# Makefile for zlib, derived from Makefile.dj2.
# Modified for mingw32 by C. Spieler, 6/16/98.
# Updated for zlib 1.2.x by Christian Spieler and Cosmin Truta, Mar-2003.
# Last updated: Mar 2012.
# Tested under Cygwin and MinGW.

# Copyright (C) 1995-2003 Jean-loup Gailly.
# For conditions of distribution and use, see copyright notice in zlib.h

# To compile, or to compile and test, type from the top level zlib directory:
#
#   make -fwin32/Makefile.gcc;  make test testdll -fwin32/Makefile.gcc
#
# To use the asm code, type:
#   cp contrib/asm?86/match.S ./match.S
#   make LOC=-DASMV OBJA=match.o -fwin32/Makefile.gcc
#
# To install libz.a, zconf.h and zlib.h in the system directories, type:
#
#   make install -fwin32/Makefile.gcc
#
# BINARY_PATH, INCLUDE_PATH and LIBRARY_PATH must be set.

# Note:
# If the platform is *not* MinGW (e.g. it is Cygwin or UWIN),
# the DLL name should be changed from "zlib1.dll".
