gnuplot error when running Octave script on Linux

[David Aldrich]

Hi

 

I have an Octave script that works fine when run by Octave 3.2.3 on Windows XP, but it fails when run by Octave 3.2.3 on Linux (Centos 5):

 

gnuplot> if (exists("GPVAL_TERM")) print GPVAL_TERM; else print NaN

                    ^

         line 0: invalid _expression_

 

error: Invalid call to strcat.  Correct usage is:

 

-- Function File:  strcat (S1, S2, ...)

 

Please can anyone help with this error? Does it imply that I have the wrong version of gnuplot installed?

Best regards

David
