Qt ported to PRS-505

[bero]

Hi,
I've just ported the Qt toolkit to the PRS-505 -- including automatic screen updates etc.
This should make it fairly easy to run quite a few native applications (even QtWebKit works, so displaying html isn't a problem).

The source can be found in our branch of the Qt git repository:

git clone git://gitorious.org/~blankpage/qt/blankpage-patches.git qt-prs505
cd qt-prs505
git checkout eink

You'll still need a normal ARM crosscompiler (building it with crosstool is probably the easiest way to get one).

The dynamic loader on the PRS505 seems to be somewhat buggy, linking statically is recommended. Tested Qt configuration is

./configure -embedded arm -no-glib -no-script -no-stl -no-exceptions -no-xmlpatterns -no-qt3support -opensource -confirm-license -no-nis -no-iconv -no-cups -qt-freetype -qt-libpng -qt-gif -qt-libjpeg -webkit -no-phonon -no-phonon-backend -static -release

Enjoy...

Doesn't webkit in qt 4.6 require xmlpatterns?

It doesn't - but having xmlpatterns enabled adds some functionality to webkit (XSLT support).

For what I need, this functionality isn't required but bloats qt and webkit (xmlpatterns requires exceptions too) - so I decided to disable it in my build.

That said, I don't see anything that would break if xmlpatterns and exceptions were enabled, I'd expect that config to just work.

Great news!
Do you have a sample/test app to play with? Pretty little hello world, maybe?

Any of the normal Qt demos will do, given I didn't touch the Qt API.

The code I actually used for initial testing comes down to

#include <QApplication>
#include <QLabel>
#include <QTimer>

int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QLabel l("test", 0);
    l.showFullscreen();
    QTimer::singleShot(10000, &app, SLOT(quit()));
    app.exec();
}

After getting that to run, I moved on to simply compiling a few standard applications/applications I was using on my desktop box.

I'm attaching some code I've written to talk to the keyboard, that makes it actually usable beyond running automated demos. When I have a bit of time I'll turn it into a proper Qt keyboard driver...

Wondering if you've stopped working on this... :S
