It seems no libqt-mt.so is available with qt4, don't ask me why. $ ls -la /usr/qt/3/lib/ total 4 drwxr-xr-x 2 root root 4096 Mar 7 16:46 . drwxr-xr-x 6 root root 59 Mar 7 16:46 .. lrwxrwxrwx 1 root root 13 Oct 13 15:50 libqt-mt.so -> libqt-mt.so.3 lrwxrwxrwx 1 root root 15 Oct 13 15:50 libqt-mt.so.3 -> libqt-mt.so.3.3 lrwxrwxrwx 1 root root 17 Oct 13 15:50 libqt-mt.so.3.3 -> libqt-mt.so.3.3.4 lrwxrwxrwx 1 root root 11 Oct 13 15:50 libqt.so -> libqt-mt.so lrwxrwxrwx 1 root root 13 Oct 13 15:50 libqt.so.3 -> libqt-mt.so.3 lrwxrwxrwx 1 root root 15 Oct 13 15:50 libqt.so.3.3 -> libqt-mt.so.3.3 lrwxrwxrwx 1 root root 17 Oct 13 15:50 libqt.so.3.3.4 -> libqt-mt.so.3.3.4 lrwxrwxrwx 1 root root 11 Oct 13 15:50 libqui.so -> libqui.so.1 lrwxrwxrwx 1 root root 13 Oct 13 15:50 libqui.so.1 -> libqui.so.1.0 lrwxrwxrwx 1 root root 15 Oct 13 15:50 libqui.so.1.0 -> libqui.so.1.0.0 $ c$ ls -la /usr/qt/3/plugins/designer/libqscintillaplugin.so -rwxr-xr-x 1 root root 13732 Dec 12 18:10 /usr/qt/3/plugins/designer/libqscintillaplugin.so $ I wonder why revdep-rebuild has never found that as a problem. I have qscintilla library left under the /usr/qt/3/ path. It seem qscintilla depends on qt3 but then why the upgrade to qt4 wasn't blocked by qscintilla? Maybe bug #121069, comment #3 is a similar problem. So, I unmerge qscintilla and did "rm -rf /usr/qt/3" to remove the empty directories.
