NI and Purify do not work together

[vera]

We are trying to Purify our app and using Purify during linking. Although when we ran Purified app, it crashed with 'Fatal core dump' message at the NI libraries loading stage:

COR: Fatal core dump:
  * This is occurring while in thread 3829:

We tried to exclude NI libaries from Purifying process, but it did not help.

OS: CentOS 5.3 with rebuilt kernel stack size 8K

NI driver: 8.0.1

Did anyone try to do a similar thing? Any luck?

Any ideas what else I can try?

Any advice is appreciated.

Hello Vera,

DAQmx 8.0.1 does not support Red Hat or it's derivatives. Try installing DAQmx 8.0 - RedHat instead. This may still be difficult, but you would at least be starting with a version of DAQmx that supports the basic kernel.
