If you can live with QT3, just go to kde-cygwin.sourceforge.net and install the pre-packaged version using 'setup.exe'. > Should I also to call QT gmake with "-unix -o" to generate Makefile, > the same parameters I was calling from linux?

In general, if you work the way that you would work on a Linux system, then you'll have better luck with Cygwin. -- Larry Hall http://www.rfk.com RFK Partners, Inc.
