Installation & Run (Linux)

Tauri 2 + React + Vite + Rust + SQLite. Tested on Ubuntu 22.04+ and Pop!_OS.

1. Prerequisites

Node.js 20 (or any LTS ≥ 18)

The Tauri 2 CLI uses optional chaining and crashes with SyntaxError: Unexpected token '.' on Node 14 or older. Check with node -v.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
exec $SHELL
nvm install 20
nvm alias default 20

Rust (stable)

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"

System libraries (Debian / Ubuntu / Pop!_OS)

sudo apt update
sudo apt install -y \
  build-essential curl wget file pkg-config \
  libwebkit2gtk-4.1-dev \
  libssl-dev \
  libayatana-appindicator3-dev \
  librsvg2-dev \
  libsoup-3.0-dev

2. Install dependencies

cd kml_map_tool
npm install

This also pulls @tauri-apps/cli. Rust deps build on first run.

3. Run in development

npm run tauri dev

First run: 5–10 min while Rust deps compile.
Subsequent runs: seconds.
Closing the window stops everything.

The SQLite database is created at ~/.local/share/com.kml_map_tool.app/markers.db on first launch. To wipe it, use Reset DB in the app or delete the file.

4. Build a release binary

npm run tauri build

Output: src-tauri/target/release/bundle/ — .AppImage, .deb, and .rpm (whichever packagers are present on $PATH).

5. Troubleshooting

Symptom	Fix
`SyntaxError: Unexpected token '.'` from `tauri.js`	Node too old. Upgrade to ≥ 18, then `rm -rf node_modules package-lock.json && npm install`.
`error: linker 'cc' not found`	`sudo apt install build-essential`
`failed to find webkit2gtk-4.1`	Install `libwebkit2gtk-4.1-dev`. On Ubuntu < 22.04 only `4.0` is available — upgrade Ubuntu.
Blank white window on Wayland	`WEBKIT_DISABLE_COMPOSITING_MODE=1 npm run tauri dev`
`g_object_unref: assertion 'G_IS_OBJECT (object)' failed` on quit	Harmless WebKitGTK noise. Ignore.
