packaging: add GNU Guix package (CLI + GUI) with the PySide6 libGL fix
Adds packaging/guix/vaptvupt.scm so VaptVupt is reproducibly installable on GNU Guix (guix package -f). The GUI launcher sets LD_LIBRARY_PATH to the Qt6 leaf libraries PySide6 needs but does not carry in its RUNPATH — libGL (mesa), libxkbcommon, the X11/xcb family, libzstd (from zstd's "lib" output), harfbuzz, icu, wayland, glib, dbus, ... Without them, `import PySide6.QtWidgets` fails with "libGL.so.1 / libzstd.so.1: cannot open shared object file" and the GUI prints "requires PySide6 or PyQt6" on Guix (which has no global /usr/lib to satisfy them). Qt's own libraries are deliberately excluded from LD_LIBRARY_PATH so they resolve via PySide6's RUNPATH (a second copy causes private-API symbol clashes). Also puts python-shiboken-6's site-packages on GUIX_PYTHONPATH. Verified: full PySide6 QtWidgets/QtGui/QtCore import + QApplication, and the windowed GUI launches, on this Guix system.

|

;;; Source-only build (no vendored libraries): the CLI links only libc/libm/
|

;;; pthread from the store.
|

;;;
|
||||
;;; Install into your profile (additive; keeps everything else):
|
||||
;;; guix package -f packaging/guix/vaptvupt.scm ; installs the GUI
|
||||
;;; guix package -e '(@ (guix) …)' — or, for the CLI on its own:
|
||||
;;; guix install -f packaging/guix/vaptvupt.scm ; (last expr = GUI)
|
||||
;;; The last expression is the GUI, which carries the CLI as an input; to get
|
||||
;;; the `vaptvupt` command in your profile too, also run:
|
||||
;;; guix package --install-from-expression='(begin (load "packaging/guix/vaptvupt.scm") vaptvupt)'
|
||||
;;;
|
||||
;;; GUI-on-Guix note: PySide6's Qt6 links several leaf libraries (libGL from
|
||||
;;; mesa, libxkbcommon, the X11/xcb family, libzstd, harfbuzz, icu, ...) that are
|
||||
;;; NOT in its RUNPATH. The launcher therefore sets LD_LIBRARY_PATH to those
|
||||
;;; libraries (see %gui-runtime-libs). Without this, `import PySide6.QtWidgets`
|
||||
;;; fails with "libGL.so.1: cannot open shared object file" and the GUI prints
|
||||
;;; "requires PySide6 or PyQt6". Qt's OWN libraries are intentionally excluded
|
||||
;;; from LD_LIBRARY_PATH — they resolve via PySide6's RUNPATH; forcing a second
|
||||
;;; copy causes Qt private-API symbol clashes.

"VaptVupt (formerly Zupt) is a pure-C11 backup compressor with native

post-quantum encryption. Two in-tree PQ modes: @code{--pq} hybridizes

ML-KEM-768 (FIPS 203, validated against OpenSSL) with X25519 (recommended), and
|
||||
@code{--pq-only} uses ML-KEM-768 alone for @dfn{PQ-only} compliance postures.
|
||||
Payload protection is AES-256-CTR + HMAC-SHA256 Encrypt-then-MAC with a fresh
|
||||
random per-block nonce and measured constant-time tag comparison; AES-NI/SHA-NI
|

dispatch at runtime; the embedded VaptVupt 2.60.4 LZ+ANS codec ships

CBMC-verified BCJ filters. Password mode uses PBKDF2-SHA256. The tool is
