1 # Sample makefile for rpng-x / rpng2-x / wpng using gcc and make.

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? Buy some for friends
8 # and family, too. (Not that this is a blatant plug or anything.)
10 # Invoke this makefile from a shell prompt in the usual way; for example:
12 # make -f Makefile.unx
14 # This makefile assumes libpng and zlib have already been built or downloaded
15 # and are both installed in /usr/local/{include,lib} (as indicated by the
16 # PNG* and Z* macros below). Edit as appropriate--choose only ONE each of
17 # the PNGINC, PNGLIB, ZINC and ZLIB lines.
19 # This makefile builds statically linked executables (against libpng and zlib,
20 # that is), but that can be changed by uncommenting the appropriate PNGLIB and
24 # macros --------------------------------------------------------------------
