需要安装Qt libraries 4.4.0以上，这里下载4.7.4版本，4.8的可能会因为dbus版本过低而报错

cutycapt还需要x server的支持，如果没有，可以使用xvfb-run代替

wget http://www.flexthinker.com/wp-content/uploads/2009/11/xvfb-run.sh.txt
mv ./xvfb-run.sh.txt /usr/local/CutyCapt/xvfb-run.sh
chmod u+x /usr/local/CutyCapt/xvfb-run.sh

如果中文乱码安装中文包
yum install fonts-chinese

./xvfb-run.sh --server-args="-screen 0, 1024x768x24" ./CutyCapt --url=http://www.17drupal.com --out=/tmp/a.png

常见错误：

1. 如果报错 ：Cannot resolve 'dbus_get_version' in your libdbus-1.
解决办法：升级dbus或者使用低版本qt(qt4.8依赖 dbus-1.2 以上, qt4.7.4依赖 dbus-1.0.2以上)
wget http://dbus.freedesktop.org/releases/dbus/dbus-1.6.4.tar.gz
tar -xzf dbus-1.6.4.tar.gz
./configure
make && make install

2. 报错：make: Nothing to be done for `first'. Basic XLib functionality test failed!

解决办法：yum -y install libX11-devel libXext-devel libXtst-devel

3. 报错：g++: Internal error: Killed (program cc1plus)

解决办法：内存不足， 在linux下增加临时swap空间

step 1:
　　#dd if=/dev/zero of=/home/swap bs=1024 count=500000
　　注释：of=/home/swap,放置swap的空间; count的大小就是增加的swap空间的大小，1024就是块大小，这里是1K，所以总共空间就是bs*count=500M
 
step 2:
　　# mkswap /home/swap
　　注释：把刚才空间格式化成swap各式
 
step 3:
　　#swapon /home/swap
　　注释：使刚才创建的swap空间

如果想关闭刚开辟的swap空间，只需命令：#swapoff

4. 报错: cannot find -lXrender

解决办法：yum install libXrender
ln -s /usr/lib64/libXrender.so.1.3.0 /usr/lib64/libXrender.so

5.报错：cannot connect to X server :99

解决办法：yum install Xvfb
