Compile fails with libc error

(#797) Bug Fixed desktop packaging
by RexSystem originally by @yofukashino on GitHub

Observed behaviour

Can not compile the desktop app with (GNU libc) 2.42 (version shipped with flatpak runtime org.freedesktop.Platform/25.08). It gives error Linux package exceeds the supported GLIBC_2.35 ABI baseline.

Reproduction steps

  1. Clone the repo
  2. Resolve the rust/pnpm dependencies
  3. Install and enter a bash shell in org.freedesktop.Platform/25.08 (with filesystem/network access as required)
  4. Build the app from within the runtime env.
