Qt 4.6.1 Released

Posted by Jason McDonald on January 19, 2010 · 19 comments

Qt 4.6.1 is now available. Qt 4.6.1 is a patch release, providing bug fixes, performance improvements and documentation fixes. With over 90 entries in the change log, the download and upgrade is well worth the effort.

As usual, you can get all the packages from the Qt Download Page and you can read the latest documentation at http://qt.nokia.com/doc/4.6/index.html.

For those using the public git repository, a “v4.6.1″ tag will appear soon.

As always, your feedback on Qt is appreciated. If you have any comments or bug reports, we’d love to hear from you.
Please file your bug reports at: http://bugreports.qt.nokia.com. If you want to contribute to Qt, all the information you need to get started can be found at: http://qt.gitorious.org.

Good news! But i think something is missing in the changelog:
- Phonon
* Include headers have been changed. The only official method for
including Phonon headers is (missing) or (missing)
. This change was necessary because of (missing)
frameworks on Mac.

I presume you’re referring to the changelog linked above. It looks fine to me in all of Opera, Safari, Arora, Konqueror, Firefox and IE.

The text reads as follows:

– Phonon
* Include headers have been changed. The only official method for
including Phonon headers is or . This change was necessary because of
frameworks on Mac.

@Fabio, @Jason: I told the webmaster about this problem when I noticed it, he must have fixed it in between your messages. I guess Jason also noticed that our blog comments also won’t show the HTML if you don’t escape the &lt and &gt stuff. :-)

Is there a new patch for QtDeclarative?

What’s with you servers for the downloads – and the git repo – both close the connection before the file transfer is complete. For the git repo, it seems its aborted whenever a check-in occurs, which invalidates the snapshot.

I don’t know what the excuse is for the http server. I transfer large files all day and only have this problem with Qt-related things. I get a good rate – 340KBs, bit it stops around 200 megs. I work around this by using one of those file hosting sites that will take a URL, and when its downloaded to there, I download it from the hosted site. And that always seems to work.

Installed it, seems to work ok. Question, I tried to run the imagegestures example on a Nokia5800. Doesn’t seem to work, no gestures are recognized. Any ideas?

Qt for Linux and for embedded Linux are same file…
Am I right?

@precipi: That’s correct, the qt-everywhere source package has the code for all supported platforms. If you want to build for embedded, just add “-embedded” to the configure line.

Thanks, it’s always nice to have a new version. But frankly, I expected more bugs to be fixed :-(

Now that Qt 4.6.1 has been released could we please have an updated release of Qt Declarative (http://get.qt.nokia.com/qml/qt-4.6.0-declarative.tar.gz). Thanks!

nice release Qt4.6.1 long with QtCreator1.3.1

12 QtDeclarative January 22, 2010 at 6:54 am
 

@chaz6: we will release a Qt Declarative package for Qt 4.6.1. We’re not quite in sync with Qt releases, so it will probably appear in about 2 weeks.

OK, nice release, BUT, I am very sorely disappointed, and a little frightened, by the extremely buggy behavior on a Mac OS X 10.6.2 (on a Mac Pro).

Qt/Designer.app and Qt/Assistant.app both coredump on exit.
Assistant is completely useless since it does not display text.
Any of the apps, examples or demos that have a font dialog will crash (in x86_64 which is standard) when accessing the font box.

Wow, and this all after 10 minutes with your codes. Do the developers have a Mac at all?

I figure if Designer and Assistant are so buggy, probably everything created using Qt will be equally buggy on a Mac, so in essence, non-functional. I am now looking forward to Qt4.6.2 and hope that one actually works.

I fortunatly don’t have any of these issues with 4.6.1 on my MacPro+10.6.2 (using Carbon).

15 tachion January 24, 2010 at 9:04 pm
 

Maybe the problem is that I use Cocoa, as the installation page suggests. I hadn’t considered that Carbon may be the better choice.

Hi, I am reading error message below while executing configure for qt-everywhere-opensource-src-4.6.1.tar.gz

/home/jacob/qt-everywhere-opensource-src-4.6.1/src/corelib/global/qglobal.cpp:17
25: error: cannot convert ‘OSVERSIONINFOW*’ to ‘_OSVERSIONINFOA*’ for argume
nt ‘1’ to ‘BOOL GetVersionExA(_OSVERSIONINFOA*)’
make: *** [qglobal.o] Error 1

FYI, I use cygwin on Windows XP. Do you have any recommendation ?

cannot load mp3 url using phonon in this version. going into the error state and printing “buffreing failed”. Even the qmediaplayer example application has the same problem.

I downloaded the latest “Qt SDK for Windows” from http://qt.nokia.com/downloads/sdk-windows-cpp and find that I am unable to rebuild the libraries. I have tried using MS Visual Studio 2008 on Windows XP Pro, as well as MingW32 on XP Pro and on Vista.

It seems that the “solution” to this problem has been known to readers of the TrollTech forums for several months now. (see: http://labs.trolltech.com/forums/topic/896 ) Any chance someone could “fix” the SDK packages?

Thanks in advance.
