Hello again Lorenzo. I haven't tried configuring and building my Qt project using Cygwin under Windows. Rather, I have only configured and built it under Linux Fedora Core 2 and using the default Qt installation (version 3.3) that is distributed with it. If I invoke the following switch ; --with-Qt-dir when I run the configure script, then my project successfully configures and compiles. This has always worked for me, so I haven't bothered to try using any of the other Qt related configure script switches, i.e. --with-Qt-lib-dir, etc. You could maybe try using this approach, and if you find that it doesn't work for you then you could perhaps send an e-mail to the author of the bnv_have_qt macro. I don't use Windows for software development, so I'm not sure what you would need to do in order to get the bnv_have_qt macro to find your Qt installation using just this one configure script switch. Sorry I can't be of more any more help. Good luck with it. - Craig Sanders
