I started looking into it yesterday but Qt Embedded wasn't compiling
on my system due to some known bug where glib and webkit interfere.<br>
<br>
I'd suggest trying to move all marble plugins away first (just
remove them from lib/marble/plugins in the installation directory of
marble) and see if that changes things. Might be some threading
issue, the parser plugins working on startup for example run in
their own thread each.<br>

Any idea ?<br>
<br>
Is it simply possible to use Marble in a Qt Virtual Framebuffer
with Qt Embedded ?<br>
<br>
I think it should be, because I found this link on the Internet <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://wm161.net/2008/07/26/marble-under-qtembedded-linux/">http://wm161.net/2008/07/26/marble-under-qtembedded-linux/</a>
. A little bit old but it shows that Marble could run under Qt
Embedded.<br>
<br>
I can't see what is the origin of the bug because I've no QThread
or QMutex in my application. It can only come from the compilation
of Marble...<br>
<br>
My Qt Embedded is configured like this:<br>
<blockquote><small>configure -embedded x86_64 -no-cups -no-nis
-depths 16,18 -qvfb -prefix
/usr/local/Trolltech/QtEmbedded-4.7.2 -glib -confirm-license
-qt-sql-sqlite<br>
</small></blockquote>
<br>
And I configure Marble to build against Qt like this:<br>
<blockquote><small>PATH=/usr/local/Trolltech/QtEmbedded-4.7.2/bin:$PATH
cmake -DQTONLY=ON ../marble_qvfb/</small><br>
</blockquote>

Hi,<br>
<br>
I'm currently trying to use a Marble library built against <u>Qt
4.7.4 Embedded x86</u>.<br>
<br>
My application using Marble is built against the same Qt and is
running in a Qt Virtual Framebuffer with a QWS Server.<br>
<br>
In the Qt project file, I simply added : <i>LIBS =
-lmarblewidget</i> to link with Marble. And when running the
application, I defined the environment variable <i>LD_LIBRARY_PATH=/usr/local/lib</i>
where Marble libraries are installed.<br>
<br>
The problem is : when I run the application, before any
instruction can be executed, it crashes on :
<meta name="qrichtext" content="1">
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;"><!--StartFragment--><span
style=" font-family:'Monospace'; font-size:9pt;
color:#be1414;">QMutex::lock: Deadlock detected in thread

<meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1">
<style type="text/css">
p, li { white-space: pre-wrap; }
</style><br>
Here is my application code :<br>
<blockquote><small>#include <QtGui/QApplication><br>
#include <marble/MarbleWidget.h><br>
#include <marble/MarbleModel.h><br>
#include <marble/global.h><br>
#include <QWSServer><br>
<br>
using namespace Marble;<br>
<br>
int main(int argc, char** argv)<br>
{<br>
QApplication app(argc,argv);<br>
QWSServer *sw = QWSServer::instance ();<br>
<br>
// Create a Marble QWidget without a parent<br>
MarbleWidget *mapWidget = new MarbleWidget();<br>
<br>
// Load the OpenStreetMap map<br>
mapWidget->setMapThemeId("earth/openstreetmap/openstreetmap.dgml");<br>
mapWidget->setProjection(Mercator);<br>
<br>
mapWidget->show();<br>
<br>
return app.exec();<br>
}</small><br>
</blockquote>
<br>
If I build the same application (without the QWS Server) and
Marble against Qt x86, it works well.<br>
<br>
Is there anything I did wrong with Qt Embedded ?<br>
<br>
Thanks,<br>
