Re: [Omniprint-user] Trying to get Omni library to work

[Geoff C. <geo...@bj...>]

  I have recompiled ghostscript, changing fDebugOutput to 1. The output I saw 
was exactly the same as before. Ie, there were no extra diagnostic messages 
displayed to indicate some problems.
  
  Are there any other suggestions?
I had a look into the code. It seems that the error message is being 
generated in the gomni.c, line 650,  after checking something:

 if (!pDev->vhOmni)
 {
         // Failure!
         fprintf (stderr, "\n<<<<<<<<<<<<<<<<<<<<<< ERROR 
>>>>>>>>>>>>>>>>>>>>>>>\n\n");
         fprintf (stderr, "Error: Could not load libomni.so!\n\n");

  However, I have no idea why pDev->vhOmni is NULL, and I don't have the 
skills to track it down.

  Thanks for anyhelp

  Geoff
