Alternatively, run `wails3 task setup:docker` and the build system will use Docker automatically.
### AppImage strip compatibility {#appimage-strip-compatibility}
On modern Linux distributions (Arch Linux, Fedora 39+, Ubuntu 24.04+), system libraries are compiled with `.relr.dyn` ELF sections for more efficient relocations. The `linuxdeploy` tool used to create AppImages bundles an older `strip` binary that cannot process these modern sections.
Wails automatically detects this situation by checking system GTK libraries before building the AppImage. When detected, stripping is disabled (`NO_STRIP=1`) to ensure compatibility.
**What this means:**
- AppImages will be slightly larger (~20-40%) on affected systems
- The application functionality is not affected
- This is handled automatically—no action required
If you need smaller AppImages on modern systems, you can install a newer `strip` binary and configure `linuxdeploy` to use it instead of its bundled version.
