Why build halted when creating makefiles ...

[Richard Meng]

 Hi all
 
 When i built Qt in Cygwin with the command:
 
 echo yes | ./configure -platform cygwin-g++ -plugin-imgfmt-mng -qt-zlib -qt-gif -qt-libpng \
  -qt-libjpeg -qt-libmng -no-g++-exceptions -thread -no-stl -no-sm -no-xft -no-xkb -no-xrender \
  -disable-opengl -disable-sql -prefix /opt/qt/3.3 -fast
 
 But it halted when "Creating makefiles ... "
 the screen is like this:
 -------------------------------------------------------------
 | ...
 | Finding project files. Please wait ...
 |     245 projects found.
 |
 | Creaing makefiles. Please wait ...
 |   For /src/qt-3/src/moc/moc.pro
 -------------------------------------------------------------
the it is halted with 100% cpu usage.

What's wrong with it ??
 
 Best regards,
