HI All,

I am trying to install a module which was developed in NS3 v3.21 on v3.30 but getting below error. Pls let me know how to resolve this error. 

The steps which i tried are:

  1. Clone the 5G VANET repository;

  2. Replace the WiFi module with this new module;

  3. Install two module cgame and cgamemac (the codes are located in src/)

  4. Compile the NS3.21 environment by following command:

    ./waf build

  5. Run the demo and algorithm by following command:

    ./waf --run scratch/graphtheoryGreedy

  6. The simulation results will be saved into a text file.

Try changing random-variable.h to random-variable-stream.h because I believe the file name has changed with different in newer releases of ns-3

Cheers,
Adil

This changed as of ns-3.15 release (in 2012).  Also, the variables were changed to inherit from ns3::Object type.

If you want to see what changed (syntax-wise), you can look at the ns-3.14 manual, and compare with a recent release:

https://www.nsnam.org/docs/release/3.35/manual/html/random-variables.html
