!!              m_Pid = execi(&Thread::runWrapper, 0, (char**)NULL,
m_Prio, m_Stack);

IRC, every method in C++ has an implicit parameter wich is the object itself;
that's why you can't cast it. Try the following (does someone have a nicer

Put runWrapper() outside the class:

int runWrapper(int, char **th) {
  ((Thread*)th)->Run();
  return 0;
}

in Start():

m_Pid = execi(runWrapper, 0, (char**)this, m_Prio, m_Stack);
