# Sample makefile for rpng-win / rpng2-win / wpng using mingw32-gcc and make.
# Greg Roelofs
# Last modified: 2 June 2007
#
# The programs built by this makefile are described in the book,
# "PNG: The Definitive Guide," by Greg Roelofs (O'Reilly and
# Associates, 1999). Go buy a copy, eh? Well, OK, it's not
# generally for sale anymore, but it's the thought that counts,
# right? (Hint: http://www.libpng.org/pub/png/book/ )
#
# Invoke this makefile from a DOS-prompt window via:
#
# make -f Makefile.mingw32
#
# This makefile assumes libpng and zlib have already been built or downloaded
# and are in subdirectories at the same level as the current subdirectory
# (as indicated by the PNGDIR and ZDIR macros below). It makes no assumptions
# at all about the mingw32 installation tree (W32DIR). Edit as appropriate.
#
# Note that the names of the dynamic and static libpng and zlib libraries
# used below may change in later releases of the libraries. This makefile
# builds both statically and dynamically linked executables by default.
# (You need only one set, but for testing it can be handy to have both.)
