# Script for building the _ssl and _hashlib modules for Windows.
|
|
# Uses Perl to setup the OpenSSL environment correctly
|
|
# and build OpenSSL, then invokes a simple nmake session
|
|
# for the actual _ssl.pyd and _hashlib.pyd DLLs.
|
|
|
|
# THEORETICALLY, you can:
|
|
# * Unpack the latest SSL release one level above your main Python source
|
|
# directory. It is likely you will already find the zlib library and
|
|
# any other external packages there.
|
|
# * Install ActivePerl and ensure it is somewhere on your path.
|
|
# * Run this script from the PCBuild directory.
|
|
#
|
|
# it should configure and build SSL, then build the _ssl and _hashlib
|
|
# Python extensions without intervention.
|
|
|
|
# Modified by Christian Heimes
|
|
# Now this script supports pre-generated makefiles and assembly files.
|
|
# Developers don't need an installation of Perl anymore to build Python. A svn
|
|
# checkout from our svn repository is enough.
|
|
#
|
|
# In Order to create the files in the case of an update you still need Perl.
|
|
# Run build_ssl in this order:
|
|
# python.exe build_ssl.py Release x64
|
|
# python.exe build_ssl.py Release Win32
