This file describes some things to be aware of when building PyQt under Linux.


Broken Mandrake and Debian Qt Installations

Both Mandrake and Debian omit some of the style classes, particularly
QSGIStyle, QCDEStyle, QWindowsStyle and QMotifStyle, but don't make the
corresponding changes to the file $QTDIR/include/qconfig.h.

If you get unresolved symbols relating to any of these classes when building
PyQt then trying adding one or more of the following lines to
$QTDIR/include/qconfig.h and then re-building PyQt.

#define	QT_NO_STYLE_CDE
#define	QT_NO_STYLE_MOTIF
#define	QT_NO_STYLE_SGI
#define	QT_NO_STYLE_WINDOWS

Thanks to John R Marshall and James Lamanna.
