ZDOCK -- libg2c.so.0: cannot open shared object file-优快云博客

本文链接：https://blog.youkuaiyun.com/li1guangjun/article/details/120825954

在CentOS7上运行ZDOCK时遇到缺少libg2c.so.0的错误。通过执行`yum install compat-libf2c-34`安装兼容库后，问题得到解决，成功安装了/usr/lib64/libg2c.so.0，重启服务器后ZDOCK可以正常运行。

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：

[root@localhost ~]# yum install compat-libf2c-34
