# "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.)

|
|
|
|
|
# "c:\windows\command.com /e:4096" as the program command line and set the
|
|
|
|
|
# working directory to this directory. Then double-click to open the new

|
|
|
# DOS-prompt window with a bigger environment and retry the commands above.

# This makefile assumes libpng and zlib have already been built or downloaded
|

|
# and are in subdirectories at the same level as the current subdirectory
|

|
# (as indicated by the PNGPATH and ZPATH macros below). Edit as appropriate.

# Note that the names of the dynamic and static libpng and zlib libraries
|
|
|

|
# used below may change in later releases of the libraries. This makefile
|

# builds statically linked executables, but that can be changed by uncom-
|
|
|
|
|
# menting the appropriate PNGLIB and ZLIB lines.
