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.) |
