[Marble-devel] Using Marble library with Qt Embedded

[Jeremie Scheer]

Any idea ?

Is it simply possible to use Marble in a Qt Virtual Framebuffer with Qt 
Embedded ?

I think it should be, because I found this link on the Internet 
http://wm161.net/2008/07/26/marble-under-qtembedded-linux/ . A little 
bit old but it shows that Marble could run under Qt Embedded.

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...

My Qt Embedded is configured like this:

    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


And I configure Marble to build against Qt like this:

    PATH=/usr/local/Trolltech/QtEmbedded-4.7.2/bin:$PATH cmake
    -DQTONLY=ON ../marble_qvfb/
