VIs developed under XP not working on Linux

[CyGa]

Hello,

After calling my NI national support an engineer told me that the code developed under XP is compatible with LV running under Linux (OpenSUSE 11.0).

But some of my VI crash LV under Linux (see some of them in enclosed VIs). Each time, when restarting LV, the investigation pop-up says that the crash comes from "fontmgr.cpp".

Is there any solution to force LV to open these VIs ? I wouldn't like to re-build them entirely...

Hi Zyl7

See if this helps: http://digital.ni.com/public.nsf/allkb/F19E053DE554BE04862573D300018F37

I couldn't test it, because i'm using LV 8.5, but it will probably solve your case. If you get the same error, attach your VI's in LV 8.5 version, so i can test them.

Code is compatible across OS's unless you use platform specific functions. There are a lot of VIs and CTLs missing but one of your VIs is using .NET. This is windows only. The LabVIEW help shows OS limitations for a function.

Thanks THN !

It solves the problem. But as soon as I close the terminal, LV closes too. Is there any way to launch LV without this command or enabling to close the terminal when LV is started ?

That's simply setting an environment variable. You could include that in your startup scripts. See the documentation on the OS on how to do this.

Well, that's something i dunno..better wait for a NI Engineer reply.

I wasn't excepting that too. But if you search for that issue, you will probably thing more stuff about it.

Thanks for your reply.

Do you have any source talking about this ? I can't find anything on startup script / Labview /lang=C ...

Hi Zyl7,

Not really, i can't find any more support related to it. You better try ask that to a NI Engineer, that's a bit strange since your mainly error has been solved. There must be some other kind of conflict between what you've done in linux and bringing it to windows. I've search some other things related, but it probably won't help much.

Try to get the last Labview version, if you don't already have it.

Sorry, but i really can't help you much more.

You're not going to find something specificy to that. You need to search for how to setup environment variables in your shell. The document that was initially pointed to by THN tells you how to set the environment variable within a terminal window. This only applies to that terminal window. However, you can include the setting of the environment variable as part of your profile so that once you're logged in then any terminal window you launch will have that environment variable set. This can be verified by opening a new terminal and listing the environment variables.

As I indicated, this is a Linux thing. You need to find out what shell you're using, and what GUI you're using so that you can determine which file to modify. For example, if you're using the bash shell you'd likely modify the .bash_profile.

It's possible that some NI engineer who works with LabVIEW Linux will know the answer, but you'll probably get a faster answer if you just Google, or hit some of the Linux boards and search around some of the FAQs.
