Here's a valid command line from my Debian running PC:

/usr/bin/dot -Tpng /home/fz/programming/Lisp/graphviz/todot-output.dot -o /home/fz/programming/Lisp/graphviz/todot-output.png

The above command takes a valid .dot file and produces a valid .png
file.

I'm trying to do it inside SBCL:

(run-program 
 "/usr/bin/dot" 
 '("-Tpng /home/fz/programming/Lisp/graphviz/todot-output.dot" "-o" "/home/fz/programming/Lisp/graphviz/todot-output.png"))

But I could not produce any file. Seems like the above run-program
has no file writing effect. How can I make SBCL
invoke the same command? What am I doing wrong? Is it about
passing parameters?

Any clues?

Thanks in advance.

Shouldn't this be:
(run-program 
  "/usr/bin/dot" 
  '("-Tpng" "/home/fz/programming/Lisp/graphviz/todot-output.dot" 
    "-o" "/hofz/programming/Lisp/graphviz/todot-output.png"))

Note the missing separation of the format switch and the input file name
in your example.

Thank you very much. After correcting my mistake I have also
added the required stuff to grab the output (even though this
one doesn't have much to output):

(with-output-to-string 
    (stream)
     (run-program 
      "/usr/bin/dot" 
      '("-Tpng" "todot-output.dot" "-o" "todot-output.png") 
      :output stream))
