Ned Deily <[email protected]> added the comment:
Issue6877 (and subsequent fixes in Issue8066) allows the Python readline module
to be built and linked with the OS X editline (libedit) library rather than
with the GNU readline library (which is not included with OS X). However, the
libedit included in versions of OS X prior to 10.5 is considered too broken to
use here.
By default, if you do not specify an --with-universal-archs other than "32-bit"
to configure or if you do not explicitly set MACOSX_DEPLOYMENT_TARGET to
another value, configure defaults to using "10.4" (or earlier) so the building
of the readline module is skipped. You can check this:
>>> from distutils.sysconfig import get_config_var
>>> get_config_var('MACOSX_DEPLOYMENT_TARGET')
'10.4'
(Whether this is the best default is another question.)
As it stands, to be able to build the readline module, either:
(1) supply the GNU readline library as a local library, or
(2) ensure you are building with a deployment target of at least 10.5. For
example:
./configure MACOSX_DEPLOYMENT_TARGET=10.6 ; make
Also note that option (2) is not available for 3.1.x since the changes to
support editline/libedit were not ported to it; they are, however, in 2.6.5,
2.7 (trunk), and 3.2 (py3k).
