NCARG安装配置出现error while loading shared libraries: libg2c.so.0问题额解决办法

ncl
ncl: error while loading shared libraries: libg2c.so.0: cannot open shared object file: No such file or directory

1.yum -y install libg2c.so.0安装之后

2.which libg2c.so.0 得到其安装的路径 /usr/lib

3. 在/etc/bashrc中加入.设置环境变量 export
LD_LIBRARY_PATH=/usr/lib/:$LD_LIBRARY_PATH环境变量

4.到libg2c.so.0 安装的路径 /usr/lib 中

cp libg2c.so.0 /lib64 中

解决这个问题查询的资料

先看看运行机器上面有没有这个动态链接库，有的话再看看环境变量对不对，libg2c.so.0 所在路径是不是在你的LD_LIBRARY_PATH里面了，可以到/etc/ld.so.conf文件里面去更改，然后ldconfig

如果有的话，按2楼操作，一般情况下是动态文件没有，也就是缺少一些文件包，不知道你用的是什么系统，如果是Fedora（CentOS, REDHAT_AS）之类的可以用

yum -y install libg2c.so.0试试，如果是Ubuntu的话，好像是ape-get之类的。如果还不行的话，就到网上下一个rpm包。不过有时候包的依赖性很难解决。

安装成功之后，which libg2c.so.0查询安装的路径

把libg2c.so.0文件复制到根目录下/lib试试，重新登陆试试

查询安装的软件还是要用rpm命令。
rpm -qa 查询所有安装的rpm包，可以配合grep命令。
rpm -qi 查询某个具体包的介绍。
rpm -ql 列出某个具体包的所有文件。
