Using Tools/freeze.py on AIX -- having problems

P: n/a
I have a python script that I need to freeze on AIX 5.1 (customer has
AIX and does not want to install Python). The python script is pretty
simple (the only things it imports are sys and socket).

The README file in the Tools/freeze directory of the Python-2.4.4
distribution says the following (and many other things):

Previous versions of Freeze used a pretty simple-minded algorithm to
find the modules that your program uses, essentially searching for
lines starting with the word "import". It was pretty easy to trick it
into making mistakes, either missing valid import statements, or
mistaking string literals (e.g. doc strings) for import statements.

This has been remedied: Freeze now uses the regular Python parser to
parse the program (and all its modules) and scans the generated byte
code for IMPORT instructions. It may still be confused -- it will not
know about calls to the __import__ built-in function, or about import
statements constructed on the fly and executed using the 'exec'
statement, and it will consider import statements even when they are
unreachable (e.g. "if 0: import foobar").

This new version of Freeze also knows about Python's new package
import mechanism, and uses exactly the same rules to find imported
modules and packages. One exception: if you write 'from package
import *', Python will look into the __all__ variable of the package
to determine which modules are to be imported, while Freeze will do a
directory listing.

One tricky issue: Freeze assumes that the Python interpreter and
environment you're using to run Freeze is the same one that would be
used to run your program, which should also be the same whose sources
and installed files you will learn about in the next section. In
particular, your PYTHONPATH setting should be the same as for running
your program locally. (Tip: if the program doesn't run when you type
"python hello.py" there's little chance of getting the frozen version
to run.)

I have installed Python-2.4.4 on AIX using the procedure:

(logged in as root)
../configure --disable-ipv6 --disable-shared
make
make test
make install

The compiler being used during this process is: VisualAge C++
Professional / C for AIX Compiler, Version 6.

Python seems to install correctly for the most part ("make test" gives
a few messages about things that are not quite right (3 failed tests
(test_mmap, test_pty, & test_resource) and 2 unexpectedly skipped
(test_curses & test_largefile)), but nothing major (all the normal
stuff, including test_socket and test_sys, passed)). Also, the
unfrozen version of the script seems to run properly on the Python
interpreter after installation.

After this paragraph follows the output from the freeze. The biggest
problem is the part at the bottom "Warning: unknown modules remain:".
Neither of the suggestions in the README file in the Tools/freeze
directory about this warning message have proven helpful.

generating table of frozen modules
Warning: unknown modules remain: _locale _random _socket array binascii

Now run "make" in xfer to build the target: xfer

After running make, here is the result of trying to execute the frozen
script:

# ./xfer
Traceback (most recent call last):
File "xfer.py", line 2, in ?

Any insight you can provide in regards to this problem would be greatly
appreciated !

Thanks !!!

Don't worry about these.

There's this note in freeze.py:

"""
The script should not use modules provided only as shared libraries;
if it does, the resulting binary is not self-contained.
"""

I don't really remember much about freeze. IIRC, you will also need to
copy the extension modules (I left them in above) in addition to
'xfer'. Try copying them into the same directory. You might need to
set LIBPATH=. (or whatever the env't var is). On most Unixes, the
env't var is LD_LIBRARY_PATH, but I recall AIX being different.

If you want, you can just copy all the files from lib-dynload along
with 'xfer'.
