# Sample makefile for rpng-win / rpng2-win / wpng using mingw32-gcc and make. |

|
# The programs built by this makefile are described in the book, |
|
# "PNG: The Definitive Guide," by Greg Roelofs (O'Reilly and |
|
# Associates, 1999). Go buy a copy, eh? Well, OK, it's not |
|
# generally for sale anymore, but it's the thought that counts, |
|
# right? (Hint: http://www.libpng.org/pub/png/book/ ) |
|
# |
|
# Invoke this makefile from a DOS-prompt window via: |
|
# |
|
# make -f Makefile.mingw32 |
|
# |
|
# This makefile assumes libpng and zlib have already been built or downloaded |
|
# and are in subdirectories at the same level as the current subdirectory |
|
# (as indicated by the PNGDIR and ZDIR macros below). It makes no assumptions |
|
# at all about the mingw32 installation tree (W32DIR). Edit as appropriate. |
|
# |
|
# Note that the names of the dynamic and static libpng and zlib libraries |
|
# used below may change in later releases of the libraries. This makefile |
|
# builds both statically and dynamically linked executables by default. |
|
# (You need only one set, but for testing it can be handy to have both.) |
