This file describes some things to be aware of when building PyQt under Linux. Broken Mandrake and Debian Qt Installations Both Mandrake and Debian implement some or all of the style classes, particularly QSGIStyle, QCDEStyle, QWindowsStyle and QMotifStyle, as plugins 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.
