1# Sample makefile for rpng-win / rpng2-win / wpng using mingw32-gcc and make. 2# Greg Roelofs 3# Last modified: 2 June 2007 4# 5# The programs built by this makefile are described in the book, 6# "PNG: The Definitive Guide," by Greg Roelofs (O'Reilly and 7# Associates, 1999). Go buy a copy, eh? Well, OK, it's not 8# generally for sale anymore, but it's the thought that counts, 9# right? (Hint: http://www.libpng.org/pub/png/book/ ) 10# 11# Invoke this makefile from a DOS-prompt window via: 12# 13# make -f Makefile.mingw32 14# 15# This makefile assumes libpng and zlib have already been built or downloaded 16# and are in subdirectories at the same level as the current subdirectory 17# (as indicated by the PNGDIR and ZDIR macros below). It makes no assumptions 18# at all about the mingw32 installation tree (W32DIR). Edit as appropriate. 19# 20# Note that the names of the dynamic and static libpng and zlib libraries 21# used below may change in later releases of the libraries. This makefile 22# builds both statically and dynamically linked executables by default. 23# (You need only one set, but for testing it can be handy to have both.) 24 25 26# macros -------------------------------------------------------------------- 27 28#PNGDIR = ../..# for libpng-x.y.z/contrib/gregbook builds 29PNGDIR = ../libpng-win32 30PNGINC = -I$(PNGDIR) 31PNGLIBd = $(PNGDIR)/libpng.dll.a # dynamically linked 32PNGLIBs = $(PNGDIR)/libpng.a # statically linked, local libpng 33 34#ZDIR = ../../../zlib-win32# for libpng-x.y.z/contrib/gregbook builds 35ZDIR = ../zlib-win32 36ZINC = -I$(ZDIR) 37ZLIBd = $(ZDIR)/libzdll.a 38ZLIBs = $(ZDIR)/libz.a 39 40# change this to be the path where mingw32 installs its stuff: 41W32DIR = 42#W32DIR = /usr/local/cross-tools/i386-mingw32msvc 43W32INC = -I$(W32DIR)/include 44W32LIB = $(W32DIR)/lib/libuser32.a $(W32DIR)/lib/libgdi32.a 45 46CC = gcc 47#CC = i386-mingw32msvc-gcc # e.g., Linux -> Win32 cross-compilation 48LD = $(CC) 49RM = rm -f 50CPPFLAGS = $(INCS) 51CFLAGS = -O -Wall $(MINGW_CCFLAGS) 52# [note that -Wall is a gcc-specific compilation flag ("most warnings on")] 53# [-ansi, -pedantic and -W can also be used] 54LDFLAGS = $(MINGW_LDFLAGS) 55O = .o 56E = .exe 57 58INCS = $(PNGINC) $(ZINC) $(W32INC) 59RLIBSd = $(PNGLIBd) $(ZLIBd) $(W32LIB) -lm 60RLIBSs = $(PNGLIBs) $(ZLIBs) $(W32LIB) -lm 61WLIBSd = $(PNGLIBd) $(ZLIBd) 62WLIBSs = $(PNGLIBs) $(ZLIBs) 63 64RPNG = rpng-win 65RPNG2 = rpng2-win 66WPNG = wpng 67 68ROBJSd = $(RPNG)$(O) readpng.pic$(O) 69ROBJS2d = $(RPNG2)$(O) readpng2.pic$(O) 70WOBJSd = $(WPNG)$(O) writepng.pic$(O) 71 72RPNGs = $(RPNG)-static 73RPNG2s = $(RPNG2)-static 74WPNGs = $(WPNG)-static 75 76ROBJSs = $(RPNG)$(O) readpng$(O) 77ROBJS2s = $(RPNG2)$(O) readpng2$(O) 78WOBJSs = $(WPNG)$(O) writepng$(O) 79 80STATIC_EXES = $(RPNGs)$(E) $(RPNG2s)$(E) $(WPNGs)$(E) 81DYNAMIC_EXES = $(RPNG)$(E) $(RPNG2)$(E) $(WPNG)$(E) 82 83EXES = $(STATIC_EXES) $(DYNAMIC_EXES) 84 85 86# implicit make rules ------------------------------------------------------- 87 88.c$(O): 89 $(CC) -c $(CPPFLAGS) $(CFLAGS) $< 90 91%.pic$(O): %.c 92 $(CC) -c $(CPPFLAGS) $(CFLAGS) -DPNG_BUILD_DLL -o $@ $< 93 94 95# dependencies -------------------------------------------------------------- 96 97all: $(EXES) 98 99$(RPNGs)$(E): $(ROBJSs) 100 $(LD) $(LDFLAGS) -o $@ $(ROBJSs) $(RLIBSs) 101 102$(RPNG)$(E): $(ROBJSd) 103 $(LD) $(LDFLAGS) -o $@ $(ROBJSd) $(RLIBSd) 104 105$(RPNG2s)$(E): $(ROBJS2s) 106 $(LD) $(LDFLAGS) -o $@ $(ROBJS2s) $(RLIBSs) 107 108$(RPNG2)$(E): $(ROBJS2d) 109 $(LD) $(LDFLAGS) -o $@ $(ROBJS2d) $(RLIBSd) 110 111$(WPNGs)$(E): $(WOBJSs) 112 $(LD) $(LDFLAGS) -o $@ $(WOBJSs) $(WLIBSs) 113 114$(WPNG)$(E): $(WOBJSd) 115 $(LD) $(LDFLAGS) -o $@ $(WOBJSd) $(WLIBSd) 116 117$(RPNG)$(O): $(RPNG).c readpng.h 118$(RPNG2)$(O): $(RPNG2).c readpng2.h 119$(WPNG)$(O): $(WPNG).c writepng.h 120 121readpng$(O) readpng.pic$(O): readpng.c readpng.h 122readpng2$(O) readpng2.pic$(O): readpng2.c readpng2.h 123writepng$(O) writepng.pic$(O): writepng.c writepng.h 124 125 126# maintenance --------------------------------------------------------------- 127 128clean: 129 $(RM) $(EXES) 130 $(RM) $(ROBJSs) $(ROBJS2s) $(WOBJSs) 131 $(RM) $(ROBJSd) $(ROBJS2d) $(WOBJSd) 132
