fix(build): replace retired Linaro armhf toolchain with Debian's#3070
Merged
Conversation
releases.linaro.org has been retired, so the pi2/pi3 webview-builder's download of gcc-linaro-7.4.1 fails to connect (curl exit 7). Every master Docker build has gone red since, and because publish-latest only advances the floating latest-<board> tags on a fully green matrix, the latest-* images froze — users tracking latest stopped getting any merged fixes. - Install Debian's supported crossbuild-essential-armhf (gcc 14, same arm-linux-gnueabihf- prefix) instead of fetching the dead tarball - Symlink it under the legacy gcc-linaro path the frozen Qt 5 qmake.conf bakes into CROSS_COMPILE, so the pinned WebView-v2026.04.1 artifact needs no rebuild; the app still links against the Raspbian /sysroot, so the target glibc is unchanged - Apply the same swap to the offline toolchain-rebuild path (build_qt5.sh + its Dockerfile) so the dead URL is gone everywhere Validated by building the pi2 viewer image: qmake/make link the AnthiasViewer binary against the pinned Qt 5 libs with the Debian cross-gcc, producing a valid ARM EABI5 hardfloat executable.

Pull request overview
This PR unblocks the failing pi2/pi3 (armhf) webview build by removing the retired Linaro gcc-7.4.1 download and switching to Debian’s supported crossbuild-essential-armhf, while preserving the legacy gcc-linaro-7.4.1-… path expected by the pinned Qt 5 toolchain.
Changes:
- Install Debian’s
crossbuild-essential-armhfin the relevant builder images. - Replace the Linaro tarball fetch with a symlink shim that exposes
/usr/bin/arm-linux-gnueabihf-*under the legacy Linaro directory. - Apply the same approach to the offline Qt 5 toolchain rebuild path (
build_qt5.sh+ its builder Dockerfile).

Addresses Copilot review on #3070: - build_qt5.sh: fail fast with a clear message if the armhf cross toolchain is absent (else the glob expands to a literal and errors confusingly), and use `ln -sf` so reruns are idempotent. - Dockerfile.qt5-webview-builder.j2: the amd64-pin comment referenced the removed Linaro download; the real reason is the pinned Qt 5 bundle's x86_64 host qmake (and the x86_64-hosted Debian cross-gcc).

Issues Fixed
The pi2/pi3 (armhf) image build has been failing on every push to master since 2026-06-10. The
qt5-webview-builderstage downloads the Linarogcc-7.4.1cross-compiler fromreleases.linaro.org, which Linaro has retired — the download now fails to connect (curl: (7) Failed to connect ... releases.linaro.org).Because
publish-latestonly advances the floatinglatest-<board>tags once the entire build matrix is green, two dead 32-bit builds frozelatest-*for every board. Users trackinglatest(e.g. viarun_upgrade.sh) stopped receiving any merged fixes — including the WAL playlist-reload fix (#3062), which is why that bug appeared to persist onlatesteven after it was merged.Description
