So part of the question is, in order to get Wine to function properly on Cygwin, what is the right threading approach to take? Am I right in thinking that the current code wouldn't work on Cygwin?
I say, let's get the compiling and linking working, and then worry about actually running it... :)
As far as I can see the only places get_thread_context and set_thread_context are used is in scheduler/thread.c, to implement WINAPI GetThreadContext and SetThreadContext
So actually a first approximation for [sg]et_thread_context for Cygwin would be one that does nothing. Then we can try submitting patches to Cygwin (Approach 2), so that other apps can make use of ptrace, if necessary.
OK, done that. So now wineserver.exe actually links :-) And it runs too! However can't yet see whether its going to do anything as in order to actually run programs it looks like we need tolink miscemu/main.c Problem here being that it wants to link with ntdll, which doesn't build yet. That still needs a lot more work... In the mean time a very simple patch that does nothing for context_i386.c is below in case anyone else wants to try... David
