linking with ni causes stdlib's system routine to not work?

[Jason Newton]

So basically, I was wondering why when I add "-lnidaqmx" to "g++ test.cpp", the file "omg" isn't created - yet when I omit the linking flag, "omg" is created.

Using fedora core 4 with 2.6.13.5, nidaqmx 8.0m, and gcc/g++ 4.0.2.  Let me note that all ni apps installed work fine, and all examples run fine.
As a further puzzler, things work as expected when ran under valgrind.

Jason,

I've compiled and run your code on Mandriva 2006 and it worked as expected, with and without the nidaqmx library. This is using gcc/g++ version 4.0.1-5mdk. Perhaps this has something to do with Fedora Core? Have you seen this on any other distributions? More importantly, is this behavior causing problems with your end application?

Hope this helps,

It seems this is related to kernel version.  I decided to try 2.6.12.6 and the sample code now works fine.

On another note, is it possible for NI to keep a list of supported kernels?  I recall having fun with kernel versions for nidaqmxbase 1.5 as well, and knowing which are known to work without problems would be a big help.

Jason,

Rather than support kernel versions, we choose to support specific distributions. There are other things beyond the kernel that can cause problems with our software and drivers. Here is a link of supported distributions.

Hope this helps,
