The package runs cargo auditable build without disabling default features, so the new static feature builds the vendored Phosh tree. That tree derives its layer surface from the fork-only GtkPlain type, but this dependency list provides stock GTK packages, including gtk+3.0-dev, and no custom GTK package or path. The internal Meson build therefore cannot compile, causing the APK build to fail. Provide the GtkPlain-capable GTK dependency or disable the static build until it is available.

The package metadata still declares the GTK3, glib 0.18, libhandy, and system-libphosh Rust packages, while the application now uses gtk4-rs 0.11, glib 0.22, libadwaita, signal-hook, and a vendored Phosh build. Because debian/rules runs plain cargo build, clean builders receive only this incomplete Build-Depends set and fail. The GitHub workflow hides part of the problem by separately running apt build-dep phosh; please update debian/control to declare the actual Rust and native build dependencies.

Just as a heads up: once we landed https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/10387 it should be possible to rebase the GTK side |

the emergency menu and triggering the call action, then assert the expected

still prevents this end-to-end flow.

Port phrog to GTK4/libadwaita on top of #213’s Guido Phosh GTK4 dependency layer.
maincontinues GTK3 stable releases while the parallel GTK4 series waits for the wider upstream migration. Remaining migration work is tracked in #215.The stack is #211 → #186 → #213 → #209 (stack #214). Static embedding is an independent build option: plain Cargo dynamically links installed GTK4 libphosh, while
cargo vendored-phosh <command>embeds the checked-in native sources. The two GTK4 layers remain draft; the lower GTK3 work can land separately.Validation at the current source: complete local Phoc suites pass in both modes (2 unit tests and 6 integration tests each), along with all-target builds, strict Clippy, formatting, and executable link-mode checks. The embedding source-refresh regression passes. The pinned ABI checks pass 21 size/alignment comparisons and 12 constants; they do not prove field offsets, vfunc behaviour, or future upstream compatibility. The final native CI image also builds locally. #213 contains the published #186 base and this PR has no
phosh/diff.Remote validation: the matching image published successfully, and both system and bundled build/test jobs pass at
9787b781. The run includes the system test-recordings artifact. Demo-video generation is separate from these completed build/test checks. The inherited base PR workflow still selects a legacy Dockerfile-only image hash and fails before compilation; alignment with the GTK4 branch workflow remains tracked in #215 / #206.Remaining gaps include automatic active-call page pinning (#100), call-error/cancellation coverage and GtkPlain teardown diagnostics, schema installation (#184), broader timing cleanup (#187), GTK4 packaging/snapshots, and final upstream ABI compatibility.
