在Centos7上运行ZDOCK，遇到报错：
[user@localhost zdock3.0_XL_linux_64bit]$ ./mark_sur P37108_u.pdb.ms new.pdb ./mark_sur: error while loading shared libraries: libg2c.so.0: cannot open shared object file: No such file or directory
查找 /usr/lib 、/usr/lib64目录下没有libg2c.so.0文件，在网上查找相关的解决方法：
QOCA软件安装（附安装后出现缺少libg2c.so.0报错的解决办法）
ubuntu报错：libg2c.so.0:cannot open shared object file: no such file or directory/wrong ELF class（已解决）
解决办法都是在Ubuntu系统下，但是自己的系统是centos7，后面
找到libf2c，点击下载或者直接在服务器运行命令：

装上/usr/lib64/libg2c.so.0，重启服务器就可以用ZDOCK
