Error while compiling any exercise
Hi,
I'm trying to run the provided exercises in this repository, but all of them failed. This is the output of running make of the basic example:
mkdir -p build pcaps logs
p4c-bm2-ss --p4v 16 --p4runtime-files build/basic.p4.p4info.txt -o build/basic.json basic.p4
sudo python ../../utils/run_exercise.py -t pod-topo/topology.json -j build/basic.json -b simple_switch_grpc
Reading topology file.
Building mininet topology.
P4 switch s1 did not start correctly.
../../utils/Makefile:35: recipe for target 'run' failed
make: *** [run] Error 1
and this is the log of the switch:
Calling target program-options parser

How to solve the issue ?
I'm new to p4 myself so I don't know if this will be helpful but, from the error it shows it's the p4 switch s1. If I'm right, that's the switch which acts as the grpc server and from your error script, it was using the simple_switch_grpc argument. That should mean the grpc server failed to execute. One of the suggestions from the readme files on troubleshooting this is to make stop and trying make run again. However, you are saying "any exercise" failed to run which seems strange because I created mine recently and everything works fine. It might have something to do with your environment. Why don't you try creating everything using the prebuilt .ovf file which you can just import. That works perfectly.
I don't think it's possible to get this error if you used the tutorials VM. You would need to build bmv2 simple_switch_grpc yourself and run configure with --with-sysrepo.
