How to build

[tivvit]

Hi I wanted to try this project but I struggle with the compilation

RUST_BACKTRACE=1 cargo build --release

It is trying to read some file but where it should be located?

Thanks

Seems like you are the first user that is not me, because apparently it was completely broken. Should be fixed in this commit https://github.com/ActivityWatch/aw-watcher-window-wayland/commit/19d8d9fb174ff28e2e2dbfcbf0e18c685da65dbe

The issue was simple, there is generated wayland bindings which are generated into src/protocols but the protocols directory didn't exist unless you create it manually (which I have done before). So I simply fixed so the code generating the bindings creates that directory if it doesn't exist.

Thanks for the report!

If you have any more questions feel free to ask!
