Update...
I downloaded the latest NI-VISA w/ 64bit support - still having problems...
Now downloading the latest 488 software. The NI-VISA package did not appear to update the
source for gpibprtk.ko. So for now the problem still stands.
Any help appreciated
Thanks,
Steve.
Hi All,
I perhaps posted this in the wrong group, so I'll post it here.
Setup:
Using redhat enterprise 5 on a 64 bit dell workstation. Labview professional 8.6 fresh install.
I need to get NIVISA configured/running to communicate with test instruments on a LAN using VXI-11.
Don't have a GPIB card - all communication/control will be over a LAN/TCPIP.
Problem:
Can't run VISA utilities because module gpibprtk.ko can't be found.
Searching the forums, this seems to be a 64bit / 32bit issue. Running updateNIDriver and observing the output gets me to this:
..........
/bin/mv objects/gpibprtk.ko objects/gpibprtk-interfaceFile.ko
ld -r objects/gpibprtk-interfaceFile.ko objects/gpibprtk-processed.o -o objects/gpibprtk.ko
ld: Relocatable linking with relocations from format elf32-i386 (objects/gpibprtk-processed.o) to format elf64-x86-64 (objects/gpibprtk.ko) is not supported
make: *** [objects/gpibprtk.ko] Error 1
ERROR: failed to build gpibprtk.ko
gpibprtk.ko failed to update.
WARNING: could not unload module nipalk from memory
/usr/local/natinst/nikal/src
nipalk.ko successfully updated.
Update of National Instruments drivers failed.
...........
it would appear that the module is 32bit and won't link to a 64 bit kernel. I'm by no means the expert on compiling and linking, but the link
error seems to be the central problem - no link = no module = no workie.
So, I assume I need this module loaded to get my VXI-11/LAN stuff to work even though I'm not using GPIB - at least not the hardware interface.
I've attached the output from updateNIDriver for reference. All software is from the CD - workstation has no external access - although I can "sneakernet" stuff onto the system.
Thanks,
Steve.

Update #2.
I downloaded and installed ni4882-2.5.4b1-release.tar.gz. This contained the source for ni488k.ko which compiled and installed OK.
VISA interactive utility can now talk to a LXI instrument on the lan, so it looks like we're up:)
I assume the new version of NI-VISA now calls ni488k.ko to be loaded if not there rather than gpibprtk.ko.
I would have thought the driver would have been included in the NI-VISA 64 bit ISO update package since I thought that this is where the orginal 488 source files came from, but apparently, you need both - maybe because the 488 driver is still in beta?
So it appears that I've answered my own question - by installing some updates, but I'll leave this here in case it is useful to someone else.
Since the workstation is stand-alone, the automagic update approach is not an option - the old fashion read the error msg and solve it is required here:\

I thought I marked this earlier, but apparently not. The fix I posted worked.
