- # 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.)
