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 50CFLAGS = -O -Wall $(INCS) $(MINGW_CCFLAGS) 51# [note that -Wall is a gcc-specific compilation flag ("most warnings on")] 52# [-ansi, -pedantic and -W can also be used] 53LDFLAGS = $(MINGW_LDFLAGS) 54O = .o 55E = .exe 56 57INCS = $(PNGINC) $(ZINC) $(W32INC) 58RLIBSd = $(PNGLIBd) $(ZLIBd) $(W32LIB) -lm 59RLIBSs = $(PNGLIBs) $(ZLIBs) $(W32LIB) -lm 60WLIBSd = $(PNGLIBd) $(ZLIBd) 61WLIBSs = $(PNGLIBs) $(ZLIBs) 62 63RPNG = rpng-win 64RPNG2 = rpng2-win 65WPNG = wpng 66 67ROBJSd = $(RPNG)$(O) readpng.pic$(O) 68ROBJS2d = $(RPNG2)$(O) readpng2.pic$(O) 69WOBJSd = $(WPNG)$(O) writepng.pic$(O) 70 71RPNGs = $(RPNG)-static 72RPNG2s = $(RPNG2)-static 73WPNGs = $(WPNG)-static 74 75ROBJSs = $(RPNG)$(O) readpng$(O) 76ROBJS2s = $(RPNG2)$(O) readpng2$(O) 77WOBJSs = $(WPNG)$(O) writepng$(O) 78 79STATIC_EXES = $(RPNGs)$(E) $(RPNG2s)$(E) $(WPNGs)$(E) 80DYNAMIC_EXES = $(RPNG)$(E) $(RPNG2)$(E) $(WPNG)$(E) 81 82EXES = $(STATIC_EXES) $(DYNAMIC_EXES) 83 84 85# implicit make rules ------------------------------------------------------- 86 87.c$(O): 88 $(CC) -c $(CFLAGS) $< 89 90%.pic$(O): %.c 91 $(CC) -c $(CFLAGS) -DPNG_BUILD_DLL -o $@ $< 92 93 94# dependencies -------------------------------------------------------------- 95 96all: $(EXES) 97 98$(RPNGs)$(E): $(ROBJSs) 99 $(LD) $(LDFLAGS) -o $@ $(ROBJSs) $(RLIBSs) 100 101$(RPNG)$(E): $(ROBJSd) 102 $(LD) $(LDFLAGS) -o $@ $(ROBJSd) $(RLIBSd) 103 104$(RPNG2s)$(E): $(ROBJS2s) 105 $(LD) $(LDFLAGS) -o $@ $(ROBJS2s) $(RLIBSs) 106 107$(RPNG2)$(E): $(ROBJS2d) 108 $(LD) $(LDFLAGS) -o $@ $(ROBJS2d) $(RLIBSd) 109 110$(WPNGs)$(E): $(WOBJSs) 111 $(LD) $(LDFLAGS) -o $@ $(WOBJSs) $(WLIBSs) 112 113$(WPNG)$(E): $(WOBJSd) 114 $(LD) $(LDFLAGS) -o $@ $(WOBJSd) $(WLIBSd) 115 116$(RPNG)$(O): $(RPNG).c readpng.h 117$(RPNG2)$(O): $(RPNG2).c readpng2.h 118$(WPNG)$(O): $(WPNG).c writepng.h 119 120readpng$(O) readpng.pic$(O): readpng.c readpng.h 121readpng2$(O) readpng2.pic$(O): readpng2.c readpng2.h 122writepng$(O) writepng.pic$(O): writepng.c writepng.h 123 124 125# maintenance --------------------------------------------------------------- 126 127clean: 128 $(RM) $(EXES) 129 $(RM) $(ROBJSs) $(ROBJS2s) $(WOBJSs) 130 $(RM) $(ROBJSd) $(ROBJS2d) $(WOBJSd) 131
