Custom flatpak packaging for QGIS, (QT6+Parquet)

Forked from https://github.com/flathub/org.qgis.qgis with QT6 & Parquet additions

Usage

Grab a release from https://github.com/linz/qgis-flatpak/releases

flatpak install --user linz_qgis-beb3eecf7d44_build-16.flatpak

flatpak run nz.govt.linz.qgis;

Building

flatpak-builder \
  --force-clean \
  --state-dir=.flatpak-state \
  --disable-updates \
  --ccache \
  --user \
  --sandbox \
  --install ./build \
  --repo=linz \
  --install-deps-from=flathub \
  nz.govt.linz.qgis.json

Bundle into flatpak

QGIS_COMMIT=$(cat nz.govt.linz.qgis.json | jq '.modules[0].sources[0].commit' -r)
flatpak build-bundle \
  --runtime-repo=https://flathub.org/repo/flathub.flatpakrepo \
  linz \
  qgis-linz_${QGIS_COMMIT}.flatpak \
  nz.govt.linz.qgis

Perf:

set a larger cache

ccache --max-size 100G

Set a shared cache location

mkdir $HOME/.cache/flatpak-builder-ccache
export CCACHE_DIR=$HOME/.cache/flatpak-builder-ccache

Caching

To prevent re-downloading files on every build (especially when using --force-clean), you can specify a persistent state directory using --state-dir.

# Create a directory for the cache
mkdir -p .flatpak-state

When using --state-dir, the --force-clean option only cleans the build artifacts within that state directory, but preserves the downloads subdirectory, effectively caching the source files.
