New submission from Attila Soki <atiw...@gmx.net>:
i trying to compile Python 2.6.1 from scratch on Mac OS X Server (ppc).
After configure/make/make install i test the compiled python with
the followig file (t.py) (example from
http://docs.python.org/library/urllib.html):
Contents of /tmp/t.py:
-------------
import urllib
params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0})
f = urllib.urlopen("http://www.musi-cal.com/cgi-bin/query";, params)
print f.read()
-------------
and i get this error:
python /tmp/t.py
Traceback (most recent call last):
File "/tmp/t.py", line 3, in <module>
f = urllib.urlopen("http://www.musi-cal.com/cgi-bin/query";, params)

Both test fails on my PPC Mac and runs without error on my Intel MacBook

I recompiled Python-2.6.1 with MACOSX_DEPLOYMENT_TARGET=10.3, but no
change..
I updated developertools to xcode312_2621, no change..
Btw.. Python-2.5.4 compiled from scratch works fine.
I dig a bit deeper with otool and discover some differences:
Intel MacOS.so: Carbon, libSystem.B.dylib, CoreServices,
ApplicationServices
PPC MacOS.so: Carbon, libmx.A.dylib, libSystem.B.dylib
Intel _ctypes.so: libSystem.B.dylib
PPC _ctypes.so: libmx.A.dylib, libSystem.B.dylib

How i compiled it:
export MACOSX_DEPLOYMENT_TARGET=10.5
configure --prefix=/usr/local/test/python
make
make install
How i test:
export
PYTHONPATH=/usr/local/test/python:/usr/local/test/python/lib/python2.6/site-packages
/usr/local/test/python/bin/ is in the PATH
python /tmp/t.py
