Labview 8.5 Linux, I can't use DAQmx Base constants

[gronfelt]

I'm trying to move an application from Windows to Linux, I'm running RH5 Workstation with LV 8.5 and the newest NI-DAQmx Base installed. I've created tasks using the NI DAQmx Base Task Configuration utility.

However, when I create a Task constant in my block diagram, I cannot select any tasks with it, the arrow down-button is just greyed out. The same goes for the other I/O-constants (Physical Channel constant and Device constant). I've tried typing the task name, but the program just exits with an error.

It seems as though LabView doesn't know where to get information about devices and defined tasks, do I need to do anything to tell LV where to look?

A mysterious thing though, is that I've tried running a sample program, which makes use of one of the predefined tasks and that seemed to work (at least it did not exit with an error). Even more mysterious: When I tried to run the same sample now, it tells me that it can't be opened since I'm running LV 8.2.1, even though I'm running LV 8.5.

Any ideas of what to do? Would it be meaningful to uninstall DAQmx Base and install DAQmx instead (i chose DAQmx Base since the last DAQmx-version was from 2005 or so).

Thank you in advance.
