Hi,<br>
<br>
can you try whether using the plain.dgml theme (<small>"earth/plain/plain.dgml"</small>)
instead of openstreetmap.dgml helps? This map theme does not have
any texture layers. The texture layers make use of threads as well.<br>
<br>

Hi,<br>
<br>
Thank you for your answer.<br>
<br>
Unfortunately it doesn't seem to be the plugins that cause the
thread issue.<br>
I tried what you suggested me to do but I always run into the same
error with QMutex.<br>
<br>
It is the same error that makes my application crash in a Qt
Virtual Framebuffer or on ARM platform.<br>
<br>

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 0x7f1fe30bb740 </span><!--EndFragment--></p>
<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>
