(因为需要qt-3.3作支持，所以需要先安libqt3-mt,libqt3-mt-dev,下载qt-devel-3.3.8-4.fc7.i386.rpm,然后用alien转为deb,再用dpkg -i --force-overwrite 来安装此包)
sudo apt-get install libqt3-mt
sudo apt-get install libqt3-mt-dev
sudo apt-get install alien
sudo alien qt-devel-3.3.8-4.fc7.i386.rpm
dpkg -i --force-overwrite qt-devel-3.3.8-4.fc7.i386.deb
(开始安qvfb)
cd qvfb2-2.0
./configure --with-qt-includes=/usr/lib/qt-3.3/include --with-qt-libraries=/usr/lib/qt-3.3/lib --with-qt-dir=/usr/lib/qt-3.3
sudo make
sudo make install
(qvfb2与1不同，没有文件输入是不会显示出框图的)
