Labview demo for linux

Hi
I searched through the forum to se if there where any Linux demo version for Labview. It showed up that this did not exist. However, as most posts sugested when I searched for this where from 2004 and earlier I dear to ask the same question again in hope that things has changed (and with a litle question for why isn't it available if not).
Thanks

The reason is quite obvious. Since only the Windows platform uses a license manager, all other platforms need a special recompiled LabVIEW version that has the evaluation limitations compiled into it. Creating that executable is the smallest hassle, but creating an installer and testing it to work on the list of platforms NI guarantees LabVIEW to work on is a major task. Considering that LabVIEW for Linux is hardly sold for commercial applications but mostly used as part of an educational (site) license, the economical benefit for such an extra effort is very hard to justify.

Labview player for linux?

I have a Labview VI running on my Windows platform. I developed it using the Windows version of Labview 7.1. I used the Web Publishing tool to make the display available online. I have verified that I can see the display running in real time using IE on a Windows machine.
Other machines in our LAN are running Linux, and cannot view the site in real time. For example, Mozilla asks for a plugin, but I can not find Labview Player for Linux anywhere. Can anyone help me get the Linux machines to see the real time site that is being hosted from a Windows machine?
Thanks

I don't think that there is a plug-in for a linux system to be able to view the published LabVIEW front panel.
Wait! Try looking at this link:

Labview 7 for Linux on Redhat9,NI example Finder not working.

I have Labview7 for Linux on Redhat9, installed at /usr/local/lv71. "NI example Finder" is not working, the function of browser, search,submit,none is working. When I try to close it, the window looks dead, cannot close it. I will force to close it. What is the problem? Where are the examples?
Another question: the simple help text is working, but the details help is not working. I can open the help file by Mozilla. But I want the help could be linked, like what it is in Windows platform.
Thanks

Hello �
If whenever you type �labview� at the prompt, LabVIEW 7.1 is launched, it probably means that the paths are setup to launch 7.1 but it doesn�t necessarily mean that you do not have LabVIEW 7.0 installed.
If you only installed LabVIEW 7.1 in that computer, it is possible that somebody else had installed LabVIEW 7.0 before.
What I suggest doing is to run the UNINSTALL scripts for both, LabVIEW 7.0 and 7.1, and reinstall LabVIEW 7.1 as root, not as user.
Hope that helps!

Is labview same for linux and windows?

hi,
Right now, i am using labview 6.1 and 7.1 windows version. can i use the same windows version for linux also?

You need to get the Linux version in order to run LV on Linux. You can open and run the VIs you save in Windows in the Linux version and vice-versa, but some things are Windows-specific and will not work (for instance ActiveX, .net, toolkits which are only supported on Windows, etc.). Also, when you open your VI in Linux, LV will tell you it was changed, because the compiled code is saved as part of the VI. The compiled code for Windows and Linux is different, so when you open a Windows VI in Linux, it is recompiled.
You might wish to do a search for "Linux" to see more specific details.

LabView 8 for Linux application distribution

I have build an application for Linux using labview application builder.
I now have a app.o file, but the application builder does not create a distribution package (unlike the windows application builder where it creates a data.cab that contains the application and runtime engine parts).
How do I distribute the runtime engine components (or know what they are and where they are)?
How do I tell an end-user how to install my program and the runtime engine?
Note: This application does not interface any hardware. It reads a file using the command line and writes another file.

If the built application does not use any NI drivers, or NI-VISA then the only other component you will need is the LabVIEW Run-time Engine. You can download the version of the LabVIEW RTE that matches the version you built the application with from our download site http://joule.ni.com/nidu/cds/fn/p/sn/n17:runtime,n19:Linux,n23:4/lang/en.
To install your application on another machine you should only need to install the LabVIEW RTE rpm(s) using rpm.:
rpm -Uvh *.rpm
Then copy your binary file your built with the application builder to the new machine and run it.

FieldPoint and labview for linux

Can I access to Fieldpoint Ethernet modules, FP-1601, from labview 8 for linux?

Hi,
You cannot use fp-1601 ethernet with Linux. That is because the communication protocols are privated from NI and are only for windows.
U can use Linux with Fp-1000/1001-2000/2010. See attached document for longer explanation,

What LabVIEW for Linux based on ?

Whar is the way LabVIEW 7 for Linux communicate with
DAQ boards ?
Is it the same as on Windows ?
Can I write application on 'C/C++', that use only low level library that LabVIEW based on ?
It this possible on Windows with Visual C?
With LabWindows it is possible.
More precisely, I may use only NI-DAQ library and do
nothing with IDE of LabWindows.
But if I right, neither LabWindows nor NI-DAQ/NI-DAQmx is't for Linux.
I have some experience with LabWindows/CVI, but nothing
with LabVIEW.
What is principal difference between them in low level communication with DAQ boards ?
Thanks.

No! LabVIEW for Linux does not come with any DAQ libraries. There are
basically two options at this time:
You can download the NI Measurement Hardware DDK from NI and the
according LabVIEW VI libraries or you can use Comedi.
> Can I write application on 'C/C++', that use only low level library
> that LabVIEW based on ?
The NI Measurement Hardware DDK (and Comedi) is a C based interface with
precompiled binary libraries which you can use from your C/C++
application. The NI provided VI libraries allow access of that API from
within LabVIEW.
> It this possible on Windows with Visual C?
The NI Measurement Hardware DDK is also available for Windows in which
case it consists of a number of DLLs, header files and examples. They
are callable from any C application. But this DDK is in principle a low
level API which often requires you to go down to register level directly.
You can also call NI-DAQ (the API LabVIEW uses on the Windows platform)
from your C compiler, Visual C or whatever, but that API is not
available on non Windows platforms (oh well there was an old version for
MacOS and Sun Solaris but that is I don't know how many years old).
> With LabWindows it is possible.

LabWindows just provides FrontPanels to the NI-DAQ libraries. It is not
a LabWindows implementation of NI-DAQ but instead it accesses exactly
the same libraries LabVIEW does or your own C application would.
> But if I right, neither LabWindows nor NI-DAQ/NI-DAQmx is't for Linux.
No! They aren't and except hopefully for a limited DAQmx library
probably never will be.

> with DAQ boards ?
LabVIEW is a graphical programming environment whereas LabWindows CVI
uses C programming. The difference between LabWindows and a standard C
compiler is the standard built in support for many libraries used in
Test & Measurement, Data Acquisition etc, the extensive library of
graphical user interface components and the FrontPanels provided for all
the library functions. Nothing you couldn't do with a normal C compiler
nowadays, but they are very tightly integrated in CVI and generally
working together well.
As an experienced LabWindows CVI user it may be better to stay in that
environment than starting to use LabVIEW. LabVIEW is similar in what you
can do, a lot more comfortable for the casual programmer, but on the
other hand also a little patronizing in more advanced features. As much
as it is comfortable to generally not have to worry about memory
allocation and code frameworks before you even can start to implement
your first algorithme, it can get in the way when you try to do high
performance operations as you not only don't have to worry about memory
allocation but you have in fact limited and only indirect influence in
how memory is allocated.

Is there flexmotion for linux?

I do not have the LabVIEW software for Linux yet but I was wondering if the Flexmotion that one uses in Windows is avaliable in the Linux version? I am going to try to use my NI-7344 that I presently have in a Windows system in a Linux system. I have found the unsupported Linux drivers for the NI-7344 but I did not know if there was any Flexmotion software. This would just make my life a bit easier. Thanks.

Flexmotion does not exist for Linux.
There is a Driver Development Kit to allow you to make a driver for any platform, and due to the nature of the 7344 it is actully relatively easy to use. Please call into our support line to get your hands on this DDK.
Hope this helps,

How to create a c++ shared library (.so) for linux real time (for myRio) with Eclipse to use in LabView?

I tried already these Tutorials and Advices but I didn't find a solution:

- and some more
I want use c++ codes on linux real time. For testing reasons I want to have a function that adds 2 values and gives the result.
I've done these steps:
1. writing a c++ file in Eclipse (see screensot 2)
2. building a shared library (.so) from my c++ project in Eclipse (with Cross GCC)
3. putting this file on myRio (path: /usr/local/lib/)
4. creating a VI that calls this library from Labview with a "Call Library Function Node" (see screenshot3)
5. Setting the properties for the "Call Library Function Node" (see screenshots 4-7)
After I run this VI i get this error message: LabVIEW: (Hex 0x627) The function name for the ... node cannot be found in the library. To correct this error, right-click the Call Library Function Node and select Configure from the shortcut menu. Then choose the correct function name. (see screenshot1)
I've tried a lot things to solve this problem but I couldn't find a solution. Would be very happy if anyone can help me. I guess that I have to edit my c++ code to export my function (symbol). But I have no idea how to make it. I also tried it with a dll file in the same folder but it didn't help.
Perhaps someone can send an example which works on myRIO.
Thanks!

screenshot7

can see it in the screenshot8 there is a function called "_Z8AddierenddPd" instead of "Addieren". I copied this name to Labview (see screenshot9) and it worked.
I'm sure that there is a way to compile the shared folder with gcc without decorations (mangling). But I don't know how. If someone has a recommendation I would be very glad!
Prepend each function declaration that you want to be available without name decoration with
extern "C" <your function declaration>
Or if you have multiple functions you want to export you can in the header file where you declare your functions simply use:
#ifdef __cplusplus
extern "C" {
#endif
<all your function declarations>
#ifdef __cplusplus
#endif
