17 # This makefile expects to be run under the MSYS shell (part of
18 # the MINGW project) and not under CMD.EXE which does not provide
21 # This makefile intends to support building outside the src directory
22 # if desired. When invoking it, specify an argument to SRCDIR on the
23 # command line that points to the top of the directory where your source
31 # Override DESTDIR= on the make install command line to easily support
32 # installing into a temporary location. Example:
34 # make install DESTDIR=/tmp/build/libpng
36 # If you're going to install into a temporary location
37 # via DESTDIR, $(DESTDIR)$(prefix) must already exist before
38 # you execute make install.
41 # If you're using a cross-compiler, add the appropriate prefix (e.g.,
42 # "i386-mingw32msvc-") to the following three commands:
47 MKDIR_P=/bin/mkdir -pv
49 # Where "make install" puts libpng*.a, *png*.dll, png.h, and pngconf.h
