docs(readme): add Building on Linux section with per-distro deps#134
Merged
Conversation
Closes #94. Reproduced the reported failure on a clean Arch container. The generic "failed to run linuxdeploy" hides a cascade of upstream linuxdeploy / linuxdeploy-plugin-gtk Arch incompatibilities. .deb and .rpm bundles build fine on every distro; only AppImage breaks on Arch. Document: - Debian/Ubuntu (the supported path; our CI runs here) - Fedora/RHEL package names - Arch package list + the --bundles deb,rpm workaround, with the AppImage caveat (recommend prebuilt from Releases) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Closes #94. Document per-distro Linux build dependencies and the AppImage caveat on Arch.
Reproduced #94 on a fresh Arch container. The reporter's generic
failed to run linuxdeployhides a cascade of upstream issues inlinuxdeploy/linuxdeploy-plugin-gtkthat surface on Arch but not Ubuntu (where our CI builds)..deband.rpmbundles build cleanly across every distro tried; only AppImage trips.What the cascade looks like on Arch
xdg-utilsnot in base — Tauri's bundler pre-checks for/usr/bin/xdg-open(it copies the binary into the AppImage) and aborts withxdg-open binary not foundon newer Tauri. Older Tauri (what the reporter ran on v0.7.0) doesn't pre-check, so this leaks through as the genericfailed to run linuxdeploylater.fuse2not in base —linuxdeployis itself an AppImage; withoutlibfuse.so.2it can't self-mount:dlopen(): error loading libfuse.so.2.stripis too old — fails on modern Arch libraries withunknown type [0x13] section .relr.dyn. Workaround:NO_STRIP=true.linuxdeploy-plugin-gtkhard-codes/usr/lib/gdk-pixbuf-2.0/2.10.0/— modern Arch'sgdk-pixbuf2deliberately ships zero loader plugins at that path (Arch splits each format into its own package). Plugin exits withcp: cannot stat '/usr/lib/gdk-pixbuf-2.0/2.10.0': No such file or directory. This one is upstream's bug — not fixable from this repo.So docs only, no code change. README gains a
