# =============================================================================
# WZ Phone — Linux x86_64 Tauri desktop build image
#
# Thin extension of wzp-android-builder that adds the GTK3 + WebKit2GTK 4.1 +
# libsoup-3.0 + AppIndicator dev packages needed to build the Tauri desktop
# app for Linux. Everything else (Rust, Node.js, cmake, pkg-config, cpal
# libasound deps, tauri-cli) is inherited from the base image.
#
# Build:
#   docker build -t wzp-linux-desktop-builder -f Dockerfile.linux-desktop-builder .
#
# Run: driven by scripts/build-linux-desktop-docker.sh (see that file).

# Tauri 2.x Linux dependencies.
# - libwebkit2gtk-4.1-dev: the WebView backend. Tauri 2.x uses 4.1 (not 4.0).
# - libsoup-3.0-dev: HTTP client used by webkit2gtk. Must match its major.
# - libgtk-3-dev: GTK3 headers (webkit2gtk still uses GTK3).
# - libayatana-appindicator3-dev: system tray / status icon. Optional at
#   runtime but tauri-build's feature-detection includes it.
# - librsvg2-dev: SVG rendering in the menu/icon code.
# - libglib2.0-dev: GObject introspection headers (transitive, but explicit).
# - patchelf: used by the tauri bundler to rewrite rpaths in the final binary.
# - file: already in the base, but tauri-build checks for it by name.

# ── webrtc-audio-processing build requirements ──────────────────────────────
# The `webrtc-audio-processing` Rust crate (0.3.x line) links against Debian
# Bookworm's `libwebrtc-audio-processing-dev` apt package (0.3-1+b1), which
# provides the PulseAudio fork of the WebRTC audio processing module. This is
# the library that Pulse's module-echo-cancel and PipeWire's filter-chain
# use for their AEC modes — same algorithm family, runtime-linked via
# pkg-config at cargo build time.
#
# An attempt was made to use the 2.x line with the `bundled` sub-feature
# (which would give AEC3 instead of AEC2) but both the crates.io tarball
# and the upstream git `main` branch hit a `meson setup --reconfigure` bug
# that panics on first-run empty build dirs. The 0.3 line avoids the
# bundled build path entirely and is what we ship for now.
#
# `clang` is listed explicitly because the Rust crate's bindgen may need
# it at compile time depending on the version of the underlying
# webrtc-audio-processing-sys build script.
