I am trying to configure libid3tag.0.15.1b for the arm processor. But it keeps failing on zlib.h.

I check /usr/local/arm/2.95.3/arm-linux/include and there is zlib.h

It finds assert.h, whcih is in the same directory, so why not zlib.h?

Perhaps it actually finds assert.h from a different directory. If you're compiling with gcc, you can add the -v flag to see the search path.

From your transcript above, I can't tell if you're actually invoking a cross-compiler. Normally your configure run would look something more like:

./configure --host=arm-linux CC=arm-linux-gcc
