PIL & Tk8.2

[Fred Fubar]

The big issue is not PIL by _tkinter. Here are my instructions for building
Tk8.2 compatible PIL (on NT 4.0 system with VC++ 6.0):

1) You need to generate a makefile or VC project file, since F.L. uses other
means. My recommendation is to get Ken Seehof's PyExtWizard
(http://starship.python.net/crew/seehof/PyExtWizard.html) and generate an
empty project called "PIL". Then delete the stdafx.* and PIL.cpp files from
this project and instead, add all the requisite files from the PIL 1.0
release (all *.c and *.h except coretest.c and except.c, as per the
instructions in the PIL release)

2) Edit the project settings (C++/Preprocessor/Include Directories) to put
the tcl/tk 8.2 include directory in the include search path.

3) Build PIL

Now you also have to build an 8.2 compatible version of _tkinter.pyd.

1) Go to the Python anonymous CVS repository (see
http://www.python.org/download/cvs.html for instructions) and look at the
post "r152" modifications to python/dist/src/Modules/_tkinter.c (revision
1.89 vc. 1.88) and tkappinit.c (rev. 1.7 vs. 1.6), which incorporate Dieter
Maurer's patches for tcl/tk 8.1 and 8.2 functionality). On Windows NT, the
comments in _tkinter.c, that the patch does not work on Tcl/Tk 8.2 seems to
be incorrect, so you want to change the line 491 from

#if TKMAJORMINOR == 8001

to

#if TKMAJORMINOR >= 8001

On other systems, YMMV.

2) Apply this patch to FixTk.py:

For UNIX builds, you can skip much of this and probably only need to make
the requisite mods of _tkinter.c, tkappinit.c, and FixTk.py.
