2.4makefile Problems

2.4makefile-general Linux technology-Linux programming and kernel information. For more information, see the following section. Hello, everyone

I have written a 2.4 driver named mymodule. c.

An error occurred while writing makefile. My makefile is as follows:
# Makefile2.4
KVER = $ (shell uname-r)
KDIR =/lib/modules/$ (KVER)/build
OBJS = mymodule. o
CFLAGS =-d1_kernel _-I $ (KDIR)/include-DMODULE-d1_kernel_syscils _-DEXPORT_SYMTAB-O2-fomit-frame-pointer-Wall-DMODVERSIONS-include $ (KDIR) /include/linux/modversions. h

All: $ (OBJS)
Mymodule. o: mymodule. c
Ld-r-o $ @ $ ^
Clean:
Rm-f *. o


In Red Hat 9, the following problem occurs after make:
No rule to make target 'mymodule. C', needed by mymodule. o
I have just learned how to write the makefile driver. Thank you!
