linux visa crash

[sps]

I am working on Linux with LabVIEW 7.0, communicating with a serial device.  I recently downloaded the latest NI-VISA for Linux (NI-VISA 3.4). I previously had NI-VISA 3.0 (I think) installed. Now when I run my program LabVIEW and my program disappear into thin air. I can even make this happen by trying to open the Serial Port Init VI that contains the VISA commands.

Thanks for any suggestions.

Hi Sam,

What exactly happens when your program disappears?  Is LabVIEW simply closing?  Do you get an errors or logs?  What version of Linux are you running?  Have you been able to reproduce this on a different computer?  It sounds like your installation might be corrupted if simply opening on of the native LabVIEW serial VI's causes this to happen.  You may need to uninstall and reinstall.

Hope this helps,

Thanks for the message. The problem was with the installation.

In order for the installation to work I had to perform both of the steps outlined in the "Installation FAQs" of the readme file. Note that in step 3 of the installation instructions the example shows how to add the environment variables in csh. The way to do this in bash is as follows: #export VXIPNPPATH=/usr/local/vxipnp.
