Somebody has deleted these instructions. Please accept our apologies. The entry below is a temporary measure but should get you up and running:
某人己经删掉了这些使用说明。请接受我们的道歉。下面的输入是暂时性的方法但可以使你进行的很顺利：
(i) Download the linux binary from 32/64bit accroding to
requirements.
1、下载linux二进制文件，从这里根据要求下载32/64位。
(ii) cd to the directory where you wish to install gfortran; let us say $mypath, which might conveniently be /home or /home/myname or /etc (or even /).
2、cd（译者注：Linux命令更改目录）到你希望安装gfortran的目录去，我们假设是 $mypath，这个通常可能是 /home 或者 /home/myname 或者 /etc(甚至是根目录/).
(iii) tar -zxvf $path_to_download/gfortran-linux.tar.gz (if the file you downloaded ends with .tar.gz) or tar -jxvf $path_to_download/gfortran-linux.tar.bz2 (if the file ends with .tar.bz2)
3、tar –zxvf $path_to_download/gfortran-linux.tar.gz(假如你下载的文件以.tar.gz结尾)或者 tar –jxvf $path_to_download/gfortran-linux.tar.bz2(假如文件以.tar.bz2结尾)。（译者注：path_to_download 是你下载文件的目录）
(iv) The previous step has created a directory irun, under $mypath that contains gfortran-4.2 and gcc-4.2 plus associated libraries. This will not interfere with any other compiler.
4、之前的步骤产生了一个irun目录，在$mypath下包含着gfortran-4.2和gcc-4.2关联库。这不会和任何其他编译器冲突。
(v) $mypath/irun/bin/gfortran --version will tests that all is well. You should see GNU Fortran 95 (GCC) 4.2.0 20060602 (experimental) Copyright (C) 2006 Free Software Foundation, Inc.

5、$mypath/irun/bin/gfortran –version 将会检测所有是否正常。你应该看到GNU Fortran 95(GCC)4.2.0 20060602(experimental)Copyright(C)2006 Free Software Foundation,Inc.

(vi) I have to confess that on my solo user system, I use $mypath "", so that the invocation is /irun/bin/gfortran You might find it cleaner to use /etc
6、我必须坦言在我的但用户系统中，我用$mypath””,所以调用是 /irun/bin/gfortran 。你会发现用/etc很清楚。
(vii) You will need to set LD_LIBRARY_FLAG or compile with -static.
7、你需要设置 LD_LIBRARY_FLAG 或者编译用 –static
(viii) Assuming that you are using bash, find your .bash_profile and add the line,
export LD_LIBRARY_PATH$mypath/irun/lib alternatively, invoke bash at the command line and enter this previous line.
You should have an operational gfortran by now.
8、加入你使用bash,找到.bash_profile 并加入一行，export LD_LIBRARY_PATH$mypath/irun/lib
或者在命令行下调用bash，输入之前的那一行。
到此为止，你有了一个可以运行的gfortran了。
