# Sample makefile for rpng-win / rpng2-win / wpng using MSVC and NMAKE.

# 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 DOS prompt window via:

#

# %devstudio%\vc\bin\vcvars32.bat

# nmake -nologo -f Makefile.w32

#

# where %devstudio% is the installation directory for MSVC / DevStudio. If

# you get "environment out of space" errors, create a desktop shortcut with

# "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.

# maintenance ---------------------------------------------------------------

clean:

# ideally we could just do this:

# $(RM) $(EXES) $(ROBJS) $(ROBJS2) $(WOBJS)

# ...but the Windows "DEL" command is none too bright, so:

$(RM) r*$(E)

$(RM) w*$(E)

$(RM) r*$(O)

$(RM) w*$(O)
