# MSVC/NMAKE makefile for pngquant.

# 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 zlib has already been built or downloaded and is in
# a subdirectory at the same level as the current subdirectory (as indicated
# by the ZPATH macro below).  Edit as appropriate.
#
# Note that the names of the dynamic and static zlib libraries used below may
# change in later releases of the library.  This makefile builds statically
# linked executables, but that can be changed by uncommenting the appropriate
# ZLIB lines.

# dependencies --------------------------------------------------------------

all:  $(EXES)

# setargv.obj expands wildcards and is included as part of MSVC; may be called
# "wildargs.obj" (or similar) for Borland or Watcom compilers

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

clean:
#	ideally we could just do this:
#	$(RM) $(EXES) $(ROBJS) $(ROBJS2) $(WOBJS)
#	...but the Windows "DEL" command is none too bright, so:
	$(RM) $(PROG)$(E)
	$(RM) $(PROG)$(O)
	$(RM) rwpng$(O)
