[Linux-gpib-general] GPIB libs on 64-Bit machine

[Martin O. <mar...@de...>]

Hello all,

I want to write gpib-DAQ software for a Keithley, which is accessed via 
gpib-usb-hs from National Instruments. For this I took the gpib-library 
from sourceforge : linux-gpib-3.2.09. The OS of my PC is Scientific Linux 
4. I successfully installed libgpib on a 32-Bit machine.
When I did the same steps on a 64-Bit machine I failed. The installation 
itself worked without problems. Also the modules are loaded (I checked 
this with help of lsmod). All permissions are set correctly (I even tried 
as root). By 'cat /proc/bus/usb/devices' I saw that the gpib-usb-hs was 
detected correctly. So everything looks fine.

The result on the 64-Bit machine is, however, when starting 'ibtest' and 
accessing the board:
> 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: gpib-usb-hs
> trying to open board named 'gpib-usb-hs'
> libgpib: IBOPENDEV ioctl failed
> libgpib: ibfind failed to get descriptor
> failed to open board

Also trying 'gpib_config --minor 0' leads only to
> failed to bring board online
> failed to configure board
> main: Cannot allocate memory

In the case of the 32-Bit machine everything worked fine.
Has someone an idea what's wrong? I'm grateful for any idea.

Cheers,
Martin

PS: Here some output of several things:
