    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>
    Regards,<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>

          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;

            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>
