I am getting the following error when INT configuring spine switches in mininet emulated environment

Anybody have faced similar issue ? Please help me to fix this issue.

Thanks Kohila

Yep. Seeing the exact same error. This repo seems to have been abandoned, may have to start digging in here.

If you found a fix, please do share.

Okay, this required me to ensure that the switch driver (a file called: bmswitchp4_drivers) is correctly built and placed in the ~/install location. You would need to rebuild the switch docker after compilation (make) and installation (sudo make install) of the switch submodule.

Hi gopchandani,

I am getting the same socket error. I tried to ensure the switch drivers, but I am facing core dump. Can you explain in more detail what have you done to make it work ? I really appreciate any help you can provide.
