Installing libpng version 1.0.18 - December 3, 2004
Installing libpng version 1.0.19rc1 - June 13, 2006
Before installing libpng, you must first install zlib. zlib
can usually be found wherever you got libpng. zlib can be
placed in another directory, at the same level as libpng.
Note that your system might already have a preinstalled
zlib, but you will still need to have access to the
zlib.h and zconf.h include files that correspond to the
version of zlib that's installed.
On Unix/Linux and similar systems, you can simply type
./autogen.sh
./configure [--prefix=$HOME]
make check
make install
and ignore the rest of this document.
Or you can use one of the custom-built makefiles in the
"scripts" directory
cp scripts/makefile.system makefile
make test
make install
Or you can use one of the "projects" in the "projects" directory.

Using the ./configure script -- 16 December 2002.
=================================================
The ./configure script should work compatibly with what scripts/makefile.*
did, however there are some options you need to add to configure explicitly,
which previously was done semi-automatically (if you didn't edit
scripts/makefile.* yourself, that is)
CFLAGS="-Wall -O3 -funroll-loops \
-malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \
--with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include
You can alternatively specify --includedir=/usr/include, /usr/local/include,
/usr/include/png12, or whatever.
