- # Sample makefile for rpng-x / rpng2-x / wpng using 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 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.)
