error building v0.8.0 from main branch

[garyn87048]

Hi!

I would like to be able to build rayhunter at home and possibly contribute to the project. I cloned the repository and I'm following the build instructions (https://efforg.github.io/rayhunter/installing-from-source.html). I'm getting two warnings (okay, no big deal) and also getting four compile errors:

error: could not compile `rayhunter-daemon` (bin "rayhunter-daemon") due to 4 previous errors

I did not see rayhunter_orca_only.png at the location above, but rather at rayhunter/daemon/web/static.

I've been a programmer for a while, but I'm new to Rust, so apologies if I'm missing a simple fix.

Thank you for the help!

Gary

You're missing the web UI artifacts. You first need to build the web UI:

x@xps:~/workspace/code/rayhunter$ pushd daemon/web && npm install && npm run build && popd
~/workspace/code/rayhunter/daemon/web ~/workspace/code/rayhunter
... <SNIP> ...
.svelte-kit/output/server/remote-entry.js                            27.51 kB
.svelte-kit/output/server/chunks/internal.js                         72.44 kB
.svelte-kit/output/server/index.js                                  126.39 kB
✓ built in 2.58s

Run npm run preview to preview your production build locally.

x@xps:~/workspace/code/rayhunter$

And then build the rootshell:

x@xps:~/workspace/code/rayhunter$ cargo build -p rootshell --bin rootshell --target armv7-unknown-linux-musleabihf --profile firmware
   Compiling libc v0.2.172

    Finished `firmware` profile [optimized] target(s) in 3.92s
x@xps:~/workspace/code/rayhunter$

Finally, flash onto your device with adb:

FILE_RAYHUNTER_DAEMON=$PWD/target/armv7-unknown-linux-musleabihf/firmware-devel/rayhunter-daemon cargo run -p installer --bin installer orbic

[garyn87048]

Nice! Thank you, and "pilot error" on my part. :-)

My Orbic is attached via usb, so I needed to update the final step to "./target/debug/installer orbic-usb" (added -usb).

Now, it's built and re-loaded and I'm interested to start learning how this thing works!

THANK YOU AGAIN!
