NS3-DCE: Where should the custom executable files be placed?

[Arun Adiththan]

Hi, 

I'm trying to come up with a custom UDP client/server code using the NS3-DCE module. 

To understand the basics first, I simply modified the file names of existing UDP client/server source files in "examples/". 

No changes are made in the actual code. The modified files are kept in a directory "myscripts/udp-mod/". I then run the

./waf command to generate executable files for both modified UDP server and client. The executable files are in 

"build/myscripts/udp-mod/bin/". 

Now the question is where should I copy these executable files so that I can invoke it like it has been shown in the 

"example/dce-udp-simple.cc" file? 

I tried to place it in both "ns-3-dce/build/bin/" and "ns-3-dce/build/bin_dce/", but when I build and run the code, it gets 

stuck at "Simulator::Run()" (basically the debugging print statement after it isn't running) whereas the same code works

fine with the original UDP client/server executables.

The instructions given here isn't clear to me: https://www.nsnam.org/docs/dce/manual/html/dce-user-newapps.html. 

"echo $DCE_PATH" returns nothing.

Thanks,
