The parent poster is talking about static linking against a third-party LGPL library, not your own library. In such a case, failing to provide the complete source code, or the original compilation dependencies (.o, .a, .so) and the build chain, is very much against the LGPL.

(Edit: I can't seem to quote the LGPL section 4, so here is a link to it: https://www.gnu.org/licenses/lgpl.html#section4)

There is a massive reluctance in the QT community over this currently -- people want to distribute single-binary applications, and they are told to be careful about doing it.

This exactly. And you straight-up can't do it on Android or iOS.
