# Sample makefile for rpng-win / rpng2-win / wpng using mingw32-gcc and make.# 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:##	make -f Makefile.mingw32## 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 PNGDIR and ZDIR macros below).  It makes no assumptions# at all about the mingw32 installation tree (W32DIR).  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 both statically and dynamically linked executables by default.# (You need only one set, but for testing it can be handy to have both.)# macros --------------------------------------------------------------------#PNGDIR = ../..#		for libpng-x.y.z/contrib/gregbook buildsPNGDIR = ../libpng-win32PNGINC = -I$(PNGDIR)PNGLIBd = $(PNGDIR)/libpng.dll.a	# dynamically linkedPNGLIBs = $(PNGDIR)/libpng.a		# statically linked, local libpng#ZDIR = ../../../zlib-win32#	for libpng-x.y.z/contrib/gregbook buildsZDIR = ../zlib-win32ZINC = -I$(ZDIR)ZLIBd = $(ZDIR)/libzdll.aZLIBs = $(ZDIR)/libz.a# change this to be the path where mingw32 installs its stuff:W32DIR =#W32DIR = /usr/local/cross-tools/i386-mingw32msvcW32INC = -I$(W32DIR)/includeW32LIB = $(W32DIR)/lib/libuser32.a $(W32DIR)/lib/libgdi32.aCC = gcc#CC = i386-mingw32msvc-gcc #	e.g., Linux -> Win32 cross-compilationLD = $(CC)RM = rm -fCFLAGS = -O -Wall $(INCS) $(MINGW_CCFLAGS)# [note that -Wall is a gcc-specific compilation flag ("most warnings on")]# [-ansi, -pedantic and -W can also be used]LDFLAGS = $(MINGW_LDFLAGS)O = .oE = .exeINCS = $(PNGINC) $(ZINC) $(W32INC)RLIBSd = $(PNGLIBd) $(ZLIBd) $(W32LIB) -lmRLIBSs = $(PNGLIBs) $(ZLIBs) $(W32LIB) -lmWLIBSd = $(PNGLIBd) $(ZLIBd)WLIBSs = $(PNGLIBs) $(ZLIBs)RPNG   = rpng-winRPNG2  = rpng2-winWPNG   = wpngROBJSd  = $(RPNG)$(O) readpng.pic$(O)ROBJS2d = $(RPNG2)$(O) readpng2.pic$(O)WOBJSd  = $(WPNG)$(O) writepng.pic$(O)RPNGs  = $(RPNG)-staticRPNG2s = $(RPNG2)-staticWPNGs  = $(WPNG)-staticROBJSs  = $(RPNG)$(O) readpng$(O)ROBJS2s = $(RPNG2)$(O) readpng2$(O)WOBJSs  = $(WPNG)$(O) writepng$(O)STATIC_EXES  = $(RPNGs)$(E) $(RPNG2s)$(E) $(WPNGs)$(E)DYNAMIC_EXES = $(RPNG)$(E) $(RPNG2)$(E) $(WPNG)$(E)EXES = $(STATIC_EXES) $(DYNAMIC_EXES)# implicit make rules -------------------------------------------------------.c$(O):	$(CC) -c $(CFLAGS) $<%.pic$(O): %.c	$(CC) -c $(CFLAGS) -DPNG_BUILD_DLL -o $@ $<# dependencies --------------------------------------------------------------all:  $(EXES)$(RPNGs)$(E): $(ROBJSs)	$(LD) $(LDFLAGS) -o $@ $(ROBJSs) $(RLIBSs)$(RPNG)$(E): $(ROBJSd)	$(LD) $(LDFLAGS) -o $@ $(ROBJSd) $(RLIBSd)$(RPNG2s)$(E): $(ROBJS2s)	$(LD) $(LDFLAGS) -o $@ $(ROBJS2s) $(RLIBSs)$(RPNG2)$(E): $(ROBJS2d)	$(LD) $(LDFLAGS) -o $@ $(ROBJS2d) $(RLIBSd)$(WPNGs)$(E): $(WOBJSs)	$(LD) $(LDFLAGS) -o $@ $(WOBJSs) $(WLIBSs)$(WPNG)$(E): $(WOBJSd)	$(LD) $(LDFLAGS) -o $@ $(WOBJSd) $(WLIBSd)$(RPNG)$(O):	$(RPNG).c readpng.h$(RPNG2)$(O):	$(RPNG2).c readpng2.h$(WPNG)$(O):	$(WPNG).c writepng.hreadpng$(O) readpng.pic$(O):	readpng.c readpng.hreadpng2$(O) readpng2.pic$(O):	readpng2.c readpng2.hwritepng$(O) writepng.pic$(O):	writepng.c writepng.h# maintenance ---------------------------------------------------------------clean:	$(RM) $(EXES)	$(RM) $(ROBJSs) $(ROBJS2s) $(WOBJSs)	$(RM) $(ROBJSd) $(ROBJS2d) $(WOBJSd)
