[...CUT...]
Many thanks to Massimiliano for his answers, I'm writing the solution to
my problem.
Thanks to my tries on another system, I had the confirmation that the
problem was not due to some compiler, modutils, binutils or other stuff
like that.
After two days I've discovered a simple important rule in writing an
external module makefile (many of you will find that obvious).
Suppose you have to build a module from more than one source file, the
usual foo.c and bar.c. Suppose also that foo.c is the file which
contains the module_init and module_exit functions.
In the makefile you write, when you get to the obj part, you shall avoid
to write
obj-m:=foo.o
foo-objs:=bar.o
In other word, what stays after obj-m (that will be the name of the
module, apart from a ko instead of an o) shall have a different name
from the file which contains the module_init and exit (I thought I had
to use just that file and filename). I had done exactly this error. So
the following would be correct:
obj-m:=name.o
name-objs:=foo.o bar.o
with whatever name != foo.
Thanks again!
Bye,
