# 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. A svn
|
|
# checkout from our svn repository is enough.
