NI-VISA wrong ELFCLASS

[kaffeesurrogat]

Hello all,

i'm new to the user group and not an expert of Labview. I'm trying hard (for two days now) to install Labview on a gentoo multilib distro. I've removed and reinstalled all the stuff for several times now and I'm running out of new ideas of howto install labview. It should run together with a PCI 6229 - Card.

I've started with NI-VISA 17.0.0 for Linux.

The installationprocess did finish. I've updated the kernelmodules, and they are all loaded.

Here is lsmod:

1) Problem

Running visaconf I get the following error message:

Can't load library /usr/local/lib/liblvrt.so.15.0
/usr/local/lib/liblvrt.so.15.0: wrong ELF class: ELFCLASS64
To download the LabVIEW Runtime engine, go to http://www.ni.com/rteFinder?dest=lvrte&version=15.0&platform=Linux&lang=en

Well, it tells me to install LabVIEW2015RTE_Linux.tgz. I did this in my first installation cycle, but the error stays the same.

Any hints on this ?

Please have a look at the spoiler, there is an update:

Spoiler

64bit Libraries are stored in /usr/local/lib/LabVIEW-2015-64/
the links found by ls -l in /usr/local/lib were pointing on the 64bit variant:

lrwxrwxrwx 1 root root 15 Jan 19 12:21 liblvrt.so -> liblvrt.so.15.0
lrwxrwxrwx 1 root root 33 Jan 19 12:21 liblvrt.so.15.0 -> LabVIEW-2015-64/liblvrt.so.15.0.

so I removed liblvrt.so.15.0 and made a new link within /usr/local/lib/ using:

ln -sf LabVIEW-2015/liblvrt.so.15.0.1 liblvrt.so.15.0

visaconf is up and running 😉

2) Problem

Running lsni64 gives:

Scanning localhost for devices...

libnipalu.so failed to initialize
Perhaps you need to run updateNIDrivers
Aborted

I've found a 32bit version an 64bit version:

/usr/lib64/i386-linux-gnu/libnipalu.so
/usr/lib64/i386-linux-gnu/libnipalu.so.1
/usr/lib64/i386-linux-gnu/libnipalu.so.17.0.0
/usr/lib64/x86_64-linux-gnu/libnipalu.so
/usr/lib64/x86_64-linux-gnu/libnipalu.so.1
/usr/lib64/x86_64-linux-gnu/libnipalu.so.17.0.0
/usr/local/natinst/nipal/lib/libnipalu.so.17.0.0
/usr/local/natinst/nipal/lib64/libnipalu.so.17.0.0

  Please have a look at the spoiler, there is an update.

UPDATE:

I had to start: /etc/init.d/nipal start ... This gave me:


lsni64 => ...
Scanning localhost for devices...

System Configuration API resources found:
/sys/bus/pci/devices/0000:04:05.0

Again, any hints on this ?

I did no go any further with the installation during my actual cycle of the installation procedure cause I can say this will not  change if I will install Labview 2015,  nidaqmxbase-15.0.0 and LabVIEW2015RTE engine, as I did in the installation cycle before.

I hope, you can give me any hints 😉

Have fun,

Hello, any chance to use CENTOS 7.4?

For me this is the best linux with labview.

Please let me know.

Hey vphino13,

this might happen one day, right now I don't want to give up 😉
