make g77 command not found

Question

I am trying to make a project:

https://www.cs.virginia.edu/stream/FTP/Code/

it reports:

make: g77 command not found.

I saw this line in Makefile:

FF = g77

Can I change 'g77' here to something else to compile in the current OS, ex: Ubuntu 18.04?

Answer 1

change

FF = g77 

to

FF = gfortran 

works.
