The point of the LGPL is that you have to allow someone to re-link your program against a later / bug-fix version of Qt. Using DLLs are the easiest way to do this, but providing object files and linker instructions is also allowed.

]]> Comment on A developer’s experience with Qt 4.7 for Symbian^3 and Nokia N8 by Johan Paul http://www.johanpaul.com/blog/2011/01/developers-experience-with-qt-47-for-symbian3-and-nokia-n8/comment-page-1/#comment-453 Johan Paul Mon, 30 Jan 2012 15:38:00 +0000 http://www.johanpaul.com/blog/?p=621#comment-453 Hi Sreejith, That's an excellent question and depending on who you ask and what your goals are, you might get different answers. So here's mine. Forget Symbian, it's dead. Android is a good mobile platform if you want to continue targeting the mobile platform. But I would not yet count on using Qt in Android for any serious apps but instead focus on Java with Google's APIs. The future of Nokia is in Windows Phone. If you want to target Nokia phones, then Windows Phone is your choice. And it's a solid platform to develop for with C# (or already with Visual Basic?) and the dev tools are great compared to Android. But from a developer's perspective Windows Phone is more restrictive - think iPhone. But iPhone is doing great so it's necessarily not a bad thing. Hi Sreejith,

I wanted to upgrade my phone to have better memory and storage, since I am running out of resources.But now I am confused, if to go for a nokia 701 symbian belle with just 3.5" screen or move to Android (Qt supported with necessitas - in theory, was not able to make it work completely on the simulator) OR go for a windows phone 7.5 with Visual Basic. I am sure pretty soon many of our fellow developers will reach the same junction. Any thoughts on this? - Sreejith Hi Johan,

Well, the line is actually on this page: http://qjson.sourceforge.net/get_it/ So say "git clone git://gitorious.org/qjson/qjson.git" in the dir where my example is. You need to have Git installed on your system. In Linux it should be available in your distribution, but you might have to install it. In Ubuntu/Debian that would be "sudo apt-get install git". Or you can actually also just download the source tarball for QJSON from here: http://sourceforge.net/projects/qjson/files/ The example should also run in Windows, and Git is available for Windows (http://code.google.com/p/msysgit/), but I have not tested my example in Windows. The .pro file could require some changes, but nothing major. The example is anyway just Qt Quick, Qt and using that JSON parser (for Facebook response parsing) that you can install in the same dir.

It must be the JSON parser that you are missing (and that I unsuccessfully) tried to upload as a subfolder to Gitorious. So go get it from here and put it into a subfolder as in my Gitorious example: http://qjson.sourceforge.net/ Hi!

In all other cases the app will get the same license as kQOAuth. Hence, if you compile in the source code of kQOAuth to your app, your application will also become LGPL licensed.  LGPL lets you only *dynamically* link the library with your application without your application getting the same license as kQOAuth.
