I'm trying to find out which version of glibc Python is using.
I need a fix that went into glibc 2.10 back in 2009.
(http://udrepper.livejournal.com/20948.html)
So I try the recommended way to do this, on a CentOS server:
/usr/local/bin/python2.7
Python 2.7.2 (default, Jan 18 2012, 10:47:23)
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> platform.libc_ver()
('glibc', '2.3')
This is telling me that the Python distribution built in 2012,
with a version of GCC released April 16, 2011, is using
glibc 2.3, released in October 2002. That can't be right.
I tried this on a different Linux machine, a desktop running
Ubuntu 12.04 LTS:
Python 2.7.3 (defualt, April 10 2013, 06:20:15)
[GCC 4.6.3] on linux2
('glibc', '2.7')
That version of glibc is from October 2007.
Where are these ancient versions coming from? They're
way out of sync with the GCC version.
