Hi everybody, I’m getting closer to a working driver, but I’m
not there yet. The errors are getting stranger though :-) First of all, when I make my module, I’m getting the
following warnings: WARNING: "ieee1394_bus_type" [/file-location/driver.ko]
undefined! WARNING: "hpsb_send_packet_and_wait" [/file-location/driver.ko]
undefined! WARNING: "dvb_usercopy" [/file-location/driver.ko]
undefined! Just warnings, no errors. Now, when I try to insmod driver.ko, I’m getting the
following errors in dmesg: driver: Unknown symbol dvb_usercopy driver: Unknown symbol hpsb_send_packet_and_wait driver: Unknown symbol ieee1394_bus_type driver: disagrees about version of symbol
dvb_unregister_frontend driver: Unknown symbol dvb_unregister_frontend driver: disagrees about version of symbol
dvb_register_frontend driver: Unknown symbol dvb_register_frontend The first 3 errors are to be expected when you see the
warnings in the make-process, the last 4 are new. But I don’t get why I get those errors... When I look
in /proc/kallsyms, those functions exist: $ cat /proc/kallsyms | grep dvb_usercopy f8de4080 t dvb_usercopy [dvb_core] $ cat /proc/kallsyms | grep ieee1394_bus_type f88eb420 d ieee1394_bus_type [ieee1394] $ cat /proc/kallsyms | grep hpsb_send_packet_and_wait f88d6600 t hpsb_send_packet_and_wait
[ieee1394] $ cat /proc/kallsyms | grep dvb_unregister_frontend f8df0814 r

dvb_register_frontend [dvb_core] I hope there’s someone who can help me out, because I
don’t know what I’m doing wrong :-( Greetings (and happy holidays), Ben |
