<title>Debugging GNOME Programs With DRD</title>
<para>
GNOME applications use the threading primitives provided by the
<computeroutput>glib</computeroutput> library. This library is built
on top of POSIX threads, and is hence directly supported by DRD.

<title>Debugging Qt Programs With DRD</title>
<para>
The Qt library is the GUI library used by the KDE project. Currently
there are two versions of the Qt library in use: Qt3 by KDE 3 and Qt4
by KDE 4. If possible, use Qt4 instead of Qt3. Qt3 is no longer
supported, and there are known problems with multithreading support in
Qt3. As an example, using QString objects in more than one thread will
trigger race reports (this has been confirmed by Trolltech -- see also
Trolltech task <ulink
url="http://trolltech.com/developer/task-tracker/index_html?id=206152&amp;method=entry">#206152</ulink>).
</para>
<para>
Qt4 applications are supported by DRD, but only if the
<literal>libqt4-debuginfo</literal> package has been installed. Some
of the synchronization and threading primitives in Qt4 bypass the
POSIX threads library, and DRD can only intercept these if symbol
information for the Qt4 library is available. DRD won't tell you if it
has not been able to load the Qt4 debug information, but a huge number
of data races will be reported on data protected via
<literal>QMutex</literal> objects.
