I am trying to create a GUI for FORTRAN using DISLIN. I installed DISLIN in /usr/local/dislin folder and tried to compile some example programs given in the directory. g95link -a exa_f90.f90 I got the error message g95link not found. I wanted to know if "g95link" needs to be created first. Usually "command not found" error can be because the package is not installed or the path is not correct. I have gfortran in my machine. Is there a way to create link files simply by using "-lxxx" command?
