1, 我已经装好了LAPACK。define the environment variable LRTPATH pointing to the folder where the files will be installed:

gedit ~/.bashrc

在export那加一行：export LRTPATH=/media/Expansion/template/ASSEF/lrt_v2/

保存退出

2, 安装g77。我没试直接装行不行。只是按照网页这样装：

    a)sudogedit /etc/apt/sources.list

 b)Then to the bottom of that file add:

 c)sudo apt-get update

   d)test it try compiling a `Hello World!’ program 

    gedit hello.f& 输入：

         program hello

   e)g77 -o hello hello.f

 f)./hello

 g)如果报缺失文件则，

  sudo cp /usr/lib/gcc/x86_64-linux-gnu/4.6.3/libgcc_s.so /lib/libgcc_s.so.1

 h)注释掉那四行sudo gedit /etc/apt/sources.list
