On the road to Qt 5: Qt 5 base, tools, jsbackend and xmlpatterns in experimental

The first Qt 5 packages have been accepted in Debian experimental.

What's there

To start building Qt 5 apps you will need to export QT_SELECT=qt5, install the package qt5-defaults or read qtchooser's man page. Note that exporting QT_SELECT has precedence over installing qt5-defaults.

What's not there


AMD64 is already there because it's the arch used by maintainers to build the packages. i386 should be following as soon as buildds catch up. Most surely ARM-based archs will be there at some point too.

Other archs will need some love. Not strange, the Qt project supports amd64, i386 and ARM, but we Debian have normally prepared patches to make it build in other archs. And yes, we try to push them upstream for everyone's benefit. So, if you are missing it in your arch, take a look. You may be the one who enables Qt 5 in it :-)

GLES2 and Wayland

We don't have GLES2 or Wayland support yet. Building it will most probably break the desktop for people using proprietary video drivers (or at least I was told so). I'll surely provide non-official packages with GLES2/Wayland enabled to allow people testing it, but not soon.

This also means that we are not currently able to split X11 and framebuffer support. But we have time to work on it :-)

Non DFSGs compliant files

If you get the original source code tarball from Debian you will notice that it has dfsg in it's name. That means that we had to remove some non DFSG compliant stuff from the original tarball, namely:

  • Every RFC.
  • Three files used for testing the build, which are made of RFCs.
  • Some fonts.

What's following

Other parts of Qt 5 are on the way. And remember, this packages would not have been possible if it weren't for the great Debian's pkg-kde team. My kudos to them.

On the road to Qt 5: Qt 4.8.4 and qtchooser uploaded to experimental

I have just uploaded Qt 4.8.4 to experimental. Apart from being the newest upstream release of the 4 series, it adds the basic support for coexisting with Qt 5. Because of this support it will need to go trough the NEW queue though, so we will need to be patient.

Developers will be interested in qtchooser, the tool that allows to switch between Qt 4 and 5 development apps. It has also been uploaded to experimental.

Of course, all this has been possible thanks to the efforts of the wonderful Qt/KDE team =)

Update: our efficacious FTP masters have already made Qt pass the NEW queue. Thanks a lot!
