| 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.)
