Installing issue about p4-utils HOT 6 CLOSED

Does it work if you do import p4utils?

from p4-utils.

Hi @edgar-costa,

Yes, see the following image.

the only missing module is sswitch_runtime, as you see here it is not there compiler is not able to find this module.

Is it something need to be fixed in the installation file?

Thanks.

Hi @MohamadAlAdraa

Did you install bmv2 and p4c with my scripts? Or only p4utils? I think that might be the problem.

Our install process is the following: https://github.com/nsg-ethz/p4-utils/blob/master/install-tools/install-p4-dev.sh

Try to run the function: site_packages_fix that might fix it.

Please tell me if this fixes it so I can add a note in the installing process.

Hi @edgar-costa,

My last question would be, what is the difference between setQueueMaxSize and set_queu_depth and set_queue_rate?

from p4-utils.

Hi @MohamadAlAdraa ,

Did what I told you to do in the last message fix the issue? I would like to know it.

Answering your questions:

• set_queue_depth sets the number of packets a port queue can hold, so basically its size.
• set_queue_rate sets the maximum rate packets will be emptied from the queue. If you set it at a lower rate than your input packet rate, when queue_depth packets are in the queue, they will start to be dropped.

Hi @edgar-costa,

Yes, I was pulling the main from bmv2 and p4c and changing on them. However, when I pulled the exact commit you are specifying in the installation script and I changed on it, it worked fine.

Thank you for your help.
