compiler panicked - tauri

[bburdette]

Trying to compile a tauri project. Worked ok before but not now after trying to get tauri-mobile working.

[bburdette]

this morning it works... made a few changes to configs. Maybe a tauri compile crashes if there's not a proper distDir?

bburdette/zknotes@a681430

If anyone ever looks at this, you can see the changes from crashing to working with

git diff c7f6b00114f5bc85503fdd2b7d9ce6b84d210854

[saethlin]

If anyone ever looks at this,

I looked into this shortly after you reported it. This ICE looks concerning to me; it is from a checked conversion of a usize length to a u32 length for encoding crate metadata.

But I can't reproduce it. I'm on

rustc 1.69.0 (84c898d65 2023-04-16)
binary: rustc
commit-hash: 84c898d65adf2f39a5a98507f1fe0ce10a2b8dbc
commit-date: 2023-04-16
host: x86_64-unknown-linux-gnu
release: 1.69.0
LLVM version: 15.0.7

I run

git clone [email protected]:bburdette/zknotes
cd zknotes
git checkout c7f6b00114f5bc85503fdd2b7d9ce6b84d210854
git submodule update --init --recursive
cargo +stable build

And no ICE. Is there something else I need to do? I have no idea what tauri is.

info

Tauri is a toolkit for hosting a web app frontend in a rust desktop app, or mobile app. I'm just getting started with it. FWIW I also have some android compile targets installed, though I don't know that they would affect anything here. cargo build should just build the desktop app, not the android.

The way I'm setting up my build env is with nix develop. If you happen to use nix and have flakes enabled, you can cd to zknotes/ and call that command. It should install rustc, cargo, and some android build targets.

When this tauri project compiles it apparently looks at the tauri.conf.json file during the process. If that is incorrect it has problems. The one from commit c7f6b00114f5bc85503fdd2b7d9ce6b84d210854 is I think incorrect.

another try

Just gave it another try, checking out the c7f6b00114f5bc85503fdd2b7d9ce6b84d210854 commit on my laptop. I'm calling cargo build from the /tauri/src-tauri directory.

Mostly cargo build compiles, but it hangs on one of the final steps ('app') for 10 minutes or so, and finally panics. Just guessing, but I suspect something from the tauri build.rs returns a bad value after timing out.

[saethlin]

I don't use nix. Running cargo build in tauri/src-tauri still doesn't reproduce the ICE.

I'm also not seeing a hang at the last step of the build. So I think there's something different about my build environment. I see a lot of stuff in the file that describes the flake, things like cargo-tauri that I definitely do not have installed.

I fixed this in #113542 and forgot to link this issue at the time.
