3.7. What are my obligations when using Qt under the LGPL

Qt Licensing Qt 5.1

Qt is available under both LGPL and GPL (you choose either one), apart from some new modules introduced after Qt 5.7 like QtVirtualKeyboard, QtCharts etc.. From what you say I gather that you won't use these modules, so you can freely go with LGPL and keep your code private if you wish to LGPL licensing means that you can use Qt in your application, link to it (this part is a bit confused, but it is specifically allowed for Qt thanks to a special exception), and not have to license your application as open source. The Qt library itself, however, is still open source, and you're not allowed to publish new version of Qt without providing the source code. GPL licensing means that.

Der Copyleft-Effekt der GNU LGPL erfaßt in der Regel nur modifizierte Fassungen der Library (Ziff. 2 LGPL). Die Library sollte daher in unveränderter Form genutzt werden. Einbindung durch dynamische Verlinkung Die Einbindung der LGPL-Library sollte durch dynamische Verlinkung als shared library geschehen. Zwar erlaubt die LGPL auch andere Formen der Nutzung, z.B. statische Verlinkung, allerdings nur unter wesentlich ungünstigeren Voraussetzungen. So kann die statische.

This is the recommended solution - it allows the user to upgrade to later versions of Qt easily. 2) can I legally bundle my final *.EXE files even if it's compilation/linkage depends on QT *.LIB files. Do you mean you use the Qt stub .libs to build a dll version or are you statically linking an exe ( no Qt DLLs required)? It must be possible to relink Qt. If you are statically linking Qt this probably means you have to make object or raw library versions of your app available.

Engineer's explanation of LGPL vs. Commercial licensing of products such as Qt for industrial / embedded product development - David Pashley, Direct Insigh As Qt for Android uses the LGPL version of Qt, and it's perfectly possible (and also recommended and supported) to dynamically link in the Qt libraries when creating an app - there are no problems for app developers using Qt for Android.
