Hi all!

I have the same issue on CentOS Stream and the latest linux driver package (


Searching the internet doesn't gave much more than this thread. Was anyone able to resolve this problem or could point me to some resource?


Any help is really appreciated!


Best regards from Germany

Have you searched your entire hard drive to see if it is there.  I have been fighting problems on Ubuntu with the runtime.  I ended up fixing the runtime problems by creating symbolic links in the /usr/lib64 folder to the places where the runtime was installed.  I wouldn't think you would need to do this on a supported Linux distro though.

I just had more or less the same problem (only the libni part).

But I have this problem only when I'm using the RTE, not the full LabVIEW.


I just copied the links and library from one PC to the other and I don't have anymore the error.


--> I attached the libraries in the tar file, it needs to be untar from / (and via root user of course).


Those files comes from 2020 version.


I don't have the problem with libnipalu anymore, but I had it in the past.



CentOS Stream is not supported by LabVIEW, I'm quite sure that the kernel is too recent.

ni-visa works on kernel 4.12.14 openSUSE Leap 15.1.

I had some problems with ni-visa on CentOS 8.
