Source code for the LGPL libraries

StitchoMR for macOS includes the free software libraries listed below under the GNU Lesser General Public License (LGPL). Darwich Technologies LLC provides the corresponding source code of these libraries, as used in StitchoMR, to anyone who holds a copy of StitchoMR. We have not changed the source code of these libraries.

1. Where to get the source

We do not host the source archives on this website. The links below go to the upstream projects' own download servers. This page does not link to any copy hosted by us, because there is none on this website. If an upstream link stops working, or you prefer to receive the source from us, use the written offer in section 4.

How these cover the libraries in the application: the Qt Base archive covers QtCore, QtGui, QtWidgets, QtNetwork, QtDBus and QtTest, the platform, style, tls, generic and networkinformation plugins and the gif, ico and jpeg image plugins; the Qt SVG archive covers QtSvg, the svg image-format plugin and the svg icon engine; the Qt Image Formats archive covers the icns, macheif, macjp2, tga, tiff, wbmp and webp plugins; the Qt Translations archive covers the translation (.qm) files; the pyside-setup archive covers PySide6 and Shiboken6; the GEOS archive covers libgeos and libgeos_c.

An upstream single archive of all Qt 6.11.2 sources (about 972 MB) is also listed by the Qt project at https://download.qt.io/official_releases/qt/6.11/6.11.2/single/qt-everywhere-src-6.11.2.tar.xz. We have not computed a SHA-256 for that file.

2. How the checksums were obtained

The SHA-256 values above were computed by us on 2026-10-29 from the files downloaded from the upstream addresses shown, and were reproduced exactly in a second, independent download. For the four Qt archives, the download server also publishes MD5 sums, and they matched the files. For the PySide6 and GEOS archives the upstream servers publish no checksum file we could find, so those two SHA-256 values are our own computation and not a value published by the project.

3. What these archives are, and what we have not verified

The Qt, PySide6 and Shiboken6 binaries in StitchoMR come from The Qt Company's official PySide6 6.11.2 packages (reduced from the universal2 form to Apple silicon by our packaging step). The GEOS library comes from the Shapely 2.2.0 package. We have not modified their source. We have not independently verified that those published binaries were built from exactly the archives listed above without patches, and the Qt Company's binary build configuration is not part of the source archives.

Other components with a pointer to their source: PyInstaller 6.22.3 (GPL-2.0-or-later with an exception that permits use in programs that are not open source; StitchoMR uses PyInstaller's prebuilt bootloader): https://github.com/pyinstaller/pyinstaller/releases/tag/v6.22.3 . All other libraries in StitchoMR are under permissive licences that require notices only; see the third-party and open-source notices.

4. Our written offer

You can download the source from the upstream links above, or ask us for it in writing at support@stitchomr.com or by post to Darwich Technologies LLC at the postal address given on the Open-Source Notices page. We will send it by download link or on physical media for no more than the reasonable cost of the medium. This offer stays open for as long as the version you hold can be downloaded from us, and for at least three years after we last distribute that version.

Nothing in the StitchoMR End User License Agreement limits your rights under these licences. Instructions for running StitchoMR with libraries you have modified: replacing the libraries.
