I am trying to use KDE3.4 with CYGWIN.by following the README I found under webdev.cegit.de/snapshots/kde-cygwin/kde/kde3.4. I try to rebase all dll's by using the command you give : rebase -b ... and I obtain : rebaseall: only ash processes are allowed during rebasing. and then I don't know what to do !!! Can you help me ? Thanks a lot! Roger
