Version compatibility issue

[Illakiyavarshini]

I am working in p4 in IPS to update the match action table dynamically, so when i install PI, I faced the issue in grpc

There is a version mismatch with grpc and grpc++ due to which I cant run simple_switch_grpc
"$ pkg-config --modversion protobuf grpc++ grpc
3.18.1.0
1.43.2
21.0.0"
My ubuntu version is 22.04 LTS.

I do not know all of the version combinations of these libraries that work together vs. not, but I do know that every month I test a Bash install script that installs a particular version of grpc, thrift, PI, behavioral-model, p4runtime, p4c, etc. such that they pass most tests and work together without errors.

You can find instructions on downloading a pre-built VirtualBox VM image, or starting from a freshly installed Ubuntu 20.04, 22.04, or 24.04 Linux system and installing the software using that script, here: https://github.com/jafingerhut/p4-guide/blob/master/bin/README-install-troubleshooting.md
