我有一个需要g77编译器的库。
我在网上发现了一些方法;但每次失败。以下是我的两项努力的总结：
1）我下载了包，解压它 $ sudo ./install.sh

2）我按照（http://seanelvidge.com/2012/08/install-g77-on-ubuntu-9-04/#comment-549085）中的描述更改了sources.list文件，然后在“sudo apt-get update”运行正常后找不到g77。
$ sudo apt-get install g77
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package g77 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
一些帮助将不胜感激。

我做了以下事情： 1）从这里下载64位的g77 http://www.ziddu.com/download/16792814/g77_x64_debian_and_ubuntu.tar.gz.html
2）然后做了以下事情：
tar -xzvf g77_x64_debian_and_ubuntu.tar.gz
cd g77_x64_debian_and_ubuntu
chmod +x ./install.sh
./install.sh

OP链接到我的博客文章，用于安装不再有效的g77。但是我written a new one for versions of Ubuntu >=14.04
有关详细信息，请参阅我的链接，但基本概述是：
添加Ubuntu 8.04 repo。通过编辑sources.list来执行此操作：
sudo gedit /etc/apt/sources.list
然后在该文件的底部添加：
deb [trusted=yes] http://old-releases.ubuntu.com/ubuntu/ hardy universe
deb-src [trusted=yes] http://old-releases.ubuntu.com/ubuntu/ hardy universe
deb [trusted=yes] http://old-releases.ubuntu.com/ubuntu/ hardy-updates universe
deb-src [trusted=yes] http://old-releases.ubuntu.com/ubuntu/ hardy-updates universe
然后运行更新并安装g77：
sudo apt update
sudo apt install g77
你可能会很幸运，g77可能会立即为你服务。可能你会收到一条错误信息，例如：
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status
这意味着ld找不到库（libgcc_s）。自己找到图书馆，查看ld的样子，并在那里放一个链接：
sudo find /usr/ -name libgcc_s.so
ld -lgcc_s --verbose
sudo ln -s /usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so /usr/lib/x86_64-linux-gnu/
（您可能必须根据find和ld命令的返回修改链接命令中的目标和链接）
现在你应该好好去。我会注释掉你最后添加到sources.list文件中的行。有关详细信息，请查看my webpage。
