When compiling modules you better use the kbuild infrastructure, and
then also a kbuild makefile.
The way to use the kbuild infrastructure is to build your
modules with the above command, where $KERNELSRC is
the directory where you have the kernelsrc.
So you should use something like:
make -C /home/sam/src/kernel/v2.4.18/ SUBDIRS=$PWD modules
assuming the src of the kernel is located in
/home/sam/src/kernel/v2.4.18/

Try with a Makefile like this:
[Makefile]
obj-m := myic.o
That should do it.
[Later you can add the clean stuff]
