# 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.)
