Hello Petro,
Did you use any specific feature from boost?
Most used features from boost were integrated to newer versions of C++.
I used C++-17 in a project and it worked fine.

Hi Greg,
When I thought about this issue, my 'solution' was using NuttX as a library :-/
That would work for a single application, but we lose a lot in
application architecture using the NuttX tree.

advised as a not-recommended
Hi Peter,
Yes, I intend to use it for simulation only.
It is for a personal project. I already have a Ubuntu based desktop

would be better.
I will try to figure out what is going on.
Thank you for all your help.
