Hi all,  
I am trying to test my installation of Dislin. I get an error that says

```auto
Fatal Error: Cannot open module file ‘dislin.mod’ for reading at (1): No such file or directory

```

This is the command I used

```auto
gfortran -L/usr/local/dislin/g95 -O3 dislin_test.f90 -o dislin_test

```

This is the program :

```auto
PROGRAM TEST                              
  USE DISLIN                              
                                          
  CALL DISLINI ()                         
  CALL MESSAG ('This is a test', 100, 100)
  CALL DISFIN ()                          
                                          
                                          
END PROGRAM TEST                          

```

fyi: The Dislin mod file is present in the linked directory.

I think you need to include (`-I`) the directory with .mod file in addition to linking to the directory with the static/dynamic library.
