Just for the sake of completeness...

I find the following problem with Cygwin-X QT4 4.7.4.

Trying to build a CERN application, ROOT [*], it fails in this way:

[...]

To reproduce:

$ wget ftp://root.cern.ch/root/root_v5.32.01.source.tar.gz
$ tar -xf root_v5.32.01.source.tar.gz
$ cd root

$ ./configure win32gcc --enable-qt --with-qt-incdir=/usr/include/qt4 
--with-qt-libdir=/usr/lib/qt4/lib 2>&1 | tee /tmp/build-ROOT.log

$ make 2>&1 | tee -a /tmp/build-ROOT.log

ROOT builds fine with QT4 4.5 on Cygwin and on GNU/Linux Kubuntu with 
QT4 4.7.4.

Another strange thing I notice is that I need to add

   --with-qt-incdir=/usr/include/qt4 --with-qt-libdir=/usr/lib/qt4/lib

to "./configure..."

Ciao,
Angelo.
