Having been using the Open G Zip Tools on both Windows and VxWorks targets for a long time I just ran into the issue of compatibility with Linux RT... I'm sure I can find an alternative on Linux RT, but the otpimal solution of course would be to have the existing toolkit also support Linux RT Has anyone compiled and modified the kit already for Linux (or set up a nice replacement)? Are there any plans to add such support in the official version? MTO

I have installed Labview 2020 on Dedian Buster using the rpm to deb conversion method via alien. Due to Architecture mismatch i deleted the *i386.rpm files before conversion. My Problem is that after creating a project at "Build Specification"-> "rigth click" i am only able to select "Source Distribution". Application does not show up as an option. I will be grateful for any suggestions. Thank you in advance.

[cross-post] I'm starting to use LabVIEW 2020 Sp1 on OpenSuse 15 and the event structure editor - I mean the dialog to add / edit handled event - seems to have localization issues. Also, a difference from Windows LV, if a constant is connected to the timeout terminal, LV requires that you handle the timeout event... weird. Is it normal / known to have these "issues"?

Out of the box text in the icon editor looks awful. (See attached image, which is better looking than most.) (Yes, even with small fonts: https://forums.ni.com/t5/Linux-Users/Labview-Icons-under-GNOME/gpm-p/3379530.) Details: LabVIEW 2016 64-bit, CentOS 7 Linux OS We have tried many things to get this to work, to no avail. Does anyone have a solution?

I wanted to cross post metux's discovery here asap, and have a separate discussion. Metux's original post: The recent Linux driver package introduces a CRITICAL security vulnerability: http://www.ni.com/download/ni-linux-device-drivers-2018/7664/en/ It adds additional yum/zypper repos, but explicitly disabling package signing and using unencrypted HTTP transport. That way, it's pretty trivial to completely takeover the affected systems, by injecting malicious packages. DO NOT INSTALL THIS BROKEN SOFTWARE - IT IS DANGEROUS ! CERT and BSI are already notified.

More out of curiosity than of hope: has anybody any idea why SVs are almost unsupported on linux? By almost I mean that controls and indicators cannot be bound to shared variables, and that shared variables cannot be programmatically created and looked up. I know that SVs hosted on windows can be accessed in linux LV using datasocket nodes, but that is all it gets. And it has been said that datasocket is despicable. What are the missing pieces that make SV windows-only? I didn't find much in the canonical places, so I posted a dumb zero-kudos attracting idea.

Hi everybody, Currently working on VeriStand custom devices, I'm facing a 'huge' problem when debugging the code I make for the Linux RT Target. The console is not availbale on such targets, and I do not want to fall back to the serial port and Hyperterminal-like programs (damn we are in the 21st century !! )... Several years ago (2014 if I remember well) I posted an request on the Idea Exchange forum on NI's website to get back the console on Linux targets. NI agreed with the idea and it is 'in development' since then. Seems to be so hard to do that it takes years to have this simple feature back to life. On my side I developped a web-based console : HTML page displaying strings received through a WebSocket link. Pretty easy and fast, but the integration effort (start server, close server, handle push requests, ...)must be done for each single code I create for such targets. Do you have any good tricks to debug your code running on a Linux target ?

Hi all, I've got a customer that wants to zip/unzip files on their cRIO-9035, so I had them playing with the OpenG Zip tools to see if it would fit their needs. Although they've found that they can zip files on their cRIO just fine, they find that they get disconnected from their RT target and the shell shows the following error message: LabVIEW caught a fatal signal 15.0 - Recieved SIGSEGV Reason: address not mapped to object Attempt to reference address: 0x0x10000000 stdin: is not a tty The zip file they're testing with includes two simple .txt files with short strings in them ("booya" and "booya2"). This file unzips just fine on the host PC with the "ZLIB Extract All Files To Dir" VI, but when copied over to the cRIO and unzipped via the same VI, it only unzips the first text file and the resulting file doesn't have any text in it. I've attached a copy of the project and the zip file I used to reproduce this behavior using a cRIO-9033 that I had on hand. (The only thing I can't provide is the cRIO >_<) Could anybody tell me what I'm doing wrong? Any suggestions as to what other workarounds I could take to zip/unzip files on a LinuxRT target would also be very much appreciated! Regards, Tamon Unzip on cRIO-9033.zip

Hi LAVA, I need your help! I've recently started updating a system from LV8.6 to 2011SP1, and have ended up in confusion. I deploy the system as executables on two different machines running Linux Ubuntu, one a laptop with a single processor and the other a panel PC with two processors. What happens is the on the first, single-processor computer I see a dramatic fall in the use of the CPU. The other in contrast shows a dramatic raise in CPU usage. The computers do not have LV installed, only the RTE:s. Machine1 (1* Intel® Celeron® CPU 900 @ 2.20GHz): CPU% with LV8.6: 63% CPU% with 2011SP1: 39% Machine2 (2* Genuine Intel® CPU N270 @ 1.60GHz): CPU% with LV8.6: 40% CPU% with 2011SP1: 102% In the second machine the max CPU is 200% since it has two CPU:s. The load seems to be pretty even between the CPU:s. Why is this happening, and what should I do to get the CPU usage down on machine2 (the one being shipped to customers)? /Martin

Hello All, I am developing the application for Linux using LabVIEW For Linux under openSUSE 12.1 & 11.4 versions. My application would be a stand alone application running on the system. What I want to achieve is :- a). An application which would serve the tasks defined by user and will do that tasks continuously. Here this system with LabVIEW application will be acting as the Server. b). Another application which would act as user interface to client for configuring the tasks & this tasks will be sent to Server System as mentioned in point no. a. Here the LabVIEW application will be acting as User Interface Client. Now my Questions are:- 1. What is the bare minimum requirement by the LabVIEW application from the Linux OS to run the LabVIEW application without interface or X window in Linux or the LaBVIEW application in the console format in Linux. 2. What is the bare minimum requirement by the LabVIEW application from Linux OS to run the LabVIEW application with LabVIEW GUI interface. In above both system is not considered as for development, considered as only for deployment point of view. Development System will be different. Please give your valuable suggestions or help or guidance if anyone has done this before. Thanks & Regards. Nilesh

Hey guys, I am currently having some issues with a FPGA program with Softmotion not compiling. We are running out of options in terms of how to get this FPGA program compiled. So my question is does compiling on Linux have a different probability of compiling FPGAs? I have heard that Xilinx Compiler is meant for Linux so it runs more efficiently and faster, so I was just wondering if the compile method was different as well -
Mostly for fun, I have concocted a way of acquiring video using Labview for linux, to mend for the unavailability of IMAQdx. The idea is to grab via v4l2, actually through the handler libv4l2, and to display simply via the picture control. I have tested this for the moment only with webcams at 640x480 on LV11 and 13 (both 32bits) on two different installations of Ubuntu 12.04 64bits, and it works. This means v4l-utils 0.8.6-1ubuntu2, 32bit. Attached is a proof of the concept, essentially a translation of the Appendix E example to the linuxtv API, saved for LV11. I include also a loose set of tools I built myself in order to parse the relevant headers and construct semiautomatically the necessary typedefs (LV13, no backsave out of lazyness). I have two questions: -Is this insane enough to qualify for this forum, or do I have seriously seriously to exaggerate? -Is someone interested in helping me to expand the exercise, checking portability on other distributions and versions of v4l2, other supported image formats, more robust packaging & so on? Intention would be to release a package under GPL. Enrico grab11.zip Import_headers.zip

Hello, I managed to install VI Packet Manager in Ubuntu Oneiric and downloaded many libraries. The problem is I cannot see those libraries in my LabVIEW 2011. I saw Packet Builder is only available for Windows. The VIPM downloaded the ogp files and some other files under its cache folder but I have no idea how to access them in LabVIEW. This sounds extremely trivial and may be that is why I was not able to find the solution after searching for couple of hours. If there is no packet builder in Linux then why do we have VIPM? How do we use the downloaded libraries? Thanks, Şenol
