libcamera — Pi 4B / Ubuntu 24.04 ARM64

The workflow builds the pinned Raspberry Pi fork, tests the package in a fresh Ubuntu container, and publishes successful main builds to a commit-tagged release and libcamera-latest. Camera capture must be tested on the Pi. Includes cam with DRM/KMS preview support (no desktop required). Use cam -l to list cameras, cam -c 1 --capture=10 --file for headless capture, or cam -c 1 --capture --display with a locally connected monitor.

Build locally

Run from this directory on Ubuntu 24.04 ARM64:

sudo apt-get update
sudo apt-get install -y devscripts equivs
sudo mk-build-deps --install --remove --tool 'apt-get -y --no-install-recommends' packaging/libcamera/debian/control
JOBS=4 ./scripts/build_libcamera_arm.sh

Output: dist/libcamera/. Use JOBS=1 on low-memory devices.

Install on the Pi

curl -fL -o libcamera-pi4-noble-arm64.tar.gz \
  https://github.com/pennaerial/Dependencies/releases/download/libcamera-latest/libcamera-pi4-noble-arm64.tar.gz
mkdir -p libcamera-package
tar -xzf libcamera-pi4-noble-arm64.tar.gz -C libcamera-package
cd libcamera-package
sha256sum -c SHA256SUMS
sudo apt-get update
sudo apt-get install --simulate ./pennair-libcamera-rpi_*.deb
sudo apt-get install ./pennair-libcamera-rpi_*.deb

SHA256SUMS verifies the package checksum; source-revision.txt records the libcamera source commit. APT installs runtime dependencies.

Before installing, uninstall any previous source build from /usr/local using its original build tree, and review APT's proposed package removals. Rebuild camera_ros and any installed rpicam-apps against the new library. Use --skip-keys=libcamera when running rosdep for this setup.
