| # Sample makefile for rpng-win / rpng2-win / wpng using mingw32-gcc and make. |

| # 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.) |
