32-bit DAQmx library for 64-bit Linux

[znapi]

I have a 32 bit application that I need to link with libnidaqmx.so. All the downloads I could find were for 64 bit versions of this library. Does there exist a 32 bit version of this library that supports RHEL 8? My operating system is 64 bit.

Excerpt from NI-DAQmx 2023 Q3 for Linux/x86 64-bit Architecture Readme

NI-DAQmx requires a 64-bit distribution and does not support 32-bit applications

NI stopped supporting 32-bit application development for LabVIEW for Linux somewhere in the 2017 timeframe. I would guess that is also the time they discontinued support for 32-bit drivers. Redhat 8 having its first release on 2019-05-07 is likely not supported by DAQmx before 2020.

Thanks. Are there 32 bit libraries available for RHEL 7 then?

NI-DAQmx Base supports 32-bit Linux. See Programming Data Acquisition for Linux with NI-DAQmx Base
