Mark Hammondf229f9f2002-12-03 05:47:26 +00001# Script for building the _ssl module for Windows.
2# Uses Perl to setup the OpenSSL environment correctly
3# and build OpenSSL, then invokes a simple nmake session
4# for _ssl.pyd itself.
5
6# THEORETICALLY, you can:
7# * Unpack the latest SSL release one level above your main Python source
8# directory. It is likely you will already find the zlib library and
9# any other external packages there.
10# * Install ActivePerl and ensure it is somewhere on your path.
11# * Run this script from the PCBuild directory.
12#
13# it should configure and build SSL, then build the ssl Python extension
14# without intervention.
