When build my driver under kernel 2.6.9.

How to let the “ld” link an existing file?

My makefile:

Obj-m := module.o

Module-objs := a.o b.o c.o

#c.o is an exist object file.

Default:

$(MAKE) -C $(KERNEL_SOURCE) SUBDIRS=$(PWD) modules

But the make do not know the c.o is existed and it request c.s.

Thanks
