| 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? Well, OK, it's not |
| 8 | # generally for sale anymore, but it's the thought that counts, |
| 9 | # right? (Hint: http://www.libpng.org/pub/png/book/ ) |
| 10 | # |
| 11 | # Invoke this makefile from a shell prompt in the usual way; for example: |
| 12 | # |
| 13 | # make -f Makefile.unx |
| 14 | # |
| 15 | # This makefile assumes libpng and zlib have already been built or downloaded |
| 16 | # and are installed in /usr/local/{include,lib} or as otherwise indicated by |
| 17 | # the PNG* and Z* macros below. Edit as appropriate--choose only ONE each of |
| 18 | # the PNGINC, PNGLIBd, PNGLIBs, ZINC, ZLIBd and ZLIBs lines. |
| 19 | # |
| 20 | # This makefile builds both dynamically and statically linked executables |
| 21 | # (against libpng and zlib, that is), but that can be changed by modifying |
| 22 | # the "EXES =" line. (You need only one set, but for testing it can be handy |
| 23 | # to have both.) |
