1# Sample makefile for rpng-x / rpng2-x / wpng for SGI using cc and make. 2# Greg Roelofs 3# Last modified: 7 March 2002 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? Buy some for friends 8# and family, too. (Not that this is a blatant plug or anything.) 9# 10# Invoke this makefile from a shell prompt in the usual way; for example: 11# 12# make -f Makefile.sgi 13# 14# This makefile assumes libpng and zlib have already been built or downloaded 15# and are both installed in /usr/local/{include,lib} (as indicated by the 16# PNG* and Z* macros below). Edit as appropriate--choose only ONE each of 17# the PNGINC, PNGLIB, ZINC and ZLIB lines. 18# 19# This makefile builds dynamically linked executables (against libpng and zlib, 20# that is), but that can be changed by uncommenting the appropriate PNGLIB and 21# ZLIB lines. 22 23 24# macros -------------------------------------------------------------------- 25 26PNGINC = -I/usr/local/include/libpng16 27PNGLIB = -L/usr/local/lib -lpng16 # dynamically linked against libpng 28#PNGLIB = /usr/local/lib/libpng16.a # statically linked against libpng 29# or: 30#PNGINC = -I../.. 31#PNGLIB = -L../.. -lpng 32#PNGLIB = ../../libpng.a 33 34ZINC = -I/usr/local/include 35ZLIB = -L/usr/local/lib -lz # dynamically linked against zlib 36#ZLIB = /usr/local/lib/libz.a # statically linked against zlib 37#ZINC = -I../zlib 38#ZLIB = -L../zlib -lz 39#ZLIB = ../../../zlib/libz.a 40 41XINC = -I/usr/include/X11 # old-style, stock X distributions 42XLIB = -L/usr/lib/X11 -lX11 43#XINC = -I/usr/openwin/include # Sun workstations (OpenWindows) 44#XLIB = -L/usr/openwin/lib -lX11 45#XINC = -I/usr/X11R6/include # new X distributions (XFree86, etc.) 46#XLIB = -L/usr/X11R6/lib -lX11 47 48INCS = $(PNGINC) $(ZINC) $(XINC) 49RLIBS = $(PNGLIB) $(ZLIB) $(XLIB) -lm 50WLIBS = $(PNGLIB) $(ZLIB) 51 52CC = cc 53LD = cc 54RM = rm -f 55# ABI must be the same as that used to build libpng. 56ABI = 57CPPFLAGS = 58CFLAGS = $(ABI) -O -fullwarn $(INCS) 59LDFLAGS = $(ABI) 60O = .o 61E = 62 63RPNG = rpng-x 64RPNG2 = rpng2-x 65WPNG = wpng 66 67ROBJS = $(RPNG)$(O) readpng$(O) 68ROBJS2 = $(RPNG2)$(O) readpng2$(O) 69WOBJS = $(WPNG)$(O) writepng$(O) 70 71EXES = $(RPNG)$(E) $(RPNG2)$(E) $(WPNG)$(E) 72 73 74# implicit make rules ------------------------------------------------------- 75 76.c$(O): 77 $(CC) -c $(CPPFLAGS) $(CFLAGS) $< 78 79 80# dependencies -------------------------------------------------------------- 81 82all: $(EXES) 83 84$(RPNG)$(E): $(ROBJS) 85 $(LD) $(LDFLAGS) -o $@ $(ROBJS) $(RLIBS) 86 87$(RPNG2)$(E): $(ROBJS2) 88 $(LD) $(LDFLAGS) -o $@ $(ROBJS2) $(RLIBS) 89 90$(WPNG)$(E): $(WOBJS) 91 $(LD) $(LDFLAGS) -o $@ $(WOBJS) $(WLIBS) 92 93$(RPNG)$(O): $(RPNG).c readpng.h 94$(RPNG2)$(O): $(RPNG2).c readpng2.h 95$(WPNG)$(O): $(WPNG).c writepng.h 96 97readpng$(O): readpng.c readpng.h 98readpng2$(O): readpng2.c readpng2.h 99writepng$(O): writepng.c writepng.h 100 101 102# maintenance --------------------------------------------------------------- 103 104clean: 105 $(RM) $(EXES) $(ROBJS) $(ROBJS2) $(WOBJS) 106
