as I mention in my topic "some issues with c++", i am implementing a real time OS for my master thesis.
this OS will be used later in car industries for testing porpose. I will need also later a thread support (like pthread). this will help me to port a lot of software (for example i will need mysql client library) or a graphic library like (nano-x).

did someone know a thread library which I can port?
it shouldn't have everything.
newlib doesn't have support for thread and also ucos-ii.

the problem with thread libraries is that they are extremely tighly coupled with the system that implements threads. Honnestly, i haven't investigated ucos-* systems, but if i were you, i'd be looking at where that system comes from (like BSD? QNX?), which other system with a thread library is the closest and hope that would mean it'd be the easiest to port ...
