Need pre-compiled VM Ubuntu 16.04

[Amar Sinha]

Hi,

I need a pre-compiled VM image of Ubuntu 16.04 with all dependencies as I'm unable to run 

https://github.com/ramonfontes/tutorials 

I have tried everything, but I am still not able to run. I also referred to the book but have had no luck.

You should be able to reproduce them with Ubuntu 18, 20 and 22.04 too.

Respected Sir,

Can you please share any working code for handover using P4 and logs in Ubuntu 20.04?

What do you mean by 'any working code'? What specific problem are you facing with the code?

[Amar Sinha]

Respected Sir,

I'm getting the following error

I see no problem with the code here. It says that you don't have bmv2. ;/

Sir,

I am currently using a Lubuntu 20.04 precompiled image in your repository. After coping with the v1 model file, I'm getting the following error.

Dear Amar,

To work with P4, you need to install all the required dependencies. Most importantly, the code I provided is open and free. If you have some knowledge of P4, you should be able to reproduce my work in multiple ways—not just by running the Makefile, but through other approaches as well.

Sir,

I am currently using a Lubuntu 20.04 precompiled image in your repository. After copying the v1 model file in the handover directory, I'm getting the following error.

In https://github.com/ramonfontes/p4-scenarios I do the same without the Makefile.

Thanks, sir, this is working fine.
