# This Makefile builds the user-mode component
# of OpenVPN for WIN32 in the MinGW environment.
#
# Build Dependencies:
#	mingw		(GNU C compiler for windows)
#	msys		(GNU utilities and shell for windows)
#	OpenSSL		(SSL/TLS/crypto library)
#	LZO		(real-time compression library)
#       Dmalloc         (debugging only)
#
# Targets:
#	static -- link statically with OpenSSL
#       dynamic -- link dynamically with OpenSSL
#       dmalloc -- enable memory debugging using the dmalloc library 
#
# Note that LZO is always linked statically.
#
# To build openssl-0.9.7d, remember to edit ms\mw.bat
# adding '--win32' flag to make command:
#
#   make --win32 -f ms/mingw32.mak
#
# Now cd to top level openssl directory in a Windows
# command-prompt window, and type:
#
#   ms\mw
#
# See additional .bat scripts in install-win32 for OpenSSL
# build setup.
#
# If you are building with dmalloc debugging support
# see windbg.h for additional dmalloc notes.
