How to Compile a dynamic module in linux on mini2440

Hello.... I want to compile a dynamic module (Hello world) in linux on
mini2440.

Can any one help me to sort out this.

You need the sources and the configuration of the binary kernel you
currently run on your Mini2440. Its build system only needs a valid ARM
toolchain. Everything else happens automagically. Build this kernel and
then build your module against this already built kernel out of tree. Refer
in-kernel documentation in "Documentation/kbuild/modules.txt"
Happy hacking
