Thanks for your detailed explaination.I should be
blamed to take $KERNELSRC as a command parameter.:-)

Yeah,it did work right.When using it with "make -C
/workspace/keep/dmt201/kernel/ SUBDIRS=$PWD modules"
command,it found myic.c real problem as following:
myic.c:65:1: warning: "MODVERSIONS" redefined
<command line>:1:1: warning: this is the location of
the previous definition
make[1]: Leaving directory
`/workspace/myfilesystem/target/workdir/ic'
make: Leaving directory
`/workspace/keep/dmt201/kernel'
After removing "#define MODVERSIONS" in myic.c,module
compiling work well without any warning.

OK,I added the clean staff in my Makefile like
clean :
rm myic.o
But I got the mess message as well.
[root at sam ic]# make clean
make: /scripts/pathdown.sh: Command not found
/usr/share/locale/en_US.iso885915/LC_MESSAGES/make.morm
myic.o
It did remove myic.o.Could there any better way to
clean myic.o?
I appreciated your instruction very much.The making
module method is better than my former one.:-)
