Hi everyone of the list,
I need a small infomation about Qt.
I found the following on the Trolltech site:
__________________________________________________________________
Why is there no Open Source (GNU GPL) version of Qt on Windows ?
We have regrettably not found a way of making GPL versions for Windows
available without risking the very business model we depend upon to be
able to further develop and support Qt.
Please note that if you make the source code for your project available
and your license allows it, any holder of a commercial Qt Windows
license can create binaries for your project.
__________________________________________________________________
Is this really true? I can't believe that QGIS bases on this libs, which are
not GPL for Windows platforms. So, I guess I'm missing some point. Where can
I find the completely GPL'd?
Can someone help me?
Sincerely,
Andrea

Hi Andrea

QGIS is currently using a QT version which is free for nocommercial use, not
GPL. This version is included in a new QT book.
But it's limit compared to the GPL version under Linux.
Afaik the XML and socket classes (and some others) are missing and that limits
the furter compilation under windows. Another point is, that it's not working
with auto* (automake, -conf) build, you have to use a VC++ project and can't
link it with some libraries (geos) as they need auto*.
One of the QGIS developers (mcoletti) is working at a US university and has
access to an enterprise QT version. So he will try to build everything for
windows in the future.
As I'm not 100% sure with everything I'll forward the mail also to the
qgis-devel list.
Ciao,
Jens
Hi Jens,
thanks you very much for the very exhaustive answer.
Cheers,
Andrea

Yes, Qt is non-free Software for Windows
and Trolltech has mainly a proprietary business model
which is driven by Qt's popularity with KDE.
I can't believe that QGIS bases on this libs, which are
not GPL for Windows platforms.
Freegis.org has some alternatives to qgis,
like Thuban and OpenEV that are based on different GUI libraries
but do not have the same level of GRASS support.
(OpenMAP and Jump suffer from the Java-Trap with is also not nice.)
So, I guess I'm missing some point. Where can

KDE have quite some success to use the X11 GNU GPLed version
of QT on windows, mostly with cygwin.
They also attempt a port of that version to native w32 api.
