If your application fails to find libpng or zlib entries while linking:
Be sure "-lz" appears after "-lpng" on your linking command.
Be sure you have built libpng, zlib, and your application for the
same platform (e.g., 32-bit or 64-bit).
If you are using the vstudio project, observe the WARNING in
project/vstudio/README.txt.

Using the ./configure script -- 16 December 2002.
=================================================
The ./configure script should work compatibly with what scripts/makefile.*
did, however there are some options you might need to add to configure
explicitly, which previously was done semi-automatically (if you didn't edit
scripts/makefile.* yourself, that is)
CFLAGS="-Wall -O -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/libpng16, or whatever.
If you find that the configure script is out-of-date or is not supporting
your platform properly, try running autogen.sh to regenerate "configure",
"Makefile.in", and the other configuration files. Then try configure again.
