真的没有这个文件  我还是新建的 是空文件  但是他说是只读文件 不让写东西进去

chmod 777 50-unity-greeter.conf

按理说重新链接后不会有问题呀。

那你安装grib2之前，有没有用新立德更新过：

问题解决了
首先我一开始没有进root，虽然没权限的时候加了sudo，但可能还是有问题，具体也不太清楚
另外重装了netcdf-c和netcdf-fortran，再按楼主方法安装wgrib2，
在make结束有提示zlib.h无法连接，虽然我之前装了zlib。后来用了两条命令解决：
       apt-get install zlib1g
       apt-get install zlib1g.dev

厉害！希望一起学习进步!

如果只按照以上步骤安装gfortran，会导致在安装wgrib2时候无法识别编译器gfortran，所以要对编译器进行重新链接：
【重新链接gcc，g++，gfortran】

1.建立备份文件夹：
mkdir /usr/bin/gccbackup
mkdir /usr/bin/g++backup
mkdir /usr/bin/gfortranbackup

2.先将原来的链接改名，终端输入：
mv /usr/bin/gcc /usr/bin/gccbackup
（g++，gfortran一样移动到各自备份文件夹）
3.重新链接（注意空格）
ln -s /usr/bin/gcc-6 /usr/bin/gcc
ln -s /usr/bin/gfortran-6 /usr/bin/gfortran
ln-s/usr/bin/g++-6 /usr/bin/g++
4.检查版本信息，终端分别输入：
gcc --version （回车）
gfortran --version （回车）
g++ --version （回车）
如果都是显示6.3.0版本，那么软件的兼容性已经处理完毕！下面安装wgrib2就不会识别不了编译器了！
=============================================
照做了，没做之前还能看到Gfortran的版本，做了之后查不到gfortran了，说没安装！！
怎么回事啊现在回不去了。。

gfortran重新安装，然后再重新编译看看行不行

如果不是6.3.0版本，比较低，还要不要这样做？
已经重装了N次还是不行

要的，gcc，g++，gfortran版本要一致。然后重新编译

export CPPFLAGS=-I/usr/local/NETCDF/include
export LDFLAGS=-L/usr/local/NETCDF/lib
以上两句是用来解决：
错误：error: netcdf.h could not be found. Please set CPPFLAGS.
报错问题。
=================
加了这2句还是报错

蟹蟹楼主，安装快要完成
