[Xenomai-help] C++ and Xenomai 2.4.0

Hello!
I need to run some methods of class as a task of Xenomai. I did a test  and
 initially there was no problem. Do you really agree with this? Is there any
problem to use C++ and Xenomai 2.4.0 ?

Thank you for help!
Best regards,

If you have one use-case which fails, please post a small example
here, and we will try to find a solution. For the moment, "object
instantiation" looks like a vague problem description.

Worry as much as you want. But you may want to save that for when 
something doesn't work ;)

We use Xenomai for a C++ userland application with a mix of real-time 
and non-real-time threads. We do not see any issues introduced by 
Xenomai wrt object instantiation. Of course, instantiating objects while 
you are in a real-time thread may affect performance so you may want 
most of those already allocated and ready to go when you need real-time 
behaviors.
