My git head is ca2b65a6515800991dae49d1815b7bb933f4015c.
Compile qt including webkit with external toolchain (codesourcery
default from selection).
Use simple qt code to test webkit:
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QWebView *view = new QWebView();
view->load(QUrl("http://mrdoob.com/projects/chromeexperiments/ball_pool/"));
view->showFullScreen();
return a.exec();
}
After app. starting it failed with Illegal instruction (don't check deeply).
Do same with buildroot builded toolchain (default selection just add
WCHAR and C++ support to be able compile QT).
Application work fine without problem.

Haven't tested webkit, but this is probably the same issue I've been finding
in lots of other packages. CodeSourcery is a multilib toolchain, and it
picks its library based on the machine architecture flag (-march). It
assumes armv5te by default, so it is critical when you are targeting one of
the other libraries like armv4t or armv7-a (thumb) to provide -march to the
package. This is part of the $(TARGET_CFLAGS) variable, but some packages
don't pass it properly.

Yes, quite likely.
Marek, could you give us some details about your hardware configuration
(which CPU type) and Buildroot configuration ?
Thanks,
Thomas

ARCH=arm920t and just select qt including webkit + select external toolchain.

What does that mean ? Does that mean that your processor is an ARM920T
*and* that you selected this CPU type in Buildroot ?

Sorry have it setup on my laptop @ work.
Yes CPU type is ARM920T (mini2440) and of course is selected.
I can post .config tomorrow at morning.
