1 # Script for building the _ssl and _hashlib modules for Windows.
2 # Uses Perl to setup the OpenSSL environment correctly
3 # and build OpenSSL, then invokes a simple nmake session
4 # for the actual _ssl.pyd and _hashlib.pyd DLLs.
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.
13 # it should configure and build SSL, then build the _ssl and _hashlib
14 # Python extensions without intervention.
16 # Modified by Christian Heimes
17 # Now this script supports pre-generated makefiles and assembly files.
18 # Developers don't need an installation of Perl anymore to build Python. A svn
19 # checkout from our svn repository is enough.
21 # In Order to create the files in the case of an update you still need Perl.
22 # Run build_ssl in this order:
23 # python.exe build_ssl.py Release x64
24 # python.exe build_ssl.py Release Win32
