Hi.
I've got a simple question - how export symbols from one module, and use
them in another.
I have two modules - 'kvaser' and 'can_master'.
'kvaser' exports some functions, and 'can_master' needs to use call
these functions.
I used EXPORT_SYMBOL, and declared the function extern,
but i still get unresolved symbols.
> insmod kvaser.o
> insmod can_master.o
can_master.o: unresolved symbol can_hw_no_messages
can_master.o: unresolved symbol can_hw_register
can_master.o: unresolved symbol can_hw_get_message
can_master.o: unresolved symbol can_hw_unregister
can_master.o: unresolved symbol can_hw_listen
can_master.o: unresolved symbol can_hw_block
can_master.o: unresolved symbol can_hw_send_message
Looking in /proc/ksyms, i can find the exported symbols from the kvaser
driver, but it they are in a different format than all the others.

[kvaser]
the modules are compiled with:
-D__KERNEL__ -DMODULE -Wall -O2 -Wall -Wstrict-prototypes
-fomit-frame-pointer -fno-strict-aliasing -DEXPORT_SYMTAB
Any ideas appreciated.
