# Build Linux desktop packages (deb + rpm) for JellyTau.
#
# Produces bundles under src-tauri/target/release/bundle/{deb,rpm}.
# Runs on the existing Ubuntu builder image. NOTE: Tauri has no pacman bundle
# target — the Arch package is built separately with makepkg (scripts/build-arch.sh
# / Dockerfile.arch). `appimage` is also available if you want a portable bundle.
#
# Usage:
#   scripts/build-desktop-linux.sh                 # deb + rpm
#   BUNDLES="deb,appimage" scripts/build-desktop-linux.sh # subset / add appimage
#   OUTPUT_DIR=/app/dist scripts/build-desktop-linux.sh   # copy bundles out

# --bundles overrides tauri.conf.json bundle.targets so this script controls

#
# 🔴 NO_STRIP=true is required for the AppImage bundle.
#
# linuxdeploy (which Tauri downloads and runs to build the AppImage) carries its
# own `strip`, and that copy is too old to parse the `.relr.dyn` section modern
# toolchains emit for RELR relocations. It fails on essentially every bundled
# library:
#
#   strip: libzstd.so.1: unknown type [0x13] section `.relr.dyn'
#   failed to bundle project `failed to run linuxdeploy-x86_64.AppImage`
#
# Ubuntu 23.10+ links with -z pack-relative-relocs by default, so the CI builder
# image hits this exactly as a modern Arch host does. Skipping the strip step is
# linuxdeploy's own documented escape hatch; the cost is an unstripped, larger
# AppImage (~153 MB for a build that bundles libmpv and its ffmpeg stack).
#
# Remove this only after confirming a linuxdeploy release that understands RELR.
