Hi, I have been working with the Tools/freeze/freeze.py etc. utilities in order to build a Python binary with part of the Python library built in. I found out you-all have been working on this. But AFAIK we are not there yet. I see that using freeze.py will create a binary Python with the libs included in the frozen module. But: 1) The "script" argument to freeze.py is not optional. Some module is always frozen with the name __main__ and so it is always executed when Python starts up. This makes it impossible to create a python15.dll (or python15.so) which is general-purpose. That is, a shared binary Python with libraries but not a main program built in. Since the Python interpreter and libs must use exactly the same version, it is useful to link them together. 2) There is only one frozen module allowed, so no further use of frozen modules is possible. The frozen feature has been devoted to the Python libraries. This makes it impossible to make a python15.dll which can be used with a variety of python.exe programs with further frozen modules. Unix translation: A python15.so shared library for use with further python main programs containing frozen modules. I have code which solves both problems. But perhaps I have not understood Tools/freeze, and there is already a way to do this? I see there is a function PyImport_ExtendInittab() in import.c which adds entries to the table of built-in modules, which is sort of analogous to (2), but that this function is unused. (My code uses a different method.) Please let me know what you think. Is this useful enough to be added to Python? Or is it already there? Jim Ahlstrom
