# Sample makefile for rpng-x / rpng2-x / wpng using gcc and make.

# 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? Buy some for friends
|
|
# and family, too. (Not that this is a blatant plug or anything.)
|
|
#
|
|
# 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 both installed in /usr/local/{include,lib} (as indicated by the
|
|
# PNGPATH and ZPATH macros below). Edit as appropriate.
|
|
#
|
|
# This makefile builds statically linked executables (against libpng and zlib,
|
|
# that is), but that can be changed by uncommenting the appropriate PNGLIB and
|
|
# ZLIB lines.
