1# Sample makefile for rpng-win / rpng2-win / wpng using MSVC and NMAKE. 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# %devstudio%\vc\bin\vcvars32.bat 14# nmake -nologo -f Makefile.w32 15# 16# where %devstudio% is the installation directory for MSVC / DevStudio. If 17# you get "environment out of space" errors, create a desktop shortcut with 18# "c:\windows\command.com /e:4096" as the program command line and set the 19# working directory to this directory. Then double-click to open the new 20# DOS-prompt window with a bigger environment and retry the commands above. 21# 22# This makefile assumes libpng and zlib have already been built or downloaded 23# and are in subdirectories at the same level as the current subdirectory 24# (as indicated by the PNGPATH and ZPATH macros below). Edit as appropriate. 25# 26# Note that the names of the dynamic and static libpng and zlib libraries 27# used below may change in later releases of the libraries. This makefile 28# builds statically linked executables, but that can be changed by uncom- 29# menting the appropriate PNGLIB and ZLIB lines. 30 31!include <ntwin32.mak> 32 33 34# macros -------------------------------------------------------------------- 35 36PNGPATH = ../libpng 37PNGINC = -I$(PNGPATH) 38#PNGLIB = $(PNGPATH)/pngdll.lib 39PNGLIB = $(PNGPATH)/libpng.lib 40 41ZPATH = ../zlib 42ZINC = -I$(ZPATH) 43#ZLIB = $(ZPATH)/zlibdll.lib 44ZLIB = $(ZPATH)/zlibstat.lib 45 46WINLIBS = -defaultlib:user32.lib gdi32.lib 47# ["real" apps may also need comctl32.lib, comdlg32.lib, winmm.lib, etc.] 48 49INCS = $(PNGINC) $(ZINC) 50RLIBS = $(PNGLIB) $(ZLIB) $(WINLIBS) 51WLIBS = $(PNGLIB) $(ZLIB) 52 53CC = cl 54LD = link 55RM = del 56CFLAGS = -nologo -O -W3 $(INCS) $(cvars) 57# [note that -W3 is an MSVC-specific compilation flag ("all warnings on")] 58# [see %devstudio%\vc\include\win32.mak for cvars macro definition] 59O = .obj 60E = .exe 61 62RLDFLAGS = -nologo -subsystem:windows 63WLDFLAGS = -nologo 64 65RPNG = rpng-win 66RPNG2 = rpng2-win 67WPNG = wpng 68 69ROBJS = $(RPNG)$(O) readpng$(O) 70ROBJS2 = $(RPNG2)$(O) readpng2$(O) 71WOBJS = $(WPNG)$(O) writepng$(O) 72 73EXES = $(RPNG)$(E) $(RPNG2)$(E) $(WPNG)$(E) 74 75 76# implicit make rules ------------------------------------------------------- 77 78.c$(O): 79 $(CC) -c $(CFLAGS) $< 80 81 82# dependencies -------------------------------------------------------------- 83 84all: $(EXES) 85 86$(RPNG)$(E): $(ROBJS) 87 $(LD) $(RLDFLAGS) -out:$@ $(ROBJS) $(RLIBS) 88 89$(RPNG2)$(E): $(ROBJS2) 90 $(LD) $(RLDFLAGS) -out:$@ $(ROBJS2) $(RLIBS) 91 92$(WPNG)$(E): $(WOBJS) 93 $(LD) $(WLDFLAGS) -out:$@ $(WOBJS) $(WLIBS) 94 95$(RPNG)$(O): $(RPNG).c readpng.h 96$(RPNG2)$(O): $(RPNG2).c readpng2.h 97$(WPNG)$(O): $(WPNG).c writepng.h 98 99readpng$(O): readpng.c readpng.h 100readpng2$(O): readpng2.c readpng2.h 101writepng$(O): writepng.c writepng.h 102 103 104# maintenance --------------------------------------------------------------- 105 106clean: 107# ideally we could just do this: 108# $(RM) $(EXES) $(ROBJS) $(ROBJS2) $(WOBJS) 109# ...but the Windows "DEL" command is none too bright, so: 110 $(RM) r*$(E) 111 $(RM) w*$(E) 112 $(RM) r*$(O) 113 $(RM) w*$(O) 114
