How to compile the latest proto files correctly?

[ABaumher]

I'm coming from the GoG Galaxy Steam integration, where we basically reinvent everything done here, except much worse. I'd simply install this package and import it, but the code i inherited is so bass-ackwards i'm trying to change as little as possible while keeping it working. To give a short rundown, I need to include a different message than what we're currently using, which means a different proto file. I have the proto file and protoc installed, but the output i get is drastically different from what's in our existing code, and also what you have. I get an absurdly long descriptor and no method calls. My previous uses of protocol buffers left them in their base ".proto" format, so i'm a little out of my depth, and following the Python Tutorial got me into this mess.

If you could tell me how to compile the proto file correctly so it matches the expected format you and seemingly everyone else use, that would be much appreciated.

For reference, here is what the base steam messages outputs when i compile using protoc --python_out=.\out .\steammessages_base.proto (Edit: Using Windows Paths. If on Mac/Linux, use forward slashes, of course). Evidently, your base steam messages file looks completely different than this.

Found your makefile, nevermind. For anyone who sees this and cares, you'll need gmake, which you can get on Ubuntu with sudo apt install make (or the equivalent package for other distros). For windows, you can use min-gw or WSL (which is what i did). The command is make pb_update. You may need your python virtual environment configured properly, but that's a project-related thing and out of scope here.

You can also simply copy/paste the commands from the makefile manually if you want. They're just bash commands you can run from a terminal
