Latest Qt and Qt mobility evaluation on Maemo
Regardless of the Qt and Qt Mobility versions provided by the Maemo5 firmware, an evaluation build of the latest Qt and Qt Mobility is available from the Extras-devel repository. These libraries cannot be used for publishing software to Ovi (or promoted to Extras) nor do they come with any warranty, but are good for evaluating real-life performance and behavior. The components that are part of this initiative are labeled with experimental in their package names. They are installed in parallel to the Maemo5 libraries, so they pose minimal danger to your existing install and do not affect stable software written for Maemo.
Qt Mobility 1.1.0
To install, from the console (both on device and in scratchbox) do
apt-get install libqtm-11-dev
For Qt to know which mobility version to use, you will need to specify the following
CONFIG += mobility11
in your projects .pro file (instead of CONFIG += mobility). For help and discussion about this version, see the maemo.org community developer thread
Qt Mobility 1.2.0 tech preview
Currently work in progress, will be used in the same way as libqtm-11, so
apt-get install libqtm-12-dev
and in you .pro file:
CONFIG += mobility12
Qt 4.8
libqt4-experimental
apt-get install libqt4-experimental-dev
To use this version, you have to either call its qmake with
/opt/qt48/bin/qmake my-project.pro
or, if you are using the Nokia Qt SDK, add it as a alternate Qt version
NOTE: Qt 4.8 will receive it's first public binary release when it reaches at least the Tech Preview phase (until then the APIs are changing too quickly for public releases to make sense)
