Hi all,
I need to program an old tektronix machine using the gpib port.
I have a c application written by someone for it. however on running the application I get an error
libgpib: ibBoardOpen failed to open device file /dev/gpib0
libgpib: No such device or address
libgpib: error in is_cic()!
I installed the ni488.2 driver and ni visa 4.5 on my machine following the link
http://decibel.ni.com/content/docs/DOC-6742#cf
however I was still having the same problem

Do I need to modify my gpib.conf file?

And I can see my device when I type visaconf
Am I doing something wrong here? or is my understanding that installing visa can help this C program find my device
also a very basic thing
ibtest fails
ibtest
Do you wish to open a (d)evice or an interface (b)oard?
(you probably want to open a device): b
enter name of interface board (or device) you wish to open: ni_pci
trying to open board named 'ni_pci'
failed to open board
Pease suggest as to what shoud I do? to
make the ibdev() function to work
