# Sample makefile for rpng-win / rpng2-win / wpng using MSVC and NMAKE.
# Greg Roelofs
# Last modified: 2 June 2007
#
# 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)
