| |
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.
d3d27070 can_hw_register_R__ver_can_hw_register [kvaser] d3d27090 can_hw_unregister_R__ver_can_hw_unregister [kvaser] d3d270b0 can_hw_listen_R__ver_can_hw_listen [kvaser] d3d270c4 can_hw_block_R__ver_can_hw_block [kvaser] d3d270e8 can_hw_send_message_R__ver_can_hw_send_message [kvaser] d3d270f8 can_hw_get_message_R__ver_can_hw_get_message [kvaser] d3d27108 can_hw_no_messages_R__ver_can_hw_no_messages [kvaser] d3d27000 __insmod_kvaser_O/home/afu/cvs/dtu/49422/canbus/src/kvaser.o_M3B01709C_V132100 [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.
