1 # Sample makefile for rpng-x / rpng2-x / wpng using 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 shell prompt in the usual way; for example: 12 # 13 # make -f Makefile.unx 14 # 15 # This makefile assumes libpng and zlib have already been built or downloaded 16 # and are installed in /usr/local/{include,lib} or as otherwise indicated by 17 # the PNG* and Z* macros below. Edit as appropriate--choose only ONE each of 18 # the PNGINC, PNGLIBd, PNGLIBs, ZINC, ZLIBd and ZLIBs lines. 19 # 20 # This makefile builds both dynamically and statically linked executables 21 # (against libpng and zlib, that is), but that can be changed by modifying 22 # the "EXES =" line. (You need only one set, but for testing it can be handy 23 # to have both.) 24 25 26 # macros -------------------------------------------------------------------- 27 28 #PNGDIR = /usr/local/lib 29 #PNGINC = -I/usr/local/include/libpng16 30 #PNGLIBd = -L$(PNGDIR) -lpng16 # dynamically linked, installed libpng 31 #PNGLIBs = $(PNGDIR)/libpng16.a # statically linked, installed libpng 32 # or: 33 PNGDIR = ../..# this one is for libpng-x.y.z/contrib/gregbook builds 34 #PNGDIR = ../libpng 35 PNGINC = -I$(PNGDIR) 36 PNGLIBd = -Wl,-rpath,$(PNGDIR) -L$(PNGDIR) -lpng16 # dynamically linked 37 PNGLIBs = $(PNGDIR)/libpng.a # statically linked, local libpng 38 39 ZDIR = /usr/local/lib 40 #ZDIR = /usr/lib64 41 ZINC = -I/usr/local/include 42 ZLIBd = -L$(ZDIR) -lz # dynamically linked against zlib 43 ZLIBs = $(ZDIR)/libz.a # statically linked against zlib 44 # or: 45 #ZDIR = ../zlib 46 #ZINC = -I$(ZDIR) 47 #ZLIBd = -Wl,-rpath,$(ZDIR) -L$(ZDIR) -lz # -rpath allows in-place testing 48 #ZLIBs = $(ZDIR)/libz.a 49 50 #XINC = -I/usr/include # old-style, stock X distributions 51 #XLIB = -L/usr/lib/X11 -lX11 # (including SGI IRIX) 52 #XINC = -I/usr/openwin/include # Sun workstations (OpenWindows) 53 #XLIB = -L/usr/openwin/lib -lX11 54 XINC = -I/usr/X11R6/include # new X distributions (X.org, etc.) 55 XLIB = -L/usr/X11R6/lib -lX11 56 #XLIB = -L/usr/X11R6/lib64 -lX11 # e.g., Red Hat on AMD64 57 58 INCS = $(PNGINC) $(ZINC) $(XINC) 59 RLIBSd = $(PNGLIBd) $(ZLIBd) $(XLIB) -lm 60 RLIBSs = $(PNGLIBs) $(ZLIBs) $(XLIB) -lm 61 WLIBSd = $(PNGLIBd) $(ZLIBd) -lm 62 WLIBSs = $(PNGLIBs) $(ZLIBs) 63 64 CC = gcc 65 LD = gcc 66 RM = rm -f 67 CPPFLAGS = $(INCS) -DFEATURE_LOOP 68 CFLAGS = -O -Wall 69 # [note that -Wall is a gcc-specific compilation flag ("most warnings on")] 70 # [-ansi, -pedantic and -W can also be used] 71 LDFLAGS = 72 O = .o 73 E = 74 75 RPNG = rpng-x 76 RPNG2 = rpng2-x 77 WPNG = wpng 78 79 RPNGs = $(RPNG)-static 80 RPNG2s = $(RPNG2)-static 81 WPNGs = $(WPNG)-static 82 83 ROBJS = $(RPNG)$(O) readpng$(O) 84 ROBJS2 = $(RPNG2)$(O) readpng2$(O) 85 WOBJS = $(WPNG)$(O) writepng$(O) 86 87 STATIC_EXES = $(RPNGs)$(E) $(RPNG2s)$(E) $(WPNGs)$(E) 88 DYNAMIC_EXES = $(RPNG)$(E) $(RPNG2)$(E) $(WPNG)$(E) 89 90 EXES = $(STATIC_EXES) $(DYNAMIC_EXES) 91 92 93 # implicit make rules ------------------------------------------------------- 94 95 .c$(O): 96 $(CC) -c $(CPPFLAGS) $(CFLAGS) $< 97 98 99 # dependencies -------------------------------------------------------------- 100 101 all: $(EXES) 102 103 $(RPNGs)$(E): $(ROBJS) 104 $(LD) $(LDFLAGS) -o $@ $(ROBJS) $(RLIBSs) 105 106 $(RPNG)$(E): $(ROBJS) 107 $(LD) $(LDFLAGS) -o $@ $(ROBJS) $(RLIBSd) 108 109 $(RPNG2s)$(E): $(ROBJS2) 110 $(LD) $(LDFLAGS) -o $@ $(ROBJS2) $(RLIBSs) 111 112 $(RPNG2)$(E): $(ROBJS2) 113 $(LD) $(LDFLAGS) -o $@ $(ROBJS2) $(RLIBSd) 114 115 $(WPNGs)$(E): $(WOBJS) 116 $(LD) $(LDFLAGS) -o $@ $(WOBJS) $(WLIBSs) 117 118 $(WPNG)$(E): $(WOBJS) 119 $(LD) $(LDFLAGS) -o $@ $(WOBJS) $(WLIBSd) 120 121 $(RPNG)$(O): $(RPNG).c readpng.h 122 $(RPNG2)$(O): $(RPNG2).c readpng2.h 123 $(WPNG)$(O): $(WPNG).c writepng.h 124 125 readpng$(O): readpng.c readpng.h 126 readpng2$(O): readpng2.c readpng2.h 127 writepng$(O): writepng.c writepng.h 128 129 130 # maintenance --------------------------------------------------------------- 131 132 clean: 133 $(RM) $(EXES) $(ROBJS) $(ROBJS2) $(WOBJS) 134
