<h2>Build Issues</h2>
<h4>Static libraries on Mac OS X</h4>
<p class="issue">Building a static build on mac will fail the first time.</p>
<p class="workaround">Run qmake a second time.</p>
<h4>QTDIR</h4>
<p class="issue">Some applications(e.g. uic3) need QTDIR set and QTDIR/bin in the path to work.</p>
<p class="workaround">Set QTDIR and PATH as described in INSTALL.</p>
<h4>ODBC driver on Windows</h4>
<p class="issue">Problems compiling the ODBC driver.</p>
<p class="workaround">Change the include from qapplication.h to qcoreapplication.h</p>
<h4>QtGui does not link because of accessibility errors</h4>
<p class="issue">undefined reference to QAccessible::setRootObject(QObject*)</p>
<p class="workaround">Rerun configure and rebuild, if that does not help, add the contents of $QTDIR/.qt.config to $QTDIR/.qmake.cache</p>
<!-- General section ---------------------------------------------- -->
<a name="general"></a>
<h2>General</h2>
<h4>No connection to Oracle</h4>
<p class="issue">I cannot connect to my Oracle server</p>
<p class="workaround">Use the Oracle >= 9 client libraries, currently there is no workaround for OCI 8</p>
<h4>QSqlModel</h4>
<p class="issue">Only the first 16 rows from a database result are displayed</p>
<p class="workaround">You are using a database driver which does not report back the size of a result set and incremental fetching is not yet implemented in the itemviews. You can either use another database like MySQL or increase the QSQL_PREFETCH in qsqlmodel.cpp</p>

<h4>GDI handle leak</h4>
<p class="issue">Setting fonts through QPainter::setFont() leaks GDI
handles on windows. This is for instance visible in the OpenGL
part of the Arthur demo. The issue will be fixed before the next
preview.</p>
