[Py2exe-users] Re: py2exe for making .exe's that work when Python is installed?

The use would be to have something small that worked like ordinay exe, and consisted of only one file, unlike the output of exemaker.

I wonder to know why for it needed for you. For me is enough to write
simple batch launcher file.

I'm slightly hacks exemaker and rewrite its internal python ineraction
mechanism. So if you have working win32 compiler (Borland C++5.5 or MS
Toolkit 2003 -- both are free to downloads) installed on your machine I
can give you some hints:

You need include your main script as global const str into your program
source and use PyRun_SimpleString from Python C/API instead of Py_Main
as usual exemaker does for run script as string in your custom exe. But
you need to recompile exe each time. I suppose it's slightly not ideal
solution and not completely fit your needs.

I think it's better to store script as exe-resource that could be linked
to modified exemaker without recompiling it, but at this moment I not
playing with it. If someone want to help -- I can rewrite my exemaker
modification.

If you wish to bundling into exe all needed library that your python
program needs to work (like py2exe does) you should to build your exe
always against specified python dll, because py2exe store python
compiled bytecodes that depends on version of python (pyc for 2.4 won't
work with python23.dll). That's one important reason why py2exe always
bundle into produced exe pythonXX.dll.
