[Tutor] Compile

[Max M. Stalnaker]

>

David said it well.  But maybe some more details on the state of the art are acceptable.  As David said, the purpose of freezing is to have a single executable.  This works on Unix, but not quite on Win.  Here are problems as I see them, and I am definitely subject to correction:

1) shared libaries do not freeze.  These are sort-of-dll's and sit in pyd files.  But they could be compiled statically.  Then there are dlls.
2) winall is probably dependent on some MFC stuff and would need to be rewritten in places to port to an alternative compiler.  Borland is an exception, since they licensed MFC at one point, but no one in the community is providing support for that compiler.
3) tkinter does not freeze on win platforms

If you were to solve any one of the three items then it would be a significant contribution to the community.  But I think you need msvc++ 6.0 around to solve these problems, even if only as a reference compiler.

The cgipython project does not have win ports yet and item 1 is relevant there.  If you get msvc++ 6.0 and read every scrap of doc you can find, you will eventually be faced with item 1 within the confines of the existing cgipython project.  This would be a reasonable project.  I think your enthusiasm is carrying you in the direction of unreasonable projects.
