why don't you post the link to the youtube video?

maybe this VI comes from a package that is not installed by default

I'm confused, .NET works on Linux?

i guess you're stuck with the 2d picture control

NI-IMAQdx supports NI Linux RT so I guess you could dig there.

NI has never been extremely active in Vision, I doubt Linux  support is on their roadmap, good luck to you!

silly question : does it work if you don't use a cluster in the dll but independent indicators (2 strings, a float and an int) ?

Hi Thomas,

First, you need to make sure that your dynamically launched VIs are included into the EXE, to do that, in the build specs, in 'Source Files' you have to add these VIs in the "Always Included" list.

Then there path for these VIs will not be the same when you run the code and when you run the EXE

- in source the VI path is C:\Users\thomas.granito\Desktop\ProjectName\Test.vi

- in EXE it will be C:\<where-ever-your-EXE-is>\App.exe\Test.vi

So the easiest will probably be to use a relative path to the main VI.

Okay attached is an updated version that I think supports the changes I made.  It reads the registry in 32 or 64 bit LabVIEW finding the path to the shared installation location.  In Linux it tries both the libeay32.so and libcrypto.so.  In both cases it keeps the found path in a feedback node for later calls.  I also added outputs instead of void for calls, but am now realizing this version doesn't do anything with them yet.

why on earth did you use a ring and a property node on that ring to get the method (md4, md5, etc.)?
an enum with a format into string seems nicer.

A, also, if your VI used on Linux and built as a shared library (in order to run the app as a service) then it causes a crash.
With enum+format into string, it works.

I guess we all have a price.

This reminds me of a brilliant scene from "nueve reinas" https://www.youtube.com/watch?v=AcsfBeTAuSQ

cross-posting is ok, just mention it please

i know I'm a bit late on this one, but there is an idea on the exchange about exactly that

quite frankly I have no idea... but there is another discussion in the LAVA lounge created a few hours before your question :

all I've seen is this (on the french section of NI forums)

it's working for me

good job!

yep, still no luck on my side

where does the original image come from, a camera supposedly... which brand/model?

also, can you post you code?

i have ubuntu 20.04 and I don't have gcc installed, is it required?

i have gcc 9.4.0, shall i upgrade?

I see, I'm often struggling so files dependencies.

Making a single PostgreSQL VIP (starting from Dr. Powell's repo) that would support Linux, NI Linux RT and Windows took quite a bit of effort.

@Porter I can't dedicate time to dig into this issue, but I can run some test if you post a new VIP, good luck to you!

I can't get it to work on Ubuntu with LV 2020 SP1

LabVIEW won't accept the so file and keep asking me to point to the file.

I've already seen some weird behaviors with CLFN on Linux when feeding the library path on the diagram but if the case of your 64 so file, even if I create a new VI, place a new CLFN and try to link to libmuparser-x64-lv.so LabVIEW then prompts me to find 'libmuparser-x64-lv.so'

here :

hope this helps

there are examples in LabVIEW, see this page on NI Website : https://www.ni.com/docs/en-US/bundle/labview/page/glang/array_to_cluster.html

If you can't find the example, I'll post one here.

new release in my fork : https://github.com/AntoineChalons/lv-toml/releases/tag/releases%2Fv2.3.2

what's new : I've improved the error reporting when there is a typo in the value, ex :

[cluster]
some-numerial-value = 10
other-numerial-value-with-a-typo = 10s

The error source will quote the line at fault and give you the line index, something like "Parsing error at line 3 : 'other-numerical-value-with-a-typo = 10s'

@drjdpowell on both Windows and Linux (Ubuntu) with LV20 we have crashes (not 100% of the time though) when we send SQL command that break the constraints. After a lot of testing my colleague @kdevelle found the issue and fixed it, we will soon publish the fix in the repo (dev branch)

Merci Antoine, it was usefull.

Glad I could help.
I don't think the "app store" like model is something NI is willing to invest effort on, they seem happy to let the community deal with it, from what I could see NI did the bare minimum - which is already not too bad - to give the community a reasonably good solution to handle licenses.

Again I've not used it myself, but I've seen people use, I hope it works out well for you.

I strongly encourage you to contact NI, and more specifically Nancy Henson or Eric Reffett (look them up on linkedin to see their role at NI) to give them feedback about the developer center on community.ni.com.

I'm not sure it's all up to date, but from the link I gave in my first response you should find all the existing doc & tutorials.

I've never had to go through this process, but I know many people who have.

Good luck to you!
