Got undefined symbol: _PyUnicodeUCS2_AsDefaultEncodedString on OpenSuSE 11.1

[Alejandro Valdez]

Hello Mark, thank you a lot for your hints, I compiled python using
the --enable-unicode=ucs4 parameter in configure and I could
successfully install setuptools (Anyway I'm a little suspicious about
my compiled binaries...).

You are right about the environment variables, I have set PYTHONPATH
and PYTHONHOME to:
PYTHONPATH=$HOME/python/lib/python2.6/site-packages
PYTHONHOME=$HOME/python

The compiler issued some warnings, two of them (related to Unicode)
called my attention:

In file included from Python/formatter_unicode.c:13:
Python/../Objects/stringlib/formatter.h: In function
‘unknown_presentation_type’:
Python/../Objects/stringlib/formatter.h:35: warning: format ‘%c’
expects type ‘int’, but argument 3 has type ‘Py_UNICODE’

Should I ignore them?




Other warning messages:
