Marco Allegretti 2ae05312dc docs: correct openSUSE package names verified against rpmfind

- Replace Mesa-libEGL-devel and Mesa-libGLES-devel (do not exist on
  openSUSE) with libglvnd-devel (Khronos EGL/GLES dispatch headers)
- Replace libseat-devel (does not exist on openSUSE) with seatd-devel

Package names confirmed via rpmfind.net against Tumbleweed and Leap
repositories.

Building WEFT OS

Prerequisites

Linux (x86_64 or aarch64). Building on Windows is supported for workspace validation only; runtime components require Linux kernel interfaces.

System packages (openSUSE):

sudo zypper install -y \
  libwayland-devel libxkbcommon-devel \
  libglvnd-devel libgbm-devel libdrm-devel \
  libinput-devel seatd-devel libudev-devel systemd-devel \
  pkg-config clang cmake python3

Rust toolchain: pinned in rust-toolchain.toml. Run rustup show to confirm the active toolchain matches.

Workspace crates (non-Servo)

cargo build --workspace \
  --exclude weft-servo-shell \
  --exclude weft-app-shell

These crates do not require Servo and build in under two minutes.

weft-compositor, weft-servo-shell, weft-app-shell (Linux)

cargo build -p weft-compositor
cargo build -p weft-servo-shell
cargo build -p weft-app-shell

Without --features servo-embed, the servo-shell and app-shell stubs compile and print READY without running an actual WebView. This is the default and the CI baseline.

Servo embedding (optional, slow)

cargo build -p weft-servo-shell --features servo-embed
cargo build -p weft-app-shell --features servo-embed

This fetches and compiles the Servo fork (github.com/marcoallegretti/servo, branch servo-weft). Expect 30–60 minutes on a clean build. Servo's dependencies include SpiderMonkey (C++), which requires clang and python3.

Demo apps (wasm32-wasip2)

Each demo is a standalone crate in examples/. Pre-built app.wasm binaries are committed. To rebuild:

rustup target add wasm32-wasip2
cd examples/org.weft.demo.counter
cargo build --release
# output: target/wasm32-wasip2/release/app.wasm

weft-runtime with Wasmtime

cargo build -p weft-runtime --features wasmtime-runtime,net-fetch

Without --features wasmtime-runtime, the runtime prints READY and exits (stub mode, used in CI on platforms without Linux system dependencies).

Signing packages

weft-pack generate-key ./keys
weft-pack sign ./examples/org.weft.demo.counter --key ./keys/weft-sign.key
weft-pack verify ./examples/org.weft.demo.counter --key ./keys/weft-sign.pub

NixOS VM (requires Nix with flakes)

Build the VM image:

bash infra/vm/build.sh

Run with QEMU:

bash infra/vm/run.sh

See infra/nixos/weft-packages.nix for the package derivations. The outputHashes entry for the Servo git dependency must be filled in before the servo-embed packages will build under Nix.

CI

Three jobs run on every push to main and on pull requests:

cross-platform — fmt, clippy, tests on Ubuntu and Windows (excludes Wayland crates)
linux-only — clippy and tests for weft-compositor, weft-servo-shell, weft-app-shell
servo-embed-linux — cargo check --features servo-embed for servo-shell and app-shell
