Linux support update after NI's new driver support

Closed this issue 4 years ago · 9 comments

This support article from August says that now you can install NI-DAQmx or NI-DAQmx Base on Ubuntu. Does this mean that this package can be modified to work with a linux system?

"Q: I am running a computer with an Ubuntu operating system. Is NI-DAQmx or NI-DAQmx Base supported on Ubuntu?

A: As of the NI Linux Device Drivers 2020, NI-DAQmx is supported on Unbuntu 18.04. Prior to this version, NI-DAQmx was not supported on Unbuntu. Please see the NI-DAQmx for Linux 20.1 readme for a list of devices supported by the NI-DAQmx for Linux driver."

adding linux support to NIDAQ.jl would be great! unfortunately, i won't have access to a linux box until the mandatory work-from-home order for me is lifted. care to take a stab at it?

Seems like it shouldn't be too difficult. I'll give it a try.

When I was producing the Julia file with Clang (with DAQmx version 20.1), I got the following warning massages. Is there a way to work around this or is this fine?

Answer 3 · 2020-09-13T14:28:07.000Z

Could you provide some help on the "manual edits" for constants_V<version>.jl and functions_V<version>.jl files for DAQmx version 20.1.0? As long as that's taken care of, I can add linux support and test it on a linux machine.

Answer 4 · 2020-09-20T14:08:29.000Z

what error messages are you getting when you use the unaltered Clang output? those are the ones you need to address with manual edits.

Answer 5 · 2020-09-20T20:11:43.000Z

the only errors I got are:

the VarArg error posted above
and at the precompilation time, const CVICALLBACK = CVICDECL (this was resolved by removing the line as instructed for the earlier version).

With DAQmx 20.1.0, I can successfully load the package on linux (Ubuntu 18.04). However, unfortunately, I can't test it with a device since it looks like that the Linux DAQmx doesn't support the lower-end USB DAQ boards. I currently don't have access to a non-USB board (hopefully NI will update to support the USB products in the near future).

Answer 6 · 2020-11-11T17:40:42.000Z

Updates: back to work where I have PCIe-6321. I was able to make it work on Ubuntu 18.04 with DAQmx v20.1.0. See #28

Answer 7 · 2020-11-19T12:43:42.000Z

closed by #28

Answer 8 · 2020-12-15T00:48:50.000Z

@bjarthur Could you make a new release with the current master—which includes the recent linux support. When I made the linux support, I set the next version number to be 0.6.0 in the Project.toml
