| # 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? 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 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 installed in /usr/local/{include,lib} or as otherwise indicated by |
| # the PNG* and Z* macros below. Edit as appropriate--choose only ONE each of |
| # the PNGINC, PNGLIBd, PNGLIBs, ZINC, ZLIBd and ZLIBs lines. |
| # |
| # This makefile builds both dynamically and statically linked executables |
| # (against libpng and zlib, that is), but that can be changed by modifying |
| # the "EXES =" line. (You need only one set, but for testing it can be handy |
| # to have both.) |
