# Script for preparing OpenSSL for building on Windows.
|
|
# Uses Perl to create nmake makefiles and otherwise prepare the way
|
|
# for building on 32 or 64 bit platforms.
|
|
|
|
# Script originally authored by Mark Hammond.

# Major revisions by:

|
# THEORETICALLY, you can:
|
|
# * Unpack the latest OpenSSL release where $(opensslDir) in
|
|
# PCbuild\pyproject.props expects it to be.
|
|
# * Install ActivePerl and ensure it is somewhere on your path.
|
|
# * Run this script with the OpenSSL source dir as the only argument.
|
|
#
|
|
# it should configure OpenSSL such that it is ready to be built by
|
|
# ssl.vcxproj on 32 or 64 bit platforms.
