Thanks very much for you response, Roger!
I am sorry but I am not able to follow what you are saying. I am quite
new to linux installation world and it's possible that I am missing
pretty straightforward info.
Did you mean to say that Ubuntu does come pre-installed with 64-bit
Python? When I used the same command as you did, I see a 32-bit
version there. I am not sure how to get to 64-bit.
$ file /usr/bin/python2.6
/usr/bin/python2.6: ELF 32-bit LSB executable, Intel 80386, version 1
(SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15,
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
I also tried building Python on this machine by setting following
/configure --enable-universalsdk --with-universal-archs="64-bit"
But no luck. I am definitely missing something here. Could you please
explain how did you get a 64-bit version there? I am using ubuntu
