Unfortunately It didn't do the trick.... I can't tell any difference ...still crashes with the QPainter::save().... <br><br>Please let me know if any of you have any more ideas... I will play a little more tomorrow.<br>

<div>That’s not how it’s done.</div>
<div> </div>
<div>1. In your .pro file, add:</div>
<div>QT += opengl</div>
<div> </div>
<div>2. at the top of your cpp, add:</div>
<div>#include <QGLWidget></div>
<div> </div>
<div>3. when you initialize your QDeclarativeView:</div>
<div>QGLWidget glWidget;</div>
<div>QDeclarativeView view;</div>
<div>view.setViewport(&glWidget);</div>

<div>> Why not install Qt debug symbols on the device and run/attach to
your<br>> program there under gdb?<br>><br>><br>><br>>

Относно: N950 SEGFAULT - help?<br>> До: <a href="mailto:maemo-developers@maemo.org" target="_blank">maemo-developers@maemo.org</a><br>> Изпратено на: Петък,
2011, Октомври 7 05:20:55 EEST<br>> I hit a wall with my application so
I am looking for someone to help<br>> everywhere I can.<br>><br>>
The short version: how can I get qt creator to debug my application on
the<br>> device. Right now I get CRC mismatch warnings for all
libraries and I assume<br>> this is what prevents me to see any trace
information<br>><br>> That is what I get when I start to
debug:<br>> ...<br>> the debug information found in<br>>
"c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvrPVR2D_DRI2WSEGL_r125.so"<br>>
does not match<br>>
"c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvrPVR2D_DRI2WSEGL.so"<br>>
(CRC mismatch).<br>><br>> the debug information found in<br>>
"c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvr2d_r125.so"<br>>
does not match<br>>
"c:/qtsdk/madde/sysroots/harmattan-nokia-meego-arm-sysroot-1134-slim/usr/lib/libpvr2d.so"<br>>
(CRC mismatch).<br>><br>> ...<br>><br>> I assume I need to
install "debug symbols/versions" for the qt libraries on<br>> the
device somehow. Am I right? How can I accomplish this?<br>><br>> The
long version:<br>><br>> My applications uses qml\webview and
everything works fine until I swipe out<br>> of my application and then
later come back to it. With one click or two I<br>> get a segfault.
This is all the information that I managed to get running<br>> gdb on
the device:<br>><br>> (gdb) backtrace<br>> #0 0x42068924 in
QPainter::save() () from /usr/lib/libQtGui.so.4<br>> #1

0x48ec294c in ?? () from /usr/lib/libQtWebKit.so.4<br>><br>> Program

suggestions?<br>><br>> Thanks in advance,<br>>
