2# Script for building the _ssl and _hashlib modules for Windows.
3# Uses Perl to setup the OpenSSL environment correctly
4# and build OpenSSL, then invokes a simple nmake session
5# for the actual _ssl.pyd and _hashlib.pyd DLLs.
6
7# THEORETICALLY, you can:
8# * Unpack the latest SSL release one level above your main Python source
9# directory. It is likely you will already find the zlib library and
10# any other external packages there.
11# * Install ActivePerl and ensure it is somewhere on your path.
12# * Run this script from the PCBuild directory.
13#
14# it should configure and build SSL, then build the _ssl and _hashlib
15# Python extensions without intervention.
16
17# Modified by Christian Heimes
18# Now this script supports pre-generated makefiles and assembly files.
19# Developers don't need an installation of Perl anymore to build Python. A svn
20# checkout from our svn repository is enough.
21#
22# In Order to create the files in the case of an update you still need Perl.
23# Run build_ssl in this order:
24# python.exe build_ssl.py Release x64
25# python.exe build_ssl.py Release Win32
