No - This variable is defined in module sysconfig if your python was
built with --enable-shared. For instance, with 7.2-shared:
% python-2.7-shared
>>> from distutils import sysconfig
>>> sysconfig.get_config_var("Py_ENABLE_SHARED")
1
Whereas with the static version:
% python-2.7-static
>>> from distutils import sysconfig
>>> sysconfig.get_config_var("Py_ENABLE_SHARED")
0
Surprisingly, the system python installed on my ubuntu machine
returns 0 for Py_ENABLE_SHARED, even though I definitely have
the shared version of libpython there. But at the same time,
I do have both archive and dso installed at both <prefix>/lib
and <prefix>/lib/python-<version>/config...
That's why, I think, it ends up working for me, even though it
seems that the python that is distributed with ubuntu is statically
linked.
