1 # Sample makefile for rpng-win / rpng2-win / wpng using MSVC and NMAKE.

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/ )
11 # Invoke this makefile from a DOS prompt window via:
13 # %devstudio%\vc\bin\vcvars32.bat
14 # nmake -nologo -f Makefile.w32
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.
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.
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.
