I use: --with-mad=/usr/local/arm/2.95.3/arm-linux
which should be similar to your --with-mad=/opt/Qtopia

Make sure you remove config.cache first and do make distclean before 
doing configure, compile.

Did you do `make DESTDIR=/opt/Qtopia install`?
Does mad.h exist in /opt/Qtopia/include ? I do not think so ;-)

Did this work?

Should not make a difference. Focus on static first.

Try the script I added, called "mad".

It cannot correctly determine where the development headers are. Look in 
  /opt/Qtopia/include and or lib if a libmad.h ad libraries can be found.

You compiled for X11 and not for Qtopia here!!! You run Qtopia on the iPaq?

You cannot copy it to /bin, /lib/ etc. if you compile it with 
--prefix=/opt/Qtopia. You told the configure script to compile it for 
running from /opt/Qtopia. So when installing make sure you install it 
relative to /opt/Qtopia. Thus in /opt/Qtopia/bin, 
/opt/Qtopia/lib/videolan/vlc.

In short "make DESTDIR=/opt/Qtopia install".
