this ./waf --run scratch/myModule/testMyModule?

Just take a look into the wscript-file in the examples-folder in your new module. The first parameter of "bld.create_ns3_program(..." is the ID, which identifies your example. So, ""bld.create_ns3_program('foo',..." means, that you can execute your example by "./waf --run foo".

indeed, it's neat;).

Atm, i don't know a better way than do it by some alias in the shell;).

How can I run a module from scr ?
Like new-crn/src/cognitive
From git hub , I got the code and cognitive module is already created. Bt I can't run it .

Hi,

you don't run a module, you run a script.

Start from the tutorial, it's much easier in that way.
