From d5537d071cc2acada7220431a0eea5931c2e8a2d Mon Sep 17 00:00:00 2001 From: "doko@ubuntu.com" Date: Thu, 21 Mar 2013 13:21:49 -0700 Subject: [PATCH] - Issue #16754: Fix the incorrect shared library extension on linux. Introduce two makefile macros SHLIB_SUFFIX and EXT_SUFFIX. SO now has the value of SHLIB_SUFFIX again (as in 2.x and 3.1). The SO macro is removed in 3.4. --- Doc/whatsnew/3.2.rst | 4 +- Lib/distutils/command/build_ext.py | 6 +-- Lib/distutils/sysconfig.py | 8 ++-- Lib/distutils/tests/test_build_ext.py | 8 ++-- Lib/distutils/tests/test_install.py | 2 +- Lib/sysconfig.py | 1 + Makefile.pre.in | 11 ++++- Misc/NEWS | 4 ++ Misc/python-config.in | 2 +- configure | 66 ++++++++++++--------------- configure.ac | 59 +++++++++++------------- pyconfig.h.in | 3 -- setup.py | 13 ++---- 13 files changed, 88 insertions(+), 99 deletions(-) diff --git a/Doc/whatsnew/3.2.rst b/Doc/whatsnew/3.2.rst index 09640f6d6f3..47d477f8c01 100644 --- a/Doc/whatsnew/3.2.rst +++ b/Doc/whatsnew/3.2.rst @@ -368,9 +368,9 @@ In Python itself, the tags are accessible from functions in the :mod:`sysconfig` module:: >>> import sysconfig -
