| # Sample makefile for rpng-x / rpng2-x / wpng using 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? Buy some for friends |
| # and family, too. (Not that this is a blatant plug or anything.) |
| # |
| # Invoke this makefile from a shell prompt in the usual way; for example: |
| # |
| # make -f makefile.unx |
| # |
| # This makefile assumes libpng and zlib have already been built or downloaded |
| # and are both installed in /usr/local/{include,lib} (as indicated by the |
| # PNGPATH and ZPATH macros below). Edit as appropriate. |
| # |
| # This makefile builds statically linked executables (against libpng and zlib, |
| # that is), but that can be changed by uncommenting the appropriate PNGLIB and |
| # ZLIB lines. |
