Re: ?? warning: ANSI C++ forbids implicit conversion from `void *' in argument passing

[Michael Mitton <michael cs millersville edu>]

The & in front of your function name is the problem.  Try

{
  pthread_t thread;

  pthread_create(&thread, NULL, (void *) doSimulation, NULL);
}

if you declare doSimulation as a void * (ie void *doSimulation(...)) you
can even drop the type cast.
