Summary: _tkinter.c won't build w/o threads?

Initial Comment:
I'm out of my area of expertice here trying to build python on Windows using cygwin and trying to use Tcl/Tk 8.4.2, but...

Anyway, it looks like I can't compile _tkinter.c unless I've configured python to use threads and I didn't because the main python README says not to with cygwin.

For example, tcl_lock is used in many places in _tkinter.c but it is only defined when WITH_THREAD is defined.

And there's no Sleep() function when WITH_THREADS is off, and that's used in WaitForMainLoop().

And in Tkapp_New() there's a call to PyThread_free_lock() that isn't inside an #ifdef WITH_THREAD block.

At the time, I needed 2.3a2. However, I was able to use a pre-built version for Windows and replace the included Tcl/Tk with 8.4.2. So, I'm good for now.

Is it really the case that you need to build Python with threads in order to build Tkinter? Why bother with all those #ifdef WITH_THREAD in _tkinter.c if building w/o threads isn't an option? Once I added them in, everything compiled and using Tkinter didn't give me any errors. It didn't give me any widgets on screen either, but I don't think that was related. :-)

Take care.

nnorwitz> Jason, can you help with this?

Yes. The short answer is I have been meaning to
update the official Python README. I guess that
I can't procrastinate anymore...

Do you really need to build CVS? Or, will the pre-built
Cygwin Python 2.2.2 suffice?

Well, that's simple the "main python README" is wrong.
See above. :,)

If _tkinter requires threads under other Unixes, then I
think that updating the official Python README is
sufficient. Do others agree?
