1 # Sample makefile for rpng-win / rpng2-win / wpng using mingw32-gcc and make.
2 # Greg Roelofs
3 # Last modified: 2 June 2007
4 #
5 # The programs built by this makefile are described in the book,
6 # "PNG: The Definitive Guide," by Greg Roelofs (O'Reilly and
7 # Associates, 1999). Go buy a copy, eh? Well, OK, it's not
8 # generally for sale anymore, but it's the thought that counts,
9 # right? (Hint: http://www.libpng.org/pub/png/book/ )
10 #
11 # Invoke this makefile from a DOS-prompt window via:
12 #
13 # make -f Makefile.mingw32
14 #
15 # This makefile assumes libpng and zlib have already been built or downloaded
16 # and are in subdirectories at the same level as the current subdirectory
17 # (as indicated by the PNGDIR and ZDIR macros below). It makes no assumptions
18 # at all about the mingw32 installation tree (W32DIR). Edit as appropriate.
19 #
20 # Note that the names of the dynamic and static libpng and zlib libraries
21 # used below may change in later releases of the libraries. This makefile
22 # builds both statically and dynamically linked executables by default.
23 # (You need only one set, but for testing it can be handy to have both.)
