How to build simple_switch / simple_switch_grpc on Ubuntu 24.04 ? about behavioral-model HOT 4 CLOSED

What is the actual error message? Maybe the behavioral model should also take the FetchContent route to gain control over its dependencies. It still uses autotools...

I will add a comment with those details later after making a fresh build attempt.

In my earlier install scripts, I installed protobuf and grpc packages from source code, and I always did so with the same version of the grpc and protobuf source code across Ubuntu 20.04 and 22.04.

I originally tried to extend that to the same version of grpc and protobuf source code across all of Ubuntu 20.04, 22.04, and 24.04, and that is where things started getting difficult for me to figure out.

More recently, since creating this issue, I have tried using the pre-compiled versions of protobuf and grpc that come with the Ubuntu packages for that, and not installing them from source code, and at least for Ubuntu 22.04 and 24.04 things seem to be working better that way. I may still install from source code for Ubuntu 20.04, since the PI and I think also behavioral-model packages require more recent versions of the protobuf library than are in the Ubuntu 20.04 pre-compiled packages, but I will worry about that a bit later.

Closing this issue, since I have found that by just living with different versions of grpc pre-packaged Ubuntu binaries across Ubuntu 20.04, 22.04, and 24.04 is working for building not only behavioral-model but also everything else that my p4-guide install scripts build (p4c, mininet, tutorials repo, etc.). Current tested working script (kinda alpha-ish, since it has only been working for a week now) can be found here if you are curious: https://github.com/jafingerhut/p4-guide/blob/master/bin/install-p4dev-v8.sh
