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. 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 and _hashlib 14# Python extensions without intervention. 15 16import os, sys, re 17 18# Find all "foo.exe" files on the PATH. 19def find_all_on_path(filename, extras = None): 20 entries = os.environ["PATH"].split(os.pathsep) 21 ret = [] 22 for p in entries: 23 fname = os.path.abspath(os.path.join(p, filename)) 24 if os.path.isfile(fname) and fname not in ret: 25 ret.append(fname) 26 if extras: 27 for p in extras: 28 fname = os.path.abspath(os.path.join(p, filename)) 29 if os.path.isfile(fname) and fname not in ret: 30 ret.append(fname) 31 return ret 32 33# Find a suitable Perl installation for OpenSSL. 34# cygwin perl does *not* work.
