Qt4/Cygwin link errors building from Hello.cpp

[metaed]

I am trying for the first time to build a Qt program using Qt4 from the Cygwin distribution. The recipe I'm following is the Hello program on the Wikipedia page for Qt.

To install Qt, I selected the available Qt4 components in the Cygwin installer. I am appending the output of cygcheck -c which shows the packages that are active in my Cygwin installation. Due to a 6,000 character limit posting here, I am only able to offer filtered output, which is probably less than helpful.

The build fails in the link stage:

@
$ mkdir Hello
$ cd Hello
$ cat > Hello.cpp
#include <QtGui>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QLabel label("Hello, world!");
label.show();
return app.exec();
}
$ qmake-qt4 -project
$ qmake-qt4 Hello.pro
$ make
g++-4 -o Hello.exe Hello.o -L/usr/lib/qt4/lib -lQtGui -L/usr/lib/qt4/lib -laudio -lXt -lpng -lSM -lICE -lXi -lXrender -lXrandr -lXfixes -lXcursor -lXinerama -lfontconfig -lexpat -lfreetype -lXext -lX11 -lQtCore -lz -lm -lgthread-2.0 -lglib-2.0 -lintl -liconv -ldl -lpthread

Before I spend a potentially long, long time digging into this, I wondered if this was a well known problem with an easy solution.

Cheers,
