Building from source on Windows

[jvolker]

Seems like the Developer guide is missing info for Windows.

When running cargo run --bin updater. I got this error:

error: linker `link.exe` not found
 |
 = note: Das System kann die angegebene Datei nicht finden. (os error 2)

note: the msvc targets depend on the msvc linker but `link.exe` was not found

note: please ensure that VS 2013, VS 2015, VS 2017 or VS 2019 was installed with the Visual C++ option

Installing Visual Studio 2019 worked for me.

Then running the game cd game; RUST_BACKTRACE=1 cargo run --release I got:
Das System kann den angegebenen Pfad nicht finden. German for: System can't find path.

Doing this on Windows instead worked for me:

cd game && set RUST_BACKTRACE=1 && cargo run --release

The first problem: This seems like an issue with the Rust installation process in general, at https://www.rust-lang.org/tools/install. I actually don't see the Windows instructions here; I'll try spoofing my user agent and pretend to be a windows machine in a minute.

The second problem: Just made this easier with 6919c24. Before, you had to ensure that ../data/ existed when you ran the game. Now it'll detect the data dir either in the current directory or one level up. I think the first 3 steps in docs/dev.md have always been correct; it's just easy to miss running from the proper directory.

The first problem: As mentioned above this fixed it

Installing Visual Studio 2019 worked for me.

The second problem: Thanks for making this easier. And I double-checked and no matter what directory I'm doing this from I get the error. Also RUST_BACKTRACE=1 as before the cargo command throws Der Befehl "RUST_BACKTRACE" ist entweder falsch geschrieben order konnte nicht gefunden werden.

Ah, I understand now; Windows has a different syntax for setting env variables. Thanks! I'll fix the docs.

Thanks for fixing this.
