Re: [Plplot-general] newbie question

[Ali M. <so...@sy...>]

Hi Alan,

I think I did manage to generate the dll. Now I am trying to run the example
programs. I am getting following when I run.

C:\>java plplot/examples/x01

Plotting Options:
 < 1> win3       PLplot Win32 Window
 < 2> plmeta     PLplot Native Meta-File
 < 3> ps         PostScript File (monochrome)
 < 4> psc        PostScript File (color)
 < 5> null       Null device

Enter device number or keyword: 1

*** PLPLOT ERROR ***
Unable to open or allocate memory for font file
Program aborted

Please help

Thank you

-Ali
