As Darrell pointed out, there are multiple declarations of 'TQListViewItemIterator it( d->listView )' in kipi-plugins/flickrexport/imageslist.cpp that are now both seen by gcc 4.7. Could one of the c/c++ gurus take a look at suggest how to make sure this is only seen once? Thanks. -- David C. Rankin, J.D.,P.E.
