Not sure how to quote in Gmail sadly... Never heard of IPlinux. Currently we're using, or at least trying to use Qt Embedded in Qt Creator and OpenEmbedded.

I'll have to look at the Qtopia core guide at home. For some reason always times out with some tcp_error at the office. :/

As for the platform and errors, we're running Overo Earth as the target device and RHEL 5 on the development side. The first error was the following related to freetype (there may have been more error text, but I can't recall it.

Nokia provided a fix due to a compiler error in GCC 3.4:

To fix this issue patch /src/3rdparty/freetype/include/freetype/config/ftconfig.h Line 330.

"orr %0, %2, lsl #16\n\t" /* %0 |= %2 << 16 */

+ "orr %0, %0, %2, lsl #16\n\t" /* %0 |= %2 << 16 */

Another error we were seeing related to JavaScriptCore/wtf/Platform.h, I believe around line 680 or so. I didn't save the compiler output and would have to attempt to recreate it. It appears to have gone away since I ran ./configure again with -no-webkit and -no-javascript-jit.

It just seems the more errors we get fixed, the more come up. I wouldn't expect Nokia's Qt Embedded code to have errors like this, which leads me to believe we may simply be configuring it incorrectly with the configure script on the development workstation.

./configure -embedded arm -no-webkit -no-javascript-jit
<...compilerer errors...>

I'm experimenting with Qt on the Overo Fire, building it using the IPlinux

There's a guide here which may help:

Can you post the errors here? Can you say what platform you are running on?

It may also be worth sending questions to the qt-embedded-interest mailing

Technically speaking, it may be possible. From a licensing point of view, I
don't know if either the Qt Commercial or OpenEmbedded licenses impose any
kind of restrictions that prohibit using one to build the other.
