# Script for building the _ssl module for Windows. # Uses Perl to setup the OpenSSL environment correctly # and build OpenSSL, then invokes a simple nmake session # for _ssl.pyd itself. # 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 PC/VC6 directory. # # it should configure and build SSL, then build the ssl Python extension # 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.
