# Simple Makefile.w32 for stunnel.exe by Michal Trojnara 1998-2007
#
# Modified by Brian Hatch  (bri@stunnel.org)
# 20101030 pdelaage:
# + multi-HOST management (if used on Windows host or Linux Host)
# + lack of gnu-win32 (rm) detection
# note: rm is used INTERNALLY by gcc for deletion if intermediate files.

# This makefile is only tested on the mingw compiler.  Mingw can successfully
# compile both openssl and stunnel.  If you want to use another compiler, give
# it a shot, and tell us how it went.

# pdelaage : THIS makefile can be used with mingw-make on Windows or gnu make
# on Linux, to produce the Win32 version of stunnel (target is win32).  It
# requires, on Windows, the use of gnu-win32 tools: rm, mkdir, rmdir that
# manages files and dirs BOTH on linux and Windows with / as path separator.
# Note: Native windows equivalent, del and mkdir/rmdir, badly manage / and \,
# so they cannot be used here.
# On Windows host, download:
# http://gnuwin32.sourceforge.net/downlinks/coreutils.php
# if you have forgotten this, this makefile will remind you...
 
# Modify this to point to your actual openssl compile directory
# (You did already compile openssl, didn't you???)
SSLDIR=../../openssl-0.9.8zg

# For mingw compiled openssl
SSLINC=$(SSLDIR)/outinc
SSLLIBS=-L$(SSLDIR)/out -leay32 -lssl32

# For MSVC compiled openssl
#SSLINC=$(SSLDIR)/inc32
#SSLLIBS=-L$(SSLDIR)/out32dll -lssleay32 -llibeay32

# c:\, backslash is not correctly recognized by mingw32-make, produces some
# "missing separator" issue.
# pdelaage: simple trick to detect if we are using mingw-gcc on a Windows host,
# or on a linux host.  windir is a system environment variable on windows NT
# and above, and then redefine some macros.
# note: ifdef is !IFDEF in MS nmake or Borland make.
#       $(info is !MESSAGE in MS nmake or Borland make.
