Install the g77 compiler in Linux

Nowadays, the compiler is changing rapidly, and accidentally lags behind the times. In the past, many programs were compiled with g77. In the new Linux system, g77 has been completely replaced by gfortran. However, the problem is that gfortran is not fully compatible with g77 in the past, and it is unlikely to complete the modification program .. Helpless, so I had to explore for myself as an amateur. I use Ubuntu10.10 to automatically install the new gcc version (but g77 is no longer available ). I installed g77 using the following method. First

2. Install aptitude
Sudo apt-get install aptitude

3. Run the following command:

Sudo aptitude update
